Inflammation is your body's natural alarm system. When you get a cut or an infection, inflammation helps you heal. But when inflammation stays turned on all the time — often because of what you eat — it starts damaging your blood vessels and contributing to heart disease, diabetes, and other chronic conditions.
Ultra-processed foods — chips, fast food, packaged snacks — are major triggers. A study of over 105,000 people found that eating more ultra-processed foods was linked to a 12% higher risk of heart disease for every 10% increase in how much ultra-processed food made up their diet.
On the other side, certain foods actively fight inflammation. Omega-3 fatty acids — found in salmon, mackerel, and flaxseeds — directly reduce inflammatory chemicals in your body. Colorful vegetables and fruits contain compounds that work in similar ways. Fiber from whole grains and legumes feeds helpful gut bacteria that produce compounds that calm inflammation throughout your body.
One of the most studied anti-inflammatory diets is the Mediterranean diet. A landmark study found it reduced the risk of major heart events — like heart attacks and strokes — by 30% in high-risk patients.
Eating more whole foods and less ultra-processed food is one of the most powerful tools you have for protecting your heart.
