Navigating Vegetarian Protein Sources for Optimal Health


Seeking for trustworthy sources of protein is essential while attempting to maintain a healthy vegetarian diet. Maintaining general health and well-being requires an awareness of the diversity and nutritional worth of various protein sources, regardless of length of time been vegetarian or recent interest in plant-based alternatives.

The amount of protein you need on a daily basis varies depending on factors like your age, sex, weight, height and level of physical activity. Suggested daily amounts also vary depending on whether you’re pregnant or breastfeeding.

For instance, per U.S. Department of Agriculture (USDA) guidelines, it’s suggested that women ages 19 to 30 consume between 5 and 6.5 ounce-equivalents of protein per day—with 1-ounce equivalents measuring out to 1 ounce of meat, one egg or 1 tablespoon of peanut butter. Women ages 31 and up are advised to get 5 to 6 ounce-equivalents. Meanwhile, the USDA recommends 6.5 to 7 ounce-equivalents for men ages 19 to 30, 6 to 7 ounce-equivalents for men ages 31 to 59 and 5.5 to 6.5 ounce-equivalents for men ages 60 and up.

One important caveat to these numbers: The USDA guidelines are for the minimum amount of protein needed to keep someone from becoming deficient. Many individuals may need to consume more than this, especially if they are trying to build muscle.

Plant-Based Diets and Protein:

“If someone is following a vegan or vegetarian eating pattern, they can certainly meet their protein needs with an appropriately planned vegan or vegetarian eating pattern,” says Yasi Ansari, a registered dietitian and national media spokesperson for the Academy of Nutrition and Dietetics.

“If you are a whole-foods plant-based vegan, meaning you’re eating a variety of foods, it’s probably going to be pretty easy to meet your protein needs,” adds Grace Pascale, a San Diego-based registered dietitian nutritionist with a focus on plant-based, vegan and vegetarian nutrition. However, per Pascale, those who are so-called “junk food vegans,” who tend to rely more on highly-processed foods, “often will have fewer sources of those nutrient-rich plant foods” that provide protein.

However, those sticking to an entirely plant-based diet should be aware of the distinctions between complete and incomplete protein as they craft their meals. Whereas animal-derived protein sources are considered complete proteins, as they have all nine essential amino acids, many plant-based proteins are considered incomplete proteins because they don’t have all of the necessary amino acids. That said, it is possible to pair two or more incomplete proteins to create a complete protein. For instance, the pairings of beans and rice as well as nut butter and whole grain toast can result in a complete protein—although eating these foods at different times of the day also works.

Top Protein Sources for Vegans and Vegetarians:

Here’s a look at some of the best protein-rich vegetarian and vegan foods, and the nutritional benefits they can offer.


In Pascale’s opinion, the “foremost” protein source for vegans and vegetarians is tempeh, which she describes as a fermented alternative to tofu that’s made with a whole soybean. “I love tempeh because it’s great for the gut, rich in fiber and it’s really tasty and it marinates well,” says Pascale.

In terms of its protein content, 1 cup (or 166 grams) of tempeh contains an impressive 33.7 grams of protein. Tempeh is also a source of fiber, which, when paired with protein, can help you feel fuller for longer. Additionally, tempeh provides probiotics, which benefit gut health.


According to Ansari, “one of the highest sources of protein is lentils,” which are technically seeds derived from the pod of the legume plant, making them a type of legume. One cup of lentils provides a notable 47.2 grams of protein. Important to note this is one cup dry lentils, one cup on cooked lentils is about 18 grams protein.

Lentils offer a number of other beneficial nutrients as well, per Ansari. “Lentils are high in iron, fiber, potassium and vitamin B6,” she says.“Eating lentils can support digestion and brain health and may offer protection against the development of heart disease while providing energy.”

Indeed, studies show that lentils are associated with reduced incidence of diseases like diabetes, obesity, cancers and cardiovascular disease, most likely due to the polyphenols (plant compounds that act as antioxidants) and other bioactive compounds they contain.


Another type of legume that can provide an excellent source of protein for vegans and vegetarians is beans. There is a wide variety of beans to choose from, such as kidney beans, pinto beans, white beans, black beans, lima beans, fava beans and soybeans.

According to the USDA, one half cup of black beans contains almost 7 grams of protein.

Beans offer other benefits as well. All types of beans are rich sources of fiber, potassium, copper, phosphorus, manganese, iron, magnesium and B vitamins, all of which are vital nutrients for the body.

Organic Rice Protein And Pea Protein Isolate

Transparent Labs Organic Vegan protein powder is formulated with organic pea protein isolate and rice protein to help increase performance and muscle recovery.

Nut Butters:

Nut butters, such as peanut butter and almond butter, are another supplemental source of protein for vegetarians and vegans, according to Pascale. One tablespoon of peanut butter offers roughly 3.84 grams of protein, while a tablespoon of almond butter offers a slightly lesser 3.36 grams.

One 2017 study that reviewed the impacts of nut consumption on human health concluded that it has a myriad of benefits. For one, due to the nutritional composition of nuts, eating them regularly can help to prevent and even treat certain risk factors related to chronic disease. Additionally, eating nuts can be helpful when it comes to controlling appetite.

However, when selecting a nut butter, it’s important to look at the ingredient list. “What you don’t want is for it to say something like peanuts, hydrogenated oil and sugar,” says Pascale, who says she opts for nut butters “where it’s just the roasted or raw nut and a little salt, for flavor.”

Because nuts are primarily fat-based, they tend to have a higher calorie count per serving. Because of this, serving size should be especially considered if someone is looking to lose weight.

Hemp Seeds:

Another vegetarian- and vegan-friendly protein source that Pascale praises is hemp seeds, also often referred to as hemp hearts. “They’re so efficient,” she says. “They pack such a punch in that it takes so few to get such a large amount of protein.”

Specifically, 3 tablespoons of hemp seeds pack 9.48 grams of protein. Hemp seeds offer a number of other nutritional benefits as well, including essential fatty acids, fiber, amino acids and vitamins and minerals. They can be prepared in a variety of ways, too, as you can eat them raw, cooked or roasted.

Overview of Sources of Vegetable Protein:

Making the switch to a vegetarian diet frequently raises concerns about how to acquire enough protein without meat. Luckily, a wide variety of plant-based foods provide enough protein as well as important minerals, fiber, and antioxidants. Let’s examine the several types of plant-based protein sources and their advantages.

For vegetarians, dairy products such as Greek yogurt, cottage cheese, and milk are traditional sources of protein. But for those who If you’re lactose intolerant or on a vegan diet, non-dairy substitutes like cashew cheese, soy yogurt, and almond milk have a similar protein content.

Surprising Protein Power of Vegetables:

Vegetables nonetheless provide significant amounts of protein to the diet, even though they might not be as high in protein as other foods. Vegetables having a higher protein level include peas, Brussels sprouts, spinach, and broccoli. They also contain a variety of vitamins and minerals.

Putting Proteins Together for Whole Nutrition:

It is advantageous to mix different plant-based proteins throughout the day to guarantee a well-rounded amino acid profile. Combining grains with legumes or nuts with seeds produces complementary proteins that enhance nutritional value and promote general well-being.

Satisfying Protein Requirements: Both Amount and Type:

Meeting dietary demands requires an understanding of each person’s specific protein requirements.
