2. Eat Seaweed
Seaweed is a big part of the Japanese diet, and not surprisingly, it contains a lot of benefits for skin. The wealth of vitamins and minerals found in seaweed, including calcium, magnesium, vitamin K, iron, and folate, make it a particularly effective addition to a balanced diet.
Regular seaweed consumption is thought to protect skin from sun damage like age spots. It also contains certain anti-inflammatory components that can reduce swelling and redness. Its iodine content further rejuvenates the skin and helps to regulate metabolism.
