Almonds are booming with popularity among people with peanut allergies and people who have a plant based diet. Almond butter is a thing now (as well as every other nut turned into a butter) and many times you can find almonds used in meat or cheese substitutes. Almonds are among the lowest-calorie nuts. They are also a great source of calcium, heart-healthy monounsaturated fats, protein, and fiber. The health benefits of almonds are extensive, and range from aiding in relief from anemia to relief from skin disorders.
