Hemp seed oil is considered to be the best nutritional oil for health because its essential fatty acid (EFA) profile is closest to that required by the human body.Essential fatty acids are termed as such because the body cannot manufacture them. Therefore, they must continually be replenished in the diet. EFAs are not stored or used for energy as are other fats. Instead, they are used as raw materials for cell structure and as precursors for the synthesis of many of the body’s vital biochemicals, including hormones; increases testosterone and prostaglandins ideal for boosting building growth of lean body mass both on men & women. Increases valuable insulin sensitivity is. Simply put, increased sensitivity promotes a much greater anabolic response to insulin and increases your fat-burning ability immensely, while insulin resistance leads to elevated fat storage, reduced hypertrophy and increased susceptibility to diseases such as diabetes. In fact studies show Omega 3s increase insulin sensitivity drastically, while its counterpart Omega 6s in higher dosage lead to insulin resistance so key to keep both at balance levels to prevent an imbalance of conversions of the fats, hence the reason why Hemp Seed’s EFA profile is one of the best sources.
The body absolutely requires fat in the diet in order to process such fat-soluble nutrients as vitamins A, D, E, and K as well as phytochemicals. Fat substitutes, like Olestra, Oatrim, and Simplesse for example, slide through the digestive system intact – which most people think is advantageous. But, fat substitutes compound a problem by not only being unable to absorb these nutrients into the body, but also they carry them directly into the feces for elimination.
What function is our Prostaglandins?
Prostaglandins, which regulate such cellular functions as communication, cholesterol production, and blood platelet aggregation. Since different prostaglandins often have opposite effects, they are needed by the body in a delicate balance obtained from a balanced intake of the two essential fatty acids (omega-6 and omega-3). For instance, the prostaglandins that key up the body’s response to stress are all made by omega-6 fatty acids while the ones that gear down the body’s response to stress are nearly all made by omega-3 fatty acids. Not surprisingly, stress-related diseases tend to respond to omega-3 supplementation.
Hemp Seed’s EFAs are precursors to the prostaglandin series (PGE 1, 2, and 3). PGE1 inhibits the production of cholesterol and dilates blood vessels and prevents the blood clotting of platelets in arteries. A study reported in 1992 indicated that a diet of hemp seed causes the serum levels of total cholesterol to drop dramatically. Blood pressure also decreases after several weeks of eating hemp seeds, apparently because of the steady supply of EFAs.
By weight, hemp seed is 30-35% oil, of which 80% consists of polyunsaturated EFAs, specifically the two most important ones – linoleic acid (LA – omega-6 at 60%) and linolenic acid (LNA or ALA – omega-3 at 20%). These are the parent compounds which build longer-chain fatty acids. LNA then converts to DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) – two of the most critically needed forms of EFA and LA converts to AA (arachidonic acid), which has opposite effects of those from DHA. An excess of AA – the result of too much omega-6 – ultimately leads to such health problems as inflammation and, more importantly, increases blood clotting, which can cause heart attack, stroke, or embolism. In the last 40 years, the American diet has become loaded with excess omega-6 from corn and soybean oil, margarine, and similar processed fats. At the same time, Americans eat 500 mg of omega-3 per day, much less than they need. Consequently, instead of the 3:1 ratio they should be getting, most people consuming the western-type diet, end up with a ratio of 50:1.
Other fatty acids in hemp seed oil include: Palmitoleic acid, Heptadecanoic acid, Arachiditic acid, Eicosenoic acid, Behenic acid, Erucic acid, Lignoceric acid, and Nervonic acid; but it also contains several higher fatty acids. It is one of the only food oils to contain the direct metabolites of LA and LNA. Most notable are GLA (gamma linolenic acid from LA) and SDA (stearidonic acid from LNA), which serve as intermediaries in the formation of longer-chain fatty acids and vital hormone-like prostaglandins in the body. Because of this, hemp seed oil is able to circumvent the impaired EFA metabolism and physical compromise that can result from genetic factors, intake of other fats, aging, and lifestyle patterns.
Symptoms of an LNA (omega-3) deficiency include: dry skin, growth retardation, weakness, impaired learning ability, poor motor coordination, behavioral changes, impaired vision, high blood pressure, sticky platelets, edema, mental deterioration, low metabolic rate, and immune dysfunction (see more under Hemp as Medicine)
Although LA (omega-6) is present in our bodies in much greater quantities and because the western diet has an over-abundance, deficiencies are rare but can happen. Symptoms of an LA deficiency include: skin eruptions (acne and eczema-like), loss of hair, poor blood circulation, behavioral disturbances, liver and kidney degeneration, gallbladder problems, prostatitis, muscle tremors, abnormal water loss through the skin (sweating profusely), susceptibility to infections, im
These deficiency symptoms are all reversible with adequate intakes of EFAs from Hempseed Oil. But if ignored for a long time, health problems can develop into more serious degenerative conditions, paired wound healing, male sterility, miscarriage, arthritis, cardiovascular disease, and growth retardation.
Low Fat Diets:
Reductions of essential fatty acids (EFAs) in ultra-low fat and fat-free diets actually cause people to feel hungrier than they did before going on such a diet. It can also begin the process of dangerous EFA deficiency which causes people to binge on high-calorie foods to compensate for feeling unsatisfied.
Fat-free diets have been correlated with violent, short tempers in human and animal studies. Such diets can also cause high cholesterol levels because the body produces excess cholesterol in an attempt to make up for the lack of EFAs.
Hempseed oil, therefore, may be thought of as a “diet” oil, because it contributes fewer calories than most other oils or fats and because it is so rich in EFAs, vital for cell metabolism. Experts say getting more than 12-15% of calories from EFAs will actually aid in burning off excess fat and thereby contributing to weight loss & insulin management.
Suggested Hempseed Oil Dosage
One tablespoon of hempseed oil or 1 ounce of shelled hempseed supplies roughly 6.6 grams of omega-6 and 2.2 grams of omega-3 – just the amounts needed for a 2000-calorie diet. This is a suitable amount even for vegetarians and takes into account the conversion ration of 1% ALA to DHA, the currently accepted conversion rate for plant sources of omega-3.
Hempseed oil is best stored in the fridge or best in a freezer. It will stay fluid and does not need to be defrosted. One to 3 tablespoons is the suggested daily intake for adults; athletes up to 3 tbsp; children can take half that amount; and breast-fed babies obtain its benefits through the mother’s milk.
