Even the most health-conscious among us can go a little crazy on snacks and drinks during the holidays and at springtime and during the summer months, and before we know it, we are back at the holidays. Really, where does the time go? If we are having fun with people we love and care about, then that may also be another reason for indulging in our favorite snacks and drinks. So, when is it not a perfect reason or season to fall victim of the snack trap?

Thankfully, you can kind of have your cake and eat it, too. It’s OK to indulge a little in the foods you love, as long as you know how to get your body back on track. One of the best ways to help your body feel like it’s working at an optimal level is to support the bodies natural detoxification. Your organs are already incredibly well-suited for detoxing things, such as heavy metals, pathogens, and other deleterious compounds from its system. However, sometimes, especially when it’s overloaded and working overtime, your body can use a little bit of detox support.

Eating these foods regularly will help you feel energized and clear-minded. You’ll also notice that side effects of chronic inflammation caused by toxins will disappear. For many people, common side effects are bloating, indigestion, and weight gain, so in a sense, these are “flat tummy” foods, too!

  1. Beets: The root veggie is available year round, but be sure to grab a few at the farmers market before your next summer cookout. Beets support healthy liver function and help it filter out toxins all thanks to something called betaine. This compound, unique to raw beetroot, encourages the liver to cleanse itself and promotes healthy bile production. Try wrapping beets in foil and throwing them on the grill next time you BBQ!
  2. Grapefruit: Juicy, sweet, and tart, grapefruits are good to keep on hand the morning after a heavy meal. The antioxidants in the citrus fruit protect cells from free radical damage. Grapefruit is also very high in fiber, which acts like a broom for your digestive system, sweeping out the gut and intestines until everything is clean and good as new.
  3. Dandelion Root Iced Tea: Not exactly something you can snack on, but still an excellent detoxifying ingredient to have in your pantry! Dandelion Root promotes the production of bile in the liver. In other words, it helps your liver break down and cleanse your internal organs. Make a big batch and sip on this stuff the morning after a night out.
  4. Asparagus: According to the Journal of Food Science, the amino acids and minerals found in asparagus protect liver cells. Because so much of detoxification happens in the liver, it’s important to support this critical organ however possible.
  5. Avocado: Next time you’re feeling a little woozy after one too many skinny margaritas, whip up some avocado toast. A study published in The Journal of Agricultural Food Chemistry found that of all fruits, avocado has the most liver-friendly benefits. It’s even able to reverse liver cell damage!

Like it or not: Broccoli may be good for the gut

For the broccoli haters of the world, researchers may have more bad news: the vegetable may also help promote a healthy gut.

Image result for Like it or not: Broccoli may be good for the gut

 

In a study, when mice ate broccoli with their regular diet, they were better able to tolerate digestive issues similar to symptoms of leaky gut and colitis than mice that were not placed on a broccoli-supplemented diet, according to Gary Perdew, the John T. and Paige S. Smith Professor in Agricultural Sciences, Penn State. He added that other vegetables, such as Brussels sprouts and cauliflower, may also have similar gut health properties. “There are a lot of reasons we want to explore helping with gastrointestinal health and one reason is if you have problems, like a leaky gut, and start to suffer inflammation, that may then lead to other conditions, like arthritis and heart disease,” said Perdew. “Keeping your gut healthy and making sure you have good barrier functions so you’re not getting this leaky effect would be really big.”

Good intestinal barrier function means that the gastrointestinal (GI) tract is helping protect the intestines from toxins and harmful microorganisms while allowing nutrients to pass into the system, he said. According to Perdew, the key to the process may be a receptor in the gut called Aryl hydrocarbon receptor, or AHR. The receptor helps the body regulate its reaction to certain environmental contaminants, as well as triggers other responses to toxin exposure. The researchers, who released their findings in the current issue of the Journal of Functional Foods, suggest that cruciferous vegetables, such as broccoli, brussels sprouts and cabbage contain an organic chemical compound called indole glucosinolates, which breaks down into other compounds, including indolocarbazole (ICZ) in the stomach.

