On the flip side, grapes are about 82% water, which is great for hydration. They also have a modest amount of fiber, especially if you eat the skins (which you should—don’t be a grape-peel-phobe).
Here’s the ironic part: too many grapes can actually backfire. That same fiber, combined with the natural sugar (fructose), can cause bloating, gas, and even diarrhea if you overdo it. Basically, you’ll be making friends with your toilet on a first-name basis.
So, if you’re planning a grape binge before a big meeting or date night… maybe don’t. Unless your goal is to audition for a human juice fountain.
