Hemp: A Historical Overview and its Reemergence in the Health Scene

Hemp, botanically known as Cannabis Sativa L., has a rich history of utility that dates back to ancient civilisations. Archaeological evidence from Asia suggests that hemp has been used for medicinal, nutritional, and industrial purposes for over 10,000 years. Despite its broad range of applications, misconceptions, and regulatory challenges led to a decline in hemp cultivation and use, particularly during the 20th century.

Fast forward to the 21st century, hemp is making a solid reemergence in the health and wellness scene. The resurgence can be attributed to a greater understanding of its nutritional profile and changing regulations that distinguish hemp from its psychoactive cousin, marijuana. Both derive from the Cannabis plant family but have stark differences in their chemical compositions; hemp contains less than 0.3% of THC (tetrahydrocannabinol), the psychoactive compound found in high amounts in marijuana.

The shift in perspective has paved the way for exploring hemp's nutritional prowess, particularly the seeds, which are a rich source of protein. Modern dietary science underscores the importance of hemp as a viable source of plant-based protein, which is gaining popularity for both health and environmental reasons.

Understanding the Nutritional Composition of Hemp Seeds

Hemp seeds, often called "hemp hearts," are a nutritional powerhouse. They are an excellent source of protein, healthy fats, fiber, and various essential minerals and vitamins. One ounce (about two tablespoons) of hemp seeds contains approximately 9 grams of protein, comparable to the protein content in similar amounts of chia seeds and flaxseeds.

A unique characteristic of hemp protein is its completeness in terms of the essential amino acids. Amino acids are the building blocks of proteins, and the human body requires 20 different amino acids to function optimally. Nine are "essential," meaning they must be obtained from the diet because the body cannot produce them. Hemp seeds contain all nine essential amino acids, making them a "complete" source of protein, which is rare among plant-based proteins.

Additionally, hemp seeds are rich in healthy fats, primarily polyunsaturated fats, including Omega-3 and Omega-6 fatty acids. They also contain a significant amount of fiber, which aids in digestion, and an array of essential minerals such as phosphorus, potassium, sodium, magnesium, sulfur, calcium, iron, and zinc.

Protein Quality in Hemp: Amino Acid Profile and Digestibility

The quality of a protein source is determined by its amino acid profile and digestibility. As mentioned, hemp seeds contain all nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. This profile is comparable to other high-quality protein sources such as meat, milk, eggs, and soy.

The digestibility of hemp protein is also high, meaning the body can easily break down and absorb the protein. It is estimated that about 91-98% of the protein in ground hemp seeds can be digested. This high digestibility can be attributed to the types of proteins in hemp; about two-thirds is edestin and one-third albumin, both of which are easily digestible proteins.

Comparing Hemp Protein to Other Plant-based Proteins: A Nutrient Analysis

In comparison to other plant-based proteins, hemp stands out in several ways. While many plant proteins lack one or more essential amino acids, hemp is a complete protein. For example, while pea protein is rich in lysine, it falls short on methionine. Rice protein, on the other hand, is low in lysine. Hemp protein doesn't have these shortcomings.

Compared to soy, another complete plant protein, hemp has the advantage of being hypoallergenic. Soy is a common allergen and contains compounds called phytates, which can inhibit the absorption of minerals. On the other hand, hemp doesn't have these issues, making it an excellent protein source for a wide range of individuals.

Nutrient-wise, hemp seeds contain more fiber than most other seeds. This high fiber content can help improve gut health, control blood sugar, and manage weight. Additionally, hemp seeds' omega-3 to omega-6 ratio is considered optimal for human health, an attribute not common in many other plant-based protein sources.

Health Benefits of Hemp Seeds: Beyond the Protein Content

While hemp's protein content is impressive, its health benefits extend far beyond protein. The rich nutrient profile of hemp seeds supports various aspects of health, including heart health, skin health, and immune function.

Research has found that the consumption of hemp seeds may improve heart health due to the high amounts of the amino acid arginine, which produces nitric oxide in the body. Nitric oxide is a gas molecule that dilates blood vessels and reduces blood pressure, promoting heart health.

