10 Environmentally-Friendly Proteins…that Actually Taste Good
10 Environmentally-Friendly Proteins…that Actually Taste Good
Food is a part of our daily lives. And in many cases, the way we produce food is a part of the environment’s decline. One of the most significant impacts of food products are greenhouse gas emissions, and the use of energy. And though there are more eco-friendly foods, there is no perfect food, and more often than not, food impacts the environment in some way.

But small changes in the way you eat can have a large impact on your carbon footprint and we are faced with that decision at every meal.
One way to be green is by finding different ways to meet your daily protein needs, which you can find in this list, and because saving the world can be delicious, each food comes with recipes you should try today.
#1 LEGUMES (Pulses)
Legumes consist of plants that produce pods with seeds, such as beans, peas, and lentils. The term “legume” is used to describe the seeds of these plants. Some of the most common legumes include lentils, peas, chickpeas, beans, soybeans, and peanuts. (1)
Regardless of your legume of choice, they are all known to protein-packed, and rich in fiber. Specifically, legumes like lentils deliver twice the amount of protein per serving than quinoa. (2) Pulses also have three times more fiber than brown rice, and one half-cup serving of black beans contains more iron than 3-ounce flank steak. (3) (4) (5) Additionally, they are a source of potassium, abundant in antioxidants, and naturally Sodium- and Gluten-Free.
Legumes are also the most affordable proteins around the world. According to data from The Bureau of Labor Statistics, the average cost for a serving of lentils is $0.10, as compared to $1.49 for a serving of beef, $0.73 for a serving of pork, or $0.63 for a serving of chicken. (6)
Pulses are hailed as one of the most sustainable proteins in the world because they need only one-tenth the amount of water to grow compared to other proteins and are also drought and frost resistant. Legume crops also get nitrogen from the atmosphere, meaning they don’t need chemical fertilizers to grow. Legumes can boost soil fertility by putting nitrogen back into the soil. (7) (8)
Hence, pulses have a lower carbon footprint than almost any other food group and can enrich the soil and reduce the need for chemical fertilizers.
With that said, legumes are a bit controversial because they are gas-producing foods, which can cause digestive trouble because they contain the same anti-nutrients present in grains: phytates and lectins. Click here to learn more.
Though a bit controversial, legumes are a great source of proteins and fiber that is also great for the environment. But when possible, buy organic since most U.S. growers of these crops use chemical pesticides, herbicides, and fungicides to help boost yields and combat weeds and pests. (8)
Eggs are another environmentally friendly protein. Additionally, they are rich in iron, Vitamin A, D, E, B12, Folate, Selenium, Lutein and zeaxanthin, Choline, meaning that through eggs you have the nutrients you need to strengthen your bones, and eyes, through nutrients that strengthen cell regeneration, prevent the breakdown of tissue, and are also rich in antioxidants. (9)
The ecological impact of chickens depends on the treatment of the animal. In other words, chickens that are raised outdoors on a natural pasture diet are one of the best animal-based eco-choices. Because they are free to pasture, they consume what is available on the land, thus they consume feed that is less fossil fuel-intensive, and their waste fertilizes farmland.
Conversely, chickens, which are kept in overcrowded small spaces, are given antibiotics to prevent the outbreak of disease amongst the barn. The FDA linked this practice with increased antibiotic resistance on farms and possibly among humans. Additionally, chickens housed in this manner rely on a diet of mostly corn and soybeans that have a heavy fossil fuel reliance. (8)
Choosing to buy organic eggs helps keep harmful chemicals and antibiotics out of your body and the environment. Organically raised birds are not exposed to pesticides or antibiotics, and there’s no arsenic in their feed. But, choosing organic is not a guarantee that the eggs and the chickens that produced them were not brought up in a concentrated animal feeding operation (CAFO), meaning that there is no way to know if the animals are being kept in a small area. Thus, though it is best to look for pastured chicken and eggs, their treatment is not regulated. (8)

Chicken is a source of lean, low-fat protein that supports muscle growth and development. Eating chicken is also good for heart health, is rich in the essential minerals phosphorus and selenium, Vitamin A, B2, B6, another Vitamin B Niacin, helps boost metabolism, and prevents bone loss. (10)
The chicken industry has made strides towards being environmentally responsible through sustainable chicken production practices to ensure a healthier planet.
Through continuous innovation and by a focus on the best possible bird health, the chicken industry has reduced its use of water, farmland, electricity, greenhouse gasses, and other valuable resources. These continued innovations have demonstrated that the same amount of chicken production today has 50% less impact on the environment than in 1965.

