The continuing debate over how much protein the average person needs has done little to change our hunger for it. And who can blame us? Protein is one of the basic building blocks of life.
When most people think of protein though, images of cheese, eggs and a leg of lamb pop into their head. Did you know though that every—yes, every—whole food contains protein. From your morning banana to your evening salad, you’re getting protein. Finding plants packed with protein is easy to do and not only is it easy to do, it is easy for your body to use.
Plant-based foods are free from cholesterol, tend to be high in fiber and are often alkalizing to the body. All animal products, on the other hand, are devoid of fiber and are acidifying to the body, which causes calcium to be leached from your bones, as well as decreasing oxygen levels in the blood and negatively impacting the digestive/lymphatic system.
You may have heard the ongoing debate about “complete” or “incomplete” protein and “food combining,” but be wary; these topics are steeped in misinformation and myth. Here’s what I’ve discovered thus far:
The term “complete protein” refers to foods that have all nine essential amino acids present in the correct proportion for our bodies to build protein with. The term “incomplete protein” refers to foods that have all the essential amino acids, but are simply low in one or more of them. This is called the “limiting amino acid.” While it’s true that most whole plant foods have one or more limiting amino acids and are thus “incomplete,” this shouldn’t send you running for a steak.
Our bodies are brilliant and every food that goes into your system must be broken apart and its nutrients absorbed. During the digestion process, amino acid chains from all sources are broken down and made ready for our bodies to use. If you’re eating a good mix of fruits, veggies, grains and legumes, then your body simply collects what it needs from the “amino soup” that your digestion system has absorbed. There are a growing number of vegan bodybuilders, ultra marathon runners and award-winning athletes out there to prove that meeting your protein needs on a plant-based diet is simple and successful.
Since every whole food has protein in it, you have literally millions of great options to choose from when it comes to creating a balanced diet with the right percentage of protein for your body.* I’ve selected ten nutritious plants to get you started, for both their protein content and other health benefits. You may be surprised at some of the veggies, nuts and grains that made it onto my list.
*More is not necessarily better when it comes to protein. Many healthcare professionals are now arguing that recommended daily allowance for protein is too high. No matter whose recommendation you choose to follow, the fact is that each person’s protein needs are different, but all can be met with a plant-based diet.
1. Pumpkin Seeds
9 grams of protein in one ounce
If you’re like me, pumpkin is one of your favorite fall foods. The last time you steamed up some squash or pumpkin, did you have the seeds though? One ounce of pumpkin seeds contains 9.35 grams* of protein. That’s more than two grams more protein then the same quantity of ground beef. Their high protein content and level of nutrients makes them a wonderful addition to any salad or snack.
Pumpkin Seed Nutrients and What They Do:
Tryptophan: Helps fight depression (converted into serotonin and niacin).
Glutamate (needed to create GABA): Anti-stress neorochemical, helps relieve anxiety and other related conditions.
Zinc: Boosts immune function and fights osteoporosis.
Phytosterols: Reduce LDL cholesterol (the bad kind) and up HDL (the good kind); may also be effective in the prevention of cancer.
Pumpkin seeds are also full of manganese, phosphorous, copper, vitamin K, vitamin E, B vitamins such as thiamin, riboflavin, niacin, pantothenic acid, vitamin B-6 (pyridoxine), folates, potassium, calcium, iron, magnesium, zinc and selenium and more.
If pumpkin seeds aren’t your thing, don’t worry—there are plenty of seed-based protein powerhouses out there.
*All protein content by gram is pulled from USDA National Nutrient Database for Standard Reference, Release 18, unless otherwise noted.
3 grams of protein in 8 spears
Grilled asparagus with a balsamic vinegar drizzle is enough to make my mouth water. Eight spears of this delectable veggie has 3.08 grams of protein, which is pretty potent for such a slender fellow.
Asparagus Nutrients and What They Do:
Vitamin K: Asparagus is the number one plant-based source for Vitamin K, which is indicated in preventing osteoporosis and osteoarthritis.
