“Anti-inflammatory” is printed on everything from turmeric shots to celery juice, and it is hard to know what is real. Chronic low-grade inflammation does matter for men over 35, because it travels with heart disease, diabetes and belly fat. But the foods with the best evidence are boring staples, not miracle powders, and many of them are already in Indian and Latin American kitchens.
Key takeaways
- Chronic low-grade inflammation is a persistent, quiet immune activation linked to heart disease, type 2 diabetes and fatty liver. It is driven largely by inactivity, excess body fat, poor diet and stress.
- The strongest evidence is for whole eating patterns, especially Mediterranean-style eating, not single “superfoods”.
- In the PREDIMED trial, a Mediterranean diet with extra-virgin olive oil or nuts cut major cardiovascular events by about 30% versus a low-fat diet.
- Foods with good support: vegetables, fruit, legumes, whole grains, nuts, seeds, olive oil, fish, and herbs and spices used generously in cooking.
- Overhyped: nightshade-free diets, fears about all seed oils, and high-dose turmeric supplements, which carry real liver risks.
What chronic low-grade inflammation is
Inflammation is your immune system’s response to injury or infection. A swollen ankle or a fever is acute inflammation: short, local and useful. It switches on, does the job, and switches off.
Chronic low-grade inflammation is different. It is a slow, body-wide simmer that does not switch off. You do not feel it. It shows up only as slightly raised blood markers such as C-reactive protein (CRP) or interleukin-6.
A widely cited 2019 review in Nature Medicine named the main drivers: physical inactivity, poor diet, psychological stress, infections and environmental pollutants. It linked persistent inflammation to cardiovascular disease, cancer, diabetes, chronic kidney disease, fatty liver and neurodegenerative disease.
Harvard Health makes an important caution, though: chronic inflammation has not been proven to cause these diseases. It often accompanies them. That is why “reducing inflammation” is best seen as one benefit of a healthy lifestyle, not a goal to chase with pills.
Can you measure it?
Your doctor can order a high-sensitivity CRP (hs-CRP) test. The American Heart Association and CDC grouped results for heart risk as follows:
| hs-CRP result | Heart-risk category | What it means for you |
|---|---|---|
| Below 1.0 mg/L | Low | Keep doing what you are doing |
| 1.0–3.0 mg/L | Intermediate | Worth reviewing waist, activity, diet and sleep |
| Above 3.0 mg/L | High | Discuss with your doctor alongside cholesterol and blood pressure |
| Above 10 mg/L | Not used for heart risk | Suggests an infection or other inflammatory condition; retest after about two weeks |
A cold, a hard workout or a minor injury can raise CRP temporarily, so a single reading is not definitive. Guidance suggests averaging two tests at least two weeks apart.
What the evidence says about diet
Mediterranean-style eating and PREDIMED
The best evidence comes from the Spanish PREDIMED trial, published in the New England Journal of Medicine. About 7,400 adults aged 55 to 80 at high cardiovascular risk were assigned to a Mediterranean diet supplemented with extra-virgin olive oil (about four tablespoons a day), a Mediterranean diet with 30 g of mixed nuts a day, or advice on a low-fat diet.
Over a median of 4.8 years, both Mediterranean groups had roughly 30% fewer major cardiovascular events (heart attack, stroke or cardiovascular death) than the low-fat group.
In fairness, the original 2013 paper was retracted and republished in 2018 after problems with randomisation at some sites were found. The reanalysis, which excluded or adjusted for those participants, reached essentially the same conclusion. Harvard’s Nutrition Source still describes PREDIMED as an important trial, while stressing that it is one part of a much larger body of evidence.
A PREDIMED subgroup of 164 participants also looked directly at inflammation. After 12 months, CRP and interleukin-6 fell in both Mediterranean groups compared with the low-fat group.
Weight loss is a big part of the story
Fat tissue, especially around the abdomen, releases inflammatory signals. A systematic review of 33 studies found that each kilogram of weight lost was associated with an average drop in CRP of about 0.13 mg/L. If you carry extra weight around your middle, losing some of it is one of the most reliable ways to lower inflammatory markers. Our guide to losing fat while keeping muscle after 35 shows you how.
Foods with solid evidence
Harvard Health’s list of foods linked to lower inflammation is not exotic: colourful fruits and vegetables, whole grains, nuts and seeds, pulses, fish, unsaturated fats, and herbs and spices. Here is how to build them into everyday Indian, Latin American and Mediterranean meals.
| Food group | Why it helps | Vegetarian Indian examples | Vegetarian Latin examples |
|---|---|---|---|
| Vegetables and leafy greens | Fibre, potassium and plant compounds (polyphenols) | Palak, methi, bhindi, lauki, cabbage sabzi | Spinach, chard, squash, nopales, tomato-onion hogao |
| Fruit, especially berries and deeply coloured fruit | Polyphenols and vitamin C | Jamun, guava, pomegranate, amla, papaya | Guava, mora, passion fruit, mango, papaya |
| Pulses and legumes | Fibre feeds gut bacteria; protein without saturated fat | Dal, rajma, chana, moong sprouts | Frijoles, lentejas, garbanzos |
| Whole grains | Fibre and slower glucose release | Whole-wheat roti, bajra, jowar, brown or hand-pounded rice | Whole corn arepas or tortillas, oats, quinoa |
| Nuts and seeds | Unsaturated fats, fibre, magnesium | Almonds, walnuts, flaxseed, peanuts | Peanuts, chia, pumpkin seeds |
| Healthy oils | Unsaturated fats and, for EVOO, polyphenols | Mustard, groundnut or olive oil in sensible amounts | Extra-virgin olive oil, avocado |
| Herbs and spices | Plant compounds; make vegetables taste good | Turmeric, ginger, garlic, cumin, coriander | Cilantro, garlic, oregano, chilli, cumin |
If you eat fish, oily fish such as salmon, sardines or mackerel twice a week adds omega-3 fats. Vegetarians can get the plant omega-3 ALA from flax, chia and walnuts; see our guide to omega-3 for men over 35 for how plant and marine sources compare.
