Wondering how to do your part on Earth Day? Start with what you're eating.

The EAT-Lancet Commission Report, which was developed by 37 scientists and released last year, found that the best diet for both people and the planet includes a variety of plant-based foods, is low in animal proteins, favors unsaturated over saturated fats and limits refined grains, highly processed foods and added sugars.

Evidence suggests this pattern of eating is linked with a longer life expectancy, and just as importantly, a quality of life that includes a healthier body and mind.

Eating more plant-based foods can do your body (and the planet) a world of good. Past studies show this eating pattern may reduce the risk of heart disease and type 2 diabetes; promote a slimmer waistline and healthier body weight; provide higher levels of important nutrients, such as magnesium, potassium, iron, folate, and fiber; reduce inflammation and oxidative stress that can promote cell damage (which accelerates aging and can lead to chronic diseases) and promotes a sharper mind with fewer memory problems over time.

If the idea of cutting back on meat and dairy sounds difficult, this beginner’s guide to plant protein can help you inch toward a more plant-based diet that’s better for you and the world you live in.

And regardless of whether you want to jump in with both feet or just dip one toe into plant-based eating, you’ll benefit from the protein, fiber and other protective vitamins, minerals, antioxidants and plant compounds these foods offer.

Is it possible to get enough protein if you don’t eat meat?

“It's absolutely possible to meet protein and other nutrient needs without meat,” says Cynthia Sass, RD, a dietitian who specializes in plant-based nutrition. “From a young age we're taught that our bodies need meat. In reality, our bodies need key nutrients that are found in meat, but we can obtain adequate amounts from plant-based foods,” she explains.

What are some easy ways to incorporate plant-based proteins into your menu?

According to Sass, when you're eating healthfully, the bulk of your meals should be plant-based anyway: vegetables, along with a plant-based fat, like extra virgin olive oil, avocado, or tahini and a whole grain or starchy veggie, like quinoa, brown rice, sweet potato or spaghetti squash.

“That means the only switch you need to make is to trade your meat for a plant alternative, which is easier than you think,” she says. “For many people, when they think about what to make for dinner they focus on meat first. Change that pattern by adding pulses (the umbrella term for beans, lentils, peas and chickpeas) and pea protein-based meat substitutes to your protein list,” she suggests.

To get more comfortable with plant proteins, Jackie Newgent, a registered dietitian and author of "The All-Natural Diabetes Cookbook", recommends starting off with plant protein-rich ingredients, like peanut butter or hummus, which you’re already acquainted with and then taking it from there. “For instance, if you’re already enjoying hummus (which is based on chickpeas) as a dip, use it as a sandwich spread or a toast topper,” she says.

Amy Gorin, a plant-forward registered dietitian, suggests a similar approach — in this case, for smoothie lovers: “Blend plant proteins, like edamame, tofu, or canned chickpeas in for a protein punch. These mix-ins pick up the flavors of the other ingredients, and so they won’t taste as strong as if you were to eat them alone.

Another entry-level idea is a protein-based swap. “Consider using hummus in place of cheese in a quesadilla, try tempeh or tofu instead of meat in a stir-fry, and enjoy beans or lentils instead of meat in a chili or taco filling,” says Newgent. Angie Asche, registered dietitian and owner of Eleat Sports Nutrition, LLC, says a plant-based favorite among her athletes is a tofu scramble. “When crumbled up and cooked with nutritional yeast, chili powder, paprika, and a few other spices, it takes on a scrambled egg-like texture that tastes delicious with hash browns, peppers and onions,” says Asche.

5 plant-based proteins to add to your menu

“When using a plant-based protein, take into consideration that its cooking properties can differ from that of an animal-based protein. For instance, if using canned beans in a chili in place of raw ground beef, you won’t need to sauté the beans. Flavor will differ, too. You may get less umami — that savory sense of taste. So, in addition to the plant-based protein, consider punching up taste other ways, like including mushrooms, soy sauce, or other umami-rich ingredients,” says Newgent.

Asche shares similar advice. “Plant-based proteins, such as tofu and tempeh are incredibly easy to make, but they need to be seasoned or marinated. If you try to just cut up some tofu and grill it in a pan, chances are you’re not going to enjoy it,” she says.

