Vitamin A deficiency has become a major health issue in many parts of the world. In fact, vitamin A deficiency is responsible for over 1 million deaths per year worldwide.
Vitamin A deficiency is a serious problem in developing countries where poor diets are common. But even in developed countries, vitamin A deficiency is becoming increasingly prevalent as people consume less animal products and more processed foods.

Why Vitamin A Is Important
Vitamin A is essential for vision, bone growth, immune system function, reproduction, and cell differentiation. In fact, vitamin A deficiency causes night blindness, poor vision, and tooth decay.
The World Health Organization estimates that over 250 million people worldwide suffer from vitamin A deficiency, including nearly half of children under 5 years of age. This number is expected to rise to 400 million by 2020 unless there is a dramatic change in dietary habits.
To prevent vitamin A deficiency, eat foods rich in beta-carotene (like carrots), consume fortified dairy products, and get plenty of exposure to sunlight.

How Much Vitamin A Do You Need
The amount of Vitamin A you need depends on your age, gender, lifestyle, and health condition.
If you’re pregnant, breast feeding, or taking medications, consult your doctor before supplementing with Vitamin A. In general, adults require between 400 IU (international units) and 800 IU per day. Children and teenagers require 500 to 1,000 IU daily. Women who are pregnant or nursing should avoid supplements containing beta carotene because they may cause birth defects.
What Is Vitamin A Deficiency?
Vitamin A deficiency is a condition where there is insufficient intake of vitamin A in the body.
When the body does not receive adequate amounts of vitamin A, it cannot properly absorb nutrients such as iron, calcium, zinc, and protein.
As a result, these essential vitamins and minerals do not reach the cells of the body.
Without proper absorption of these nutrients, the body becomes deficient in them.
Causes of Vitamin A Deficiency
There are two main causes of vitamin A deficiency:
Poor dietary habits
Poor dietary habits include eating too little food containing vitamin A.
For example, consuming too much sugar or refined carbohydrates leads to low levels of vitamin A in the bloodstream.

Malnutrition occurs when people eat an inadequate amount of fruits and vegetables.
