For instance, you can't get all the amino acids you need from peanuts alone, but if you have peanut butter on whole-grain bread you're set. Likewise, red beans won't give you everything you need, but red beans and rice will do the trick. The good news is that you don't have to eat all the essential amino acids in every meal. As long as you have a variety of protein sources throughout the day, your body will grab what it needs from each meal.
How Much Is Enough?
You can figure out how much protein you need if you know how much you weigh. Each day, kids need to eat about 0.5 grams of protein for every pound (0.5 kilograms) they weigh. That's a gram for every 2 pounds (1 kilogram) you weigh. Your protein needs will grow as you get bigger, but then they will level off when you reach adult size. Adults, for instance, need about 60 grams per day.
To figure out your protein needs, multiply your weight in pounds times 0.5 or you can just take your weight and divide by 2. For instance, a 70-pound (or 32-kilogram) kid should have about 35 grams of protein every day. If you only know your weight in kilograms, you need about 1 gram of protein each day for every kilogram you weigh.
You can look at a food label to find out how many protein grams are in a serving. But if you're eating a balanced diet, you don't need to keep track of it. It's pretty easy to get enough protein. Here's an example of how a kid might get about 35 grams of protein in a day:
* 2 tablespoons (15 milliliters) peanut butter (7 grams protein)
* 1 cup (240 milliliters) low-fat milk (8 grams protein)
* 1 ounce (30 grams) or two domino-size pieces of cheddar cheese (7 grams protein)
* 1.5 ounces (90 grams) chicken breast (10.5 grams protein)
* ½ cup (80 grams) broccoli (2 grams protein)
Of course, you can choose your own favorite combination of protein-rich foods — now that you're a pro at protein!
Protein
What do you think about when you hear the word protein? Maybe it's an ad for some protein shake that promises massive muscles? Or is it the last high-protein diet craze you read about? With all this talk about protein, you might think Americans were at risk for not eating enough. In fact, most of us eat more protein than we need. Protein is in many foods that we eat on a regular basis.
This section will help you learn more about protein. You'll find information about what foods have protein and what happens when we eat more protein than we need.
Proteins are part of every cell, tissue, and organ in our bodies. These body proteins are constantly being broken down and replaced. The protein in the foods we eat is digested into amino acids that are later used to replace these proteins in our bodies.
Protein is found in the following foods:
* meats, poultry, and fish
* legumes (dry beans and peas)
* tofu
* eggs
* nuts and seeds
* milk and milk products
* grains, some vegetables, and some fruits (provide only small amounts of protein relative to other sources)
As we mentioned, most adults in the United States get more than enough protein to meet their needs. It's rare for someone who is healthy and eating a varied diet to not get enough protein.
What are the types of protein?
Proteins are made up of amino acids. Think of amino acids as the building blocks. There are 20 different amino acids that join together to make all types of protein. Some of these amino acids can't be made by our bodies, so these are known as essential amino acids. It's essential that our diet provide these.
In the diet, protein sources are labeled according to how many of the essential amino acids they provide:
* A complete protein source is one that provides all of the essential amino acids. You may also hear these sources called high quality proteins. Animal-based foods; for example, meat, poultry, fish, milk, eggs, and cheese are considered complete protein sources.

* An incomplete protein source is one that is low in one or more of the essential amino acids. Complementary proteins are two or more incomplete protein sources that together provide adequate amounts of all the essential amino acids.

For example, rice contains low amounts of certain essential amino acids; however, these same essential amino acids are found in greater amounts in dry beans. Similarly, dry beans contain lower amounts of other essential amino acids that can be found in larger amounts in rice. Together, these two foods can provide adequate amounts of all the essential amino acids the body needs.
Plant versus animal proteins
In terms of healthy eating, you should aim to eat a diet with a higher proportion of plant proteins than animal ones.
Processed foods
Sausages and burgers may be the obvious culprits, but so are smoked foods which are also high in salt.
