Aging & Gerontology

Healthy food and healthy lifestyle lead to healthy aging. It helps in increasing the lifespan of humans. Intake of proper nutrients in diet helps us in attaining a better life at each stage of life. It has been found that people over the age of 65 years of age are either under-nourished or over- nourished. Nutrition Level. Nutrition is closely associated with skin health and is required for all biological processes of skin from youth to aging or disease. Nutrition levels and eating habits can repair damaged skin and can also cause damage to the skin. Choose a variety of nutrient-dense foods across and within all the food groups: vegetables, fruits, grains, protein foods, dairy products, and oils.

Including enough quality protein sources in your diet strengthens your collagen levels and therefore makes your skin firmer and less prone to wrinkles. Including enough quality protein sources in your diet strengthens your collagen levels and therefore makes your skin firmer and less prone to wrinkles. Simple dietary changes and adopting lifestyle alterations, including improved sleep schedules, taking probiotics, and exercising, can reduce signs of biological aging by three years in just eight weeks, a new study report. For example, Irina Conboy's lab at the University of California, Berkeley has been studying a protein called TGF-beta, which contributes to aging.

Cysteine is a non-essential amino acid. Total cysteine (including reduced cysteine and oxidized cystine) and the cystine to cysteine ratio in human plasma were shown to increase with aging, while the levels of some amino acids were shown to decline. They stimulate collagen production amino acids for skin tightening. Collagen is a protein responsible for your skin's firmness and elasticity. As we age, our skin produces less collagen, leading to sagging and wrinkling. Amino acids have been found to boost your skin's natural production of collagen and elastin. Isoleucine is important in repair of tissue. It promotes the natural production of anti-microbial peptides. Leucine, in conjunction with glycine and proline, improves fine lines and wrinkles. Lysine helps make skin firm by reinforcing its supportive elements.

Animal-based foods (meat, poultry, fish, eggs, and dairy foods) tend to be good sources of complete protein, while plant-based foods (fruits, vegetables, grains, nuts, and seeds) often lack one or more essential amino acid. The protein in spinach contains all essential amino acids. One cup of spinach contains 121 mcg of vitamin K, which is just over 100% of a person's daily needs. Spinach is also a rich source of folate, vitamin A, and vitamin C. It is a good source of magnesium, iron, and potassium, and a decent source of calcium. Broccoli, like most other vegetables, doesn't contain enough of each of those acids, so it's referred to as an “incomplete” protein. Examples of complete proteins include meat, poultry, fish and dairy products.
