The results show that each 0.1 g per day or 0.1 percent energy per day increment of intake of n-3 polyunsaturated

A study published today in the British Medical Journal finds that people who followed health advice and ate certain omega-6 polyunsaturated

We have had 50 years of advice to substitute vegetable oils rich in polyunsaturated
fatty acids (PUFAs) for animal fats, rich in saturated fatty acids (SFAs).