When ICZ binds to and activates the Aryl hydrocarbon receptor (AHR) in the intestinal lining, it aids in maintaining a healthy balance in the gut flora and immune surveillance, and enhances host barrier function, according to the researchers. This may help prevent diseases, such as various cancers and Crohn’s Disease, caused by inflammation of the lining of the gut. According to Perdew, hyper-activating the AHR can cause toxicity, but using broccoli to activate the receptor locally, in the gut, rather than systemically might help avoid some of these problems. “Dioxin, for example, activates this receptor, and if you hyper-activate it with dioxin, it will cause toxicity,” said Perdew. “What we were interested in is: Could you locally activate the receptor naturally at a level that would cause only modest AHR activation in the gut, but not cause systemic activation, which could possibly lead to negative effects?”

The researchers used two genetic lines of mice in the study to focus on AHR. One line had a low ability to bind ICZ to AHR, while the other line had a high ability to bind ICZ to AHR. They added 15 percent broccoli to the diets of both groups of mice. After adding a substance that causes digestive problems, the researchers said that the mice with a higher ability to bind ICZ to the AHR were protected from a chemical that induced digestive problems, but the mice with the lower affinity suffered from the toxic insult.

For humans, the amount in the experiment would be equivalent to eating about 3.5 cups of broccoli each day, according to Perdew. “Now, three and a half cups is a lot, but it’s not a huge amount, really,” said Perdew. “We used a cultivar — or variety — with about half the amount of this chemical in it, and there are cultivars with twice as much. Also, brussels sprouts have three times as much, which would mean a cup of brussels sprouts could get us to the same level.”

Because people with certain digestive conditions like colitis, are often warned to avoid too much roughage in their diets, future research may include determining the best ways for people to consume broccoli, or other veggies with similar effects, to receive the same health benefits, without causing any other associated digestive problems from the fibrous vegetables.

Keto Diet Can Help You Live Longer, Researchers Say

Two recent studies concluded that the low-carbohydrate diet can increase lifespan. However, there is still plenty of controversy surrounding the Keto diet.

keto-infographic-preview.jpg

Has the fountain of youth been sitting on your dinner plate? Two new scientific studies independently concluded that a ketogenic diet increased lifespan and preserved memory and motor function in mice. For advocates of the diet, the results are another feather in their cap, but the question remains if the science really outweighs the hype for humans. “The conclusion we draw out of this is that it’s a robust effect,” said Dr. Eric Verdin, president and chief executive officer of the Buck Institute for Research on Aging and senior author of one of the papers, in a press release. “The two studies reinforce each other because they both show the same global effect on healthspan.”

Many are taking notice. This is a really exciting finding and long overdue,” Susan A. Masino, Ph.D., a professor of applied science at Trinity College in Connecticut, told Healthline. “[Ketogenic diets] mimic the metabolic state of fasting or caloric restriction — which has many similar benefits.” Masino has spent years researching the ketogenic diet, metabolism, and brain health — that is, how what we eat affects our brains.

How the studies were conducted

In Verdin’s study, some mice were fed between 70-90% of their daily food calories from fat. That was compared with control groups receiving only 13-17% from fat, with carbohydrate calories making up the bulk of the difference. The mice on higher fat diets had longer lives, lower midlife mortality rates, and performed better on tests pertaining to certain cognitive functioning. The results “clearly demonstrate that lifespan is increased in mice consuming a ketogenic diet,” compared with a control group, the authors wrote.

However, it’s impossible to say that such a conclusion could be reproduced in humans. As such, some experts are more measured in their assessment of these findings. Susan Weiner, MS, RDN, CDE, CDN, a dietitian and diabetes educator, agrees that the results are promising, but she cautions that it is still “too soon to recommend” the diet to many individuals.

Keto diet is controversial

The ketogenic diet has become pervasive in the United States in both popular culture and fitness circles for its myriad health benefits, but it remains contentious. The diet is based on the simple premise that when carbohydrate intake is drastically lowered or stopped entirely, the body must find a new primary source of energy. That source is fat. Ketosis is different from ketoacidosis, which is the leading cause of death of people with diabetes under 24 years of age.

Ketosis is identified by the presence of ketones in the bloodstream, a chemical that the body produces when it burns stored fat. The ketogenic diet has proven effective in helping to control seizures in some people with epilepsy. Advocates have also hailed its ability to help shed pounds. These new results, Masino said, are further proof of what some researchers, herself included, have believed for years.

