10 Foods & Habits That Support Your Body's Endocannabinoid System

Here, I dive into why exactly the ECS is so important and various ways to support its functioning via simple diet and lifestyle changes—which, in turn, will help you reap even more benefits from your hemp or CBD product. 

In fact, more and more research is showing the connection between a variety of health problems and low endocannabinoid levels, similar to how a deficiency in neurotransmitters can be linked to other health problems like depression. In research this is referred to as "clinical endocannabinoid deficiency," and it can play a role in autism1, migraines, fibromyalgia, and irritable bowel syndrome2. And these are just the beginning as the research surrounding the ECS continues to grow. 

The great thing about endocannabinoids is that, since your body naturally produces them, you can do things to naturally trigger or enhance their production. Here are 10 simple ways to improve the functioning of your endocannabinoid system:

Moving your body in some way is beneficial for so many areas of your health, including the endocannabinoid system. Exercise can both increase levels of your natural CB1 activator, anandamide3, as well as your CB1 receptor sensitivity4.

Spending a summer day outdoors can do wonders for your mood—and many experts recommend spending up to 20 minutes in the sun daily without sunscreen. This not only helps you soak up vitamin D, it also enhances your ECS. That's because UVA rays from the sun promote5 nitric oxide activity in the body, and, in turn, nitric oxide boosts abundance and expression of CB1 receptors.

The more we learn about certain fats, the more we move far, far away from the belief that "fat is bad." And it turns out, endocannabinoids are produced6 from the omega-6 fatty acid arachidonic acid. But balance is key, as too much arachidonic acid can also inhibit cannabinoid receptors and increase inflammation. So, what should you eat? Making sure you have a healthy ratio of omega-3 and omega-6 fatty acids is essential to reap the endocannabinoid benefits. You can find a healthy ratio of these omega fatty acids in eggs, flaxseeds, hemp seeds, chia seeds, salmon, and wild-caught sardines (basically, my pescatarian-friendly Ketotarian staples).

Living in Pittsburgh, I'm no stranger to cold weather—and I've really come to appreciate it now that I know the perks, including the fact that cold exposure has been shown to stimulate the endocannabinoid system. So instead of hiding away come winter, make an effort to go on more walks or get outside in some way. And if you are one of the lucky people who live in warm-weather climates year-round, try a blast of cold water in the shower.

Stress has been implicated in a variety of health conditions. In fact, I often see patients who note that their symptoms first began after a stressful life event. When you are emotionally stressed, your stress hormone cortisol is elevated. When this happens, it can reduce7 hippocampal CB1 receptors in the brain, which leads to lower cannabinoid function. And when you are chronically stressed, these CB1 receptors are chronically inhibited. So, take any steps you can to reduce your overall stress load, from exercise to meditation to getting plenty of sleep.

Electrolytes such as calcium, magnesium, and potassium are important for keeping you hydrated, regulating your body's pH levels, and basically just keeping your body functioning at 100%. Studies have shown8 that adequate amounts of calcium and potassium boost CB1 transport and activity.

This fat-soluble vitamin helps keep your immune system9 strong and increases CB1 expression10. You can find vitamin A most abundantly in wild-caught fish, wild-caught shellfish, cod liver oil, liver, grass-fed butter, and ghee. While you can also obtain vitamin A through sweet potatoes and carrots, which contain precursors to vitamin A called carotenes (including beta-carotene), the conversion rate to the usable form of vitamin A (retinol) is fairly low, at about 3%11.

Not like you need encouragement to eat more chocolate, but now you have it: Dark chocolate happens to contain the endocannabinoid, anandamide, as well as compounds that slow the breakdown of this endocannabinoid, which helps stimulate your endocannabinoid system even further.

No list of mine would be complete with tea, and here's yet another benefit to add to its resume. Tea contains antioxidant compounds known as catechins that work to enhance12 the endocannabinoid system by binding to cannabinoid receptors in the central nervous system. Green tea is abundant in the catechin antioxidant Epigallocatechin gallate (EGCG), which is particularly potent.

While some things can enhance the endocannabinoid system, some things can also inhibit it. Pesticides and chemicals like phthalates in plastic can block the activity13 of the endocannabinoid system, which is important to note since these are two things that are extremely common in our everyday lives. Aim to reduce your exposure by opting for organic produce and using eco-friendly storage options made from glass and stainless steel.
