Shishito peppers are trendy — how healthy are they?

They’re subtle, they’re spicy, and they’re gaining traction in Pinterest recipes: they’re shishito peppers! With a unique flavor and crunchy texture, these veggies add a touch of heat to a wide variety of dishes, but a simple roast, salt, and serve is also a great, simple preparation method.

If you’re a culinary newbie and don’t know one type of pepper from the next, no worries! In this article, we’ll break down everything you need to know about shishito peppers, including how to identify one, what spice level is right for you, and the best tips for including them in your diet. We’ll also go over the health benefits of shishito peppers and what makes them so coveted.

What are shishito peppers?

Shishito peppers are small green peppers with a slim cylinder shape and a slight curve. These textured vegetables have extremely thin skin and a large cavity in the center, averaging 3-5 centimeters long.

Shishito peppers originated in Japan and are close cousins to the Spanish padrón pepper. In fact, the two are so similar that they’re often confused for one another. Even though they’re both from the same pepper family (capsicum annum) their differences are significant. Padrón peppers have a much smoother texture and thinner skin than the wrinkled shishito. Further, shishitos have a sweeter, milder flavor profile, so they accommodate a wider variety of palates.

Are shishito peppers spicy?

While most shishito peppers have only a mild heat that’s only a bit spicier than your average bell pepper, about one in every 10 packs a punch. Still, even the spicier shishitos may not phase you. At their hottest, these peppers are still milder than your average jalapeño. Shishito peppers clock in at between 100 and 1,000 on the Scoville Heat Scale, depending on their capsaicin concentration, but that looks measly compared to the jalapeño’s 2,500 to 8,000. Even the closely related padrón pepper has a stronger kick at 500 to 2,000 on average.

The game of chance that comes with snacking on shishito peppers is a lot of the appeal, for some. Many like experiencing a bit of spice that isn’t overwhelming, which makes them popular finger foods.

Are shishito peppers healthy?

Whether you want to classify peppers as fruits or vegetables (yup, they’re both) there’s plenty of benefits to adding shishito peppers to your diet. Like many vegetables, these morsels are chock full of fiber, which promotes gut health, lowers cholesterol levels, and keeps you feeling fuller longer.

Shishito peppers are also high in both antioxidants and vitamin C, both of which are key to promoting immune health. Antioxidants rid the body of toxins while Vitamin C promotes the production of even more antioxidants.

For seven Trader Joe’s brand raw shishito peppers, you’ll consume 15 calories, 4 grams of carbohydrates, 1 gram of protein, 2 grams of sugar, and no fat! As an added bonus, capsaicin boosts metabolism so, while you’re consuming scant calories you’re burning more.

Healthy shishito pepper recipe

Blistered shishito peppers are by far the most common (and simple!) way to prepare these spicy veggies. The recipe is so loved, even healthcare superstar Kaiser Permanente made their own version. Simply cook the peppers in olive oil on the stovetop until blistered, then sprinkle with salt and lemon juice. Voila!

Now that you’re in the know about the shishito pepper, get ready to add it to your next meal or charcuterie board. You’ll have better luck finding them during summer when they’re in season, but most large grocery stores will import them year-round. Since you don’t need much to prepare a healthy snack with these peppers, there’s plenty of room for you to get creative, too! From citrus to salt and even smoke, there’s plenty of flavors that will complement and enhance the subtle heat of the tiny green shishito pepper. Happy cooking!

Sweats and joggers now have a place in everyday fashion. With the right outfit and accessories, you can dress up your sweatpants to go almost anywhere from the grocery store to the office. So how can you transform your sweats from PJs to stylish wardrobe staples? Keep reading to discover nine tips for how to look good in sweatpants.

Choose fitted sweatpants, not baggy ones
If you want to dress up your sweats, the first step is to choose the right pair to wear out.

Choose a pair of joggers that are tapered around the ankle or sweatpants that are fitted around the waist and thighs.
Dress up your joggers with heels or boots
Sneakers and joggers are a match made in heaven. But, if you’re trying to make your sweatpants look dressier, wear them with heels or ankle boots instead. These shoes will instantly elevate your outfit and make you look fashionable no matter the occasion.
Treat them like jeans
Think of your sweatpants like your favorite pair of casual jeans; you can pair them with almost any top. Wear them with a cute sweater, button-down shirt, or simple tank top. This styling method works best with black, beige, or other neutral-colored sweatpants so you can let your top draw most of the attention.
