Vitamin A is a type of fat-soluble vitamin and it plays an important role in maintaining healthy vision and skin, neurological functionality, and reducing inflammation through fighting free radical damage. Nutritionally, vitamin A required by the human body can be obtained from two primary sources which are from animal sources and plant sources [33]. The animal-derived sources can be obtained in a form of retinol (active Vitamin A), which can be used directly by the body. For plant-derived Vitamin A, which can be obtained from fruits and vegetables, it is in the form of pro-Vitamin A such as beta-carotene and related carotenoids, which have to be converted to retinol after being consumed in order to be fully utilized by the body [127].

The term “retinoid” includes both the naturally occurring compounds with vitamin A activity and synthetic analogs of retinol. Vitamin A (retinol) is essential for normal growth, vision, reproduction, and so on. The retinoids are very sensitive to light and oxidation. Therefore, special care has to be taken from the beginning of sample collection until the final step. A general description can be found in References.160–164 Factor effects of plasma or serum concentration and validation of method has been described in the previous section.

The conversion of the β-carotene supplement into vitamin A and atRA might be the chief regulatory factor for hepatoprotection. Vitamin A can be consumed directly from the diet, usually in the form of retinol or retinyl esters from a variety of meat and dairy products. In addition, it can also be produced via β-carotene 15,15′-monooxygenase–mediated cleavage from dietary provitamin A carotenoids (α-carotene, β-carotene and β-cryptoxanthin) (Lietz et al. 2012).

Antioxidant nutrients, including vitamin C (ascorbic acid), carotenoids (vitamin A) and vitamin E [tocopherols and tocotrienols classified as alpha (α), beta (β), gamma (γ) and delta (δ)], are recommended following the “Dietary Reference Intake” (DRI) according to the Instituto National Cancer Institute (Instituto National Cancer Institute (INCA) 2020). These vitamins delay or inhibit oxidation, and lower free radical concentrations in the body thus, preventing cancer (Instituto National Cancer Institute (INCA) 2020). At low doses in the diet, vitamins block the effectiveness of antineoplastic agents to damage non-tumor cells. However, vitamins at high doses might become pro-oxidants increasing oxidative stress and eventually promoting carcinogenesis (De Carvalho et al. 2017; Gasparoto et al. 2015; Kazmierczak-Baranska et al. 2020; Vivarelli et al. 2019).
Production of vitamin A and vitamin E: expression of vitreoscilla hemoglobin gene in Erwinia herbicola

Vitamin A prevents eye problems and blindness. It prevents skin problems by strengthening the immune system. It also treats ulcers in the digestive system; protects the body against colds and infections in the kidneys, bladder, lungs and mucous membranes.[7] Vitamin E is a nutrient that has important roles in many areas such as skin health, eye health and hormonal order. At the same time, vitamin E, which is one of the vitamins with antioxidant properties, is also very effective in strengthening the immune system.[8,9] Vitamin E, which is also an antioxidant vitamin, prevents them from causing harmful consequences on the body by reducing free radicals. In this way, it reduces oxidative stress, prevents the formation of genetic damage in cells, and helps fight many diseases, especially cancer. Vitamin E, which contributes to the strengthening of the immune system, contributes to the protection of the body against infectious diseases when taken in sufficient amounts.[10] Vitamins also produce several microorganisms owing to genetic engineering and industrial biotechnology.

In our study we found four nutrients that are able to be influenced, if the healthiest options were chosen by the clients, to increase the diet quality of the food basket. As noted above, these include vitamin A, fiber, carbohydrates, and trans-fat. The ideal shoppers chose higher amounts of vitamin A and fiber, and lower amounts of carbohydrates and trans-fat. Vitamin A is important for normal vision, to help to protect the immune system, to aid in reproduction, and to help the heart, lungs, kidneys, and other organs work properly.36 In the United States (US), a deficiency of vitamin A is rare.36 However, despite the typical adequacy of vitamin A in the US diet, we reported on this nutrient due to its statistical significance and also since it was found to be low in other research analyzing specific nutrients in food baskets.25
