In short, no. Fruit does contain sugar, but it comes in a healthy package along with vitamins, minerals, antioxidants, fiber and water. The fruit in sugar is not considered a health concern according to the 2015-2020 Dietary Guidelines for Americans.
How much fruit should I have?
The recommended amount of fruit for a 2,000-calorie diet is about two cups a day, according to the 2015 Dietary Guidelines. Nearly 80% of the American population doesn’t meet that recommendation.
Unless you’re a fruitarian, I wouldn’t worry about eating too much fruit (it’s not usually the root cause of weight gain or ill health). Instead, limit the amount of added sugar in your diet. Strong evidence suggests that added sugar is associated with an increased risk of obesity, type 2 diabetes, and cancer.
Is juicing as good (or better) than eating fruit?
Juicing is not always a super-healthy option. Many juicers filter out heart-healthy, blood sugar-stabilizing fiber. The sweet liquid you drink does have some vitamins and minerals, but you lose a lot of nutrients when the skin and fiber are left behind with the pulp. Plus, you eat more slowly when you chew, giving your stomach a chance to send the ‘all full’ signal to your brain, and slowing the onslaught of blood sugar. You may end up consuming more calories and raising your blood sugar levels more dramatically when you chug—rather than chew—your meal.
If you’re going to drink fruit, I recommend blending the whole fruit instead of extruding the juice. Add a source of fat and protein to keep you full (like nuts, nut butter, seeds, yogurt, tofu, or protein powder).
