does anyone have any idea what kind of polyunsaturated fat is in wheat bran? omega-3, omega-6, omega-9..????? ...i need a source of omega-6's!
-
well it aint omega 9 as thats oleic acid which is a MUFA.
linseed oil, safflower are you cheapest sources of w-6
-
so you think that the naturally occuring polyunsaturated fats in my wheat bran are omega-6?
-
.i need a source of omega-6's!
What makes you think that?
-
What makes you think that?
because currently i believe i am getting ZERO omega 6 in my diet. ...i gt zero fat intake except for what is in my boneless skinless chicken breasts, whats in water packed tuna, and cla/omega 3 supplements.
-
any red meat in your diet?egg yolks? if so your getting some w-6. it would be very odd for you to be low on w-6
also as a side note id drop the cla, its bad all on fronts.

Why ???

nope zero egg yolks and very rarely do i ever eat red meat. maybe once every seven days.....not that i dont lie red meat. i love steak. i just dont get it that often.
-
Why ???
the main reason is that it causes insulin resistence.
i would just pick up some safflower oil, its a very cheap source.

Conjugated linoleic acid increases skeletal muscle ceramide content and decreases insulin sensitivity in overweight, non-diabetic humans.Thrush AB, Chabowski A, Heigenhauser GJ, McBride BW, Or-Rashid M, Dyck DJ.

The effect of conjugated linoleic acid (CLA), a popular weight-loss supplement, on insulin sensitivity in humans is controversial and has not been extensively studied. To date no studies have examined the effects of CLA supplementation on human skeletal muscle metabolism or lipid content. It is also unknown whether CLA accumulates in human skeletal muscle with supplementation. In the present study, 9 overweight, non-diabetic individuals received 4 g/d of mixed CLA isomers in the form of 1 g supplements, for 12 weeks. CLA isomers significantly increased in both plasma and skeletal muscle following supplementation. Skeletal muscle ceramide content was also significantly increased, although there was no consistent change in muscle diacylglycerol or triacylglycerol content. Insulin sensitivity was significantly decreased (p<or=0.05) following CLA supplementation, with a significant increase in glucose and insulin area under the curve during an oral glucose tolerance test (p<or=0.005). The protein content of PPARalpha, for which CLA is a potent ligand, was unchanged following supplementation. Accordingly, there was no change in markers of muscle oxidative capacity. In conclusion, mixed-isomer CLA supplementation in overweight non-diabetic humans results in the accumulation of CLA and ceramide in skeletal muscle, and decreases insulin sensitivity.
Conjugated linoleic acid intake in humans: a systematic review focusing on its effect on body composition, glucose, and lipid metabolism.Salas-Salvadó J, Márquez-Sandoval F, Bulló M.

Studies performed on different species show that the consumption of conjugated linoleic acid (CLA) leads to a loss of fat and total body weight, reduces the plasma concentrations of total and LDL cholesterol, and has an antiinflammatory effect. This article reviews the clinical trials on human beings that evaluate how mixtures of CLA isomers administered as supplements or CLA-enriched products can affect total body weight, body composition, plasma lipid profile, glycemia, insulinemia, insulin sensitivity, lipid oxidation, and inflammation. After analyzing the few studies published to date in reduced samples of healthy humans or patients with overweight, obesity, metabolic syndrome, or diabetes, we deduce that there is not enough evidence to show that conjugated linoleic acid has an effect on weight and body composition in humans. However, some of these studies have observed that the administration of various CLA isomers has adverse effects on lipid profile (it decreases HDL cholesterol concentration and increases Lp(a) circulating levels), glucose metabolism (glycemia, insulinemia or insulin sensitivity), lipid oxidation, inflammation, or endothelial function. Therefore, long-term randomized clinical trials, controlled with placebo, need to be made in large samples of patients to evaluate the efficacy and safety of CLA isomers before its indiscriminate use in human beings can be recommended.
there are more but most of the benefits are from rodent studies in vitro, which are the lowest form of evidence for a number of reasons. i would stay away from it as it has little benefit but has hinted at very negative side effects, especially for someone in fitness.