Vitamin A and Folate: Anti-aging, anti-inflammatory, heart healthy and indicated in the prevention of birth defects.
Diuretic: Reduce water retention.
Aphrodisiac: Oh la la!
Asparagus is also a good source of potassium, glutathione, vitamin C, antioxidants (glumatic acid, glycine and cysteine) and more.
2 grams of protein in one cup cooked
For years, I wasn’t a big fan of cauliflower. I mean, how healthy can an off-white vegetable be? But once I started learning about the health benefits of cauliflower and all its cruciferous plant family members, I started to give this veggie its due respect. One cup cooked = 2.28 grams of protein and a truckload of nutrients to reduce your risk for cardiovascular disease and cancer.
Cauliflower Nutrients and What They Do:
Carotenoids (beta-carotene and Phytonutrients): Including kaempferol, ferulic acid, cinnamic acid and caffeic acid. These nutrients help protect your body against free radical damage.
Sulforaphane: Strong indications as a cancer fighting agent.
Omega-3 fatty acids: Reduce inflammation.
Cauliflower is also a good source of vitamin C, manganese, glucosinolates (glucoraphin), vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine) and B9 (folic acid), phosphorus and potassium, indole-3-carbinol (strong cancer fighting indications) and more.
6. 7 grams of protein in one ounce
If you grew up in America you’ve probably had a peanut butter and jelly sandwich or two, but I doubt you knew how healthy this favorite snack really is. One ounce (approximately 28 peanuts dry roasted without salt) = 6.71 grams of protein.
Peanut Nutrients and What They Do:
Co-Enzyme Q10: Protects the heart during times of low oxygen.
Resveratrol: Bioflavonoid believed to improve blood flow in the brain and lower your LDL cholesterol.
Niacin: Assists in recovery of cell damage and protects against Alzheimer’s disease and age-related cognitive problems.

6 grams of protein in one cup, cooked
Oats have gotten a bad rap over the years as a breakfast moosh fit for little orphan Oliver or old school prison inmates, but truly they are a food fit for kings. One cooked cup has a whopping 6.08 grams of protein along with being a great source of fiber and helpful for stabilizing your blood sugar levels. I enjoy mine in the morning with a bit of banana and cinnamon mixed in—yummm.
Oatmeal Nutrients and What They Do:
Selenium (antioxidant combined with vitamin E): Boosts immunity and mood, as well as having indications as a cancer-fighting agent.
Weight loss: Keeps blood sugar levels even. The high level of fiber keeps you full longer.
Magnesium: Helps with energy production, maintaining strong bones and possible relief of PMS.
Phosphorus: Assists with bone health, boosts energy and is important for healthy digestion.
Oatmeal is also a good source of tryptophan, Iron, calcium, B vitamins such as thiamin, riboflavin and niacin; vitamin E, zinc, copper, iron, manganese, magnesium and more.
6. Mung Bean Sprouts
3.2 grams of protein in one cup
You may have seen this little bean hiding in your stir-fry (sprouted) or perhaps in a fresh wrap, but it hasn’t gotten much cred over the years. Most beans are a great source of protein and water soluble fiber and while mung beans aren’t at the top of the bean protein list they make a good showing. With one cup containing 3.16 grams, it is low in calories, but high in content.
Mung Bean Sprout Nutrients and What They Do:
Lecithin: Lowers blood cholesterol levels, reduces liver fat.
Zinc: Along with the protein and other vitamins in mung beans, zinc can help strengthen your nails.
Phytoestrogens: Contain many anti-aging components for the skin. These phytoestrogens act on estrogen-receptors found in the skin, stimulating the synthesis of hyaluronic acid, collagen and elastin, which are all essential components of the skin’s structure.
Mung bean sprouts are also a good source of vitamin A, many B vitamins, vitamin C, vitamin D, vitamin E, vitamin K, folic acid, iron, potassium, calcium, phosphorous, magnesium, zinc and more.
