How Many Almonds Is 100 Calories?

Almonds provide healthy fat, fiber and protein, making them a good snack option. Researchers examined the health effects of consuming almonds with meals or as snacks and published the results in the October 2013 edition of the "European Journal of Clinical Nutrition." The study found consuming almonds resulted in reduced hunger and lower post-meal glucose levels without causing weight gain. Portion control plays a crucial role in managing your calorie intake. A 100-calorie portion is a good size for snacking.

Nut Gets a Recount

Researchers from the U.S. Department of Agriculture found that almonds contain 20 percent fewer calories than originally thought. The researchers examined the energy content of almonds using an updated method of measuring calories in food. The team found that while scientists once thought that a 1-ounce serving of almonds contained roughly 168 calories, it actually provides closer to 129 calories. A 1-ounce serving is about 23 almonds. This data means that a 100-calorie serving is equivalent to about 19 almonds. The results were published in the August 2012 issue of the "American Journal of Clinical Nutrition."