What a day might look like
- Breakfast: Moong dal chilla with mint chutney and curd, or oats cooked with milk, walnuts and guava.
- Lunch: Rajma or chana with brown rice or two rotis, a large salad and cucumber raita. Or a bandeja-style plate rebuilt with beans, arepa, avocado and a big salad.
- Snack: A handful of almonds or roasted chana and a piece of fruit.
- Dinner: Palak paneer or tofu with a mixed vegetable sabzi and jowar roti, or lentil soup with vegetables, olive oil and whole-grain bread.
This also covers your protein needs if portions are adequate. See our guide to muscle-building foods for higher-protein vegetarian options.
What to cut back on
Diets heavy in the following are linked to worse heart and metabolic health, and they crowd out the foods above:
- Sugary drinks, including packaged juices and sweet chai or coffee drinks taken several times a day.
- Refined snacks and sweets: biscuits, namkeen, pastries, fried street snacks.
- Processed meats, if you eat meat.
- Deep-fried foods cooked in reused oil.
- Heavy drinking. Alcohol also disrupts sleep, which matters for recovery.
You do not need to eliminate these completely. Shifting the balance, so most meals are built on the foods in the table above, is what moves the needle.
What is hype
Cutting out nightshades
Tomatoes, potatoes, peppers and aubergine (brinjal) are often blamed for joint pain. The Arthritis Foundation has stated that research has found no evidence nightshades affect joints or worsen arthritis. Peppers are actually on its list of recommended vegetables. Cutting them out means losing nutrient-rich foods for no proven gain.
“All seed oils are inflammatory”
This claim is popular online. An American Heart Association science advisory reviewed omega-6 fats (found in many seed oils, nuts and seeds) and concluded they are not inherently pro-inflammatory; it recommended getting at least 5–10% of calories from them. The real problem is that seed oils are often used in deep-fried, ultra-processed foods. Cooking with them in normal amounts at home is a different matter.
High-dose turmeric and curcumin supplements
Turmeric in your dal is great. Concentrated curcumin pills are a different story. The US National Center for Complementary and Integrative Health says there is not enough evidence to conclude that turmeric or curcumin helps for any health purpose, though early results for knee osteoarthritis look positive.
More worrying, the NIH LiverTox database reports that turmeric has become the most common cause of herb-related liver injury in the US. Most cases involve high-absorption products, such as those combined with black pepper extract (piperine). Keep turmeric as a spice, not a pill, unless your doctor advises otherwise.
Juice cleanses, “detox” teas and alkaline water
None of these has good evidence for lowering inflammation in healthy people. Your liver and kidneys handle detoxification, and the money is better spent on vegetables and pulses.
Beyond food: the other inflammation levers
Diet works best alongside the rest of your lifestyle:
- Train regularly. Exercise causes a short inflammatory spike, but regular training is associated with lower resting inflammation over time, partly through fat loss and more muscle.
- Sleep seven or more hours. Poor sleep and chronic stress both feed the inflammatory cycle. See our guide to chronic stress and recovery.
- Do not smoke. Smoking drives inflammation and damages blood vessels.
- Look after your teeth and gums. Gum disease is a chronic infection, and infections are one of the recognised drivers of ongoing inflammation.
Safety note: Food changes are not a substitute for medical treatment of inflammatory conditions like rheumatoid arthritis, inflammatory bowel disease or gout. If you have persistent joint swelling, unexplained fatigue, weight loss or a high CRP, see a doctor. Talk to your doctor before taking turmeric, curcumin or fish-oil supplements, especially if you take blood thinners or other regular medication, have liver disease, or have an upcoming surgery. Stop any turmeric supplement and seek care if you notice dark urine, yellowing skin or eyes, nausea or unusual fatigue.
FAQ
How long does it take for diet to lower inflammation?
In the PREDIMED subgroup, changes in CRP and interleukin-6 were measured after 12 months. Weight loss also lowers CRP over time. Think in months, not days, and judge results by your waist, energy, blood pressure and lab markers together.
Is the Mediterranean diet suitable for vegetarians?
Yes. Its core is vegetables, fruit, legumes, whole grains, nuts and olive oil. Fish is optional. Indian vegetarian cooking built around dal, sabzi and whole grains already overlaps heavily with it.
Should I take an omega-3 supplement for inflammation?
If you rarely eat oily fish, ask your doctor whether one makes sense for you. Food first is the safer default.
Are dairy and wheat inflammatory?
For most people, no. Unless you have a diagnosed condition such as coeliac disease or a true dairy allergy, there is little evidence that whole grains or plain dairy like curd and yoghurt raise inflammation.
Is an hs-CRP test worth getting?
It can help your doctor assess heart risk alongside cholesterol and blood pressure, especially if you have a family history of heart disease. It is not a standalone health score.