6 grams of protein in one ounce
This is a wonderful snack to have around at all times, both for its protein content and nutrient density. Almonds are at the top of the nut chain when it comes to nutrient density, which means they will keep you full longer. With one ounce (approximately 24 nuts) containing 6.03 grams of protein they are a wonderful addition to any snack or meal.
Almond Nutrients and What They Do:
Phenylalanine: Aids in the development of cognitive function.
Nutrient Rich: Keeps you full longer which can aid in weight loss.
Vitamin E/Magnesium: Important for heart and muscle health.
Almonds are also a good source of calcium, phosphorous, iron, magnesium, zinc, selenium, copper, niacin, managese, riboflavin, folic acid and more.
5.3 grams of protein in one cup cooked
We all know spinach is a special green. From Popeye to the posh salads you’ll find in fine dining restaurants, spinach has gotten some good press and with due reason. One cup cooked = 5.35 grams of protein. It is also filled with flavonoids (a phytonutrient with anti-cancer properties). Spinach is good for your skin, your eyes, your brain and your bones.
Spinach Nutrients and What They Do:
Neoxanthin and violaxanthin: Anti-inflammatory epoxyxanthophylls.
Lutein and zeaxanthin: Protect the eyes against cataracts and age-related macular degeneration.
Vitamin K: Ensures a healthy nervous system and brain function, healthy bones (1000 percent of the RDA of vitamin K in each full cup of spinach).
Vitamin A: Strengthens immunity and promotes healthy skin.
Spinach is also a good source of vitamin C and other antioxidants, flavonoids, beta-carotene, manganese, zinc and selenium and more.
5.7 grams of protein in one cup
Broccoli has many of the same amazing compounds as cauliflower, which is logical due to the fact that they are both in the cruciferous plant family. As a child I remember enjoying broccoli simply for the fact that the pieces looked like tiny trees. Now, as an adult, I enjoy their impressive nutritional profile and the fact that they look like tiny trees. One cup of chopped broccoli = 5.7 grams of protein and a heap of child-like enjoyment.
Broccoli Nutrients and What They Do:
Glucoraphanin (which the body processes into sulforaphane): Helps the skin to detoxify and repair itself, along with ridding the body of H. pylori which increases the risk of gastric cancer.
Beta-carotene, zinc and selenium: All work to strengthen the immune system.
Indole-3-carbinol: A powerful antioxidant and anti-carcinogen, which may hinder the growth of breast, cervical and prostate cancer along with boosting liver function.
Broccoli is also a good source of folic acid, vitamin C, calcium (more calcium in fact then most dairy products), lutein and zeaxanthin, B6, folates and more.
12 grams of protein in 1/2 cup
All of the plants on my list that have preceded this one fall short in comparison to quinoa’s protein potential. On its own it is a perfect protein and the king of all grains. It has the highest percentage of protein content at 16 percent per volume. Meaning that a measly ¼ cup (dry) quinoa has 6 grams of protein. If you paired this grain with a couple of spears of asparagus and a beautiful cauliflower, broccoli and sprouted mung bean stir–fry, you would have an easy meal with 30 grams of protein or more.
Quinoa Nutrients and What They Do:
Magnesium: Relaxes muscles and blood vessels, which can help regulate blood pressure.
Manganese and copper: Both work as antioxidantsto protect the body from free radicals.
Lignans: A phytonutrient found to reduce the risk of heart disease as well as certain types of cancer.
Quinoa is also a good source of iron, calcium, potassium, zinc, vitamin E, selenium, manganese, tryptophan copper, phosphorus and more.

For more than a decade, Susan Jane Brown has been battling to stop a natural gas pipeline and export terminal from being built in the backcountry of Oregon. As an attorney at the nonprofit Western Environmental Law Center, she has repeatedly argued that the project's environmental, social, and health costs are too high.
