Virus season is right around the corner, and ensuring you’re getting enough of the nutrients responsible for immune health is important for reducing your risk of picking up infections, explains Julia Zumpano, RD, Registered Dietician at the Cleveland Clinic Center for Human Nutrition. Recent research published in Nutrients shows that even if you catch a respiratory virus like Covid this season, maintaining good nutrition may reduce your symptoms.
In general, getting your nutrients from food is ideal. But realistically, “most Americans do not meet their needs through food,” she says. “The Standard American Diet (SAD) is inadequate in nutrition due to high intake of processed, low-nutrient foods.” In fact, less than 15% of Americans meet daily fruit and vegetable recommendations, according to Ali Bandier, MS, RD, a registered dietitian from New York.
So, while shifting to a whole, nutrient-dense food diet is the best way to ensure you’re getting your immune-boosting vitamins, supplements can help fill gaps as we head into cold and flu season. Elderly people, vegans, vegetarians, those with blood tests that indicate a deficiency, or those who practice strict dietary restrictions (such as low-calorie, keto, or dairy-free) can benefit from supplementation as well, says Zumpano.
