Eating salty food is bad for your skin - VnExpress Health

Eating foods high in salt can cause skin problems such as peeling, acne, puffy eyes and premature aging.

Sodium is an important nutrient in the diet. However, consuming too much sodium can affect health such as high blood pressure, edema, bloating, dehydration, dry skin, aging. Below are the risks to the skin if you eat too much salt (sodium chloride).

Dry, flaky skin

Consuming large amounts of sodium reduces the amount of water your internal organs absorb. This causes your body to pull water from your cells and skin, leading to dehydration. Over time, your skin becomes dry and flaky.

Increased sebum secretion

Salty foods not only dehydrate you, but also cause your skin to produce more oil to keep it hydrated. Oily skin increases the risk of clogged pores, causing inflammation and leading to blackheads, whiteheads, and pimples.

Itchy skin

Foods high in salt often stimulate the peripheral nervous system, causing skin damage that causes itching and discomfort. Therefore, people with eczema should limit their salt intake. According to a 2019 study published by the University of Munich, Germany, the sodium content in salt can promote immune responses associated with atopic dermatitis.

Premature aging

A high-salt diet can accelerate aging. Consuming foods fried in oil at high temperatures also releases free radicals, which can damage DNA and accelerate aging.

A 2023 study from the US National Heart, Lung, and Blood Institute found that blood sodium levels above a certain threshold accelerate aging, increase the risk of chronic disease, and premature death. The data analyzed more than 15,000 people, ages 45-66, over 25 years.

Puffy eyes

Salt causes the body to retain water, which leads to puffiness because the area around the eyes is very thin and sensitive. When you consume salty foods, your body retains more water to balance out the excess salt, causing swelling.

To protect your skin, limit the use of salt to season food, use herbal spices instead. Avoid eating processed foods because they are often high in sodium.