It is better to fill up on eggs and chicken in moderation because while one broiler yields a chicken breast and two thighs, the average hen produces 500 eggs during her lifetime. (8)
Fun Fact–Chicken is a natural antidepressant, eating some poultry will increase the serotonin amino acid levels in your brain, enhancing your mood, blasting stress, and lulling you to sleep. (10)
#4 SOY PRODUCTS
Soy products are some of the richest sources of protein in a plant-based diet. Edamame beans (immature soybeans) contain 8.5 g of protein per ½ cup and tempeh contains about 15 g of protein per ½ cup (11)
Firm tofu (soybean curds) contains about 10 g of protein per ½ cup. Tofu, sometimes called bean curd or soybean curd is a creamy, high-protein, low-fat soy product typically sold in blocks. The Asian staple is also high in calcium and iron. It’s made from soybeans, water, and a coagulant or curdling agent, and absorbs flavors through spices, sauces, and marinades. (12) Additionally, tofu takes on the flavor of the dish; it is prepared making it a versatile addition to any meal. It is also often used as a meat and milk substitute. (13)
When consumed directly, not as animal feed, soybeans, and soy-based foods have a relatively modest ecological footprint. Soybean crops contribute to the Gulf of Mexico’s dead zone, a vast area choked with nitrogen fertilizer runoff dumped by the Mississippi River.
Eating soy is better than eating meat, but it still has a modest environmental impact that one should be aware of. (14)
Additionally, choose organic soy over conventional because it will not be genetically modified (GMO) and grown without chemical pesticides and fertilizers.

Fish is a low-fat, high-quality protein with an abundance of omega-3 fatty acids and vitamins such as D and B2 (riboflavin). Additionally, fish is rich in calcium and phosphorus and a great source of minerals, such as iron, zinc, iodine, magnesium, and potassium. (15)
As the demand for fish continues to rise and unsustainable practices continue to expand many wild fisheries, about half of ocean fish stocks are being harvested at full capacity. Additionally, trade and consumption reached a record in 2018. (16)
Farm-raised fish remain plentiful but often grow in crowded conditions, which means they are doused with antibiotics and pesticides.
Species, like salmon, raised in open-water ocean pens pollute surrounding waters and shrimp production in Asia, which is also the source of almost all the shrimp Americans consume, is a cause behind the destruction of many coastal mangrove forests. (8)
Some fishing methods have a negative eco-impact of some fishing methods, but even then, fish rank as a more environmentally friendly choice than land-based animals.
One thing to do to ensure that your fish is environmentally friendly, use the Monterey Bay Aquarium’s Seafood Watch to learn which fish are best to eat.
Also, be on the lookout for the blue Certified Sustainable Seafood label from the Marine Stewardship Council. When choosing farmed fish, swap salmon for noncarnivorous fish that can be raised in non-polluting enclosed ponds, such as tilapia and catfish.

#6 EZEKIEL BREAD
Ezekiel bread is a nutrient-dense alternative to traditional bread. It is made from barley, wheat, lentils, millet, and spelt providing good amounts of essential nutrients and vitamins. Each slice offers 4 g of protein per slice on its own, and spreading peanut or almond butter adds to its natural protein power. Ezekiel Bread also is a great bread alternative for vegans and vegetarians, with no eggs, dairy, gelatin, or other animal products added.(17)
And instead of adding sugar or syrups, it uses malted barley as a natural sweetener. Paired with its high amounts of fiber and nutrients, sprouted grain bread has a lesser impact on blood sugar levels than wheat bread. Because of the sprouting process, it is also a great option for anyone who wants to lower their gluten intake. Sprouting also creates more fiber content, protein, essential amino acids, and B vitamins, meaning that because of the amino acids, the bread’s proteins are actually complete proteins, which are usually only found in animal products like eggs or milk. (18)
The environmental cost of producing a loaf of bread is a bit of a costly one and for a large amount associated with greenhouse gas emissions comes from just one of the many steps that go into making that loaf, specifically farming.
The study was done by a team of researchers at the University of Sheffield, in the U.K who focused on a specific farm, which was in Lincoln, in the U.K., on a specific mill and a specific [commercial] bakery.”
From the data they collected and analyzed data they found that many stages of production were energy intensive, and involved emissions which includes: growing the wheat, fertilizing it, harvesting the crop, transporting the grains to the mill, grinding the grains into flour, transporting the flour to a bakery and then baking and packaging a loaf of bread.
They found that the vast majority of emissions, nearly 66 percent, came from growing wheat. Intriguingly 40 percent of the 66 is attributable just to the use of ammonium nitrate fertilizers alone, and fertilizers also cause a lot of water pollution when they run off into streams and rivers.
In other words, in order to have eco-friendly bread consumers can create a market demand for loaves that use less fertilizer or use organic fertilizer.

In addition to taking a stance and encouraging the production of loaves made with less fertilizer, another way to make a positive impact would be to make your own bread. By making your own bread you are not contributing to the emissions needed in the transportation of flour, baking and packaging that are produced in bakeries.