However, any time a diet, scientifically backed or not, takes over Americans’ dinner plates, there are bound to be complications. A number of problems individuals can have with the diet have been pointed out in several articles. These include the risk of muscle loss, fatigue, and, of course, the many health issues associated with the yo-yo or fad dieting and with that story, many experts were at odds with each other.

However, Weiner and Masino both agree that for the average American, cutting down on carbs is probably a good thing (BUT, you DO want to make sure the carbs you do intake are whole grains!). “Most adults would benefit from reducing the overall amount of carbohydrate in their diet significantly,” said Masino. “Following a strict ketogenic diet is probably not necessary or realistic for most people unless they have very specific health goals.”

Trying to stay on the Keto diet

The “unrealistic” aspect of the ketogenic diet is that it can actually be difficult to maintain. It requires a strict adherence to a low-carbohydrate, high-fat diet, with little wiggle room for “cheat meals,” and absolutely no sweets or alcohol (O.K. I’m out for sure!). “In any kind of nutrition change there has to be sustainability,” said Weiner. For individuals who are out to lose weight, choosing a difficult diet can be taxing and may cause further setbacks rather than help.

“When you stop short, it does affect people feeling bad about themselves because they can’t keep up with it necessarily at the pace that it’s being recommended,” Weiner said. “So they feel it’s another failure in their trying to lose weight.” The ketogenic diet has been called “antisocial” because dining out becomes difficult, depending on how strictly one is adhering to the diet. “It can be very socially isolating,” said Weiner.

Even when preparing food at home, time management and cost are also factors for individuals who want to cook their own meals. “The social and economic situations affect this decision as well,” said Weiner. The bottom line is that individuals hoping to embark on a nutritional diet should be aware of the multifold ways in which it can impact their lives, beyond potential health benefits or harms. While this new research on the ketogenic diet is exciting, there still remains significant work to be done in human trials. Even then, it may not be beneficial for everyone.

However, as interest in it continues to grow among the general public, and the more informed decision an individual can make about their diet, the better. Weiner said proponents of this diet suggest that our current nutritional habits may lead to an increasing incidence of obesity, prediabetes, cancer and type 2 diabetes. More studies are needed to determine if the ketogenic diet should be recommended for those at high risk for developing these conditions. For most Americans, having to adhere to a strict ketogenic diet is more difficult than taking more simple dietary steps such as eating fewer sweets and carbohydrates, and eating more fresh vegetables.

5 Smart Carb Swaps

pinterest_5-smart-carb-swaps.png

 

Eating fewer carbs does not mean giving up everything you love. A few easy changes can make a big difference in how much you consume. Instead of choosing carb sources loaded with sugar, fat, and calories, opt for more nutrient-dense alternatives filled with fiber, heart-healthy fats, and whole grains. You’ll be surprised at much you love the alternatives below and how delicious eating low-carb can be.

1. BBQ Baked Beans

GOOD: Beans are full of fiber.

BAD: Lots of sugar in the sauce—13g for a total of 32g carbs.

BETTER: Black beans with sautéed red bell pepper, jalapeño, lime, and fresh cilantro. 10g fewer carbs and an additional 1.5g fiber.

2. Salad Dressings

GOOD: You’re eating salad!

BAD: Dressing choices, such as honey mustard (one of my favorites!!) and raspberry vinaigrette contain roughly 7g refined carbs per 2 tablespoons, all from sugar. And most light or fat-free dressings add sugar to make up for fat.

BETTER: Opt for oil and vinegar-based dressings instead; you’ll get zero carbs and lots of heart-healthy fats.

3. Apples with Low-Fat Caramel Dip

GOOD: You’re eating apples—25g balanced carbs and 4g fiber.

BAD: That caramel sauce has 26g carbs in just 2 tablespoons, all from sugar.

BETTER: Swap caramel for 1 tablespoon peanut butter. You’ll add 4g filling protein.

4. Cracker Jacks

GOOD: Whole grains and nuts.

BAD: The caramel adds 30g refined-sugar carbs per cup.

BETTER: Lightly salted oil-popped popcorn and nuts.

