Air pollutants, seasons, and mood fluctuations are uncontrollable issues that can have a harmful impact on the skin. But one thing you can control is the food you eat. It is no secret that collagen and antioxidant-rich foods are good for the skin, but not many know the kind of foods that can ruin the skin. Here are some foods that you should avoid or limit to have healthy, glowing skin. Fried foods Deep-fried food items like french fries are cooked in refined vegetable oils such as canola, safflower, and peanut oils. While they seem healthy, these oils are loaded with trans-fat. This can cause inflammation, resulting in premature wrinkles and aged-looking skin. Processed meat Processed meats like bacon and brined chicken contain high levels of sodium. Excess consumption of sodium can lead to water retention in the body and cause puffy and swollen skin. Sodium nitrate is added to many processed foods that destroy collagen and cause premature aging. Doughnut Doughnuts are delicious and tempting, but it’s best to restrict their consumption. Such deep-fried and baked goods contain a high amount of sugar, which is probably linked to the development of wrinkles. Doughnuts also contain processed carbs that can damage the skin’s collagen and make it springy.
