The focus of this post will be on the health benefits of some of the most commonly consumed nuts including almonds, cashews, peanuts, pecans, pistachios, and walnuts. Nuts are a great source of protein, fiber, vitamins,  minerals, and essential fats. Everyone can benefit from eating nuts, but especially those of you who are eliminating meat and dairy from your diets. Of course not all nuts have the same nutritional profile, and this will be something we delve into, hopefully providing you some guidance or at least an understanding of the differences between these commonly consumed nuts. Let’s look at each of these nuts for their overall benefits and nutritional data:

While there are differences in the nutrients derived from these nuts, there is also a many similarities and they all provide a healthy dose of potassium and phosphorus, generous amounts of protein, the good kind of fat, and much needed fiber. So instead of reaching for that bag of chips or bowl of ice cream, grab a handful of cashews, almonds, pecans, pistachios, walnuts, or peanuts. You will feel so much better about what you are putting in your body, and you will find nuts are both a delicious and satisfying treat.

Munch on my friends.
