Another nut to make this list is a tasty cashew. These nuts can be found in many nut mixes and make great snacking foods as well. Cashews are loaded with healthy omega-3 fats similar to what almonds offer. In addition, since cashews are in the nut group, they are also low on the glycemic index, at only about 20. Consuming whole cashews can be a great way to curb your blood glucose levels, but also a good way to add omega-rich fatty acids to your diet. Consider consuming more of these nuts to improve your overall heart and metabolic health.
