After eliminating meat as their primary protein source, many vegans and vegetarians may find they “fill the void” by overeating carbohydrates, which can lead to lethargy and malnourishment, says Heather Fleming, founder of consciousnutrition.com, a nutrition consulting service. There’s also a lot of confusion about the best sources of protein. Most new vegetarians and vegans have been taught to combine beans and rice for protein, but that can lead to digestion issues such as bloating, diarrhea and constipation. “Plant-based proteins need an acidic environment to break down, while carbohydrates require an alkaline environment,” Fleming says. “Combining them can cause distress.” Highlight foods and products that can assist new vegetarians and vegans in balancing their proteins, carbohydrates and fats.
