A common misconception about vegetarian diets is that they lack sufficient protein. However, vegetarians can obtain protein from various plant sources, including beans, peas, lentils, nuts, seeds, and soy products. These plant-based sources can provide adequate protein to meet the recommended daily intake, which is approximately 46 grams for women and 56 grams for men, although individual needs may vary. Additionally, vegetarians who consume dairy products and eggs have access to additional protein sources, such as Greek yogurt, milk, and eggs, ensuring they can maintain a healthy and well-rounded diet without missing out on essential nutrients.

Legumes, beans, and pulses
The protein content in pulses varies depending on the specific variety and the conditions in which the crop was grown. For example, green split peas and yellow split peas are considered pulses, whereas fresh peas are not as they are not dried before preparation and consumption. A serving of 80 grams of green split peas contains approximately 6 grams of protein, making them a great addition to soups, stews, and curries.
Kidney beans, white beans, mung beans, and brown beans are all types of pulses that offer a significant amount of protein. Pulses such as lentils, chickpeas, black beans, and peas are also good sources of plant-based protein.
Legumes, such as soybeans, are another great source of protein for vegetarians. Soybeans are considered a whole source of protein, providing the body with all the essential amino acids. Boiled soybeans or edamame provide about 63% of the daily value (DV) for protein, which is currently 50 grams per day. Other legumes that are high in protein include cranberry beans, pinto beans, black beans, navy beans, and limas.
In addition to their high protein content, legumes, beans, and pulses also provide essential vitamins and minerals, fibre, and have a range of health benefits. They are a great way to add plant-based protein to your diet and can be incorporated into a variety of dishes.

Nuts and seeds
Peanuts and pecans, for instance, are rich in B vitamins, while almonds are a great source of calcium and vitamin E. Walnuts are packed with folate, vitamin E, and alpha-linoleic acid (ALA, an omega-3 fatty acid). All nuts contain magnesium.
Just a tablespoon of seeds yields surprising nutrition. Chia seeds, for example, provide 2 grams of protein, 4 grams of fibre, and 78 milligrams of calcium. Flaxseeds, meanwhile, have 2 grams of protein and 3 grams of fibre per tablespoon. Hemp seeds contain 1 gram of fibre and 10 grams of protein per tablespoon.
The Australian Dietary Guidelines recommend a nut intake of 30 grams on most days of the week as part of a healthy diet for adults. According to registered dietitian Kathy McManus, "In just a handful of nuts, which is about an ounce or a quarter of a cup, you get a lot of bang for your buck. They contain anywhere from 3 to 7 grams of protein per ounce, 1 to 3 grams of fibre, and 160 to 200 calories."

Dairy and eggs
Dairy products and eggs are common sources of protein for vegetarians. Eggs, in particular, are a powerful source of protein for vegetarians, as they contain all nine essential amino acids and 6-8 grams of protein per large egg.
There are different types of vegetarian diets, but the most common one, the lacto-ovo-vegetarian diet, includes dairy products and eggs. Other types of vegetarian diets include the lacto-vegetarian diet, which includes dairy but not eggs, and the ovo-vegetarian diet, which includes eggs but not dairy.
Dairy products such as milk are a good source of calcium and vitamin D, although vitamin D is only found in small amounts. Eggs also contain vitamin D, as well as vitamin B12, which is needed for growth, repair, and general health. It is only found naturally in animal products, so vegetarians who eat eggs are more likely to get enough of this vitamin.
In addition to being a good source of protein, eggs and dairy products can also provide other health benefits. For example, a diet that includes eggs and dairy can help to lower the risk of health problems like obesity, heart disease, stroke, and diabetes.

Soy products
Soybeans are considered a whole source of protein, providing the body with all the essential amino acids it needs. Soy and soy foods are common nutritional solutions for vegetarians due to their high protein content and versatility in the production of meat and milk substitutes. Soybeans are used for the production of several analogues and surrogates of meat and dairy products that might be used as alternatives, especially during the transition to a vegetarian diet.
Soybeans are also rich in folate, vitamin K, and fiber. Soy foods have been linked to a protective role in breast cancer, with studies showing that soy intake after diagnosis of breast cancer favourably affected prognosis. Soy milk, edamame, tofu, and soy cheese are some examples of soy foods.
Textured soy protein, also known as textured vegetable protein or TVP, is a soy product that has gained popularity in recent years. TVP is packed with protein, healthy fats, fiber, and vitamins and minerals. It is also easy to cook and versatile, with a neutral taste and smell that can acquire the flavor of whatever it is cooked with. It is often used as a main ingredient in meat alternatives due to its meat-like texture.

Whole grains
Similarly, amaranth is a pseudocereal and a complete source of protein. Once considered a staple food in Incan, Mayan, and Aztec cultures, it has become a popular gluten-free grain alternative. Amaranth has a delicate, nutty taste and retains its crunch even when cooked. One cup (246 grams) of cooked amaranth provides over 9 grams of protein and 5 grams of fibre. It is also rich in manganese, iron, magnesium, and phosphorus.
Oats are another easy and tasty way to add protein to a vegetarian diet. Half a cup (40 grams) of dry oats provides approximately 5 grams of protein and 4 grams of fibre. Oats also contain magnesium, zinc, phosphorus, and folate. Although oats are not considered a complete protein, they do contain higher-quality protein than other commonly consumed grains like rice and wheat.
Other whole grains that can be incorporated into a vegetarian diet include farro, black rice, and wild rice. Ezekiel bread is another option, made from sprouted whole grains and legumes, including barley, soybeans, wheat, lentils, millet, and spelt. This combination of whole grains and legumes makes it a complete protein.
In addition to these specific examples, whole grains in general are a good source of protein for vegetarians. They can be included in various dishes, such as salads, soups, or grain bowls, and provide a good base for a vegetarian meal.
