You may think that fat is bad for you. But there is one type, known as omega-3s – acids, that you should try very hard to eat more of. Found mainly in fish, omega-3s-a collective name for a group of polyunsaturated fats that include the unpronounceable eicosapentaenoic, docosahexaenoic and alpha-linolenic acids – play a key role in many vital body processes, from controlling blood clotting and blood pressure to reducing inflammation.
What’s it good for?

- eczema
- gout
- high blood pressure
- high cholesterol
- hives
- inflammatory bowel disease
- memory problems
- menstrual problems
- nail problems
- palpitations
- prostate problems

- wrinkles
Scientists first began looking at omega-3s when they noticed that the Inuit (Eskimos) seldom suffered from rheumatoid arthritis or heart disease, even though their diet was a veritable slick of fish, seal and whale oils. As it happens, all of these foods are high in omega-3s, so it didn’t take doctors long to realize that this class of fats is essential for good health.
Reduce your risk of heart disease
Heart disease is the number-one killer of British adults today. Most heart attacks occur when blood clots form in the arteries and block the flow of blood and oxygen to the heart. Study after study has shown that a diet rich in omega-3 fatty acids can reduce the risk of heart attack and also stroke. How do omega-3 s help?
- They lower blood pressure by inhibiting the production of prostaglandins, leukotrienes and thromboxane – substances in the body that cause blood vessels to narrow.
- They make cell-like structures in blood called platelets less likely to clump together and form clots.
- They reduce levels of triglycerides, blood fats related to cholesterol that have been linked to heart disease.
- They reduce inflammation in the arteries and also appear to strengthen the heart’s pumping rhythm.
