What is Inflammation and How Does Food Affect It
Inflammation is the immune system's response to injury, infection, or threat. In its acute form, it is essential: the redness, swelling, and heat around a wound are inflammation doing its job. The problem is chronic low-grade inflammation, a persistent, low-level activation of the immune system that has no clear trigger, produces no obvious symptoms in the short term, and over years and decades drives some of the most significant health conditions affecting Indians today.
What chronic inflammation drives
Type 2 diabetes, cardiovascular disease, fatty liver disease, certain cancers, Alzheimer's disease, depression, and autoimmune conditions all have chronic inflammation as a significant underlying driver. The connection between diet and these conditions runs substantially through the inflammation pathway.
What drives chronic inflammation in the Indian diet
Ultra-processed foods are the primary dietary driver. Refined vegetable oils high in omega-6 fatty acids, particularly palmolein and sunflower oil at high temperatures, generate oxidised lipids that promote inflammatory signalling. Refined carbohydrates and excess sugar elevate blood glucose and produce advanced glycation end products that trigger inflammatory responses. Inadequate fibre intake reduces butyrate production in the gut, which normally helps regulate the immune response.
Chronic stress, insufficient sleep, and physical inactivity compound dietary inflammation drivers. The urban Indian lifestyle stacks all of these simultaneously.
Foods that reduce inflammation
The Indian kitchen contains some of the most potent anti-inflammatory foods documented by nutrition science. Turmeric contains curcumin, which modulates multiple inflammatory pathways. Ginger contains gingerols and shogaols with well-documented anti-inflammatory effects. Garlic and onion provide quercetin and other flavonoids. Dark leafy greens provide Vitamin K and antioxidants. Whole legumes and millets provide fibre that feeds anti-inflammatory gut bacteria.
Omega-3 fatty acids, found in flaxseeds, walnuts, and fatty fish, directly counter the pro-inflammatory effects of excess omega-6 intake.
The practical framework
Reduce refined oils and ultra-processed food. Cook with turmeric and ginger as a daily habit rather than an occasional addition. Eat a diverse range of plant foods to support the gut bacteria that regulate inflammation. Include flaxseeds or walnuts regularly for omega-3s. These are not dramatic interventions. They are cumulative habits that, maintained consistently, meaningfully reduce the inflammatory load the body carries.
