If I replace meat with corn and beans would I get the protein and amino acids I need?

Question

I want to become vegetarian, and I was wondering if by eating corn and beans I would get the essential amino acids, proteins and supplements that I get from the meat.

Answer 1

Rice and beans toegether have every amino acid, peanut butter sandwich and a glass of milk together have every amino acid.
There is a wide variety!
Cheese, milk, icecream, soy, beans, peanut butter, lentils, peas, nuts, enriched pasta, lots of veggies, soy milk, protein or low carb bars, protein shakes, nut butters, almonds, rice.
Try a wide variety of beans and other legumes. Mushrooms, potatoes, sweet potatoes, pumpkin, wheat products that are enriched, spelt, rice pasta, bulgar, tabouli, garbanzo beans, falalfel, hummus, edame. Quorn products, Veggie burger, veggie patties, etc.

Veg for over 15 years

Answer 2

Personally, I would not worry about it. The has been so much research done to disprove the food combining theory that most heath care professionals pay no attention to it today. As long as you eat a varied diet of, whole plant based foods you really have nothing to worry about. The government set RDA’s for protein are ridiculously high. Humans need a minimum of 5% of calorie intake from protein. The world wide accepted range is between 10%-15%. The only reason that the US has such high RDA’s (up to 35% now!) is because the meat and dairy industry play a huge hand in deciding RDA’s.

In response to the B12 and Iron comments: B12 is not derived from meat. B12 is actually made by an organism in the soil. The reason humans no longer get it from plants even though we use to, is that we simply wash them too carefully. We use to ingest bits of soil when eating plants and received our b12 that way. Now, since the animals still eat “dirty” plants they do absorb it, it’s in their system, You eat and then you got it. This is the ONLY reason Vegans need any kind of supplementation. It’s really a matter of a society that has become too obsessed with cleanliness. As for Iron this one is disproved with a quick glance at the nutrition facts of any green leafy vegetable. Then all contain iron. If that doesn’t make sense think of it this way. Iron is a mineral, not a vitamin, or amino acid. The origin of a mineral, by it’s very definition, can only have one source, the Earth. So the plant absorbs and uses the Iron from the soil, the animal eats the plant and gets the iron from the plant, you eat the animal and get the iron as well. Alternatively, you can skip that whole mess and just eat the plant.

Answer 3

Yes. Any pulse (peas or beans) combined with any cereal (rice, corn, wheat, barley, rye etc) will give you all the essential amino acids you need for your body to make protein. The other thing a vegetarian needs to watch is B vitamin intake. All meats contain it but most vegetable products don't. A useful source is yeast.

Answer 4

Tryptophan ( i guess) is lacking in corn where as methionine is lacking in the beans. If you combine these you will get proteins of complete amino acid profile..............but................. the saddish part of this good news is protenis from vegetable origin are not of as good quality as that of animal origin. There are so many criteria by which quality of the proteins can be judged for eq digestibility coefficient, net protein utilization,biological value and so on. These indicators are to know whether or not proteins injested in the body is utilized by our body in proper way i.e to know can the protein perform their intended job in the body? And all the indicators just CRY to say proteins from animal source ( remember milk and its products are also from animal source) are far better than from plant source. But this does not mean meat is not replaceble; it can be replaced at the cost of protein efficiency; you shold consume more beans and corn to get the same performance as that of meat

Answer 5

The only thing is that you'll be missing iron and B-12, both derived from meat. If you're going to be vegetarian, make sure to take a B-12 supplement and an iron supplement.

Here's a good website about eating complete proteins.

Answer 6

brown rice and beans is a complete protein that will give you all the protein and amino acids that you need.
you might benefit from taking a multivitamin to get the b vitamins and trace elements you need
I don't know about corn and beans

Answer 7

Consult a nutritionist. There are certain combinations of beans and startches that actually cancel out the required amount of protien and amino acids you body will absorb.

Answer 8

I believe that I read somewhere that yes that is the case...that is one of the reasons that early mexican diets were wholesome...of course I could be wrong...but I remember something about the enzymes in beans and corn toether to be mutually beneficial.

Answer 9

you get protein from beans and amino acids from tomato and milk.

Answer 10

One thing to remember is B12, usually a prob if you go vegan, not just vegetarian, but be careful anyway. Tempeh has it.
