Signs of zinc deficiency include acne, eczema, slow wound healing, and dry, scaly skin. In severe cases, it can lead to hair loss and immune dysfunction.
5.3 How can I add more zinc to my diet?
Eat more zinc-rich foods, such as oysters, beef, pumpkin seeds, and lentils. Consider taking a zinc supplement if you are concerned about deficiency.
6. Incorporate Healthy Fats for Skin Elasticity
Certain fats act as a natural moisturizer, keeping skin supple and improving elasticity. These include monounsaturated and polyunsaturated fats found in avocados, oily fish, nuts, and seeds. These fats are often packaged with vitamin E. According to a study in the American Journal of Clinical Nutrition, omega-3 fatty acids can reduce inflammation and improve skin conditions like eczema.
Pay special attention to omega-3 fatty acids, which are anti-inflammatory and may alleviate skin conditions like eczema and psoriasis. They are found in oily fish such as salmon, trout, and sardines, as well as plant sources like flaxseed, chia seeds, walnuts, and rapeseed oil.
