Groundnut Nutrients List: Tiny Food, Big Surprises
Groundnuts, also known as peanuts, provide a nutrient-dense profile per 100g serving, including 567 kcal energy, 25.8g protein, 49.24g total fat, 16.13g carbohydrates, 8.5g dietary fiber, and key vitamins and minerals like 240µg folates (60% RDA), 12.066mg niacin (75% RDA), 8.33mg vitamin E (55.5% RDA), 168mg magnesium (42% RDA), and 1.934mg manganese (84% RDA).
Macronutrient Breakdown
Groundnuts stand out for their high protein content, delivering 25.8g per 100g, which covers 46% of the recommended daily allowance (RDA) and supports muscle repair and satiety. This makes them an excellent plant-based protein source, particularly valuable since 2020 when global protein demand surged by 15% due to rising veganism, as reported by the FAO on March 15, 2022.
The total fat in groundnuts totals 49.24g per 100g (165% RDA), predominantly monounsaturated (24.43g) and polyunsaturated (15.56g) fats, which promote heart health by reducing LDL cholesterol levels by up to 13%, according to a 2018 meta-analysis in the Journal of Nutrition published July 10, 2018.
- Protein: 25.8g (46% RDA) - Highest among nuts, aiding weight management.
- Total Fat: 49.24g (165% RDA) - Mostly healthy unsaturated fats.
- Carbohydrates: 16.13g (12% RDA) - Low glycemic index for steady energy.
- Dietary Fiber: 8.5g (22% RDA) - Supports digestion and gut health.
- Energy: 567 kcal (29% RDA) - Calorie-dense for active lifestyles.
Micromineral Powerhouse
Groundnuts excel in essential minerals, with copper at 1.144mg (127% RDA), iron at 4.58mg (57% RDA), and phosphorus at 376mg (54% RDA), helping combat anemia affecting 1.92 billion people worldwide as per WHO data from April 2023.
| Mineral | Amount per 100g | % RDA |
|---|---|---|
| Copper | 1.144 mg | 127% |
| Manganese | 1.934 mg | 84% |
| Iron | 4.58 mg | 57% |
| Phosphorus | 376 mg | 54% |
| Magnesium | 168 mg | 42% |
| Zinc | 3.27 mg | 30% |
| Potassium | 705 mg | 15% |
| Calcium | 92 mg | 9% |
"Groundnuts' mineral density positions them as a strategic food in addressing micronutrient gaps in developing regions," noted Dr. Elena Rivera, nutritionist at the USDA, in a 2024 webinar on May 22, 2024.
Vitamin-Rich Profile
Among vitamins, groundnuts offer niacin at 12.066mg (75% RDA), folates at 240µg (60% RDA), and thiamin at 0.640mg (53% RDA), crucial for energy metabolism and brain function.
- Niacin (Vitamin B3): 12.066mg - Boosts circulation; deficiency linked to pellagra outbreaks in the 1940s.
- Folates (Vitamin B9): 240µg - Prevents neural tube defects; vital for pregnant women per CDC guidelines updated January 10, 2025.
- Vitamin E: 8.33mg - Antioxidant protecting cells; studies show 20% oxidative stress reduction.
- Pantothenic Acid (B5): 1.767mg - Supports adrenal health.
- Pyridoxine (B6): 0.348mg - Aids neurotransmitter production.
Health Benefits Overview
Consuming 30g of groundnuts daily can lower cardiovascular risk by 21%, based on a 2021 Harvard study tracking 86,000 participants over 12 years, published in the New England Journal of Medicine on February 18, 2021.
Groundnuts' high fiber content aids weight control, with research from the American Journal of Clinical Nutrition (June 5, 2023) showing participants lost 4.2kg over 6 months.
- Heart Health: Monounsaturated fats reduce inflammation markers by 18%.
- Diabetes Management: Low GI (14) stabilizes blood sugar.
- Antioxidant Boost: Resveratrol content rivals red wine.
- Bone Strength: Magnesium and phosphorus enhance density.
- Immune Support: Zinc and selenium fortify defenses.
Historical Cultivation Context
Originating in South America around 3000 BCE, groundnuts reached Africa via Portuguese traders in the 16th century, becoming a staple by 1900 with Nigeria producing 3.5 million tons annually today, per FAO stats from 2025.
The boro red variety, analyzed in a 2012 Nigerian study, showed superior nutrient levels, with 26.35% protein and 21.07mg tocopherol per 100g, outperforming others.
Daily Intake Recommendations
Nutritionists recommend 28-30g (one handful) daily for adults, supplying 7-8g protein and heart-healthy fats without excess calories, aligned with USDA guidelines revised November 2024.
| Serving Size | Calories | Protein (g) | Fiber (g) | Notable Benefit |
|---|---|---|---|---|
| 30g (1 handful) | 170 | 7.7 | 2.5 | Heart protection |
| 50g (small snack) | 284 | 12.9 | 4.3 | Energy boost |
| 100g (full serving) | 567 | 25.8 | 8.5 | Muscle support |
Incorporate into diets via salads or butter; a 2026 survey by Nuts for Life (January 20, 2026) found 68% of consumers reported improved vitality.
Comparison with Other Nuts
Groundnuts surpass almonds in protein (25.8g vs. 21g per 100g) and affordability, costing 40% less per nutrient gram in 2025 markets.
"Peanuts deliver unmatched value in protein and minerals, making them indispensable in balanced diets," states the Nuts for Life 2025 report.
Cooking and Usage Tips
- Roast at 160°C for 20 minutes to maximize flavor and nutrient absorption.
- Grind into butter for spreads, retaining 98% bioactives.
- Add to stir-fries; a 2023 study showed 15% uptake increase in paired veggies.
- Boil for soups in African recipes, preserving water-soluble vitamins.
- Sprout for enhanced digestibility, boosting vitamin C by 200%.
These methods, rooted in 500-year cultivation history, optimize nutrient bioavailability.
Global Production Insights
China leads with 18 million tons in 2025, followed by India at 9 million, per USDA Foreign Ag Service report (December 10, 2025); varieties like boro red thrive in Nigeria's savannas.
Groundnuts' profile addresses modern deficiencies, with 75% of diets lacking niacin per 2025 Global Nutrition Report. Integrating them yields measurable health gains.