5. Mashed Taters

GOOD: More veggies.

BAD: No skin = 2g less fiber.

BETTER: Mashed butternut squash has just 47 calories, 12g carbs, and 4g fiber per ½ cup. Add a teaspoon of butter for 34 calories and 2.4g sat fat.

Not bad alternatives! And if you want to take your health goals to the next step, check out the challenge.

Is IBS a Gut–Brain–Microbiome Axis Disorder?

 

gut-brain-axis.jpg

Irritable Bowel Syndrome (IBS) is an extremely common gastrointestinal (GI) disorder that significantly reduces the quality of life. Treatment options for IBS have long been limited to symptom management. However, a new understanding of IBS has recently emerged, in which a dysfunctional gut–brain–microbiome axis is responsible for the development and progression of the disorder. Right now, you may be asking yourself “How does a dysregulated gut–brain–microbiome axis promote IBS and what therapeutic measures can be used to modulate this axis and reverse the course of the disease?” Well, let’s find out!

What is the gut–brain–microbiome axis?

IBS has an extremely high worldwide prevalence; it is estimated to affect approximately 10-25% of people in developed countries. Despite its vast influence, an understanding of the pathophysiology of this disorder has remained elusive for many years. In addition to abdominal pain, bloating, and abnormal bowel movements, IBS adversely impacts brain function and has been linked to psychiatric disorders such as anxiety and depression. Furthermore, research suggests that people with IBS have an altered gut microbiota compared to healthy individuals. These findings have led to the development of a new understanding of IBS, in which the interrelationship between gut symptoms, mental health, and the microbiome is mediated by the gut–brain–microbiome axis.

The gut–brain–microbiome axis connects the body’s central nervous system (CNS), which houses the brain and spinal cord, with the enteric nervous system (ENS) of the GI tract. This axis facilitates bidirectional neural, hormonal, and immunological communication between the gut and brain. The microbiome is the third key component of this axis. It serves as an intermediary between the gut and brain since the microbes it contains produce metabolites that relay messages to both organs. When the gut–brain–microbiome axis is in balance, the digestive system and brain function optimally. Conversely, dysregulation of this axis may initiate IBS and influence its progression and severity.

The microbiome is altered in IBS

Over the past several years, numerous studies have documented alterations in the gut microbiota of people with IBS relative to healthy people. This has led researchers to postulate that the microbiome may play a key role in the pathogenesis of IBS. In people with IBS, proportions of specific bacterial groups are altered and the diversity of microbial populations is reduced. Researchers have observed decreased levels of Lactobacilli and Bifidobacteria and an increased prevalence of pathogenic anaerobic organisms such as E. coli and Clostridia in fecal samples from IBS patients. In addition, IBS patients exhibit an increased Firmicutes-to-Bacteroidetes ratio.

There are several factors that may lead to microbiome disruption and the onset of IBS. These include antibiotic use, infection, diet, and stress. Stress is perhaps one of the more insidious factors that contribute to IBS; while dietary changes and treatment for gut infections can be relatively simple to institute, stress is an entirely different beast that must constantly be managed. However, the significance of stress and the psychological toll it creates in IBS cannot be understated, given our understanding of the gut–brain–microbiome axis.

The psychological toll of IBS

IBS sufferers have long understood the connection between their gut symptoms and mental health. Indeed, mental health issues such as anxiety and depression are a common comorbidity of IBS. However, this problem has only recently begun to receive the attention it deserves from the medical community, with the scientific discovery of neural links between the gut and brain in the gut–brain–microbiome axis. Further investigation into the psychological health of IBS patients has found that they exhibit a maladaptive stress response. This includes an exaggerated response to stress and an inability to appropriately shut down the stress response once the stressor is removed. IBS patients also demonstrate visceral hypersensitivity, a condition that increases the level of attention paid to gut symptoms, thus perpetuating anxiety about IBS. There is also evidence that people with IBS may experience stress-related deficits in cognitive function.

