Milk also contains retinol, a known anti-aging and skin-restoring antioxidant. Plus, milk's vitamin D is also an anti-aging vitamin thanks to its anti-inflammatory effects and protection from UV rays.
Milk may help slow aging
The proteins found naturally occurring in milk help boost the elasticity of our skin so we get fewer wrinkles, and they develop slower. Milk also contains retinol (an antioxidant) and vitamin D which can help protect our skin from damaging sun rays.
Your bone health might improve
Not only is milk a great vegetarian protein source, but it's also packed with calcium and vitamin D—two nutrients that are vital for bone health. Calcium is a mineral needed to build and maintain strong bones, and vitamin D helps our body absorb calcium from the foods we eat.
Milk has long been seen as an important source of calcium and other nutrients, particularly for children. But some researchers suggest that it is not a necessary part of a healthy diet for most adults, and may even be harmful if consumed excessively.
Excessive intake of anything is harmful even if it is something as healthy as milk. As per a Swedish study, drinking too much milk in a day can be linked with mortality and increased risk of fracture. For researchers, too much milk meant three or more than three glasses a day.
“The protein found in dairy products can help promote skin elasticity as we age,” says Dr. Beall. Milk also contains retinol, a known anti-aging and skin-restoring antioxidant. Plus, milk's vitamin D is also an anti-aging vitamin thanks to its anti-inflammatory effects and protection from UV rays.
Like meat, dairy is high in certain proteins essential for collagen stimulation. Certain dairy products contain both the amino acids lysine and proline, which both help to form collagen.
Exposure to light is a top cause of premature aging: Sun exposure causes many skin problems. Ultraviolet (UV) light and exposure to sunlight age your skin more quickly than it would age naturally. The result is called photoaging, and it's responsible for 90% of visible changes to your skin.
As a plastic surgeon sees it, there are structural reasons that people age differently. “Asians have a wider bone structure than a typical Caucasian face,” Dobryansky notes. “The soft-tissue loss is seen and felt to a lesser extent because of the wider structure.
A diet full of protein-rich foods, whether from plant or animal sources, can help supply these critical amino acids. Other nutrients that aid the process of collagen production include zinc, vitamin C, and copper. So, fruits and vegetables high in vitamins and minerals are also a friend to supple skin.
Citrus fruits like oranges, lemons, limes, and grapefruit are known for being foods high in collagen-producing properties.
Ultraviolet rays, aka sunlight, cause collagen to break down faster. With sun exposure, those UV rays damage the skin by entering the dermis (the second and thickest layer of our skin) which causes collagen to break down faster.
Eggs don't contain fully synthesized collagen; however, egg whites are a rich source of proline, one of the two amino acids needed to synthesize collagen in the human body. They also contain some glycine. Pair eggs with foods high in vitamin C, copper, and zinc.
Eating foods rich in vitamin C and amino acids can increase the levels of hyaluronic acid and collagen in the body as both are important for skin. Foods such as oranges, red peppers, kale, Brussels sprouts, broccoli, and strawberries are all rich in vitamin C.
Exposure to ultraviolet (UV) light.
Ultraviolet radiation, which speeds the natural aging process, is the primary cause of early wrinkling. Exposure to UV light breaks down your skin's connective tissue — collagen and elastin fibers, which lie in the deeper layer of skin (dermis).
Wrinkles, age spots and small growths called skin tags are more common.
