TEXT 2: OMEGA-3

1 The difference between oily fish and white fish is like that between long distance runners and lazy people, and you may be surprised

2 to learn that the fatty fish are the athletes here. Also known as "pelagic", from the Greek word for ocean, because they are always on

3 the move, sardines, tuna and their kind spend their entire lives swimming in the direction of the next meal. Such an exhausting existence

4 requires a ready source of fuel, and the energy these fish need is saturated throughout their body tissues in the form of oil, ready to

5 burn.

6 Studies on the benefits of this oil to human health started in the 70s. Then, Danish researchers studying Inuit populations in the

7 Arctic regions noticed that, despite eating a diet high in saturated fat, there was low incidence of heart disease. They claimed this might

8 be thanks to a fatty acid, omega-3, which is found almost exclusively in oily fish. It wasn't long before a multibillion-dollar industry

9 producing supplement pills was born.

10 Fish oil, we now know, is rich in the omega-3 fatty acids. They are a vital part of our cells and also play an important role in the

11 production of hormones that control the thickness of the blood and the movement of artery walls. Fatty acids also regulate inflammation

12 throughout the body. Yet, unlike other kinds of fat, our bodies cannot produce them and must take them from food. Some of these

13 omega-3 acids are found in several vegetable sources such as nuts, seeds and leafy vegetables, while others are present in some

14 animal fats, mainly in fish.
