Overview

Crushed red pepper flakes are dried ripe Capsicum annuum chilies, typically cayenne-type, coarsely ground with the seeds included rather than reduced to fine powder, producing the familiar flecked condiment that tops pizza and pasta. Because they are essentially the same dried chili as cayenne, their composition is similar: per 100 g they supply roughly 318 kcal, 12 g protein, 57 g carbohydrate, 17 g fat and 27 g dietary fiber. They are rich in provitamin-A carotenoids, providing about 41,600 IU of vitamin A per 100 g from beta-carotene and capsanthin, plus vitamin E (~30 mg), vitamin C (~76 mg), vitamin K (~80 mcg), potassium (~2014 mg), iron, manganese and B6. The defining bioactive is capsaicin, concentrated in the placental tissue and clinging seeds, which binds TRPV1 to drive heat perception, thermogenesis, vasodilation and appetite suppression, and gives the flakes their characteristic slow-building burn. The coarse, seed-inclusive form means flakes release their heat gradually as they steep in oil or sauce. Used as a finishing pinch, crushed red pepper contributes negligible calories while delivering a concentrated daily dose of capsaicin and fat-soluble carotenoid antioxidants prized for metabolic and cardiovascular support.

Health Benefits (4)

• Drives thermogenesis and supports weight management

  moderate
  Capsaicin activates TRPV1 and sympathetic output, raising energy expenditure and fat oxidation while modestly suppressing appetite
• Supports cardiovascular health

  moderate
  Capsaicin promotes nitric-oxide-mediated vasodilation and may improve endothelial function, while high potassium counters sodium's effect on blood pressure
• Supplies provitamin-A carotenoid and vitamin-E antioxidants

  strong
  Beta-carotene, capsanthin and tocopherols quench reactive oxygen species and limit LDL oxidation, protecting tissues from oxidative damage
• Offers anti-inflammatory and analgesic activity

  strong
  Sustained TRPV1 activation depletes substance P in sensory neurons and downregulates inflammatory signaling

Food Pairings

• ·Steep in warm olive oil because capsaicin and the carotenoids are fat-soluble and the oil draws out and carries the heat and antioxidants
• ·Pair with tomato-based sauces because lycopene and the chili's carotenoids together broaden the antioxidant spectrum
• ·Combine with garlic and leafy greens because the fat and the flakes' fat-soluble nutrients enhance overall absorption

Practical Tips

• ·Add flakes early when cooking in oil so the capsaicin and pigments have time to infuse, or sprinkle at the end for sharper, more localized heat
• ·Start with a small pinch and adjust; seed-inclusive flakes can be hotter than expected
• ·Store airtight away from light to slow carotenoid fading and preserve potency
• ·Buy whole-flake products rather than powder when you want gradual, oil-infused heat

Optimal Timing

Capsaicin's thermogenic effects are useful around meals and the carotenoids have no circadian dependency; flakes suit any meal.

Culinary pinches are calorically negligible and fasting-compatible; capsaicin can aggravate reflux in sensitive individuals.