All that was before this month's deadly wildfires in Oregon shrouded the skies above her home office in Portland. "It puts a fine point on it. These fossil fuel projects are contributing to global climate change," she says.
Moderates Feeling the Heat<p>If elected, Mr. Biden has vowed to stop new drilling for oil and gas on federal land and in federal waters and to rejoin the 2015 Paris climate accord that President Donald Trump gave notice of quitting. He would reinstate Obama-era regulations of greenhouse gas emissions, including methane, the largest component of natural gas.</p><p>The Biden climate platform also states that all federal infrastructure investments and federal permits would need to be assessed for their climate impacts. Analysts say such a test could impede future LNG plants and pipelines, though not those that already have federal approval. </p><p>Climate change activists who pushed for that language say much depends on who would have oversight of federal agencies that regulate the industry. Some are wary of Biden's reliance on advice from Obama-era officials, including former Energy Secretary Ernest Moniz, who is now on the board of Southern Company, a utility, and a former Obama environmental aide, Heather Zichal, who has served on the board of Cheniere Energy, an LNG exporter. </p>
The Push for U.S. Fuel Exports<p>As vice president, Biden was part of an administration that pushed hard for global climate action while also promoting U.S. oil and gas exports to its allies and trading partners. As fracking boomed, Obama ended a 40-year ban on crude oil exports. In Europe, LNG was touted both as an alternative to coal and as strategic competition with Russian pipelines.</p><p>That much, at least, continued with President Trump. Under Energy Secretary Rick Perry, the agency referred to liquified U.S. hydrocarbons as "<a href="https://www.nytimes.com/2019/05/29/us/freedom-gas-energy-department.html" target="_blank">freedom gas</a>."</p><p>Mr. Trump has also championed the interests of coal, oil, and gas while denigrating the findings of government climate scientists. He rejected the Paris accord as unfair to the U.S. and detrimental to its economy, but has offered no alternative path to emissions cuts. </p><p>Still, Trump's foreign policy has not always served the LNG industry: Tariffs on foreign steel drove up pipeline costs, and a trade war with China stayed the hand of Chinese LNG importers wary of reliance on U.S. suppliers. </p><p>Even his regulatory rollbacks could be a double-edged sword. By relaxing curbs last month on methane leaks, the U.S. has ceded ground to European regulators who are drafting emissions standards that LNG producers are watching closely. "That's a precursor of fights that will be fought in all the rest of the developed world," says Mr. Hutchison. </p><p>Indeed, some oil-and-gas exporters had urged the Trump administration not to abandon the tougher rules, since they undercut their claim to offer a cleaner-burning way of producing heat and electricity. "U.S. LNG is not going to be able to compete in a world that's focused on methane emissions and intensity," says Erin Blanton, a senior research scholar at the Center on Global Energy Policy at Columbia University. </p>
Stepping on the Gas<p>In July, the Department of Energy issued an export license to Jordan Cove's developer, Canada's Pembina Pipeline Corp. In a statement, Energy Secretary Dan Brouillette said the project would provide "reliable, affordable, and cleaner-burning natural gas to our allies around the world."</p><p>As a West Coast terminal, Jordan Cove offers a faster route to Asia where its capacity of 7.8 million tons of LNG a year could serve to heat more than 15 million homes. At its peak, its construction would also create 6,000 jobs, the company says, in a stagnant corner of Oregon.</p><p>But the project still lacks multiple local and state permits, and its biggest asset – a Pacific port – has become its biggest handicap, says Ms. Blanton. "They are putting infrastructure in a state where there's no political support for the pipeline or the terminal, unlike in Louisiana or Texas," she says. </p><p>Ms. Brown, the environmental lawyer, says she wants to see Jordan Cove buried, not just mothballed until natural gas prices recover. But she knows that it's only one among many LNG projects and that others will likely get built, even if Biden is elected in November, despite growing evidence of the harm caused by methane emissions. </p>
