Almond butter is also a great source of vitamin E, magnesium, copper, vitamin B2 (riboflavin), and phosphorous. It is a great source of monounsaturated fat, protein, and fiber which are essential for heart health. An almond enriched low calorie diet may also help you lose weight more effectively than a low calorie diet high in complex carbohydrates. The addition of almonds to the diet has been found to lead to a slimmer waist line and lower body fat levels than those on a low calorie/high carbohydrate diet.
