The fiber content in hemp seeds can aid in digestive health. Soluble fiber from these seeds can help to regulate digestion, potentially alleviating constipation and diarrhea. It is also conducive to a healthy gut microbiome, which is vital for proper immune system function and overall well-being.
Skin Health
For skin health, hemp seeds offer both omega-3 and omega-6 fatty acids in a balanced ratio, which can be beneficial in managing skin disorders such as eczema. These essential fatty acids help to reduce inflammation in the body including the skin, supporting the maintenance of healthy cell membranes.
Hormonal Balance
Hemp seeds may also contribute to hormonal balance. GLA, found in hemp seeds, has been eyed for its role in regulating hormone levels and might provide relief from symptoms associated with PMS and menopause. Regular consumption of GLA-rich foods like hemp seeds could support overall hormonal health.
Incorporating Hemp Seeds into Your Diet
Hemp seeds offer a versatile addition to numerous recipes due to their high nutritional value and delicate, nutty flavor. They can easily be integrated into daily meals and snacks for a healthful boost.
Hemp Seeds in Recipes
Hemp hearts, the shelled hemp seeds, can be sprinkled over salad for a crunchy texture or added to cereal for a morning nutrient kick. Their nutty taste complements granola and muffins, and when mixed into batter, they lend a pleasant crunch to pancakes. For a fiber-rich alternative, one can substitute chia seeds with hemp seeds in recipes.
Salads: Toss a tablespoon into green or fruit salads.
Cereals: Sprinkle over hot oatmeal or mix with cold cereals.
Baked Goods: Add hemp seeds to muffin or pancake mixtures.
Hemp Seed Oil Uses
Hemp seed oil, extracted from the seeds, is best used as a finishing oil rather than for cooking, due to its low smoke point. Drizzled over a completed dish, it infuses a subtle, nutty flavor. Hemp seed oil can enhance the taste of salads and be used as a base for dressings.
Salad Dressing: Blend with vinegar and spices for a unique dressing.
Dips: Stir into hummus or yogurt-based dips for an extra dose of healthy fats.
Hemp Milk and Smoothies
Hemp milk, made from blended hemp seeds and water, serves as a nutritious dairy alternative and can be used in the same manner as traditional milk. For a quick, nutritious drink, hemp seeds can be added directly to smoothies for added protein and texture, blending smoothly with both fruits and vegetables.
Smoothie Addition: Incorporate into any smoothie recipe for a protein boost.
Milk Substitute: Use hemp milk in cereals, coffee, or in baking as a dairy replacement.
Cannabis Sativa and THC
Cannabis sativa is a plant species that encompasses both hemp and marijuana, varieties distinguished predominantly by their tetrahydrocannabinol (THC) content.
Hemp vs. Marijuana
Hemp and marijuana both originate from the species Cannabis sativa but differ significantly in their THC concentrations. Hemp is cultivated to have a THC content of 0.3% or less by dry weight, making it non-psychoactive. This is in contrast to marijuana, which is bred for higher THC levels and psychoactive effects. The cultivation of hemp is regulated with strict THC limits— for example, in Canada, hemp seeds must contain less than 10 µg/g of THC.
Psychoactive Properties
THC, short for delta-9-tetrahydrocannabinol, is the primary psychoactive compound found in cannabis plants. Its concentration in a plant dictates the psychoactive potential. Marijuana contains high levels of THC, leading to the 'high' users experience. Conversely, the THC levels in hemp are so low that they do not produce psychoactive effects, thereby making hemp seeds and derived products safe to consume without the risk of intoxication.
Considerations and Side Effects
When adding raw hemp seeds to one's diet, it's important to consider both their benefits and the possible side effects. While generally considered safe for most people, there are certain factors like possible medication interactions and allergic reactions to keep in mind.
Potential Interactions with Medications
Raw hemp seeds contain arginine, an amino acid associated with blood pressure regulation. While beneficial for cardiovascular health, arginine could potentially alter blood pressure. This is especially relevant for individuals on medications for hypertension or those with blood pressure concerns. Additionally, individuals with Type 2 diabetes should consult their healthcare provider due to the potential blood sugar level alterations.
Allergic Reactions and Digestive Issues
Though rare, some people may experience allergic reactions to hemp seeds. Symptoms could range from mild to severe and include skin rashes or gastrointestinal distress. In terms of digestive issues, hemp seeds are high in fat, which, when consumed in large quantities, may lead to diarrhea or gas. Such side effects are typically mild and can be mitigated by moderating intake.
Moreover, while they contain beneficial nutrients, individuals with conditions like acne, PMS, menopause, or premenstrual syndrome should monitor any changes in their symptoms when consuming hemp seeds, as dietary changes can sometimes influence such conditions.