The enhanced stress response, anxiety, and altered cognition found in IBS patients may be due in large part to the influence of their gut microbes. There are several mechanisms by which gut microbes affect the gut–brain–microbiome axis. Via the axis, an altered gut microbiota can send neural signals from the gut to the brain, leading to the heightened stress response and increased visceral hypersensitivity characteristic of IBS. This promotes a sustained level of attention to the gut in IBS patients and an inability to “turn off” anxiety surrounding gut symptoms (I think this research is speaking to me 🧐). Gut microbes also alter the availability of tryptophan, an amino acid required to produce the mood-regulating neurotransmitter serotonin. Gut microbes influence the release of immune system mediators and glucocorticoids, which can heighten intestinal pain in IBS. Finally, pathogenic gut microbes can also initiate a proinflammatory state that increases intestinal permeability, resulting in the leakage of neuroactive metabolites from the gut into the CNS, where they have adverse effects on cognition.

Stress, in turn, has harmful effects on the intestinal microbiota. Stress increases intestinal permeability, allowing bacteria and bacterial antigens to cross the epithelial barrier into the bloodstream, inducing an immune response that alters the microbiome. Stress hormones, including epinephrine and norepinephrine, also increase the virulence of gut pathogens by enhancing the availability of iron, which the pathogens use to fuel their activities. Increased levels of gut pathogens may further exacerbate IBS.

Clearly, an imbalanced gut microbiome and an unhappy brain walk hand in hand. The complex relationship between the gut, brain, and microbiome in IBS creates a vicious cycle of intestinal symptoms, stress, and poor mental health. To break this vicious cycle, the gut–brain–microbiome axis must be repaired.

Repairing the gut–brain–microbiome axis to treat IBS

To successfully treat IBS, strategies must be employed that address each component of the gut–brain–microbiome axis. Modulation of the axis with dietary changes, prebiotics, probiotics, select antibiotics, and stress-reduction strategies offer a holistic means of treating IBS.

Diet and prebiotics

Significant positive changes can be induced in the gut–brain–microbiome axis through the implementation of dietary modifications and prebiotic supplementation. One dietary approach that has received substantial attention in the treatment of IBS is the low-FODMAP diet. Briefly, gut bacteria metabolize FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), which include various types of fermentable dietary fibers, into short-chain fatty acids (SCFAs). High levels of two SCFAs, acetic acid, and propionic acid, have been associated with GI symptoms, anxiety, depression, and reduced quality of life in IBS patients. Reducing dietary intake of FODMAPs can lower levels of these SCFAs and therefore alleviate IBS symptoms.

However, research on the low-FODMAP diet for IBS conflicts with other studies suggesting that prebiotics, a type of fermentable fiber, improve both guts- and brain-related symptoms of IBS. The regular consumption of fructooligosaccharides (FOSs) has been found to reduce GI symptoms and improve quality of life markers such as anxiety and sleep in people with functional bowel disorders. Prebiotics also offer brain-health benefits; the intake of galactooligosaccharides (GOSs) increases hippocampal levels of the brain-derived neurotrophic factor, a protein involved in normal brain function, and N-methyl-D-aspartate (NMDA) receptors, which regulate brain plasticity and memory. More research is needed to understand the divergent responses to low-FODMAP diets and prebiotics in IBS patients. Clinically, practitioners should encourage patients to experiment with FODMAPs and prebiotics and find what works best for them.

Probiotics

Probiotics are another promising treatment option for IBS since they modulate both the gut and the brain components of the gut–brain–microbiome axis. Supplementation with Bifidobacterium infantis has been found to improve gut-related symptoms of IBS by reducing abdominal pain and bloating and normalizing bowel movements, while also inducing antidepressant effects through the augmentation of plasma tryptophan levels, increasing levels of the “feel good” neurotransmitter, serotonin. Bifidobacterium animalis is effective for promoting intestinal motility and reducing abdominal discomfort in IBS-C (constipation) patients. Lactobacillus acidophilus supplementation reduces visceral hypersensitivity to IBS by activating opioid and cannabinoid receptors, thus ameliorating intestinal pain and reducing hypervigilance to GI sensations. Finally, probiotic strains that repair the intestinal barrier may reduce the leakage of neuroactive metabolites from the gut into the systemic circulation, protecting brain function.

