WBC NUTRITION COMMITTEE: Hemp seeds
By Dr. Phillip Goglia
Hemp seeds, which are technically a nut, are one of the highest sources of plant protein. They also contain both Omega-3 and the less common Omega-6 fatty acids.
Fun Fact: Hemp seeds come from the same plant as marijuana but do not contain the drug.
Technically a nut, hemp seeds are very nutritious. They have a mild, nutty flavor and are often referred to as hemp hearts.
Hemp seeds contain over 30% fat. They are exceptionally rich in two essential fatty acids, linoleic acid (omega-6) and alpha-linolenic acid (omega-3).
They also contain gamma-linolenic acid, which has been linked with several health benefits (1).
Hemp seeds are a great protein source, as more than 25% of their total calories are from high-quality protein.
Hemp s Hemp seeds are a good source of polyunsaturated and essential fatty acids. They have about a 3:1 ratio of omega-6 to omega-3, which is considered in the optimal range.
Studies have shown that giving hemp seed oil to people with eczema may improve blood levels of essential fatty acids.
It may also relieve dry skin, improve itchiness and reduce the need for skin medication
Hemp seeds can be consumed raw, cooked or roasted. Hemp seed oil is also very healthy, and has been used as a food/medicine in China for at least 3,000 years (1).
Interestingly, eating hemp seeds may reduce the risk of heart disease via several mechanisms.
Nitric oxide is a gas molecule that makes the blood vessels dilate and relax, leading to lowered blood pressure and a reduced risk of heart disease (5).
Additionally, animal studies have shown that hemp seeds or hemp seed oil may reduce blood pressure, decrease the risk of blood clot formation and help the heart recover after a heart attack
They are considered a complete protein source, which means that they provide all the essential amino acids. Essential amino acids are not produced in the body and need to be gotten from the diet.
Complete protein sources are very rare in the plant kingdom, as plants often lack the amino acid lysine. Quinoa is another example of a complete, plant-based protein source.
Hemp seeds contain significant amounts of the amino acids methionine and cysteine, as well as very high levels of arginine and glutamic acid (18).
The digestibility of hemp protein is also very good — better than protein from many grains, nuts
Up to 80% of women of reproductive age may suffer from physical or emotional symptoms caused by premenstrual syndrome (PMS) (20).
In a study of women with PMS, taking one gram of essential fatty acids (including 210 mg of GLA) per day resulted in a significant decrease in symptoms (22).
Other studies have shown that primrose oil, which is rich in GLA, may be highly effective in reducing symptoms for women who have failed other PMS therapies.
It decreased breast pain and tenderness, depression, irritability and fluid retention associated with PMS (25).
Because hemp seeds are high in GLA, several studies have indicated that hemp seeds may also help reduce the symptoms of menopause.
Exactly how this works is unknown, but it has been suggested that the GLA in hemp seeds may help to regulate the hormone imbalances and inflammation associated with menopause
Although hemp seeds have not been popular until recently, they are an old staple food and people are now realizing their excellent nutritional value.
They are very rich in healthy fats, high-quality protein and several minerals.
However, hemp seed shells may contain trace amounts of THC (< 0.3%), the active compound in marijuana. People who have been addicted to cannabis may want to avoid consuming hemp or hemp seeds in any form.
Overall, hemp seeds are incredibly healthy. They might just be one of the few superfoods that are actually worthy of their reputation.
