WHAT IS VITAMIN A
Vitamin a is a fat-soluble vitamin that is good for healthy vision, skin, bones and other tissues in the body. Vitamin often works as an antioxidant, fighting cell damage, but it also has many other uses.
Through its role with cell growth and division, vitamin a has a vital role in the healthy formation and maintenance of the heart, lungs, kidneys and other vital organs.
There are two types of the vitamin. Preformed vitamin a, also called retinol, is found in animal products. Good sources are fortified milk, eggs, meat, cheese, liver, halibut fish oil, cream and kidneys. Pro-vitamin is found in plant-based foods such as fruits and vegetables.
The most common type of pro-vitamin a is beta-carotene, a carotenoid that produces dark pigments in plant foods. Beta-carotene can be found in these brightly coloured foods:
Dark green, leafy vegetables
Vitamin a has many varied functions. Retinol not only creates the pigments in the retina of the eye but also is integral for good vision, especially night vision, and overall eye health.
An age-related eye disease study by the national eye institute found that taking high levels of antioxidants, such as vitamin a, along with zinc, may reduce the risk of developing advanced age-related macular degeneration by about 25 percent. Age-related macular degeneration is the most common cause of loss of vision in the older population.
Vitamin an also helps skin grow and repair skin. This being the case, it is the active ingredient in most Retin-A type products out today. Retin-a is a brand name for tretinoin, a prescription medication that treats acne and other skin conditions.
It works by signalling to the cells to grow at a faster rate, bringing fresher, more youthful skin to the surface more rapidly. Used in excess, it can be quite irritating, however.
Other functions of vitamin a include the formation and maintenance of teeth, bones, soft tissue, white blood cells, the immune system and mucous membranes. Beta-carotene also acts as an antioxidant, protecting cells from free radical damage.
Though many antioxidants prevent cancer, there is no evidence that beta-carotene supplements are helpful in the prevention of cancer. On the other hand, all-natural beta-carotene that can be consumed through vegetables and fruits has been found to help in preventing cancer in many studies.
When we discuss juicing recipes for vitamin a in all actuality, we are looking at juicing for beta-carotene. Beta-carotene is a cancer prevention agent of the carotenoid family that shows up in numerous fruits and vegetables, and our livers can change over it into vitamin an as required.
One great approach to tell if a fruit or vegetable contains beta-carotene is by its shading. Beta-carotene is responsible for putting the orange tone into various fruits and vegetables.
So carrots, summer squash, sweet potatoes, mangoes and cantaloupe melons are all awesome wellsprings of beta-carotene.
The deeper the orange shading of a fruit or vegetable, the more beta-carotene it will contain. Therefore, carrots are the best-known food wellspring of beta-carotene and particularly carrot juice.
A juicing machine will break open the intense fibres of carrots and discharge a more significant amount of the beta-carotene from the fibres for us to process. So carrot juice is a superior wellspring of beta-carotene than really eating carrots.
Another little tip is that more beta-carotene is processed when it is joined by fat or oil. Adding somewhat olive oil to your carrot juicing recipes will like this enhance the bioaccessibility of beta-carotene.
There are green shaded vegetables that are an incredible wellspring of beta-carotene as well. Kale, spinach and broccoli are prime illustrations. It is only that the chlorophyll (a plant shade that produces the shading green) substance of kale, spinach and broccoli out ways the beta-carotene content.
