Blueberries

Packed with antioxidants, blueberries provide both flavor and nutrition. As reported by My Food Data, a one-cup serving has just 84 calories and 3.6 grams of fiber. It also provides 16% of the recommended daily intake of vitamin C, 24% of vitamin K, and 22% of the recommended. These tiny fruits are also rich in phenolic acids, quercetin, anthocyanidins, and other compounds with antioxidant activity. The question is what happens when you eat too many blueberries?

Most fruits, including blueberries, are relatively high in fiber. When consumed in excess, this nutrient can cause bloating, diarrhea, and mineral deficiencies. In general, women should not exceed 25 grams of fiber per day. On the other hand, men should consume about 38 grams per day. While it's unlikely to get too much fiber from blueberries alone, you may feel bloated after eating three or four cups of berries, especially if you increase your fiber intake too quickly. Even the healthiest foods can be harmful when consumed in large amounts. Blueberries are no exception.

Eating blueberries every day can make it easier to get more vitamins, minerals, and antioxidants into your diet — just make sure you don't go overboard. These dark-colored fruits boast over 21 grams of carbs, including 14.7 grams of sugar, per cup (via My Food Data). The same amount of strawberries, by comparison, contains 11 grams of carbs — including 7 grams of sugar in the form of fructose. Watermelon, oranges, and other fruits are much lower in sugar than blueberries, too. If you eat three cups of blueberries per day, you'll get nearly 65 grams of carbs and 44 grams of sugars. This could lead to weight gain and hyperglycemia in the long run.
