Benefits Of A Plant-Based Diet: Energy From Proteins

A plant-based diet is a great way to improve your health and reduce your environmental impact. It focuses on eating foods primarily from plants, including fruits, vegetables, nuts, seeds, oils, whole grains, legumes, and beans. This doesn't mean you have to cut out meat and dairy entirely, but rather that you're choosing more of your foods from plant sources. Plant-based diets offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and are often higher in fibre and phytonutrients.

Plant-based proteins are a great way to ensure you're getting enough protein in your diet while also reaping the health benefits of a plant-based diet. Good sources of plant-based protein include beans, legumes, grains, lentils, nuts, seeds, and soy. These foods can be easily incorporated into your diet through dishes like soups, curries, tacos, and salads.

Characteristics of a Plant and Protein Diet

The health benefits of a plant and protein diet

A plant and protein diet, also known as a plant-forward or plant-based diet, focuses on foods derived primarily from plants. This includes fruits and vegetables, nuts, seeds, oils, whole grains, legumes, and beans. It does not necessarily mean giving up meat and dairy entirely, but rather choosing more of your foods from plant sources. This type of diet has been associated with numerous health benefits, including:

Reduced Risk of Chronic Diseases

Plant-based diets are rich in antioxidants, vitamins, and minerals, which have been linked to a lower risk of developing chronic diseases. Specifically, research indicates that replacing some animal-based proteins with plant-based sources may help reduce the risk of heart disease, diabetes, and certain types of cancer.

Improved Gut Health

The high fiber content of plant-based diets improves gut health and promotes better absorption of nutrients. Fiber can also help lower cholesterol and stabilize blood sugar levels, contributing to overall improved health.

Weight Management

Plant-based diets can aid in weight management, as they tend to exclude many foods that lead to weight gain. By focusing on whole, unprocessed plant foods, individuals can maintain a healthy weight, which is an important factor in reducing the risk of various diseases, including cancer.

Lower Environmental Impact

In addition to the health benefits, plant-based proteins have a lower environmental impact. The production of animal-based proteins emits more greenhouse gases, contributing to climate change. By choosing plant-based proteins, individuals can not only improve their health but also positively impact the planet.

Nutritional Considerations

When adopting a plant and protein diet, it is important to ensure adequate nutrition. Choose a variety of plant-based foods to obtain all the essential amino acids required by the body. Include plant-based milks fortified with calcium and vitamin D, and sample different types of whole grains, beans, and lentils to get a full range of nutrients. Nutritional yeast is another excellent source of vitamin B12, which is commonly found in meat.

In conclusion, a plant and protein diet offers numerous health benefits, including reduced risk of chronic diseases, improved gut health, and weight management. By choosing a variety of plant-based foods, individuals can meet their nutritional needs while also positively impacting their health and the environment.

The environmental impact of a plant and protein diet

A plant and protein diet has a lower environmental impact than a meat-based diet. This is because meat production is resource-intensive and has a large carbon footprint.

Meat and other animal products require more life cycle inputs per kilogram of product than plant foods. For example, producing plant protein generally requires less land, water, and energy than producing animal protein and results in less greenhouse gas emissions in aggregate.

Following a plant-based diet is often considered the most effective strategy for reducing greenhouse gas emissions and agricultural land use related to food production and consumption. Plant-based diets also require fewer natural resources for production compared to meat-containing diets.

Plant-based diets are also associated with a reduced risk of developing numerous chronic diseases over the lifespan. This is because plant-based diets tend to be lower in saturated fat, sodium, sugar, and cholesterol.

However, it is important to note that not all meat or animal protein has the same environmental toll. For example, switching from consuming ruminant meat (such as beef) to monogastric meat (such as poultry or pork) reduces the carbon footprint of the diet.

Additionally, it is worth mentioning that edible insects are a high-quality protein source that is less resource-intensive than traditional animal-based protein. Insects have been part of traditional diets in some societies, and references to consuming insects in the United States date back to 1885. Insect protein has recently been encouraged for athletes as well.

How to get enough protein on a plant and protein diet

Protein is one of three macronutrients that our bodies use for energy, and it is essential for creating enzymes, building and repairing cells, and making hormones, among other vital functions. The good news is that you can get enough protein in your diet, whether it's entirely plant-based or includes moderate portions of animal products. Here are some tips to ensure you're getting enough:

Understand Your Protein Requirements

The Recommended Dietary Allowance (RDA) for protein varies by age. For adults, the RDA is 0.8 grams per kilogram of body weight, which translates to about 10-15% of daily calories from protein. However, this may be higher for certain groups, such as older adults, athletes, and those recovering from medical treatments.

Include a Variety of Plant-Based Protein Sources

You can get protein from various plant sources, including beans, lentils, nuts, seeds, whole grains, and soy products like tofu and tempeh. By including a variety of these foods in your diet, you'll ensure you get all the essential amino acids your body needs.

Plan Your Meals

One of the challenges of meeting your protein needs on a plant-based diet is ensuring you consume enough calories. Plan your meals to include a variety of protein-rich plant foods, and consider using tools like the U.S. Department of Agriculture's online nutrition calculator to track your intake.

Consider Combining Plant and Animal Sources

If you're open to including animal products in your diet, you can easily meet your protein needs by incorporating moderate portions of poultry, fish, eggs, and dairy. These provide complete proteins and can complement the plant-based sources in your diet.

