Is Winter-Dry Skin Driving You Crazy? Omega-7 Is The Answer!

Is Winter-Dry Skin Driving You Crazy? Omega-7 Is The Answer!

  Essential fatty acids (EFAs) are known to be beneficial for, amongst other things, skin health. And when it comes to EFAs, omega-3 and omega-6 are usually top of mind. You may even know about omega-9. But most people have never heard of omega-7, let alone know how good it is for the skin! Omega-7 (also called ‘palmitoleic acid’ in most scientific and clinical publications) is a rare but powerful monounsaturated fat (MUFA) that can be found in animal and plant sources, including macadamia nuts, cold-water fish and sea buckthorn seeds and berries. Sea buckthorn contains the highest concentration of this valuable fatty acid, up to 40% as compared to 17% in macadamia nuts. And whilst I’m going to touch on some of the numerous skin and health benefits, it is also known for its ability to support a healthy weight, as well as cardiovascular and gastro-intestinal health. Sea Buckthorn What makes sea buckthorn so intriguing is its unique composition of numerous nutrients, including omega-7. It’s a rich source of vitamins, minerals, amino acids, vitamin C, vitamin E, and carotenoids. Several sources have placed its combined bioactive substances at 190 for the berries, of which 106 of these are found in the oil alone. Although the fruits of sea buckthorn have been used as a remedy by traditional Tibetan and Mongolian medicine since ancient times, according to Oriental history, the Chinese were the first culture to utilise this berry as a drug. In 1977 this plant was formally listed in the Chinese pharmacopoeia by the Ministry of Public Health. Sea buckthorn’s pharmacological effects were recorded in some 1000-year old medicinal classics, such as the Yue Wang Yao and Sibu Yidian...
Omega 3 Improves Your Memory

Omega 3 Improves Your Memory

The journal PLOS One published an article on October 3, 2012 that reveals a benefit for supplementation with omega-3 fatty acids on working memory in young men and women. University of Pittsburgh researchers led by Rajesh Narendran of the Department of Radiology tested the effects of a supplement providing 930 milligrams eicosapentaenoic acid (EPA) and 750 milligrams docosahexaenoic acid (DHA) in 11 men and women between the ages of 18 and 25. Evaluation of working memory (via an “n-back test”), positron emission tomography (PET) imaging of the brain and tests for red blood cell fatty acid levels were conducted before and after the six month treatment period. Participants experienced an increase in plasma omega-3 fatty acid levels and improvement in working memory at the end of six months. “What was particularly interesting about the presupplementation n-back test was that it correlated positively with plasma omega-3,”observed Bita Moghaddam, whose lab conducted the research. “This means that the omega-3s they were getting from their diet already positively correlated with their working memory.” “Before seeing this data, I would have said it was impossible to move young healthy individuals above their cognitive best,” he remarked. “We found that members of this population can enhance their working memory performance even further, despite their already being at the top of their cognitive game.” Although the researchers had suggested increases in dopamine storage and a protein involved in decision making in a particular area of the brain as mechanisms supporting omega-3’s effect on cognitive function, PET scan results failed to support the hypothesis. “It is really interesting that diets enriched with omega-3 fatty acid can...
Nuts Contribute to Health of Brain And Body

Nuts Contribute to Health of Brain And Body

They’re among the earliest known foods. Archaeological evidence suggests that tree nuts were a major part of the human diet 780,000 years ago. Several varieties of nuts, along with the stone tools necessary to crack them open, have been found buried deep in bogs in the Middle East. Rich in energy and loaded with nutrients, nuts and, particularly, their cargo of omega-3 fatty acids are thought to have been essential to the evolution of the large, complex human brain. Researchers have long linked consumption of tree nuts, despite their significant fat content, to decreased risk of cardiovascular disease, obesity, diabetes, cancer and even Parkinson’s disease. Now comes evidence that they also improve cognition in general and specific ways. Most have high concentrations of vitamin E, the B vitamins (including folate), antioxidants, minerals such as magnesium, as well as omega-3 fats, all of which support myriad functions of the nervous system. Test Best Crack open some walnuts and improve your ability to think critically. Researchers find that eating a high concentration of walnuts (half a cup a day) boosts inferential verbal reasoning, especially the ability to distinguish true from false. An array of compounds in walnuts, including vitamin E, folate, melatonin and varied antioxidative polyphenols, protect the central nervous system and speed synaptic transmission. The significant supply of alpha-linolenic acid is essential for stability of neuronal membranes, through which all neuronal actions transpire. Memory Tracks Although not strictly tree nuts — they are the seed of a fruit related to plums — almonds may help save your memory. Mice rendered temporarily amnesiac were more apt to remember their way around...
