In this article Tribune online examines seven scientifically supported benefits:
1. Rich plant-based protein
Peanuts provide a significant amount of plant protein.
According to USDA figures, 100 g of raw peanuts yield about 25.8 g protein, making them one of the highest protein nuts/legumes per weight. This helps in muscle repair, satiety, and supporting metabolic functions.
2. Heart health and lowering cholesterol
The healthy fats (monounsaturated and polyunsaturated) in peanuts, along with phytosterols, help reduce LDL (‘bad’) cholesterol absorption.
Epidemiological studies have linked regular nut and peanut intake with reduced risk of cardiovascular disease.
3. Antioxidant and anti-inflammatory effects
Peanuts contain bioactive compounds such as resveratrol, flavonoids, phenolic acids, and CoQ10, which help neutralize free radicals and reduce oxidative stress.
By lowering inflammation, they may help protect against chronic diseases.
4. Better blood sugar regulation
Because peanuts are high in healthy fat, protein and fiber but relatively low in digestible carbs, they lead to a gentler blood sugar response.
Some trials and reviews suggest peanuts and tree nuts improve insulin sensitivity and reduce post-meal glucose spikes.
5. Assists with weight management
Although calorie-dense, moderate consumption of peanuts does not necessarily lead to weight gain.
In fact, their combination of protein, fiber, and healthy fats can promote satiety (feeling full) and reduce overall calorie intake.
Some observational studies show that peanut eaters tend to have lower body mass index when controlled for other factors.
6. Micronutrients and essential vitamins
Peanuts are a good source of several vitamins and minerals: vitamin E, magnesium, phosphorus, niacin (vitamin B3), folate, copper, manganese, and zinc.
These support many body systems (e.g., immune, nerve, enzyme reactions).
7. Longevity and reduced mortality risk
Large cohorts and meta-analyses suggest regular consumption of nuts (including peanuts) is associated with lower all-cause mortality, particularly from cardiovascular causes.
While causation isn’t proven, these associations reinforce peanuts’ role in a healthful diet.
Peanuts (and peanut products) may be contaminated by aflatoxins, a toxin from mold, especially in hot, humid storage conditions. It’s safer to source peanuts from reputable suppliers and store them properly.
