You might want to do that. Here’s why: Eating foods rich in omega-3 fatty acids helps to reduce skin inflammation and balance your skin’s pH level. Research has also shown this type of healthy fat helps to relieve depression and stabilize your moods. So if your skin—or your brain—has been feeling or looking stressed, try adding some omega-3-rich foods to your day—walnuts, chia seeds. Salmon and mackerel are also terrific sources too. What you eat will affect how your skin looks and how you feel. It’s a simple truth that often gets lost in the noise.
