Cortisol is a steroid hormone that plays a key role in the body and can impact skin, scalp and hair health. It is often referred to as the stress hormone as it is released into the bloodstream in a fight or flight situation, increasing heart rate and blood pressure. A plant-based diet is associated with lower levels of cortisol as well as lower stress, anxiety and depression. This is because a vegan diet does not include animal products, which have been linked to higher cortisol levels. In contrast, a plant-based diet includes foods such as fruits, vegetables, grains and legumes, which are rich in nutrients that help to lower cortisol levels.

What You'll Learn
Plant-based diets are associated with lower cortisol levels
Cortisol, often referred to as the "stress hormone", is a steroid hormone that plays a crucial role in the body's response to stress. It is released by the adrenal glands during stressful situations, triggering the "fight or flight" response. While cortisol has a negative connotation, it is essential for several bodily functions, including regulating blood sugar levels, metabolism, reducing inflammation, and memory formulation.
However, chronically high cortisol levels can lead to various health issues. Prolonged exposure to high cortisol levels can result in tissue breakdown, reduced protein synthesis, increased abdominal fat, suppressed growth and sex hormones, and an elevated risk of diabetes and osteoporosis. Additionally, high-protein diets that include animal products can further increase cortisol levels, leading to adverse health effects.
This is where plant-based diets come into the picture. Research has shown that diets rich in whole, plant-based foods are associated with lower cortisol levels. These diets emphasize fruits, vegetables, grains, and legumes, while minimizing the use of oil and salt. On the other hand, Western-style diets, characterized by high intakes of refined carbohydrates, animal proteins, and saturated fats, are linked to higher cortisol release.
The benefits of plant-based diets extend beyond just lowering cortisol levels. They are also associated with improved hydration, increased intake of vitamins, minerals, and antioxidants, reduced risk of cardiovascular disease, better blood glucose control, and a lower risk of certain cancers.
Additionally, specific plant-based foods have been identified as effective cortisol-lowering agents. These include green leafy vegetables, such as kale and spinach, which are rich in folate and help regulate mood. Dark chocolate, in moderation, has also been shown to reduce cortisol levels due to its antioxidant properties. Fermented foods, such as kombucha and kimchi, can also help lower stress by introducing beneficial probiotics into the gut.
In conclusion, plant-based diets, rich in whole foods, play a crucial role in maintaining lower cortisol levels and promoting overall health and well-being. By incorporating a variety of plant-based options and adopting a mindful approach to eating, individuals can effectively manage their cortisol levels and potentially reduce the negative impacts of stress on their bodies.

Vegan diets reduce the risk of high blood pressure and high cholesterol
Vegan diets are associated with a range of health benefits, including reduced risk of high blood pressure and high cholesterol. Adopting a vegan lifestyle can be a positive step towards improving overall health and well-being. Here are some key points to consider:
Lower Blood Pressure and Cholesterol
Vegan diets have been linked to lower blood pressure and cholesterol levels. High levels of cortisol, often referred to as the "stress hormone," are associated with increased blood pressure and cholesterol. A single meal containing animal products may double the amount of cortisol in the blood, whereas cortisol levels tend to decrease after a vegan meal. This reduction in cortisol can have a positive impact on cardiovascular health, lowering the risk of hypertension and related complications.
Improved Cardiovascular Health
Vegan diets are often rich in fruits, vegetables, grains, and legumes, which are good sources of nutrients that support cardiovascular health. These whole foods are typically low in saturated fats and cholesterol, helping to maintain healthy cholesterol levels and promote a healthy heart. Additionally, a well-planned vegan diet can provide improved blood glucose control and insulin sensitivity, further contributing to reduced risk of cardiovascular disease.
Healthy Weight Management
Vegan diets can also aid in weight management, which indirectly reduces the risk of high blood pressure and cholesterol. Plant-based diets tend to be lower in calories and higher in fiber, promoting a healthy weight and reducing the risk of obesity. Obesity is a significant risk factor for high blood pressure and high cholesterol, so maintaining a healthy weight through a vegan diet can be beneficial.
Anti-Inflammatory Effects
Vegan diets have been shown to have anti-inflammatory effects, which can positively impact cardiovascular health. By cutting out animal products, particularly chicken and eggs, vegan diets can reduce the intake of arachidonic acid, an inflammatory compound for the brain. This reduction in inflammation can have a positive impact on overall health, including the cardiovascular system, and may contribute to a lower risk of high blood pressure and cholesterol.
Micronutrient Considerations
While vegan diets offer numerous benefits, it is important to ensure adequate micronutrient intake. Well-planned vegan diets can provide sufficient protein, calcium, and other essential nutrients, but deficiencies in vitamin B12, essential amino acids, and vitamin D can occur if meals are not carefully considered. Including a variety of plant-based protein sources, such as tofu, beans, and legumes, can help meet nutritional needs and support overall health.

Green leafy vegetables, dark chocolate, and fermented foods are stress-relieving
Green leafy vegetables, dark chocolate, and fermented foods are indeed stress-relieving. This is because they can help to reduce cortisol, the body's primary stress hormone.
Green leafy vegetables such as kale and spinach are rich in folate, which helps the body manufacture neurotransmitters like serotonin and dopamine, which regulate mood. They are also packed with vitamins, minerals, and fiber, and are low in calories. A diet rich in leafy greens may help boost brain health and lower the risk of obesity, heart disease, high blood pressure, and mental decline.
Dark chocolate has been found to reduce stress hormones, including cortisol. It contains antioxidants that relax the walls of blood vessels, lowering blood pressure and enhancing circulation. The higher the cocoa content, the better it is for your health, so opt for dark chocolate with 80% cocoa or higher.
Fermented foods such as sauerkraut, kimchi, and dairy-free yogurt contain the probiotic lactobacillus rhamnosus, which can lower the stress-induced hormone corticosterone and help ease stress. Research has also linked gut health to overall health, and fermented foods are important for keeping the good bacteria in the gut healthy.
Incorporating these foods into your diet can be a great way to help manage stress and support your overall health.

A plant-based diet can help with adrenal fatigue
Adrenal Fatigue Syndrome (AFS) is a condition that is greatly influenced by what you eat. Diet is the biggest factor in adrenal fatigue recovery after getting proper rest and reducing stress levels. A plant-based diet can help with adrenal fatigue by reducing cortisol levels in the body. Cortisol is a steroid hormone produced in the adrenal cortex, testes, and ovaries. It is often referred to as the "stress hormone" as it is released during fight-or-flight situations.
A plant-based diet can help lower cortisol levels, which is beneficial for managing adrenal fatigue. Research shows that diets emphasizing whole, plant-based foods are associated with lower stress, anxiety, and depression. This includes fruits, vegetables, grains, and legumes, with minimal use of oil and salt. In contrast, a Western-like diet, characterized by high intakes of refined carbohydrates, animal proteins, and saturated fats, is associated with higher cortisol levels.
By adopting a plant-based diet, individuals can reduce their cortisol levels and manage their adrenal fatigue more effectively. However, it is important to note that a well-planned vegan diet is crucial, ensuring adequate nutrient intake and addressing potential deficiencies, such as vitamin B12, essential amino acids, and vitamin D.
Additionally, a plant-based diet offers other health benefits that can positively impact overall wellness. It provides improved hydration due to the high intake of water-rich fruits and vegetables, an abundance of vitamins, minerals, and antioxidants, and a reduced risk of cardiovascular disease and certain types of cancer.
