Most people consider drinking juice to be a healthy alternative to drinking sugary sodas. Therefore, it often comes as a surprise when they discover that, although fruit juice contains important vitamins, it’s also chock full of natural sugar (called fructose) and usually contains as many calories as the soda. An eight-ounce (1 cup) serving of 100% orange juice contains approximately 110 calories. To reduce the calorie impact while still enjoying the taste and nutritional benefits of juice, try mixing 4 ounces of juice with 4 ounces of water, or a mixture of 3 ounces of juice and 5 ounces of calorie-free sparkling mineral water or seltzer. This can reduce your calorie intake by almost 500 calories a week, or half a pound per month.
