Erythrocyte membrane Fatty acids in multiple sclerosis patients and hot-nature dietary intervention with co-supplemented hemp-seed and evening-primrose oils.

“The risk of developing multiple sclerosis (MS) is associated with increased dietary intake of saturated fatty acids. For many years it has been suspected that this disease might be associated with an imbalance between unsaturated and saturated fatty acids.

We determined erythrocyte membrane fatty acids levels in Hot nature dietary intervention with co-supplemented hemp seed and evening primrose oils in multiple sclerosis patients…

We concluded that Hot-nature dietary intervention with co-supplemented hemp seed and evening primrose oils caused an increase PUFAs in MS patients and improvement in the erythrocyte membrane fatty acids composition. This could be an indication of restored plasma stores, and a reflection of disease severity reduction.”

Nutritional n-3 polyunsaturated fatty acids deficiency alters cannabinoid receptor signaling pathway in the brain and associated anxiety-like behavior in mice.

“N-3 polyunsaturated fatty acids (PUFAs) cannot be synthesized de novo in mammals and need to be provided by dietary means. In the brain, the main n-3 PUFA is docosahexaenoic acid (DHA), which is a key component of neuronal membranes. A low dietary level of DHA has been associated with increased risk of developing neuropsychiatric diseases; however, the mechanisms involved remain to be determined.

In this study, we found that long-term exposure to an n-3 deficient diet decreases the level of DHA in the brain and impairs the cannabinoid receptor signaling pathway in mood-controlling structures.

In n-3 deficient mice, the effect of the cannabinoid agonist WIN55,212-2 in an anxiety-like behavior test was abolished. In addition, the cannabinoid receptor signaling pathways were altered in the prefrontal cortex and the hypothalamus.

Consequently, our data suggest that behavioral changes linked to an n-3 dietary deficiency are due to an alteration in the endocannabinoid system in specific brain areas.”
