Superfoods That Fight Colds
Boost your immunity
They say you are what you eat, so it makes sense that eating healthy foods can help you stay, er, healthy.
“You can’t underestimate the importance of good nutrition when it comes to…your immune system,” says Karen Ansel, RD, a spokesperson for the Academy of Nutrition and Dietetics. “Vitamins, minerals, antioxidants—these are what keeps your body strong, and without them you’re not giving your body the edge it needs to ward off infection.”
And we’re not talking just fruits and vegetables: Foods from every food group are represented here. Make them a part of your diet for your best defense against colds and flu.
Oily fish—including salmon, tuna, and mackerel—are rich in omega-3 fatty acids, compounds that help reduce harmful inflammation in the body. Chronic inflammation prevents your immune system from working properly, and can contribute to colds and flu as well as more serious diseases.
Omega 3s may fight colds on more than one front. In a placebo-controlled 2011 study published in Brain, Behavior and Immunity, medical students who took fish oil supplements for three months had lower inflammation levels and also fewer symptoms of anxiety—a condition that can itself weaken immune function.
