Overview

Peanut flour is produced by pressing oil from peanuts and grinding the remaining solids into a fine powder, originating from South American legumes now cultivated globally. As a defatted product, it concentrates protein and micronutrients while reducing caloric density compared to whole peanuts. Rich in plant-based protein with a complete amino acid profile, peanut flour provides approximately 34g of protein per 100g, supporting muscle maintenance and satiety—critical factors in longevity nutrition. The high fiber content (15.8g per 100g) promotes gut microbiome diversity and stable blood glucose, both associated with extended healthspan. Notably dense in polyphenols like resveratrol and procyanidins, peanut flour exhibits antioxidant and anti-inflammatory properties documented in cardiovascular research. Its potassium content (1,358mg per 100g) supports healthy blood pressure regulation, while niacin aids DNA repair mechanisms. The retention of monounsaturated and polyunsaturated fats (17.8g combined) provides cardioprotective lipid profiles. Peanut flour's versatility as a baking ingredient, protein supplement, or thickening agent makes it practical for longevity-focused diets seeking plant-based protein density without excessive calories.

Health Benefits (5)

• Muscle preservation and recovery support

  strong
  High protein content (33.8g per 100g) with complete essential amino acids supports muscle protein synthesis, particularly important for maintaining lean mass during aging and post-exercise recovery.
• Cardiovascular disease risk reduction

  strong
  Polyphenols (resveratrol, procyanidins) and monounsaturated fats improve endothelial function and reduce LDL oxidation, while potassium supports blood pressure regulation.
• Glycemic stability and metabolic health

  moderate
  High fiber (15.8g per 100g) and protein slow glucose absorption, reducing postprandial blood sugar spikes and supporting insulin sensitivity over time.
• Gut microbiome diversity enhancement

  moderate
  Resistant starch and dietary fiber serve as prebiotics, promoting growth of short-chain fatty acid-producing bacteria linked to reduced inflammation and improved metabolic health.
• Antioxidant and anti-inflammatory support

  moderate
  Polyphenol content neutralizes reactive oxygen species and modulates inflammatory pathways, supporting cellular protection and reducing chronic disease risk.

Food Pairings

• ·Pair with vitamin C-rich citrus or berries to enhance iron absorption from the peanut flour's plant-based iron, as ascorbic acid reduces ferric to more bioavailable ferrous form.
• ·Combine with fatty fish or flaxseeds to optimize absorption of fat-soluble compounds and provide complementary omega-3s alongside peanut flour's polyunsaturated fats.
• ·Mix with whole grains (oats, quinoa) to create complete protein profiles with all essential amino acids in optimal ratios for muscle synthesis.
• ·Pair with leafy greens to leverage synergistic antioxidant effects and enhance mineral bioavailability through diverse polyphenol profiles.

Practical Tips

• ·Store peanut flour in an airtight container in the refrigerator or freezer to prevent oxidative rancidity of residual oils; unopened shelf-stable products last 6-12 months.
• ·Use as a 1:1 flour substitute in baking recipes calling for wheat flour, but reduce liquid by 10-15% as peanut flour absorbs more moisture due to high protein content.
• ·Blend 2 tablespoons into Greek yogurt or unsweetened plant-based milk as a quick 10g protein boost without the fat content of whole peanut butter.
• ·Select non-GMO, single-origin peanut flour with minimal processing to preserve bioactive polyphenol content and reduce aflatoxin contamination risk.
• ·Incorporate into energy balls with dates and coconut oil as a portable post-workout snack delivering both protein and carbohydrates for muscle recovery.

Optimal Timing

High protein content (33.8g per 100g) combined with moderate carbohydrates optimizes muscle protein synthesis when consumed within 1-2 hours post-exercise, while fiber slows digestion for sustained amino acid delivery.

Also suitable for midday meals to support satiety and stable energy; timing flexibility allows incorporation into breakfast baking or snacks based on individual preference.
