Raw almonds contain about 7 calories per nut, meaning a single serving of raw almonds, which is equal to 1/4 cup, or about 23 almonds, is about 160 calories. This serving size of raw almonds can be measured with a standard 1/4 cup measure or estimated as a small handful. It may also be helpful for those people who are watching calories, but do not have easy access to a 1/4 cup measuring cup to measure a serving of raw almonds as a full shot glass, a small baby food jar, a small spice jar or enough to cover a 3-inch-by-3-inch sticky note.
In addition to containing about 160 calories, a 1/4 cup, or 1 dry ounce, serving of raw almond kernels also contains about 6 grams of protein and 3.5 grams of dietary fiber. Because most raw almonds are unsalted, a full serving has a negligible amount of sodium, and these healthy kernels also pack some healthy nutrients, including calcium and potassium. A serving of almonds is relatively high in fat, at about 14 grams of fat per 1-ounce serving, about .6 grams per kernel, but the fats contained in raw almonds are heart-healthy monounsaturated fat, which are considered to be "good" fats.