Antibiotics

Mark Pimentel, a noted small intestinal bacterial overgrowth (SIBO) researcher, has found that up to 85% of IBS patients have SIBO. However, other research suggests that this may be an overestimation, due to the high false positive rate associated with the lactulose breath test used to diagnose SIBO. While not a cure-all, the eradication of SIBO using specific antibiotics, such as rifaximin, may benefit some cases of IBS.

Stress reduction

Chronic stress perpetuates the vicious cycle of IBS by altering the gut microbiota, increasing gut pathogen virulence, and promoting intestinal permeability. The implementation of stress reduction strategies is crucial for breaking the cycle and restoring health to the gut–brain–microbiome axis. While there are many stress-reducing practices to choose from, three in particular—yoga, exercise, and mindfulness meditation—have demonstrated IBS-specific benefits. Yoga has exploded in popularity in recent years and has become the subject of extensive scientific investigation. A recent study found that a yoga practice consisting of postures and breathing exercises beneficially modulates gut and brain function by reducing sympathetic nervous system activity and increasing parasympathetic activity, making it an effective remedial therapy for IBS.

A generalized exercise program may also benefit the gut–brain–microbiome axis and reduce symptoms of IBS. Exercise increases GI motility, reduces intestinal gas retention, relieves stress, and increases the number of beneficial microbial species in the gut. Finally, mindfulness training is another beneficial stress reduction strategy for IBS. Mindfulness training (MT) promotes nonreactive awareness to emotional and sensory experiences, such as GI symptoms, and has been found to beneficially alter pain processing. An eight-week course of mindfulness training in women with IBS significantly reduced gut-focused anxiety and abdominal pain, thus breaking the vicious cycle of stress and intestinal symptoms.

A diagnosis of IBS no longer needs to be vague and frustrating for people. The newfound knowledge of the gut–brain–microbiome axis, and the variety of treatments that can be used to modulate it, offers IBS patients the possibility of a full recovery.

Gluten intolerance appears largely undiagnosed in Canada

Research on a large sample of Canadians suggests that most people with celiac disease don’t know they have it.

70ed5681fb70fdd06614c77e5f4c852d--vitamin-deficiency-difference.jpg

Ahmed El-Sohemy, a professor of Nutritional Science at the University of Toronto, and his colleagues studied the bloodwork of almost 3,000 Canadians and found that one in 114 (or almost one per cent) had elevated antibodies that indicate they suffered from celiac disease, which causes gastric distress and other symptoms. However, the vast majority, almost 90%, were unaware they had the disease. The data was collected about a decade ago, just before public awareness about the potential problems with gluten skyrocketed. The study, published in the journal BMJ Open, is the first to screen for celiac antibodies in a Canadian population. It confirms previous research suggesting that Caucasians are more susceptible to celiac disease than other ethnocultural groups. Although the number of South and East Asians screened in the Canadian study was small, none were found to have the disease. Intriguingly, though, a genetic variant that puts people at high risk for celiac disease was almost as high in the South Asian samples as the Caucasian ones, suggesting that other factors could play a role in who goes on to develop the disease.

“This hopefully should just raise awareness that despite the gluten-free craze there are a lot of people who still don’t know they have celiac disease,” says El-Sohemy. “It’s important for people to understand that celiac disease is not a single clear symptom — it manifests itself in different ways. Symptoms could be fatigue, gastro-intestinal, or other problems. These symptoms are so diverse that doctors have a difficult time pinpointing the cause. Gluten intolerance is not usually the first thing that comes to their mind.”

Adding to the diagnostic confusion, reactions to gluten are not often immediate and acute, El-Sohemy says. “It’s not like lactose where you feel bad within a day after consuming it. Gluten causes damage to the intestinal lining, which results in malabsorption of vitamins and other nutrients, and the effects of those nutrient deficiencies are quite varied.” El-Sohemy believes people with a genetic susceptibility to celiac disease should consider blood tests to determine whether they have the disease if they present with any of the disease symptoms. His analysis of blood samples from Canadians of South Asian heritage suggests that genetic predisposition is only one piece of the celiac puzzle. Future research may focus on the timing of exposure to gluten as well as the role of gut bacteria.

As for why so many non-celiac sufferers feel better after giving up gluten, El-Sohemy speculates the real issue is “because they stopped eating heaping servings of pasta, white bread and other sources of processed carbohydrates.”

