Beta-carotene is a fat-soluble pigment found in orange and yellow fruits and vegetables that can be converted into vitamin A. It is an antioxidant that may protect against chronic diseases, but there is no recommended daily intake. Beta-carotene deficiency may be common in those with low fruit and vegetable intake, and supplements should be used with caution as excessive amounts can have negative side effects. It is recommended to obtain beta-carotene through whole foods.
Beta-carotene is a naturally occurring nutrient found in many orange and yellow fruits and vegetables. It is part of a class of fat-soluble pigments called carotenoids that dissolve in fat within the body. When ingested, beta-carotene is converted first to retinol and then to vitamin A. Both beta-carotene and vitamin A help maintain the health of the body’s cells. Beta-carotene supplements provide a way to increase the level of vitamin A in the body for those who do not eat enough in their diet.
Beta-carotene is considered an antioxidant, and there is evidence to suggest that it may protect against chronic diseases, such as cancer and heart disease. It provides protection for the cells of the body, enhances the immune and reproductive systems, and provides a necessary source of vitamin A. Sweet potatoes, kale, carrots, winter squash, kale, and broccoli are some of the vegetables that They are naturally rich in beta-carotene. The health benefits of consuming beta-carotene through whole foods or using beta-carotene supplements have been recognized.
Studies related to beta-carotene have not yet provided sufficient evidence to determine a recommended level of beta-carotene intake. Despite years of research, there are still no formally established nutritional guidelines for your RDA. Although formal guidelines for beta-carotene levels have yet to be finalized, research has provided general nutritional guidelines. Most studies suggest that adults should have about five servings of fruits and vegetables every day. Eating the recommended diet will provide between three and six milligrams of beta-carotene per day.
Statistically, most average diets are low in fruits and vegetables. Beta-carotene deficiency may be more common in those who have diets low in fruits, vegetables, and lower than average fat content or blood levels. Those who meet the criteria for beta-carotene or vitamin A deficiency may benefit from beta-carotene supplementation. Although beta-carotene supplements are available without a prescription, it is always recommended to consult with a health care provider before beginning any supplement.
Excessive amounts of beta-carotene are not recommended, and there are specific warnings against high amounts for tobacco and alcohol users. Synthetic beta-carotene supplements have been shown to increase the risk of some types of cancer. High levels can cause side effects such as skin discoloration or a yellow tinge to the whites of the eyes. Studies have shown that intake of beta-carotene in amounts greater than 20 milligrams per day can increase the chances of cancer and heart disease, specifically in those who smoke and drink alcohol regularly.
There is evidence of a positive correlation between general health and body function and the presence of average levels of beta carotene and vitamin A. It is recommended that beta carotene has less risk and more benefit when obtained through whole foods rather than take beta-carotene supplements. Supplements offer the next best alternative to a diet rich in foods that contain healthy nutrients.
