Lentils are considered as vitamin-packed, healthy and protein-rich foods. These are categorized as legumes which make them part of the same family as peanuts and beans. It simply means that if an individual has peanut allergy, he/she might also be highly sensitive or allergic to lentils. This is why it is vital that the individual will take proper care by monitoring the symptoms and opting to eat other plant-based proteins instead.
