Each of the cubes in the image represents one teaspoon of sugar. To figure out how much sugar is in your food/drink, look at the nutrition facts and divide the number of grams of sugar by 4. This gives the number of teaspoons, PER SERVING. For example, if a product has 12g of sugar per serving, that equals 3 teaspoons.
You'd be surprised how much sugar is added in processed foods. The nutrition facts for Kashi's "Heart to Heart" instant oatmeal in raisin-spice flavor lists 16g of sugar. That's 4 teaspoons of sugar per bowl! Way more than you would add yourself if you started with plain oats and made your own bowl of oatmeal from scratch. I don't even add sugar to mine. The dried fruit, cinnamon, and sliced almonds add plenty of flavor.
Another shocker: Yoplait Original Strawberry Yogurt has 26 grams of sugar! In one tiny cup, it packs 6.5 teaspoons of sugar. That's like half the container! You are much better off starting with plain yogurt and adding the sugar yourself. When you sweeten things yourself, you'll realize that you don't need to add that much sugar.
Another conversion you can use is grams to calories. Each gram of sugar contains 4 calories. 26 x 4 = 104. So 104 out of the 170 calories per Yoplait yogurt comes from sugar!
I'm not advocating artificial sweeteners to cut down on sugar. Nor am I against occasional desserts. Just be aware that unexpected foods can contain a lot of sugar. Be aware of how much sugar you're eating, and try to minimize it, naturally.
