Jalapeños are rich in vitamins A and C and potassium. They also have carotene -- an antioxidant that may help fight damage to your cells – as well as folate, vitamin K, and B vitamins. Many of their health benefits come from a compound called capsaicin. That's what makes the peppers spicy.

Which peppers contain capsaicin?

Capsaicin is naturally found in all chili peppers, such as jalapenos, habaneros and shishito peppers. If it's a hot pepper or any food made from them (like hot sauce), it's got capsaicin, according to the University of Michigan.

Is jalapenos a fat burner?

Jalapeños may help you lose weight by boosting your metabolism, increasing fat burn and reducing your appetite ( 6 ). Several studies have found that capsaicin and other similar compounds called capsaicinoids can boost metabolism by 4–5% per day, potentially making it easier to lose weight ( 7 , 8 ).
