However, tomato provides only 4 of the 9 essential amino acids sufficiently - it is a little low on isoleucine, leucine, lysine, methionine and valine. Tomato pairs well with carrots, pumpkin seeds, hedge mustard seeds, chia seeds or spirulina to create a complete protein profile.
Tofu, tempeh, and edamame
Soybeans are considered a whole source of protein. This means that they provide your body all the essential amino acids it needs.
The tomato (Lycopersicon esculentum) protein, termed XEG inhibitor protein (XEGIP), inhibits XEG activity by forming a 1 : 1 protein:protein complex with a Ki approximately 0.5 nm.
Which foods are complete proteins? Animal proteins are complete, including meat, poultry, fish, eggs and dairy. There are also a few plant-based sources of complete protein, including: Quinoa.
No. Tomatoes are fruit. There's very little protein in a tomato (or any fruit) and what is there is not a complete protein. A whole, small tomato provides not even a single gram of incomplete protein (0.8).
Some plant foods contain anti-nutritional factors that decrease protein digestibility. Legumes, cereals, potatoes and tomatoes contain inhibitors that reduce protein digestibility by blocking trypsin, pepsin and other gut proteases (Savelkoul et al., 1992; Liener, 1994; Friedman and Brandon, 2001).
Avocados don't contain all the amino acids used by your body to build protein-based structures, but they contain all the essential ones. Essential amino acids must be obtained from the diet, whereas your body can make the non-essential types.
Animal Protein & Plant Protein
Plant proteins are considered incomplete because they do not have all of the essentials. But plant-based foods like legumes (including beans and peanuts), nuts, seeds, grains and vegetables still have varying amounts of protein.
Tomatoes are loaded with a substance called lycopene. It gives them their bright red color and helps protect them from the ultraviolet rays of the sun. In much the same way, it can help protect your cells from damage. Tomatoes also have potassium, vitamins B and E, and other nutrients.
Yes, meat and eggs are complete proteins, and beans and nuts aren't. But humans don't need every essential amino acid in every bite of food at every meal — we only need a sufficient amount of each amino acid each day.
Tomatoes. The fiber in tomatoes promotes the growth of good bacteria and discourages harmful bacteria such as C. difficile from gaining a toehold in the gut, according to Canada's GI Society. Tomatoes are also an outstanding source of lycopene, a powerful antioxidant linked to a reduced risk of stroke.
Incomplete Protein Foods. According to Harvard Health Publishing, all animal-based foods, including meat, dairy, and eggs, contain complete protein. The majority of plant-based protein sources, such as whole grains, legumes, seeds and nuts, spinach, broccoli, and mushrooms, are incomplete.
A Source of Incomplete Protein
Although sweet potatoes add some protein to your diet, plant-based protein foods are incomplete. This means that they do not provide all of the more than 20 essential amino acids your body needs on a daily basis.
Surprisingly, potatoes offer a complete protein if you eat enough, over 10 per day. But you would ultimately encounter deficiencies in vitamins A, B12 and E, and calcium and selenium if you keep to just potatoes.
Quinoa is a super grain for good reason. It is one of the few plant foods that is high in protein and contains all 9 of the essential amino acids while also being high in fibre, magnesium, B vitamins, iron, potassium, calcium, phosphorus, and many vitamins.
Moskovitz suggests combining corn, peas, tomatoes, chickpeas, edamame, kidney beans and onion with some oil and vinegar and serving over 2 cups of spinach for a meal packed with 27 grams of protein. Make a stir-fry with soybean tofu with baby corn, water chestnuts, bok choy, broccoli and teryiaki sauce.
The casein in Greek yogurt is a complete protein because it contains all nine essential amino acids: methionine, lysine, isoleucine, histidine, valine, tryptophan, threonine, phenylalanine and leucine.
Oats contain all nine essential amino acids necessary to make up a complete protein. However, oats don't have quite enough of the amino acid lysine to qualify as a complete protein.
When a protein lacks one or more of the nine essential amino acids, it is known as an incomplete protein. Peanut butter lacks the essential amino acid methionine, but is high in lysine. All plant-based proteins are incomplete protein sources except for soy and quinoa.
Guava. Guava is one of the most protein-rich fruits around. You'll get a whopping 4.2 grams of the stuff in every cup. This tropical fruit is also high in vitamin C and fiber.