Focus on Protein Packages

When thinking about protein, consider the whole picture, not just the amount. Choose protein sources that offer additional nutritional benefits, such as beans and lentils, which are rich in heart-healthy fiber, rather than red and processed meats, which are high in saturated fat and sodium.

Consult a Dietitian

If you have specific health considerations or are recovering from an illness, consider working with a registered dietitian to tailor your protein intake to your individual needs. They can help you determine if you require more protein than the RDA and guide you in creating a balanced plant-based diet.

The best plant-based protein sources

A plant-based or plant-forward diet is one that focuses on foods primarily from plants. This includes fruits and vegetables, nuts, seeds, oils, whole grains, legumes, and beans. A plant-based diet does not necessarily mean you are vegetarian or vegan and never eat meat or dairy. It just means that you are choosing more of your foods from plant sources.

Plant-based diets offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and are often higher in fiber and phytonutrients.

Soy Products

Soy is a complete protein, meaning it contains all nine essential amino acids. Soy products such as tofu, tempeh, edamame, and soy milk are great options for adding protein to your diet. Tofu is also low in FODMAPs, making it a great first plant protein for those with digestive issues. Tempeh, a block of fermented whole soybeans, offers more protein than tofu.

Whole Grains

Whole grains are naturally high in protein and also deliver fiber, vitamins, and minerals to your diet. Examples of protein-rich whole grains include quinoa, wild rice, oats, and buckwheat. Quinoa, in particular, is a good source of plant-based protein as it is easy to use and readily available in dried and pre-cooked forms.

Legumes

Legumes, including beans and lentils, are powerhouses when it comes to plant protein. Different lentil varieties can contain up to 18 grams of protein per cooked cup, while beans can range from 10 to 18 grams per cup. Chickpeas, also known as garbanzo beans, are another excellent source of plant-based protein, providing 15 grams of protein and nearly 13 grams of fiber per cup.

Nuts and Seeds

Nuts and seeds are packed with protein, fiber, complex carbohydrates, and healthy fats. Examples of protein-rich nuts include almonds, walnuts, cashews, and peanuts. When it comes to seeds, pumpkin seeds, hemp seeds, chia seeds, and flax seeds are good sources of protein. Hemp hearts, in particular, stand out for their impressive protein and omega-3 fat content.

Nutritional Yeast

Nutritional yeast, affectionately nicknamed "nooch" by the vegan community, is an inactive yeast with a unique cheesy, umami-rich taste. It provides 3 grams of protein per 2 tablespoons and is also a great vegan source of vitamin B12.

Meat Substitutes

Plant-based meat substitutes, such as seitan, can be a good option when transitioning to a more plant-based diet. Seitan is made from vital wheat gluten and has a chewy, hearty texture that mimics meat. However, it is important to note that seitan is not gluten-free.

How to add more plant proteins to your meals

A plant-based diet can provide all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health, and is often higher in fibre and phytonutrients. Here are some tips to add more plant proteins to your meals:

• Start with what's familiar: If you're used to meat taking centre stage in a meal, try increasing the amount of vegetables, nuts, or legumes in the recipe while reducing the meat. For example, you can add lentils to recipes with ground beef, like pasta bolognese, shepherd's pie, or meatballs.
• Look for plant-based protein recipes with familiar sauces: Sauces like buffalo, marinara, barbecue, tikka masala, honey mustard, and sweet-and-sour pair well with plant-based proteins.
• Explore traditional recipes from Greece, India, Italy, Mexico, and Asia: These cuisines include many plant-based proteins.
• Enhance the texture and flavour of plant-based dishes: Add mushrooms, jackfruit, eggplant, carrots, or artichoke hearts for a heartier texture. For a savoury, umami flavour, add dried tomatoes, winter squash, mushrooms, sweet potatoes, olives, corn, or toasted nuts.
• Experiment with different types of plant proteins: Try plant-based meat alternatives like "meat" balls, burgers, "chicken" tenders, or "fish" fillets. You can also incorporate whole-food sources of plant proteins like legumes (e.g. garbanzo, kidney, black, pinto, or cannellini beans) , seitan (wheat gluten-based), tofu, and tempeh (soy-based).
• Combine plant proteins with whole grains: For example, eat beans, peas, lentils, nuts, or seeds with whole grains like red beans and brown rice, nuts and seeds with barley, or peas and veggies with farro.
• Add plant proteins to mixed dishes: Include beans, peas, or lentils in stir-fries, curries, kebabs, casseroles, and egg dishes.
• Use plant-based spreads and dips: Try nut or seed butters (e.g. peanut butter, almond butter, or sunflower seed butter) on whole grain bread, or as dips for vegetables. You can also use tahini (ground sesame seed paste) to make hummus or other dips and dressings.
• Top your dishes with nuts or seeds: Sprinkle them on oatmeal, yogurt, salads, stir-fries, and other baked foods and desserts.
• Choose complete plant proteins: Soy and quinoa are two plant foods that offer complete proteins, meaning they contain all the essential amino acids. You can make edamame, tofu, or tempeh your main source of protein in casseroles, pastas, or stir-fries.
• Vary your plant proteins: By combining different plant-based proteins, you can get a complete protein profile. For example, grains (rice, wheat, and corn) are low in lysine, while legumes (beans, peas, and nuts) are low in methionine. Eating them together (like whole wheat bread with peanut butter) forms a complete protein.

Remember, plant-based proteins offer a wealth of benefits, and are an excellent way to diversify your protein sources and improve your overall diet quality.
