8. Peanuts
Both fresh peanuts and peanut butter are rich in niacin. Fresh peanuts may contain up to 10.5 mg of niacin while peanut butter could reach up to 4.4 mg. It is equivalent to 60% and 27.5% of your recommended daily allowance respectively. This is perfect for peanut lovers. Just take it easy though since you might also get loads of calories if you eat a lot. Nevertheless, you only need 100g of serving each day to get close to your daily needs.
9. Coffee
Coffee might have been demonized in many ways, but the truth is that coffee in itself is not harmful. The reason why it becomes unhealthy is because of what we put in it. Some people prefer using whip cream while others place tons of sweetened milk. If you only drink dark coffee, one cup a day will already give you all your daily niacin needs (39.73 mg). Dark coffee is also low in calorie, which is better. Of course, moderation is essential or else you will suffer from all the bad effects of coffee.
