A balanced and regular diet can help promote beautiful and healthy skin. Nutrients include animal and plant proteins, as well as vitamins B, E, C, and more. In particular, Vitamin B, aptly nicknamed the "beauty vitamin," can even be used in the treatment of skin diseases. These B-complex vitamins, C, and E can help keep capillaries clear and continuously supply the nutrients the skin needs to promote the growth of healthy and supple skin.

1. Lack of Vitamin A: Premature Skin Aging
Chondroitin sulfate is a viscous polysaccharide, and its synthesis requires a large amount of Vitamin A. A deficiency in Vitamin A naturally leads to a decrease in chondroitin sulfate synthesis, affecting skin health.
In fact, whether it's skin aging caused by a Vitamin A deficiency or the natural aging process, both are related to a reduced ability to synthesize chondroitin sulfate. Therefore, a Vitamin A deficiency can accelerate skin aging.
Vitamin A is also a nutrient for important endocrine hormones such as the hypothalamus and pituitary gland. When it is insufficient, it cannot send proper signals for hormone secretion from the ovaries, leading to decreased ovarian function and a relative increase in male hormones. This makes the skin prone to acne, affecting its appearance.
The conversion rate of carotene from colored vegetables into Vitamin A is very high, so people can obtain sufficient Vitamin A from vegetables. However, if there is a lack of animal-based foods, carotene cannot be effectively converted into Vitamin A. Therefore, to maintain a youthful and beautiful appearance, one should consume as many animal-based foods high in Vitamin A as possible, such as liver, lean meat, and egg yolks.
2. Lack of Vitamin B2: Prone to Acne
The rice, flour, and oils we consume are converted into body fat. When it exceeds the body's needs, the fat is secreted through the skin's sebaceous glands or stored within the pores. Fat in the pores is often a breeding ground for mites and pus-forming bacteria, so excess fat can easily lead to acne, folliculitis, and rosacea.
A Vitamin B2 deficiency can promote these conditions. This is because "burning" fat requires a large amount of Vitamin B2. Without it, fat is stored in the pores, increasing skin secretions and leading to acne.
The "burning" of fat not only requires Vitamin B2 but also methionine. Methionine is found in very small amounts in grains and vegetables but is abundant in animal-based foods such as meat, liver, fish, and eggs. Meat, liver, fish, and eggs are also rich in B vitamins. To maintain beautiful skin, one should eat more of these foods.
3. Lack of Vitamin C: Prone to Enlarged Pores
Many experts, through multiple Vitamin deficiency experiments and case studies, have found that a Vitamin C deficiency causes skin pores to enlarge and become hard, like needles. Under a microscope, a horn-like plug can be observed in the pores. The hair cannot extend and curls inside the pore. The blood vessels around the pore enlarge and become congested, which can worsen acne and make wounds difficult to heal.
Vitamin C also enhances the function of white blood cells, enabling them to engulf pus-forming bacteria. Vegetables contain flavonoids and Vitamin C. If these are sufficient, pus-forming bacteria stop secreting enzymes. Therefore, people who eat a lot of vegetables are less prone to folliculitis, and their skin is glossy and beautiful. Flavonoids are the yellow substance dissolved in vegetable juice, with rutin being a prime example.
In summary, beautiful skin is closely related to Vitamins A, B, C, and methionine. It would not be an exaggeration to say that these nutrients ensure the beauty of our skin. With the exception of Vitamin C, these nutrients are abundantly found in animal-based foods such as lean meat, liver, fish, and eggs. Vitamin C is found in fresh yellow-green vegetables. Therefore, we should carefully design our diets to obtain sufficient nutrients from food to maintain a youthful appearance forever.
