Vitamin A helps maintain vision, support immunity, and promote skin health. Including it in your daily diet through balanced nutrition can help support overall wellbeing. Alongside preventive care, having the best health insurance ensures you are financially prepared for any health-related concerns that may arise. But a healthy diet, exercising regularly, and going for routine check-ups are the beginning.
This blog will explain vitamin A’s benefits, how you can get it, and how having too much or too little affects you.
All You Need to Know about Vitamin A and Its Benefits
Vitamin A is a fat-soluble nutrient essential for the smooth functioning of several physiological processes of the human body, from immune system maintenance to skin cell replacement. Since our bodies cannot produce vitamin A, it’s important to include vitamin A foods in your diet.
The recommended dietary allowance (RDA) for adults is 900 mcg for men and 700 mcg for women daily. For pregnant and lactating women aged 19 years and older, daily doses of 770 and 1300 mcg are recommended, respectively. The recommended daily dose for children increases with age, underscoring its vital role in growth.
Sources of Vitamin A
Vitamin A can be found in plant and animal sources, which ensures that you are eating a balanced diet. Plant sources contain carotenoids, the plant-based form of vitamin A, which is converted to vitamin A after it is consumed. This includes dark green-coloured vegetables such as spinach, chard, and amaranth, along with carrots, pumpkins, squash, mangoes, papaya, and maize. The animal sources include liver, fish liver oil, dairy products, and eggs. Besides, vitamin A can be found in red palm oil.
Benefits of Vitamin A
It is necessary to take the recommended dose of vitamin A for a healthy body, either through a balanced diet or through a multivitamin supplement. This nutrition plays a vital role in bodily functions, with benefits such as:
- Physiological Processes: It supports physiological processes, such as ensuring that tissues produce mucus to act as a barrier against infection. It also supports cell growth, reproduction, and immune defence.
- Prevents Cancer: The antioxidants in vitamin A, along with retinoic acid, are said to help prevent several types of cancer, including colon, breast, and skin cancer.
- Skin Health: Vitamin A deficiency can cause several skin problems, and excess intake can cause dry, itchy skin. Since it supports skin cell growth, it is a necessary nutrient for healthy skin.
- Supports the Immune System: Vitamin A supports several functions of the immune system. Its deficiency can weaken the immune system, leading to increased infections.
- Improves Eye Health: Vitamin A in balanced doses helps improves night vision by helping the eyes adjust to changes in light and keeps the eyes moist. It can also reduce the risk of cataracts and macular degeneration, which are causes of vision loss.
Vitamin A Deficiency
Although rarely seen in developed countries, vitamin A deficiency can cause xerophthalmia (dryness of the eye), skin problems, and increased susceptibility to infection, especially in children. In severe cases, it also results in night blindness. People suffering from chronic liver disease or malnutrition and alcoholics have a higher chance of having vitamin A deficiency.
Excess of Vitamin A
While vitamin A deficiency has harmful effects, so does an excessive intake of this nutrient. Symptoms of excess intake include dry skin, nausea, hair loss, fatigue, dizziness, osteoporosis, and liver damage.
In the case of pregnancy, it is advisable to avoid vitamin A supplements as well as liver and liver oil. Excess vitamin A intake in pregnancy is known to cause birth defects such as malformation of the skull, eyes, and heart.
Managing Vitamin A Intake
Vitamin A is an essential nutrient for everyone, but an imbalanced intake can do your body more harm than good. Deficiency or excessive intake of this nutrient can lead to severe consequences, such as night blindness and birth defects. Know what the RDA of vitamin A is for your body to ensure and maintain healthy bodily functions.
Conclusion
Focusing on balanced nutrition and regular health check-ups can help you maintain adequate vitamin A levels and prevent related deficiencies. A good health insurance policy will promote wellness activities like consulting a nutritionist, which will help you to get the proper intake of vitamin A. Along with this, it is important to get yourself and your family a suitable family health insurance plan, which will provide you with financial assistance for treatment.
