Eating peanuts or any other nut is good for you, but added salt is not good for people with high blood pressure. For healthy individuals, 2,300 milligrams of salt intake daily is recommended. For those over 50 years of age or who have hypertension, the recommendation drops to 1,500 milligrams.
A 1-ounce serving of roasted peanuts provides omega-6 fatty acids, essential for brain function, bone hardiness and a healthy reproductive system. In addition, one serving of peanuts supplies 14 grams of heart-healthy unsaturated fat, plus selenium, thiamin, copper, riboflavin, zinc, vitamin B-6, potassium, pantothenic acid, iron and calcium, nutrients that collectively support cellular metabolism.
Eating about 35 peanuts as a snack helps curb hunger between meals and discourages overeating at mealtime. A recommended snack size for any type of food is 100 to 200 calories. In larger quantities, peanuts and peanut butter are beneficial to individuals who want to gain weight, because peanuts are high in protein, fiber and good fats, and they add nutritious calories. Nuts are energy dense and should be eaten in moderation. However, they are a more nutritious choice than energy-dense foods that are high in calories and low in nutritional value, such as potato chips and french fries.
