Healthy Foods to Eat for Niacin
They've appeared in numerous box-office hits but, since they aren't playing a main character, they go virtually unnoticed by the media and audience. But that doesn't make them any less vital to the films in which they appear. Well, certain weight-loss nutrients are a bit like Hollywood's' B-list: No one talks about them, but without them the show couldn't go on—so to speak!
Niacin, also known as vitamin B3, falls into this category. This vital water-soluble vitamin needs to be consumed on a daily basis. "Niacin is important for the conversion of carbohydrates, protein and fat into energy," explains Lisa Cimperman, MS, RDN, LD, Spokesperson for the Academy of Nutrition and Dietetics. It also helps the body's digestive system and nerves function properly and is involved with the production of a variety of hormones. And if that wasn't impressive enough, vitamin B3 may also reduce the risk of heart disease, lower harmful cholesterol levels, and increase your hair growth.
Luckily, getting enough of the nutrient—which is about 16 milligrams a day for adults—isn't too difficult, especially with our list of the best sources. Keep reading to get in the know.
(You'll be pleased to find that many of the most potent sources are also foods that can help you lose weight!)

Despite what you may have heard, white potatoes aren't bad for your health or waistline. In fact, quite the opposite is true.

Peanut butter is the best source of niacin outside of the meats section for vegetarians and carnivores alike. A mere two tablespoons provides more than a quarter of the day's recommended intake!

Canned tuna is the best source of niacin you'll find, and it's jam packed with docosahexaenoic acid, a type of omega-3 that stunts the growth of belly fat cell. Worried about the mercury? Don't be. Canned chunk tuna is considered a "low mercury fish" and can be enjoyed two to three times a week, according to the FDA's most recent guidelines. To keep calories low, don't mix the fish with mayo. Instead, combine your can of tuna with a tablespoon of Dijon mustard, 1/4 cup Greek yogurt and a bit of salt and pepper.
