Because they produce oxidizing free radicals, several polyunsaturated fatty acids (PUFAs) -- including linoleic -- can kill cells (SN: 5/21/88, p.
Last year, Canadian researchers showed that three polyunsaturated fatty acids (PUFAs) -- including linoleic acid -- can be extremely efficient cancer-cell killers, largely owing to their ability to generate free radicals (highly reactive oxygen molecules) and toxic secondary products, including singlet oxygen (SN: 5/21/88, p.332).
The aim was to see if a combination of glucosamine sulfate (1500 mg/day) and the omega 3 polyunsaturated fatty acids EPA and DHA (group A), showed equivalence (noninferiority) or superiority as opposed to glucosamine sulfate alone (group B).The primary therapy evaluation was performed using the Western Ontario and McMaster Universities Arthrosis index (WOMAC) score.
Dr Lattka states that "the fetal contribution of long-chain polyunsaturated fatty acids of the omega-6 series is more relevant than expected; fetal DHA concentrations depend on maternal and fetal metabolism", and concludes that "the amount of DHA transmitted to the fetus through the placenta might be crucial for fetal development".
Patients received either omega 3 PUFAs (polyunsaturated fatty acids) in a capsule once daily (3494 patients) or placebo (3481 patients).

Depending on the nature of the structural chemistry of these chains, fatty acid can be categorized as saturated or unsaturated; the unsaturated fatty acids can be further classified into monounsaturated or polyunsaturated fatty acids.
Omega-3 Polyunsaturated Fatty Acid (PUFAs) ingredients market analyzed in this study include EPA and DHA omega-3s from marine oils such as fish oils, krill oils and squid oils; and algal oils.
The researchers examined the fatty acid profile of hempseed oil and found that polyunsaturated fatty acids (PUFAs) made up about 75 percent of the oil.
The researchers have concluded that there is no clear clinical evidence that the most common polyunsaturated fatty acid, omega-6 linoleic acid, can reduce people's risk of developing heart conditions.
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).
