What Is Vitamin A Good For
Its vital to consume enough foods rich in this vitamin as it affects many organs and systems in your body.
First, many people turn to vitamin A foods for eye health. Notably, the vitamin can prevent night blindness since it plays a significant role in converting light into electrical signals. People with this eyesight problem have difficulty adjusting to dim light, while their vision is not impaired when there is enough light. Also, beta-carotene lowers the risk of developing age-related macular degeneration.
Another vitamin A function is maintaining a healthy immune system. Since it stimulates the production of white blood cells responsible for fighting viruses, bacteria, and other foreign invaders, it can help your body resist infections. In line with this, recent studies have shown that vitamin A can reduce the risk of dying from measles.
Now, when it comes to the skin, what cannot be downplayed is the impact of vitamin A. Acne, for instance, could be reduced with its help. On top of that, there is beta-carotene, a potent antioxidant that can protect your skin from UV damage and slow down the signs of aging. In addition to eating foods containing this compound, you can use creams with retinol or retinoic acid.
How To Ensure You Get The Right Vitamins And Minerals In The Right Amounts
Vitamins and minerals are as essential for living as air and water. Not only do they keep your body healthy and functional, they protect you from a variety of diseases.
Vitamins and minerals get thrown together, but they are quite different. Vitamins are organic substances produced by plants or animals. They often are called “essential” because they are not synthesized in the body and therefore must come from food.
Minerals are inorganic elements that originate from rocks, soil, or water. However, you can absorb them indirectly from the environment or an animal that has eaten a particular plant.

Eat Foods High In Vitamin A With Healthy Fats
Vitamin A belongs to the group of fat-soluble vitamins. Therefore, we cant absorb vitamin A properly if we eat a low-fat diet.
Besides, fat can increase the conversion of carotenoids into usable vitamin A.
Fortunately, however, nature leaves nothing to chance. Thats why natural foods with vitamin A, such as fish, eggs, and dairy products, are equally rich in fat.
In particular, healthy animal fats like grass-fed butter or organic lard can help with retinol absorption.
Our grandmothers knew what they were doing when they used lard for cooking. Unfortunately, decades of advertising campaigns have turned even our grandparents into consumers of industrially refined oils instead.
In addition to improved nutrient absorption, animal fats have the advantage of being low in polyunsaturated fatty acids. In contrast, omega-6-heavy vegetable oils oxidize when heated, introducing free radicals into our bodies.
Nevertheless, not every vegetable oil is unsuitable. In contrast, virgin coconut oil has the highest amount of saturated fatty acids and is best suited for high temperatures. Moreover, olive and avocado oils are options for lower temperatures.
Vitamin A Deficiency Symptoms And Signs
Although this deficiency is rare in developed countries, it is prevalent in developing countries where people usually dont have enough vitamin A food. So what is the first sign of vitamin A deficiency? The most common symptom is night blindness, which is one of the first signs of xerophthalmia.
In a nutshell, it is an eye disease characterized by dryness of the conjunctiva and cornea. Vitamin A deficiency can also cause preventable blindness in children. Whats more, it can lead to anemia since people deficient in vitamin A often have low iron levels. Another serious consequence is the increased mortality risk of infectious diseases.

Retinol Activity Equivalents And The Vitamin A Daily Value
Since retinol and carotenoids do not offer the same bioavailability, the FDA recently mandated a new way of measuring the vitamin A content of food.
This measurement is called the retinol activity equivalent , which takes the low bioavailability of carotenoids into account.
These new guidelines state that 1 microgram of retinol activity equivalent is equivalent to
- 1 mcg retinol
- 12 mcg beta-carotene
- 24 mcg other carotenoids
In other words, retinol is deemed to be approximately 12x to 24x more valuable as a vitamin A source than carotenoids.
How Much Vitamin A Do I Need
The total vitamin A content of a food is usually expressed as micrograms of retinol equivalents .
The amount of vitamin A adults aged 19 to 64 need is:
- 700 µg a day for men
- 600 µg a day for women
You should be able to get all the vitamin A you need from your diet.
Any vitamin A your body does not need immediately is stored for future use. This means you do not need it every day.

Vitamin A Keeps Liver Healthy
Beta-carotene is a powerful antioxidant that keeps the liver free from cellular damage. Antioxidants are needed for good liver health as it processes all food consumed and comes into contact with many harmful products and chemicals that might lead to toxicity over a period of time. Liver problems can slow digestion and lead to many other health problems. Therefore eating vitamin A nutrient rich foods can help keep the liver safe from harm.
What Does The Department Of Health And Social Care Advise
You should be able to get all the vitamin A you need by eating a varied and balanced diet.
If you take a supplement that contains vitamin A, do not take too much because this could be harmful.
Liver is a very rich source of vitamin A. Do not eat liver or liver products, such as pâté, more than once a week.
You should also be aware of how much vitamin A there is in any supplements you take.
If you’re pregnant or thinking of having a baby:
- avoid taking supplements containing vitamin A, including fish liver oil, unless advised to by your GP
- avoid liver or liver products, such as pâté, as these are very high in vitamin A
Women who have been through the menopause and older men, who are more at risk of osteoporosis, should avoid having more than 1.5mg of vitamin A a day from food and supplements.
This means:
- not eating liver or liver products, such as pâté, more than once a week, or having smaller portions of these
- taking no more than 1.5mg of vitamin A a day in supplements if you do not eat liver or liver products
- not taking any supplements containing vitamin A if you eat liver once a week
Having an average of 1.5mg a day or less of vitamin A from diet and supplements combined is unlikely to cause any harm.