Just how much protein you can get from plant-based sources can vary. Below is a look at the protein in common plant-based sources, along with some low-fuss ideas to help you ease your way into eating more protein from plants.

1. Pulses

These foods pack a nutritional punch, with meaningful levels of important minerals, like potassium, magnesium, folate and iron that are often in short supply in our diets. Though you can buy them dried (and speed up cooking in your Instant Pot), canned beans make eating these foods really easy. “One of the beauties of plant proteins, like canned beans, is that you don’t have to do much prep. Making a plant-based lunch or dinner can often be much faster than waiting for takeout to arrive,” says Gorin.

One cup of canned chickpeas has about 11 grams of protein, while a cup of lentils has closer to 18 grams; a cup of black beans clocks in at 14 grams of protein.

There are so many ways to enjoy these foods, but some of the easiest are:

2. Nuts

Nuts range in protein from about 4 grams (walnuts) to about 7 grams (pistachios) per quarter-cup. The amount may not sound like much, but it’s pretty close to a boiled egg, which has about 6 grams. Plus, when you factor in the fact that nuts are often combined with other plant-protein sources, it’s easy to see that they can give you a nice boost.

There are endless ways to enjoy nuts and their butters, but here a few more:

  • Chopped and served over warm fruit
  • Added to stir-fries
  • Pulsed into dips and spreads
  • As the “flour” base for baked goods

3. Seeds

A 3-tablespoon serving of hemp seeds has 10 grams of plant-based protein. The same amount of chia seeds has over 5 grams. A 2-tablespoon serving of tahini — a ground butter made from sesame seeds — supplies 5 grams of this nutrient.

For ingredients like nuts and seeds, Newgent suggests sprinkling them into meals you already enjoy. “That can be as easy as adding chia or hemp seeds to your favorite smoothie,” she says. On top of supplying protein, chia seeds absorb up to 10 times their weight in liquid so when using them in smoothies and puddings, you’ll get a thicker, creamy-like consistency.

Seeds are very versatile. Among the ways you can use them are:

4. Grains

Quinoa is probably the most notable protein-rich grain (which is ironic, since it’s actually a seed), but other whole grains supply protein as well. You’ll find about 6 grams of protein in a cup of cooked millet or bulgur, and about 7 grams in the same amount of wild rice; for reference, quinoa has 8 grams per cup. Again, these numbers might not wow you, but when paired with other sources of plant protein, they can add up to meaningful amounts.

Some protein-rich ways to incorporate whole grains include:

  • As a hot cereal stirred with chopped nuts and fruit
  • In a pilaf or casserole made with pulses and other colorful veggies
  • Tossed with pulses into salads and veggie-grain bowls

5. Soy

Like animal sources of protein, whole soy is a complete source of the nine essential amino acids your body needs. Whole soy foods include tofu, edamame, soy nuts, soy milk and tempeh. A 3-ounce portion of tofu has nearly 9 grams of protein — the same amount as a half cup of shelled edamame.

There used to be concerns about whether soy foods, which contain plant-based estrogens that mimic the hormone’s effect, might raise the risk of hormone-dependent cancers (such as breast and prostate cancer). However, looking at all of the existing evidence, the American Institute of Cancer Research says this is not the case, and that in some populations, whole soy foods may even be protective against cancer. That said, the safety of soy protein isolate — a commonly consumed processed form of soy found in meatless burgers, imitation meats, shakes and bars — is still unknown, which is why the advice is to consume whole forms of soy.

When choosing tofu, Gorin recommends taking note of the form you’re using. “If you’re wanting to blend it into a smoothie or use it as a base for making chocolate mousse, I’d recommend soft tofu. I prefer firm tofu for stir-frying or baking — this type is best for if you want a more meaty texture. Many people aren't fans of tofu simply because they don't realize how versatile the ingredient is.”

Here are some easy ways to enjoy whole these foods:

  • Use shelled edamame instead of peas in casseroles and pasta dishes (including mac and cheese)
  • Try swapping extra-firm tofu for chicken
  • Make tofu crumbles to use in place of ground beef or turkey in taco dishes and grain bowls
