People who eat fatty fish every day can get most of the omega-3 that they need. However, today most of the food is deprived of omega-3. Moreover, people eat less and less fish and more food rich in omega-6. The development of intensive agriculture and livestock has also led to the reduction of omega-3 in many foods such as green leafy vegetables, meats, eggs and even fish. Supplementation with fish oil is a convenient way to add omega-3 fatty acids into the daily diet.
