What Vitamins Are Supplied By Dark Green Leafy Vegetables?
If you’re wondering ‘why eat green leafy vegetables?’, here’s your answer.
Plus, these vegetables have an abundance of carotenoids-antioxidants that serve to protect cells and may also be associated with lowering the risk of several types of cancer (8).
So, what are green leafy vegetables benefits?
Vitamin B complex comprises eight B vitamins: folate, thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, and cobalamin (3).
Each of these vitamins plays a significant role in your overall body health. The benefits of vitamin B complex include good eyesight, growth of red blood cells, good digestion, healthy brain function, cardiovascular health, proper nerve function, and energy metabolism (3).
The average daily recommended amount of vitamin K depends on the age of an individual. For adults, the recommended daily intake is 120mcg for men and 90mcg for women. Pregnant women also require 90mcg (35).
For Vitamin A ( carotene), the deeper the green or orange a vegetable is, the higher the amount of carotene it contains. The human body cannot manufacture its own vitamin A (31).
Vitamin A is necessary for many physiological processes in the body, such as maintaining all surface tissues like the skin, lining of the gut, respiratory tract, inner ear, and the eye (37).
The recommended daily intake of vitamin A is 900mcg for men and 700 mcg for women. Lack of adequate vitamin A in the body is known as vitamin A deficiency (VAD). Vitamin A deficiency makes the body susceptible to infections, increases the risk of diarrhea in children, and is the leading cause of preventable blindness in children (31).
Alpha-tocopherol is the only form of Vitamin E that meets human requirements (33).
This vitamin is absorbed in the small intestines and stored in the liver. It is a powerful antioxidant that helps maintain healthy cells. Furthermore, this vitamin inhibits platelet aggregation and protects against chronic diseases such as heart disease and cancer (33).
The recommended daily intake of vitamin E is dependent on the age of the person. For adults, the recommended daily amount is 15mg. It is very rare to consume excess vitamin E in food. However, ingesting high doses of alpha-tocopherol supplements is dangerous and can lead to poor blood coagulation and even hemorrhage (33, 34).
Vitamin C, also called Ascorbic Acid, is a water-soluble vitamin found in most fruits and vegetables. This vitamin can also be synthesized in the laboratory (32).
Whenever you talk of vitamin C, most people think about skin health. Nonetheless, there are other benefits of this vitamin, such as improved immunity, stimulating collagen synthesis, enhanced brain function, and good eye health (32).
A deficiency of this vitamin causes scurvy which is characterized by gum inflammation and bleeding. Low intake of Vitamin C can also contribute to anaemia since this vitamin aids in the absorption of iron.
