“Those who take medicine and neglect nutrition are wasting the skills of their doctors .” Chinese proverb
Our diet is far more than just a source of energy; it influences numerous aspects of our health, including cognitive performance, mental balance, sleep, pain perception, inflammatory processes, and general well-being. At the center of these diverse interactions is a previously neglected control system in our body: the endocannabinoid system (ECS). This network of receptors and neurotransmitters functions as an internal balance system and is involved in the regulation of numerous biological processes. Recent research shows that certain foods and plant substances can specifically influence the ECS—with potentially far-reaching consequences for health and well-being.
The endocannabinoid system: The little-known control center
The ECS consists of three central components: the cannabinoid receptors (primarily CB-1 and CB-2, but possibly others), the body's own ligands (endocannabinoids), and the enzymes responsible for their synthesis and degradation. It is a vitally important system within the body that is responsible for homeostasis, or a healthy balance within the body, in response to changing external factors—such as stressful situations. The ECS is extremely versatile and controls numerous functions, including stress responses, pain perception, mood and well-being, sleep, appetite and energy balance, neuronal development and protection, as well as immune responses and many other functions.
A special feature of the ECS is that it operates "on-demand," meaning that endocannabinoids are produced when needed and only have a short-term effect. This makes the ECS particularly susceptible to external influences—such as diet, exercise, or stress.
Omega-3 and Omega-6 fatty acids: The building blocks of the ECS
Polyunsaturated fatty acids, particularly omega-6 and omega-3 fatty acids, provide the basis for the formation of endocannabinoids. Omega-6 fatty acids, especially arachidonic acid, serve as direct precursors for the endocannabinoids anandamide and 2-AG. A diet rich in omega-6 therefore promotes the formation of these endocannabinoids. However, an excess of omega-6—as is common in the Western diet, with a ratio of up to 16:1 to omega-3—can lead to overactivation of the ECS. This can promote inflammation, obesity, and metabolic disorders.
Omega-3 fatty acids, found in fatty fish, hemp, flaxseed, walnuts, pumpkin seeds, rapeseed oil, and chia seeds, act as antagonists: They promote the formation of endocannabinoid-like molecules such as DHEA, which have anti-inflammatory effects and can restore balance to the ECS. A balanced ratio of omega-6 to omega-3, ideally 4:1 or even lower, is essential to optimally support the ECS and regulate inflammatory processes in the body.
The ratio can also be improved by reducing foods high in omega-6 in your diet; these include highly processed foods, convenience foods, sunflower oil, safflower oil, and large amounts of meat and sausages, as they contain particularly high levels of omega-6.
Hemp foods: More than just a trend
Hemp products such as hemp seeds, hemp oil, and hemp protein have become veritable superfoods in recent years—and rightly so. Hemp seeds not only contain high-quality plant-based protein, but also a nearly ideal ratio of omega-6 to omega-3 fatty acids of approximately 3:1. This provides a perfect foundation for supporting the ECS through nutrition.
But hemp can do even more: In addition to valuable fatty acids, the plant also contains traces of phytocannabinoids such as cannabidiolic acid (CBDa). In the hemp plant, cannabidiol (CBD) initially only exists as CBDa. Only through heating (e.g., during drying, cooking, or extraction) is CBDa converted into CBD, a process known as decarboxylation. Neither CBDa nor CBD are as psychoactive as THC; CBD may even weaken the psychoactive effects of THC . However, CBDa and CBD differ in structure, bioavailability, and effects: CBDa is better absorbed by the body and has a different effect on the endocannabinoid system than CBD. While CBD has been better researched, initial preclinical studies show that CBDa may have its own, sometimes more potent, effects, for example on inflammation or nausea.
In addition, there is evidence that certain aromatic terpenes such as beta-caryophyllene or limonene and other secondary plant substances from hemp can interact with the ECS and modulate its function - for example, by increasing the availability of the body's own endocannabinoids or supporting anti-inflammatory signaling pathways.
Hemp is easy to integrate into everyday life: Two to three tablespoons of hemp seeds in muesli, a spoonful of hemp oil over a salad, or a spoonful of hemp protein in a smoothie can all help support a balanced diet. When preparing hemp tea, be sure to pour hot, but not boiling, water over the leaves to preserve the terpenes as much as possible.
Plant power for the ECS: Pepper, Echinacea, Maca and more
In addition to hemp and cannabis, there are other plants that can specifically modulate the ECS. Particularly interesting are black pepper, echinacea, turmeric, maca, and kava kava.
Black pepper (beta-caryophyllene)
Beta-caryophyllene is a terpene found in black pepper, oregano, rosemary, and also hemp. Preclinical studies suggest that it may interact with the endocannabinoid system and exhibit anti-inflammatory and pain-relieving effects in animal models. However, these preliminary findings come primarily from experimental laboratory settings—human clinical trials are still pending. This also largely applies to the foods described below.
Coneflower (Echinacea)
Echinacea contains so-called N-acylethanolamines, which are structurally similar to the body's own endocannabinoids. Preclinical studies suggest that these plant substances interact with CB2 receptors of the endocannabinoid system and can influence inflammatory signaling pathways in cell and animal models. Effects on immune responses, such as the inhibition of certain inflammatory messengers, have been observed. Whether and how these findings can be transferred to humans is the subject of current research.
Turmeric (curcumin)
According to preclinical studies, curcumin, the bright yellow pigment from turmeric root, inhibits the enzyme FAAH, which otherwise breaks down the endocannabinoid anandamide. This increases anandamide levels in the body, which could have a positive effect on mood, pain perception, and inflammatory processes. Combining it with black pepper (piperine) increases the bioavailability of curcumin many times over.
Maca (Lepidium meyenii)
The Peruvian root contains N-alkylamides, which act as FAAH inhibitors and slow the breakdown of anandamide. This increases the concentration of this "happy molecule" in the body, potentially promoting stress-reducing and neuroprotective effects. Preclinical studies also suggest a synergistic effect with CBD.
Kava Kava (Piper methysticum)
Kava kava is a traditional medicinal plant from the South Pacific. The root contains kavalactones such as yangonin, which act on the CB1 receptor and thus potentially have anxiolytic and relaxing effects. Kava extracts are traditionally used for relaxation in certain cultures. Clinical research into their applications is still ongoing.
Practical nutritional tips for a strong ECS
Those who want to specifically support their endocannabinoid system should pay attention to a balanced, predominantly plant-based diet. The following are particularly recommended:
• Omega-3 rich foods: Fatty fish (e.g. salmon, mackerel), flax seeds, chia seeds, walnuts, hemp seeds and hemp oil
• Omega-6 reduction: Avoid sunflower oil and prefer olive oil or rapeseed oil instead.
• Botanicals: Turmeric (best combined with black pepper), hemp products, herbs such as oregano and rosemary, grapes
Regular exercise, sufficient sleep and stress management also support the healthy function of the ECS.
Conclusion
Science is increasingly demonstrating that the endocannabinoid system is a crucial key to health, well-being, and disease prevention. With a balanced diet rich in omega-3 fatty acids and targeted use of plant compounds such as curcumin, beta-caryophyllene, and kavalactones, we can actively support our ECS. Cannabis plays a central role in this – the plant not only provides valuable fatty acids but also secondary plant compounds that naturally modulate the ECS.
We still have a lot to learn, but one thing is clear: the future of nutrition is personalized, plant-based – and targets the endocannabinoid system.
