These good fats have actually been shown to counter the effects of "bad" fats
in our blood and are important for maintaining good health of our hearts,
cells and nervous systems. In contrast to saturated and monounsaturated fatty
acids, PUFAs have at least two double bonds, a feature which affects crucially
their structural, physical and chemical properties.
There are two large families of PUFAs: omega-3, which has a fluidic effect on
the blood, and omega-6, involved in blood coagulation. A healthy body should
maintain a balance between the tendency of the blood to clot and its tendency
to flow. Both families can be metabolized to long-chain PUFAs (LC-PUFAs).
LC-PUFAs have been shown to have an important role in health and disease.
Today we not only consume more fat than is recommended in our current diet,
but the percentage of fat from the omega-6 family and other saturated fats is
quite high. This makes us more prone to coronary problems and thrombosis.
Diets rich in omega-3 fatty acids, contribute to reduce the risk of
cardiovascular disease. Pregnant women can also reduce the risk of premature
birth by taking omega-3.
To ensure the correct intake and balance of LC-PUFAs, dietary supplementation
is sometimes necessary. DSM Nutritional Products manufactures and sells under
the trade name ROPUFA® a range of PUFAs in the form of chemically unmodified
but highly refined vegetable and marine oils. Powder forms are used mainly in
dry goods such as bakery products and baby food. They are dispersible in cold
water, are exceptionally stable, and have a neutral taste and odour.
