 This is why you should not drink orange juice in the morning or ever. For starters, orange juice is extremely high in calories and loaded with sugar. Did you know a 12 ounce glass of orange juice contains 170 calories and 34 grams of sugar? That's almost the exact amount of sugar that's in a 12 ounce coke of the same size. Now I know what you're thinking, what about all that vitamin C you did in orange juice? Yes, orange juice does have 100% of your daily value of vitamin C, but it's at the expense of all that sugar. If it's vitamin C that you seek, just eat a balanced diet. Get your vitamin C from kale or broccoli or even a multivitamin if you want to. The point I'm trying to make here is that the negatives of orange juice outweigh the benefits of it. Treat yourself every now and then, but don't have it every single day. Cheers.