Hemp seeds are also a great source of gamma-linolenic acid (GLA), an omega-6 fatty acid with anti-inflammatory properties. Studies have shown that GLA can help reduce symptoms like ADHD, heart disease, and skin conditions such as eczema and psoriasis.

Furthermore, hemp seeds contain various vitamins and minerals, including Vitamin E, potassium, and magnesium, crucial in multiple physiological functions.

Hemp Seeds and Heart Health: The Role of Omega-3 and Omega-6 Fatty Acids

Hemp seeds have a desirable balance of omega-3 to omega-6 fatty acids, with a ratio of approximately 3:1, which is considered optimal for human health. These polyunsaturated fats are crucial for the body as they aid in reducing inflammation and promoting heart health.

Omega-3 fatty acids are known for their role in reducing inflammation and protecting against heart disease and stroke. On the other hand, omega-6 fatty acids are necessary for skin and hair growth, bone health, and regulating metabolism.

However, it's crucial to maintain a balance between these two fatty acids. Modern diets often contain excessive omega-6 and insufficient omega-3, a discrepancy linked to increased inflammation and higher risk of heart disease and other chronic conditions. Thus, the balanced ratio in hemp seeds makes them an excellent choice for heart health.

Incorporating Hemp Protein into Your Diet: Practical Tips and Recipe Ideas

Adding hemp seeds to your diet is straightforward and versatile due to their mild, nutty flavor. You can sprinkle them on salads, cereal, or yogurt or blend them into smoothies. They can also be used in baking or as a topping for various dishes.

For those looking to increase protein intake, hemp protein powder, made from ground hemp seeds, is available. This can be added to shakes and smoothies or baked as a partial substitute for flour.

Hemp milk, made by blending hemp seeds and water, is another nutritious and dairy-free alternative that can be used in cereals, coffee or enjoyed alone. Hemp seed oil can also be used in salad dressings, dips, or for drizzling over meals.

The Environmental Impact of Hemp Protein Vs. Other Plant-based Proteins

When considering the sustainability of a food source, it's essential to consider factors such as water usage, carbon emissions, and land requirements. Hemp is regarded as a sustainable crop for several reasons. It requires less water than other crops, including most plant-based protein sources. Hemp is also a sturdy plant that naturally resists pests, reducing the need for harmful pesticides.

Furthermore, hemp plants are known to absorb carbon dioxide at a high rate, reducing greenhouse gases. They also have the potential to remediate polluted soils through a process known as phytoremediation, making them beneficial for the environment beyond their nutritional value.

Comparatively, other plant-based protein sources, such as soy and peas, require more growth resources. Soy, in particular, is a primary driver of deforestation, and both crops often require significant amounts of pesticides and fertilisers.

Addressing Common Misconceptions About Hemp and Its Nutritional Profile

One of the biggest misconceptions about hemp is its association with marijuana. While both come from the Cannabis plant family, hemp does not have the psychoactive effects associated with marijuana. This misconception has led to regulatory challenges and public misconceptions that have hindered the broader acceptance of hemp as a nutritional powerhouse.

Another misconception is the belief that plant-based proteins are inherently inferior to animal-based proteins. While it's true that some plant proteins are incomplete, hemp is a complete protein containing all nine essential amino acids needed by the human body.

Finally, some might assume that hemp could contribute to weight gain or heart disease due to its high-fat content. In reality, the fats in hemp seeds are primarily healthy polyunsaturated fats. Furthermore, the balance of omega-3 to omega-6 fatty acids in hemp seeds is ideal for human health.

The Future of Hemp as a Sustainable Dietary Protein Source

With increasing interest in plant-based diets and sustainable farming practices, the future of hemp as a primary protein source looks promising. The nutritional profile and environmental benefits of hemp production position it as a frontrunner in the search for sustainable dietary alternatives.

Advancements in hemp cultivation, processing, and product development, coupled with progressive legislation, will likely continue to drive the hemp industry's growth. However, overcoming regulatory hurdles and public misconceptions will remain key to realising hemp's potential as a mainstream dietary protein source.
