Things worth knowing about "Anti-inflammatory Diet"
An anti-inflammatory diet reduces chronic inflammation in the body through targeted food choices. It may lower the risk of many chronic diseases.
What is an Anti-inflammatory Diet?
An anti-inflammatory diet is an eating pattern designed to reduce or prevent chronic inflammation in the body. While acute inflammation is a necessary immune response, chronic low-grade inflammation is considered a contributing factor to many serious diseases, including cardiovascular disease, type 2 diabetes, rheumatoid arthritis, certain cancers, and neurodegenerative disorders.
By consciously choosing certain foods and avoiding others, it is possible to positively influence the body's inflammatory response. This dietary approach is based on evidence from nutritional medicine and immunology.
Mechanism of Action
Certain food components can inhibit pro-inflammatory signaling pathways in the body. Key mechanisms include:
- Omega-3 fatty acids: They promote the production of anti-inflammatory mediators (resolvins, protectins) and inhibit pro-inflammatory prostaglandin synthesis.
- Polyphenols and antioxidants: They neutralize free radicals and inhibit pro-inflammatory transcription factors such as NF-κB.
- Dietary fiber: Promotes a healthy gut microbiome, which plays a central role in regulating immune responses.
- Secondary plant compounds (e.g., curcumin, quercetin, resveratrol): Directly inhibit pro-inflammatory enzymes such as COX-2 and LOX.
Recommended Foods
An anti-inflammatory diet emphasizes the following food groups:
- Fatty fish (salmon, mackerel, herring, sardines): Rich in omega-3 fatty acids EPA and DHA.
- Vegetables and fruits: Especially berries, broccoli, spinach, kale, and tomatoes, which provide antioxidants and polyphenols.
- Nuts and seeds: Walnuts, flaxseeds, and chia seeds are good sources of plant-based omega-3 fatty acids (ALA).
- Olive oil: Contains oleocanthal, which has anti-inflammatory properties similar to ibuprofen.
- Legumes (lentils, beans, chickpeas): Provide dietary fiber and plant-based protein.
- Whole grains: Contain fiber that supports gut microbiome health.
- Herbs and spices: Turmeric, ginger, garlic, and cinnamon have well-documented anti-inflammatory properties.
- Green tea: Rich in catechins with antioxidant and anti-inflammatory effects.
Foods to Avoid
Equally important as consuming anti-inflammatory foods is limiting pro-inflammatory ones:
- Sugar and sugary beverages: Promote the release of pro-inflammatory cytokines.
- Refined carbohydrates (white bread, white flour products): Cause blood sugar spikes that favor inflammation.
- Trans fatty acids (found in processed foods and fast food): Inhibit anti-inflammatory enzymes.
- Omega-6-rich vegetable oils (sunflower oil, corn oil): A high omega-6 to omega-3 ratio promotes inflammation.
- Alcohol: Increases intestinal permeability and promotes systemic inflammation.
- Red and processed meat: Contains arachidonic acid and other compounds that may promote inflammation.
Dietary Patterns with Anti-inflammatory Effects
Certain overall dietary patterns are particularly well-supported by scientific evidence for their anti-inflammatory effects:
- Mediterranean diet: Rich in olive oil, fish, vegetables, legumes, and nuts. It is the most extensively studied anti-inflammatory dietary pattern.
- MIND diet: A combination of the Mediterranean and DASH diets, focused on brain-healthy foods.
- Plant-based diet: High in dietary fiber, phytonutrients, and antioxidants.
Scientific Evidence
Numerous studies support the benefits of an anti-inflammatory diet. Biomarkers such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) are measurably reduced by such a dietary approach. Evidence is especially strong for:
- Cardiovascular disease
- Rheumatoid arthritis
- Metabolic syndrome
- Inflammatory bowel disease
- Neurodegenerative diseases (e.g., Alzheimer's disease)
Practical Tips
An anti-inflammatory diet does not need to be a strict regimen. The following everyday tips can help you get started:
- Eat at least 5 portions of vegetables and fruit per day.
- Include fatty fish in your diet twice a week.
- Use olive oil as your primary fat source.
- Largely avoid ultra-processed foods and fast food.
- Regularly use herbs such as turmeric and ginger in cooking.
- Drink plenty of water and reduce alcohol consumption.
