(linoleic + linolenic acid) content changed across environments.

Most people in the UK and elsewhere, for a variety of genetic, lifestyle and diet-related reasons, are unable to carry out this transformation at a rate high enough to meet their needs for long chain omega-3 polyunsaturates
In test animals, diets high in polyunsaturates
from vegetable oils inhibit the ability to learn, especially under conditions of stress; are toxic to the liver; compromise the integrity of the immune system; depress the mental and physical growth of infants; increase levels of uric acid in the blood; cause abnormal fatty acid profiles in the adipose tissues: have been linked to mental decline and chromosomal damage and accelerate aging.
A new study suggests that frying or cooking food in polyunsaturates
converts the oils into a highly toxic substances called aldehydes, which can cause heart disease and cancer.
They say that although their conclusion agrees with findings of some experts, it conflicts with others that have suggested that the highly touted polyunsaturates
may reduce good cholesterol.
' effects aren't all beneficial: they reduce bot"good"bad" cholesterol.
Monounsaturates are neutral for heart disease, and polyunsaturates
lower blood cholesterol levels.
Grundy decided to conduct a study to see how well a diet rich in monounsaturated fatty acids compared with a diet high in polyunsaturates
or other types of fats.
Those present were able to attend sessions with titles: Biosynthesis and supply of polyunsaturated fatty acids; Biomarkers of essential fatty acid intake; Biological functions of docosahexaenoic acid; Effect of omega-3 deficiency in animals and man; Essential fatty acids and pregnancy; Polyunsaturated fatty acids in infant nutrition; Alcohol and essential fatty acids; Dietary fatty acids and coronary heart disease - polyunsaturates
; Dietary fatty acids and coronary heart disease - monounsaturates; Dietary lipids and thrombosis; Polyunsaturated fatty acids and hypertension; Polyunsaturated fatty acids and inflammation; Clinical effects of omega-6 and omega-3 polyunsaturated fatty acids; Essential fatty acids and diabetes; Essential fatty acids in the skin; and Hot topics.
However, that risk increased by almost 70 percent for each 5 grams of polyunsaturates
downed per day.
As omega-3 dropped from 50 percent of polyunsaturates
to some 12 percent, bone formation also fell--by about 20 percent.
