Vitamin A
Functions in the body
Vitamin A is a crucial nutrient that plays various vital roles in the human body. One of its primary functions is promoting good vision. It maintains the health of the eye’s retina and cornea, supporting optimal eyesight. Additionally, Vitamin A is essential for the growth and development of healthy skin and mucous membranes, acting as a protective barrier against harmful pathogens. It also plays a crucial role in the immune system’s function, helping to fight off infections and diseases.
Sources of vitamin A
To ensure an adequate intake of Vitamin A, it is important to consume foods rich in this nutrient. Some excellent dietary sources of Vitamin A include liver, fish oil, dairy products, eggs, and fortified cereals. Additionally, fruits and vegetables such as carrots, sweet potatoes, apricots, spinach, and kale are also great sources of provitamin A carotenoids which can be converted into Vitamin A in the body.
Symptoms of deficiency
A deficiency in Vitamin A can lead to several health issues. One of the earliest signs of deficiency is night blindness, where individuals struggle to see in low-light conditions. This can progress to a more severe condition called xerophthalmia, which causes dryness and damage to the cornea, leading to blindness if left untreated. Other symptoms may include dry skin, increased susceptibility to infections, and impaired immune function.
Recommended daily intake
The recommended daily intake of Vitamin A varies depending on age, gender, and life stage. For adult men, it is generally advised to consume about 900 micrograms of Vitamin A per day, while adult women should aim for around 700 micrograms.
