Do you know what 100 calories looks like? Hi, I'm Susan Bowerman, Registered Dietician and today we're going to look at 100 calorie portions of different foods. 

What makes a food high or low in calories? High fat foods have a lot of calories per bite, while watery foods, like vegetables, have the fewest, which may help you see why some foods rack up calories so fast, and why 100 calories' worth of healthy fruits and veggies can be so filling.

We're going to start at this end of the table and move from the smallest servings over to the largest. Oil is pure fat, which is why you only get 2 teaspoons for 100 calories. Mayonnaise and butter each contain a bit of water, so the calories get slightly diluted, but 100 calories still only buys you 1 tablespoon of butter of mayonnaise.

Nut butters are pretty rich, too for 100 calories you also only get about 1 Tablespoon. Most cheese is high in fat, so for 100 calories you get barely a bite. Sugar in any form white, brown, honey, maple syrup, and agave can add up quickly if you don't use it sparingly. For 100 calories, you get about 2 tablespoons of any of these sugars.

Your typical cookie gives you a dose of fat and sugar, which is why the calories can add up before you know it. Just two little cookies have 100 calories. If chips are your thing, know that the average potato chip has about 10 calories. That means that just 10 chips will cost you 100 calories and most people eat a lot more than that at a sitting.

An average slice of whole grain bread is about 100 calories, which isn't bad, considering the vitamins, minerals and fiber you'll be picking up. But a bagel is heavy and dense. A typical bagel is equivalent to about 4 slices of bread, which is why for 100 calories you can only eat about ¼ of this bagel.

Moving on to proteins, the amount of fat they contain makes a big difference in calories. 100 calories of steak is just a few bites, but for the same calories you get a larger amount of turkey since it's so low in fat. Most fish is very low in fat, too, which is why you get 20 large shrimp for 100 calories.

Fruits and vegetables are generally your best calorie bargains, since they're full of calorie-free water and fiber. But dried fruits can add up quickly since they've had most of the water removed. 100 calories' worth of raisins is only ¼ cup, which is why you get 4 times the amount when you eat them as fresh grapes.

Since they naturally contain sugar, 100 calorie servings of fruit are a little smaller than 100 calorie servings of vegetables, but they're still a bargain. For 100 calories, you can eat 1 ½ grapefruit, 2 cups of strawberries, or a large apple.

But vegetables are where you really get the most for your calories. Since they're full of water and fiber, look at what you can get. For 100 calories, you can eat 2 stalks of broccoli, 3 cucumbers, 4 carrots or two entire heads of lettuce!
