We're all getting the message that fish oils can protect us against heart disease - but how much do we need to be taking each day?
A daily dose of 200 mg of omega-3 fatty acid is enough to prevent heart disease, diabetes and ageing in a healthy male, researchers have found after researching the effects on 12 volunteers aged between 53 and 65. The men consumed a range of quantities of omega-3, from 200 mg right up to 1600 mg, every day, and discovered that the lowest amount was, in fact, optimum.
You can get omega-3 from oils, supplements and by eating fatty fish, such as salmon and tuna.
