The best sources of omega-3 fatty acids are:
- fatty fish, such as sardines, tuna, salmon, trout, mackerel, and herring
- ground flax and flaxseed oil
- sunflower, chia and hemp seeds
Repeatedly heating vegetable oils can decrease their antioxidant activity and increase free radical production, which may lead to poor health effects. Avoid overheating or burning of vegetable oils to keep their nutrient content.
