  • Peanut butter offers healthy fats, protein, and key nutrients.
  • Moderate intake supports heart, muscle, and brain health.
  • Natural peanut butter is best; avoid added sugar and salt.

Peanut butter is a delicious and versatile spread found in sandwiches or snacks. But nutritionists say this easy-to-prepare food carries an influential combination of nutrients that can benefit the body. Peanut butter is made mainly from ground peanuts and is a great source of healthy fats, plant-based protein, vitamins and necessary minerals that help support many body functions.

Peanut butter is not consumed by many due to its calorie content. But health experts say that moderation is key, and peanut butter consumed in small portions can be a healthy part of a well-balanced diet. A single spoonful gives energy, helps with muscle health and delivers nutrients that help maintain overall wellbeing.

Peanuts themselves are rich in healthful monounsaturated fat, like the type found in nuts and seeds that are often linked with cardiovascular benefits. Protein and fiber from these fats keep the body charged up for longer and prevent hunger pangs.

Dr Radhika Mehta, Senior Clinical Nutrition Specialist with Felix global based out of Delhi stated that peanut butter is a healthy snacking option if eaten in controlled quantities. “A tablespoon of peanut butter provides healthy fats, protein and essential micronutrients that tame energy levels, support heart health and maintain muscle function. The trick is to opt for the natural versions without added sugars or too much salt,” she says.
