1. Unintended Weight Gain
If you sit down with a bag of grapes and turn on the TV, before you know it, you could eat most of the bag. Suddenly, your 62-calorie snack can multiply, eventually giving you the same number of calories you’d get if you ate a small meal.
If you eat large portions of grapes on a regular basis without first measuring your portion size, the additional calories may cause you to gain unintended weight.
2. Carb Overload
That’s 900 to 1,300 calories from carbs, or 225 to 325 grams (g) daily, based on a 2,000-calorie diet. That 1-cup serving of grapes has about 16 g of carbs. If you’re snacking on grapes freely and not paying attention to your serving size, you could quickly consume more than your daily carb allotment.
3. Gut-Related Concerns
Grapes offer some fiber — roughly 1 g from 1 cup. That’s probably not enough to cause any disruption in your gut. If you snack on a larger serving of grapes, however, you increase your fiber intake.
4. Allergy Attack
An allergic reaction doesn’t necessarily mean you’re allergic to the fruit itself. You may be allergic to a pesticide on the grapes, or to the yeast or mold that grows on the grapes.
The only way to be certain of what you’re allergic to is to undergo allergen testing at your doctor’s office or via a referral to a testing center. So if you’re experiencing symptoms after eating grapes, your best bet is to check in with a doctor for proper testing before you consume more grapes.
