Studies found that people who eat plant protein have improved metabolism, decreased risk of obesity, and greater longevity. They found that each 3 percent increase in calories from plant protein links to a 10 percent lower risk of death.

Reason #2: Mitigates Damage From Unhealthy Habits

Have a slew of bad habits that are hard to quit? Studies show that the positive effects of eating plant protein persist despite having unhealthy habits like smoking or drinking alcohol. Of course, we’re not endorsing drinking too much, but eating more plant protein can help if you do let loose from time to time.

Reason #3: Reduces Harmful Chemicals

Added nitrates and nitrites in processed meats are part of what makes them unhealthy (though nitrates occur naturally in some fruits, vegetables, and grains, but they are not harmful). By choosing organic plant proteins, you avoid these chemicals, researchers explained. Also, a diet heavy in processed meat can cause inflammation, increasing the risk of disease.

Reason #4: Rich in Nutrients and Fiber

Pulses and legumes, such as lentils, chickpeas, dried beans, and soybeans, are rich in fiber, says Maggie Moon, RDN, author of The MIND Diet. A daily fiber goal is 25-30g per day, she says, and eating plenty of fiber from plant-based proteins will “reduce constipation and keep the digestive tract regular, due to its gut-promoting qualities.” Animal protein does not naturally contain fiber, which gives plant protein a leg up.

Plus, pulses and legumes are “also high in iron, zinc, B vitamins like folate, minerals such as magnesium, potassium and phosphorous, and they are naturally cholesterol- and gluten-free,” Moon explains. Plant proteins are a lower-calorie, nutritious option, and they can improve your digestive health by “fueling the good bacteria in your microbiome,” she adds.

Reason #5: Helps Fill You Up

All of that fiber easily fills you up and helps keep blood sugar levels stable, so you’ll be less tempted to snack aimlessly or eat too large a quantity of more calorically dense foods.

Reason #6: More Affordable

With animal proteins at least twice the cost of plant ones, you can’t beat the price, especially if you buy seasonal veggies.

Reason #7: Good for the Planet

Menus of Change, a joint initiative between the Culinary Institute of America and the Harvard School of Public Health, notes that plant-based proteins typically produce fewer greenhouse gas emissions than their animal counterparts. Greenhouse gas emissions per gram of protein for beef and lamb are about 250 times those of legumes, and 20 servings of vegetables have fewer greenhouse gas emissions than one serving of beef.
