Although experts sometimes disagree, peas are considered appropriate for the paleo diet when consumed in small amounts. Although legumes are not typically considered paleo, peas are generally accepted because of important differences between peas and other legumes.
The paleo diet encourages people to eat whole, unprocessed foods similar to what early humans ate. Legumes are on the list of forbidden foods because they are high in carbohydrates, phytates and lectins. Peas, however, are accepted because they are consumed fresh instead of being dried like other beans. Peas are also more nutritious and have fewer phytates than other legumes, making them a healthier alternative and acceptable in the paleo diet.
