6 Health Benefits of Hemp Seeds: Backed up by Science.
1. Hemp Seeds Are Incredibly Nutritious
Technically a nut, hemp seeds are very nutritious. They have a mild, nutty flavour 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
Hemp seeds are a great protein source, as more than 25% of their total calories are from high-quality protein.
That is considerably more than similar foods like chia and flaxseeds which provide about 16–18%.
Hemp seeds are also a great source of vitamin E and minerals such as phosphorus, potassium, sodium, magnesium, sulphur, calcium, iron and zinc
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.
2. Hemp Seeds May Reduce the Risk of Heart Disease
Heart disease is the number one killer worldwide
Interestingly, eating hemp seeds may reduce the risk of heart disease via several mechanisms.
They contain high amounts of the amino acid arginine, which is used to produce nitric oxide in the body.
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.
In one large study of more than 13,000 people, increased arginine intake was linked with decreased levels of C-reactive protein (CRP). CRP is an inflammatory marker linked with heart disease
The gamma-linolenic acid found in hemp seeds has also been linked with reduced inflammation, which may decrease the risk of diseases like heart disease.
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
3. Hemp Seeds and Oil May Benefit Skin Disorders
Fatty acids may affect immune responses in the body.
This may have something to do with the balance of omega 6 and omega 3 acids.
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.
4. Hemp Seeds Are a Great Source of Plant-Based Protein
About 25% of calories in hemp seeds come from protein, which is relatively high.
In fact, by weight, hemp seeds provide amounts of protein similar to beef and lamb. 30 grams of hemp seeds, or 2–3 tablespoons, provide about 11 grams of protein.
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 an 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
The digestibility of hemp protein is also very good, better than protein from many grains, nuts and legu.mes
5. Hemp Seeds May Reduce Symptoms of PMS and Menopause
Up to 80% of women of reproductive age may suffer from physical or emotional symptoms caused by premenstrual syndrome (PMS)
These symptoms are very likely caused by sensitivity to the hormone prolactin
Gamma-linolenic acid (GLA), found in hemp seeds, produces prostaglandin E1, which reduces the effects of prolactin
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
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
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
6. Whole Hemp Seeds May Aid Digestion
Fibre is an essential part of the diet and is linked with better digestive health
Whole hemp seeds are a good source of both soluble (20%) and insoluble (80%) fibre.
Soluble fibre forms a gel-like substance in the gut. It is a valuable
source of nutrients for the beneficial digestive bacteria, and may also reduce spikes in blood sugar and regulate cholesterol levels
Insoluble fibre adds bulk to fecal matter and may help food and waste pass through the gut. Consuming insoluble fibre has also been linked with a reduced risk of diabetes
However, de-hulled or shelled hemp seeds (also known as hemp hearts) contain very little fiber, because the fiber-rich shell has been removed.
The Message is:
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.
