Your diet affects how you feel and how well your body functions.

While a nutrient-dense, well-rounded diet supports your immune system, a diet that’s low in nutrients and high in ultra-processed foods impairs immune function (1Trusted Source, 2Trusted Source).

There’s no doubt that limiting how much added sugar you consume promotes your overall health and immune function.
