Crispy on the outside, tender and bursting withfresh herbson the inside,falafelhas grown far beyond its roots as a Middle Eastern street food to become a global favorite. Today, roughly one in 20 restaurants worldwide features it on the menu and entire chains have built their identity around it. In cities like Paris and New York, for instance, iconic spots such asL'As du Fallafeland Taïm draw hours-long lines, bolstered bycelebrityfans like Lenny Kravitz and Natalie Portman. Such popularity isn't surprising, as this humble fritter hits every mark. "People love falafel for its rich, savory flavor, crispy outside and tender, herb-packed interior," says Amy Goodson, a Texas-based nutritionist and registered dietitian atThe Sports Nutrition Playbook. "It also has the advantage of being a plant-based protein option that appeals to both vegetarians and meat-eaters alike." Here's what falafel is, why it can be good for you and what to keep in mind when it comes to moderation. 75996577007 Falafel is a traditional Middle Eastern dish made from ground legumes – typicallychickpeasor fava beans that have been soaked overnight – "then blended with parsley, cilantro,onion, garlic and spices like cumin and coriander," explainsJen Messer, a registered dietitian and president of the New Hampshire Academy of Nutrition and Dietetics. Some modern variations incorporate lentils or edamame. Once mixed, the ingredients are combined with baking powder, shaped into balls or patties and traditionally deep-fried in oil. "But they can also be misted with a little olive oil and air-fried or baked if one wants to decrease fat," says Leslie Bonci, a registered sports dietitian and founder ofActive Eating Advice. Falafel is traditionally served in pita or flatbreads, where it's layered with fresh vegetables, pickles and creamy sauces. Modern takes include falafel bowls piled high withgrainsand greens, or patties swapped in for a burger on a bun. Of course, it can also be enjoyed solo, and is frequently dipped into tahini, hummus or other zesty spreads. Did you see?Whole grains could help with your healthy eating goals. Here's how. No matter how you enjoy it, falafel can be a nutrient-dense addition to your diet. This is mainly due to "chickpeas and fava beans both being great sources of plant protein and dietary fiber," says Messer.Proteinhelps with muscle repair and satiety, while fiber supports digestion and keeps you fuller for longer. In fact, falafel's high fiber content can help close the "fiber gap," Bonci notes, sinceresearch showsthat only about 5% of Americans meet recommended daily fiber intake. "If you are looking for a tasty way to get in another serving of fiber every day, consider trying falafel," she suggests. Legumes also have a low glycemic index, "which is helpful forbalancing blood sugar," adds Messer. They've also been shown to support healthy cholesterol levels, which is among the reasons "a diet that regularly includes legumes is associated with a lower risk of cardiovascular disease," she says. Goodson adds that falafel also offers a broader nutrient profile. "Its chickpeas and herbs supply iron, magnesium, folate andpotassium, which support heart health, red blood cell production and overall well-being," she explains. "Some of its fresh seasoning and spices also provide antioxidants and anti-inflammatory compounds." Good to know:Glucose, insulin and why levels are important to manage. Here's why. But it isn't all good news. Like most foods, falafel's health benefits depend on preparation and portion size. Its traditional deep-fried form, for instance, increases its calorie density and fat content. "Saturated fat can be especially high if fried in certain oils," cautions Goodson. Add-ons can also tip the scales. Heavy sauces, fried sides orwhite pita breadcan turn a wholesome dish into a calorie-heavy or less nutritious option. "And falafel eaten at restaurants or store-bought versions tend to be much higher in sodium than homemade versions," adds Messer. So long as such considerations are kept in mind though, falafel can be a healthful option – especially when served as a substitute for less healthy fare. "Falafel can be a nutritious, plant-based protein choice when eaten in moderation and prepared in a health-conscious way," says Goodson. "This means baking or air frying it and pairing it with fresh vegetables andwhole grains." This article originally appeared on USA TODAY:What is falafel? Dietitians clue us in.