#7 NUTS & SEEDS
Nuts and seeds eaten together, are a healthy alternative to livestock, making it environmentally friendly. Nuts are good sources of fat, fiber, and protein, and most of the fat in nuts are monounsaturated fat, as well as omega-6 and omega-3 polyunsaturated fat. (19)
The current Daily Value (%DV) for protein is 50 grams per day. One ounce (1oz) of nuts or seeds is typically equivalent to a handful, or 2-3 tablespoons. Most nuts provide between 8-18% DV of protein per 1oz handful.
High protein nuts and seeds include hemp seeds, pumpkin seeds, peanuts, almonds, pistachios, sunflower seeds, flax seeds, sesame seeds, chia seeds, cashews, and more. (20)
Click here for a list of high protein nuts and seeds.
Choosing between nuts and seeds is a choice about water. Tree nuts like almonds, pistachios, walnuts, and cashews are actually some of the most water-intensive crops grown today.
Seeds, on the other hand, have a much lower water footprint and impact on our environment. Pumpkins, squash, and watermelons require roughly 20 to 90 times less water to grow than tree nuts (excluding rainwater) and the water used to grow squash and melons produces both edible flesh and edible seeds.
With regards to nuts, peanuts greenest because they grow below the ground, making them far more water efficient than other nuts. (21)
Both nuts and seeds are better alternatives when it comes to the environment than meat and other animal products. However, choosing seeds over nuts (except for peanuts) is a far more eco-conscious decision. (21)
A large baked potato offers 8 g of protein per serving. Potatoes are also high in other nutrients, such as potassium and vitamin C. (11) Additionally, they contain iron, phosphorus, calcium, magnesium, and zinc, which help the body to build and maintain bone structure and strength. (22)
Researchers have shown that potatoes are good for the environment and more sustainable than pasta and rice.
In comparison, paste and rice potatoes were shown to have the lowest levels of greenhouse gas. They were also shown to have significantly lower levels of overall water usage than rice.
But while potatoes were found to have the least negative impact on the environment when compared to pasta and rice, growers can still work to improve the environmental sustainability of their growing operations through good fertilizer management and efficient use of machinery.
Work is being done by Potatoes Australia, an industry-funded magazine, to promote industry research and development while keeping growers and stakeholders in the loop with the latest news. (23)
Vegetables are still a better alternative to livestock when it comes to carbon emissions. Still the issue with potatoes is that over the years, the increased concern over the environmental impact is the use of agricultural fertilizers, particularly as non-point sources of water pollution.
Fortunately, potato researchers throughout North America are conducting studies that focus on maintaining or enhancing crop production while reducing the potential of negative environmental impacts such as strategies used in: precision agriculture, cover crops, slow-release fertilizers, and genetic manipulation are key strategies being studied. (24)
Another way that potatoes have an environmental impact is that they need to be cooked to be used, which adds to the energy used in their consumption.
Thus, a consumer should eat potatoes with moderation and cook in eco-friendlier ways, this guide may help.
Fun Fact– French Queen Marie Antoinette gave birth to potato fashion inspired by the bouquet of potatoes she received. The flower instantly became trendy once she made a public appearance with it as decorations to her clothing.
#9 OTHER PROTEIN-RICH VEGETABLES
Dark-colored, leafy greens and vegetables contain protein, but alone, these foods are not enough to meet daily protein requirements. But when combined with other protein-rich foods, vegetables can be a meal full of nutrients.
For example, a single, medium stalk of broccoli contains about 4 g of protein, kale offers 2 g of protein per cup, and 5 medium mushrooms offer 3 g of protein which can be easily paired with proteins (like those mentioned in this blog 🙂 in a salad. (11)

Vegetables have a small environmental impact, as they contribute to only 2.6% of the greenhouses gases produced. (25) In one study, researchers found that red meat was 35 times more damaging to the environment than a bowl of vegetables. (25)
A vegetarian diet greatly reduces an individual’s carbon footprint, but you don’t need to be vegetarian to significantly reduce your carbon footprint. Simply, switching to less carbon-intensive meats can have a major impact as well; for example, replacing all beef consumption with chicken for one year leads to an annual carbon footprint reduction of 882 pounds CO2e. (26)
And vegetables, when paired with appropriate other foods can be a great source of protein and nutrients.
Fun Fact– Kale is so easy to grow that a group of students at the Indiana Academy of Science, Mathematics, and Humanities decided to grow kale for National Kale Day and planted some seeds. Now they have a kale patch in their courtyard.
#10 OAT MILK
Oat milk is a plant-based dairy milk alternative. Because it is strained oat, it is missing a lot of nutrients; thus it is fortified with vitamin D and A, and B12 and one glass also has 3 grams of protein. Even so, oat milk is eco-friendly and can be easily included in a protein-rich meal. (27)
A 200ml glass of oat milk is responsible for around 0.18kg of CO2e, which is slightly more than almond milk, but less than soy or cow’s milk. A liter of oat milk needs about 48 liters of water produced thus, in terms of water, then, oat milk is much lower impact than other kinds of milk and oats use 80% less land to grow than dairy milk requires. (28)
Oat milk, compared to others, has the least impact on the environment, but other non-dairy alternatives such as almond, soy, rice, coconut, and hemp milks are also great.
