How to Choose Foods That Support a Healthy Inflammatory Balance

Nutrition influences much more than body weight. Every meal affects metabolism, immune function, the gut microbiome, blood sugar regulation and the body's inflammatory processes.


While no single food can cause or cure chronic inflammation on its own, the dietary pattern you follow over months and years can influence whether your body maintains a healthy inflammatory balance or gradually shifts towards chronic low-grade inflammation.


The encouraging news is that food is one of the lifestyle factors we can improve every single day.


What are inflammatory foods?

Why chronic inflammation matters?

Inflammation itself is not the enemy.


Acute inflammation is a normal and essential part of the body's defence system. It helps us recover from infections, injuries and tissue damage.


The problem begins when inflammation becomes chronic and remains active even when there is no immediate threat. This persistent low-grade inflammation has been associated with an increased risk of many chronic conditions, including:

  • cardiovascular disease

  • type 2 diabetes

  • obesity and metabolic syndrome

  • certain cancers

  • non-alcoholic fatty liver disease


Diet is only one piece of the puzzle. Physical inactivity, excess body fat, chronic stress, poor sleep, smoking, excessive alcohol consumption and environmental factors also contribute to inflammation.


Your grocery choices matter

Not everything sold in a supermarket supports long-term health equally.


Research increasingly shows that diets high in ultra-processed foods (UPFs) are associated with a greater risk of obesity, type 2 diabetes, cardiovascular disease and premature mortality.


This does not mean that eating one processed food occasionally is harmful. The concern is when a large proportion of the diet consists of highly processed products that are typically high in added sugars, refined starches, unhealthy fats and salt while being low in fibre and essential nutrients.


Making healthier choices starts with understanding food labels.


Simple guidelines for healthier shopping


1. Choose foods with one ingredient whenever possible

One of the easiest ways to improve diet quality is to build meals around minimally processed foods.


Examples include:

  • vegetables

  • fruit and berries

  • plain fish

  • unseasoned meat

  • eggs

  • legumes

  • raw nuts

  • seeds

  • extra virgin olive oil

An avocado, for example, doesn't need an ingredient list.


This doesn't mean packaged foods should be avoided altogether. The goal is simply to make minimally processed foods the foundation of your diet.


2. Read the ingredient list

The ingredient list tells you far more than the front of the package.


A few useful rules include:

  • shorter ingredient lists are often easier to understand

  • ingredients are listed by weight, meaning the first ingredients are present in the greatest amounts

  • if sugar appears among the first ingredients, the product is likely high in added sugar


Some food additives have been studied for their potential effects on the gut microbiome or inflammatory markers. However, not all additives have been shown to negatively affect health, and their impact often depends on the amount consumed and the overall dietary pattern.


Ingredients worth limiting include:

  • partially hydrogenated oils (trans fats)

  • nitrites and nitrates in processed meats

  • heavily sweetened products (foods and drinks)

  • highly processed foods containing numerous artificial colours, flavours and additives


3. Check the sugar content

Nutrition labels include both naturally occurring and added sugars.


A useful guideline is:

4 grams of sugar = approximately 1 teaspoon of sugar.

For example, if a 370 g strawberry Greek yogurt contains 11 g of sugar per 100 g, the entire tub provides approximately 41 g of sugar—about 10 teaspoons.


Naturally occurring sugars, such as lactose in milk, are included in the total sugar value and are not the same as added sugars.


The gut microbiome: where food and inflammation meet

One of the most important ways nutrition influences inflammation is through the gut microbiome.


The trillions of microorganisms living in our digestive tract play a key role in immune function, digestion and metabolism.


A diet rich in fibre supports beneficial gut bacteria, which produce short-chain fatty acids such as butyrate. These compounds help maintain the intestinal barrier and support healthy immune regulation.


For this reason, improving inflammatory balance is not only about removing certain foods—it is equally about adding more foods that nourish the microbiome, like fibre rich foods, prebiotic and fermented foods.


Foods worth limiting


Added sugar and high-fructose corn syrup

Regular consumption of foods high in added sugars may contribute to blood sugar fluctuations, oxidative stress and metabolic dysfunction.


