No, red meat is significantly better than spinach for protein content; red meat provides more protein per serving and is a "complete protein," while spinach, though nutritious, requires large quantities to get substantial protein, and animal proteins offer better amino acid profiles and bioavailability. However, spinach offers essential vitamins and minerals, making both valuable for a balanced diet, with the key difference being density and completeness of protein.
Research has shown that all plants contain protein and at least 14% of the total calories of every plant are protein. Broccoli contains more protein per calorie than steak and, per calorie, spinach is about equal to chicken and fish.
Chicken wins the protein crown by about 33x. Spinach is more like the guy at the gym who talks big but suddenly remembers a mystery emergency the second you suggest leg day. BUT - and this is important - this isn't a dig at vegetarians.
LENTILS.
Much like beans, lentils check some important boxes for herbivores. One cup of cooked lentils has nearly 18g of protein — more than the amount in a hamburger — and also contains a lot of fiber, vitamins, and minerals.
A cup of cooked spinach yields 5.3 grams of protein. Other benefits include high levels of iron, folic acid, vitamin C, vitamin K and calcium. Collard greens. A one-cup serving of these dark leafy greens (cooked) contains about 5.1 grams of protein, but if you're like a lot of Tennesseans, you don't stop with one cup.
What's bad about spinach? If you eat spinach every day in excessive amounts (more than a bowl) there can be adverse health effects. Most commonly these include gas, bloating and cramps due to its high fiber content. Eating too much spinach can also interfere with the body's ability to absorb nutrients.

5 of the Best Fruits for Protein Intake
Two eggs a day provide about 12-14 grams of high-quality protein, which is a great start but usually not enough for your entire daily requirement, especially if you're active; most adults need significantly more (around 46g for women, 56g for men), so you'll need to add other protein sources like meat, dairy, beans, or tofu to meet your goals, says the TODAY Show.
Examples of high-protein foods
Proteins that come from animal sources, such as meat, eggs, and milk, as well as soy and quinoa, are called complete proteins. This means they contain all the essential amino acids the body needs and are the highest-quality protein sources.
Spinach. This leafy green packs a protein punch, but only when you eat a large amount of it. One cup of raw spinach has less than 1 g of protein, but the same amount of cooked spinach has 5 g. Spinach cooks down a lot when it's heated, so it takes around 5 cups of raw spinach to make 1 cup of cooked spinach.
Cooked spinach, per cup, provides 129% of the recommended daily vitamin A for women and 105% of the suggested amount for men. Spinach also provides more of the minerals magnesium, potassium and iron than cabbage, lettuce or broccoli.
You should only eat spinach in moderation, about 100-200 grams per week, to avoid an excess of fiber and oxalates. Avoid combining with incompatible foods: Do not eat spinach with eel, soybeans, pumpkin, beans, milk, leeks, cucumbers, sweet potatoes, and purine-rich seafood.
Keep in mind that they're very low in protein and fiber, two nutrients that are crucial for keeping you full. This means that cucumbers are best when combined with other nutrient-dense foods for lasting satiety.
Spinach extract is another widely used food supplement or ergogenic aid, characterized by a high content of phytoecdysteroids, particularly 20-hydroxyecdysone (20E), which have been shown to increase strength and muscle mass during resistance training, to reduce fatigue and to facilitate recovery [20].
Bananas are high in potassium, convenient to eat on the go, and can fuel your body during a workout just as well as a sports drink, according to one study. As if that weren't enough, one medium banana brings 1.3 grams of protein.
To get 100g of protein daily, focus on prioritizing protein at every meal (aiming for 30g+ per meal) by incorporating lean meats, fish, eggs, Greek yogurt, tofu, lentils, and beans, and use protein-rich snacks like nuts, seeds, or protein powder to fill gaps, planning ahead with batch cooking for easy access.
7 Protein-Packed Foods to Add to Your Diet
Following a no-meat diet for 30 days may positively affect your cholesterol levels. High levels of blood cholesterol increase the risk of cardiovascular diseases and increased consumption of meat, which contains a considerable amount of saturated fats, may increase the cholesterol level in your blood.
What 100 grams of protein looks like for vegetarians
In fact, in this study, vegetarians live six to nine years longer, which is a huge effect. But vegetarians are also more likely to exercise, be married, smoke less and drink less alcohol—all factors that also contribute to a longer life.
Here are 12 surprising sources of protein:

Miley Cyrus stopped being strictly vegan because she experienced health issues, feeling malnourished and that her brain wasn't functioning properly after six years on the diet, leading her to reintroduce fish and omegas for better brain function, though she still values animal welfare. She noted feeling "much sharper" and healthier after adding animal products like fish back into her diet, which was a difficult transition emotionally, but a necessary one for her body.
