Collagen is an important protein in the body, accounting for about 30% of total protein, playing a major role in maintaining the structure and elasticity of skin, bones, muscles, blood vessels and connective tissues. When the body lacks collagen, it can lead to aging of the skin, joints and other health problems.
Guava is one of the fruits rich in natural vitamin C, an essential element that helps stimulate collagen synthesis in the body. Vitamin C is directly involved in the hydroxylation of proline and lysine, two important amino acids in the structure of collagen. According to research by the United States Institute of Nutrition (USDA), 100g of guava can provide up to 228mg of vitamin C, 5 times more than oranges, making it an outstanding source of vitamin C. Consuming vitamin C not only helps the body produce collagen more effectively but also helps protect collagen from degradation by oxidants.
Vitamin C plays an important role in improving skin elasticity and reducing the appearance of wrinkles, signs of aging. When combined with other nutrients found in guava such as vitamin A, flavonoids, and antioxidants, guava not only helps promote collagen synthesis but also protects existing collagen from damage from the external environment, including UV rays and pollution.
In addition to vitamin C, guava also contains a large amount of minerals such as potassium and magnesium, which help maintain skin health, increase skin firmness and elasticity. Studies by health organizations such as the World Health Organization have shown a link between a diet rich in antioxidants and the reduction of signs of aging, in which guava is a very good choice.