It is especially helpful to limit:


High-fructose corn syrup has also been associated with an increased risk of non-alcoholic fatty liver disease.


These concerns do not apply to whole fruit, which contains fibre, vitamins, minerals and beneficial plant compounds.



Trans fats

Industrial trans fats have consistently been associated with increased inflammation, unfavourable cholesterol levels and a higher risk of cardiovascular disease.

Although their use has declined in many countries, they may still be found in certain baked goods, fried foods and highly processed snacks.


Processed meats

Processed meats include products preserved by smoking, curing, salting or adding preservatives.

Examples include:

  • bacon

  • sausages

  • salami

  • ham

  • cured meats

The International Agency for Research on Cancer (IARC) classifies processed meat as carcinogenic to humans (Group 1) based on evidence linking regular consumption with an increased risk of colorectal cancer.


This does not mean occasional consumption is harmful, but choosing fish, legumes, eggs and minimally processed meats more often is a healthier long-term approach.


Refined carbohydrates

Refined grains have much of their fibre removed during processing.

Examples include:

  • white bread

  • white rice

  • pastries

  • cakes

  • many breakfast cereals


Replacing refined grains with whole grains helps increase fibre intake, supports gut health and promotes more stable blood sugar levels.


Foods that support a healthy inflammatory balance

Rather than looking for a single "superfood," focus on a dietary pattern rich in a wide variety of whole foods.


Aim to include plenty of:

Vegetables: broccoli, cabbage, Brussels sprouts, peppers, tomatoes, onions, garlic, beetroot, asparagus, sweet potatoes etc.

Fruit and berries: blueberries, strawberries, raspberries, blackberries, cranberries, citrus fruits, apples, pears, pomegranates etc.

Legumes: lentils, chickpeas, kidney beans, black beans, edamame etc.

Whole grains: oats, rye, barley, buckwheat, quinoa, brown rice etc.

Nuts and seeds: walnuts, almonds, pistachios, flaxseeds, chia seeds, hemp seeds and pumpkin seeds.

Healthy fats: extra virgin olive oil, avocado, nuts, seeds and oily fish. Learn more about healthy fats here.

Fish: salmon, trout, mackerel, sardines and herring, ideally two to three times per week.

Fermented dairy (if well tolerated): kefir, plain yogurt, Greek yogurt, cottage cheese and other fermented dairy products.

Herbs and spices such as turmeric, ginger, rosemary, oregano, cinnamon and garlic also contribute valuable phytochemicals to the diet.


Which dietary pattern has the strongest scientific evidence?

Among all dietary patterns studied, the Mediterranean diet has the strongest evidence for supporting healthy inflammatory balance.

It is characterised by:

  • abundant vegetables and fruit

  • legumes

  • whole grains

  • nuts and seeds

  • extra virgin olive oil as the primary fat

  • regular fish consumption

  • limited ultra-processed foods

  • fewer foods high in added sugar


Numerous studies have linked this dietary pattern with lower inflammatory markers, improved cardiovascular health and a reduced risk of type 2 diabetes.


Should everyone try an elimination diet?

Not necessarily.


However, if you regularly experience symptoms such as bloating, abdominal discomfort, reflux, diarrhoea, constipation or persistent skin issues, a structured elimination diet supervised by a qualified nutrition professional may help identify individual food sensitivities.


The goal is not to avoid foods indefinitely but to systematically reintroduce them and determine which foods, if any, trigger symptoms.


Key takeaways


Chronic low-grade inflammation is not caused by one food, nor can it be solved by adding a single "anti-inflammatory" food.


The strongest scientific evidence supports an overall healthy lifestyle that includes:

  • eating plenty of vegetables, fruit and berries

  • choosing whole grains and legumes regularly

  • consuming enough dietary fibre

  • including healthy fats, especially extra virgin olive oil

  • eating fish regularly

  • limiting ultra-processed foods and added sugars

  • staying physically active

  • getting enough quality sleep

  • managing stress

  • avoiding smoking

  • limiting alcohol intake


The most powerful changes come from your overall dietary pattern—not from eliminating one food or relying on one "superfood."
