Sip This for a Stronger Immune System

Cellular Soldiers
Researchers think the polyphenols in grape juice should probably take the credit for the immune-boosting effects in the study. But keep in mind that the levels consumed in the study do have some drawbacks. A cup and a half of grape juice adds over 250 calories and 60 grams of sugar to a person's day. So to keep your overall calorie intake from inching up, use the juice in place of high-calorie, low-nutrition items currently in your diet. Or just sip the occasional glass of grape juice to help boost your body levels of polyphenols a bit. And practice a well-rounded variety of other immune-boosting habits, such as exercising regularly, getting adequate sleep, and reducing stress.
