Pecan nuts contain many organic compounds and trace elements beneficial to the human body: vitamins B4, E, C, B3, B5, potassium, phosphorus, magnesium, calcium, and manganese. They are rich in omega-3 fatty acids. Oleic acid, monounsaturated fats, and antioxidants found in pecans are used to prevent heart attacks and strokes. Magnesium helps maintain the elasticity of blood vessels. Manganese helps mobilize the body's defense forces and increases immunity to infections. Phosphorus is essential for healthy bones and teeth, and also aids in detoxification. Vitamins A and E, along with ellagic acid, are antioxidants that slow down aging by preventing the harmful activity of free radicals. Vitamin B3 protects against the formation of cholesterol plaques in blood vessels. Carotene, abundant in pecans, has a positive effect on vision. B vitamins strengthen the immune system, help the nervous system cope with stress, and increase hemoglobin levels.