Is an Anti-Inflammatory Diet the Best for You?

Fans of anti-inflammatory diets say they can transform you inside and out. Is this another  “health” fad…or do we all really need to go AI?

Foods that fight inflammation-infograph.png

An anti-inflammatory diet=less pain, happy gut, more energy, and more! This diet may be buzzy, but the tenets of an AI diet; more plants, less sugar, no refined stuff, is far from a passing fad. “Who needs to eat a more anti-inflammatory diet? Everyone,” says Barry Sears, PhD, creator of The Zone diet, who has spent decades studying chronic inflammation. Here’s the lowdown on inflammation, and how to fight it with food.

What the heck is inflammation, anyway?

Believe it or not, inflammation starts as a good thing. It happens when your immune system sends out white blood cells and “warrior” compounds, such as eicosanoids to attack invading viruses, bacteria, or toxins. A classic example of normal inflammation: Pain, heat, redness, and swelling around a wound or injury (think of a tender sprained ankle). “There’s a separate response called ‘resolution’ that brings the dogs of war back to their barracks and heals your tissues,” says Sears. “The first phase of inflammation causes cellular destruction, and the second phase, resolution, begins cellular rejuvenation. As long as those phases are balanced, you stay well.”

However, for most of us, the balance never happens. That’s because sugar, refined grains, and saturated fat can also trigger an inflammatory immune response, notes Sears, and the typical Western diet is packed with them, meaning we’re inflaming our bodies over and over, every time we eat. Meanwhile, guess what the average American gets way too little of? Fruits, non-starchy veggies, and fatty fish. Fruits and vegetables are packed with antioxidants that help cool things down and reduce the intensity of the initial inflammatory response and fatty fish, a great source of omega-3 fatty acids, can help your body move into the resolution phase.

Air pollution and environmental toxins also trigger your immune system in the same way, but “most of the chronic, extra inflammation in our bodies is diet-related,” says Sears. In arteries, chronic inflammation can lead to heart disease. In the brain, it’s linked to anxiety and depression. In your joints, it causes swelling and pain. In the gut, inflammation throws off the balance of helpful bacteria and causes direct damage to the lining of the intestines, says Mark Hyman, MD, director of the Center for Functional Medicine at the Cleveland Clinic and author of The Blood Sugar Solution: 10-Day Detox Diet. This may contribute to IBS, food sensitivities, autoimmune diseases, and even obesity, research suggests.

In contrast, research shows that following a more anti-inflammatory style of eating may reduce the risk of heart disease, obesity, and some cancers and may even extend your life, says Frank Hu, MD, professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health. Other claims about anti-inflammatory diets, such as reversing autoimmune disease (the goal of the Autoimmune Protocol, an extremely restrictive AI diet) or improve mental health, have less solid proof, he says.

How to spot an anti-inflammatory diet

There isn’t just one specific “AI Diet,” unlike Atkins or South Beach. Sears’s Zone diet and Dr. Hyman’s Detox are both highly anti-inflammatory, as is the soy-heavy plan from integrative medicine guru Andrew Weil, MD. Paleo and Whole30 diets are both AI, as well. However, the plan with the most research-backed anti-inflammatory credibility is the traditional Mediterranean diet, emphasizing fruits, vegetables, whole grains, legumes, fish, and olive oil. Several very large studies, including the famed Nurses’ Health Study, have found that people who follow a Mediterranean pattern of eating have lower levels of the inflammatory markers C-reactive protein and interleukin-6 in their blood compared with those who do not. This may be one reason the Mediterranean diet is linked to so many health benefits, from keeping weight down to slashing heart and stroke risk, notes Dr. Hu.

The goals of an AI plan are simple: Cut back on foods that trigger an inflammatory response and eat more of the foods that heal damage. While there are some variations in what’s allowed and what isn’t, most AI plans share an emphasis on eating whole, minimally processed foods, non-starchy vegetables, monounsaturated fats, such as olive and avocado oil, colorful berries and other fruits, omega-3s from fatty fish (or supplements), and avoiding added sugar and refined grains. That said, your plate may look a little different from your friend’s or coworker’s, and that’s the way it should be, says Dr. Hyman. Some people thrive on a grain-free Paleo plan, while others would rather die than give up bread. Food sensitivities also play a role: “People react to foods differently, and if someone has a sensitivity to a particular food, it will lead to cytokine production and an increase in other inflammatory chemicals,” says Dr. Hyman. If you suspect you have a sensitivity, talk to your doctor or a dietitian, who can design an elimination diet to help ID the culprit.

