This hearty stuffed squash gets a double dose of protein from fluffy quinoa and chewy meatless crumbles.

“How do you get enough protein?” is a question vegan duathlete Lisa Gawthorne has been answering for 20 years, often after crushing a run-bike-run race—she’s won both the European and World duathlon championships in her age group.

As a member of Team Great Britain and athletics club Vegan Runners, she covers her uniform in patches and pins advocating a plant-based diet. “I’m very vocal about being vegan for the animals,” she says. “It’s at the center of everything I do.”

She’s always happy to chat about the benefits of plant-based eating—from better sleep, skin and digestion to faster muscle recovery. She attributes her body’s resilience to the anti-inflammatory phytonutrients (natural plant compounds) in vegetables, nuts, seeds and legumes.

“I realized I was recovering much faster after races than my teammates who were younger,” Gawthorne explains. Sharon Palmer, plant-based dietitian and author, agrees that getting enough protein seems to be on everyone’s mind. “It’s the most common question I get,” she says. “But research shows that people who eat plant-based are meeting their protein needs.”

So just by eating plant-based, I cover all the bases. I’m getting health benefits, I’m helping the planet—and I’m helping animal welfare.”

Protein is made up of 20 amino acids that your body needs, including nine that your body can’t produce on its own. Soy products, quinoa, hemp and chia seeds, nutritional yeast (a savory powder used to flavor foods), amaranth and buckwheat contain enough of all nine for them to serve as “complete” proteins, while most plant proteins don’t have enough of one or two. But that’s easy to work around.

“There used to be this idea that you had to combine foods, like beans and rice, at the same meal,” to absorb amino acids properly, Palmer explains. “Now we know your body can pool those amino acids over the course of a day.”

Palmer recommends including at least one high-protein ingredient in each meal and reaching for protein-rich snacks. Her go-to protein sources include grains (oats, quinoa, brown rice), legumes (beans, lentils, chickpeas), soy products (tofu, tempeh, edamame), nuts (peanuts, almonds, pistachios) and seeds (pumpkin, hemp, chia).

The bioavailability (how efficiently your body absorbs protein) can be a bit lower in plant-based foods. Thankfully, studies show that all types of protein support muscle growth, and plant proteins come with added benefits—such as fiber, antioxidants and other essential micronutrients we often ignore—that support overall health and muscle repair.

When faced with friendly skeptics, Gawthorne has been known to pull out her food tracking app to prove her protein credentials: She eats at least 100 grams of protein every day, mostly from seitan and a rainbow of plants. “I think people forget that there’s protein in almost everything we eat,” she says. She encourages the veg-curious to start slowly—such as with Meatless Monday or Veganuary—and to focus on finding one plant-based, high-protein food they really like.

“Protein is one of the most significant foods we consume in terms of our impact on the planet,” Palmer adds, referring to the greenhouse gas emissions, pollution, and outsize land and water use associated with meat and dairy production. “So just by eating plant-based, I cover all the bases. I’m getting health benefits, I’m helping the planet—and I’m helping animal welfare.”
