Jaiapenos are a rich source of vitamin C, with almost 17 milligrams in a small pepper. That is equal to 18 percent of the recommended daily allowance for men and 23 percent for women. Vitamin C is an antioxidant that helps prevent damage from free radicals, rogue molecules that can cause cell damage in your body. Jalapenos also supply a good amount of vitamin A, which supports skin and eye health; one pepper offers 17 percent of the RDA for men and 22 percent for women.
Jalapenos contain Capsaicin. Capsaicin has impressive health benefits, particularly as an anti-inflammatory and vasodilator that promotes healthy blood flow. In addition, a study in the journal “Cell Signal” in 2003 concluded that capsaicin is “promising” for treatment of cancer because it appears to turn off NF-kB, a protein that promotes tumor growth. Capsaicin has also shown promise for weight loss, especially of hard-to-lose belly fat, by increasing energy expenditure after consumption.
