Looking for ways to reduce stress? Many healthy foods offer a subtle side effect – they help reduce stress. Carolyn Snyder is a registered dietitian at Cleveland Clinic. A German study found vitamin C can help reduce stress and return blood pressure to normal levels, so foods like oranges are stress busters. Avocados are packed with potassium, which helps lower blood pressure, and pistachios and walnuts can have the same effect. Foods high in omega-3 fatty acids, like salmon, help keep stress hormones at bay as well. And Snyder says to try some Thanksgiving dinner if you’re feeling stressed. The tryptophan in the turkey is soothing, and sweet potatoes offer benefits too.