What’s off the menu?

While all AI plans give a thumbs-up to veggies, fatty fish, and olive oil, the foods you can’t eat vary. Women with a history of eating disorders take note: “Restricting whole food groups can be triggering,” says Sonya Angelone, RDN. Here is what’s not allowed in four different diets:

Autoimmune protocol: Nightshade vegetables (tomatoes, eggplants,peppers), nuts, seeds, eggs.

Paleo: All grains, dairy, legumes, (chickpeas, lentils, beans, peanuts).

The Zone Diet: All refined grains, white potatoes.

Mediterranean Diet: Added sugar, refined sugar.

So what exactly do you eat?

You don’t have to follow any AI diet perfectly to make a big impact. A healthy body is built to handle the occasional onslaught of inflammation (like having a cupcake at a party); it’s the regular, consistent consumption (and overconsumption) of inflammatory foods, such as sugar and saturated fat that’s linked to serious disease, says Sonya Angelone, RDN, a spokesperson for the Academy of Nutrition and Dietetics. A 2012 study of nearly 2,000 people, for example, found that those who ate the most sweets over two years had significantly higher levels of interleukin-6 than people who ate more veggies, fruits, and whole grains. That’s why it’s more important to eat an overall “super” diet rather than focus on individual superfoods, says Angelone. “If you’re regularly eating a bunch of doughnuts along with a bunch of anti-inflammatory veggies, you’re still harming your body,” adds Dr. Hyman. Follow these AI guidelines on most days:

1. Aim for half to two-thirds of your plate to be nonstarchy vegetables. Greens of all kinds, mushrooms, summer squash, beets, cauliflower…the list goes on and on, as well as at breakfast, too, says Dr. Hyman. They’re packed with gut-balancing fiber and powerful antioxidants.

2. Limit added sugar and sweet drinks. That includes fruit juices and natural sweeteners, such as honey, says Dr. Hyman. In a small 2005 study, people who were fed a high-sugar diet for 10 weeks had significantly elevated blood levels of haptoglobin, an inflammatory marker that in high concentrations is associated with diabetes, heart attack, stroke, and obesity, compared with controls.

3. Eat fish. Especially fatty kinds, such as salmon, mackerel, herring, and anchovies, or take omega-3 supplements, at least 1,000 milligrams daily, says Dr. Hyman.

4. Nix white flour and limit other flour-based foods. Focus on whole, intact grains, such as quinoa, brown rice, and bulgur wheat instead of loading up on whole-grain crackers, breads, and tortillas. Even 100% whole-grain flour will cause a spike in blood sugar that exacerbates inflammation, especially for people with insulin resistance, metabolic syndrome (i.e., prediabetes), or diabetes, so use them moderately, says Sears.

5. Choose fats carefully. The most abundant saturated fats in our diet contain the same fatty acids as do fragments of the cell walls of many bacteria. No wonder our immune system sees a bacon cheeseburger as a threat! Limit saturated fats and skip vegetable oils that are high in omega-6 fats, such as safflower and corn oils. Opt instead for olive, avocado, or walnut oil. “It might sound tough, but if you think about it, it’s exactly how your grandmother probably told you to eat!” says Sears, and a diet endorsed by your nana? Now that sounds like a plan.

Yes, you might lose some weight

Going AI doesn’t automatically mean you’ll drop pounds, says Angelone, especially if your weight is in a healthy range to begin with. However, research does suggest that an AI diet packed with veggies and low in sugar and refined carbs can help with weight loss goals. “You feel fuller on fewer calories because the high-fiber foods have so much more volume,” she says. The healthy fats in an AI plan may also play a role: A large, five-year study published in 2016 found that people who ate a veggie-and fat-rich Mediterranean diet lost more weight than those who went on a low-fat plan.
