There's a big misconception that it's hard to get enough protein on a vegetarian diet. The good news is, there are some great vegetarian protein sources, and with just a little planning you'll get all the protein you need.
Proteins are made up of different combinations of amino acids. Your body uses these special combinations to . .
You also need protein for optimal hGH (Human Growth Hormone) production and secretion. hGH is made by the pituitary gland at the base of the brain. It's essential for normal growth and development, but when you age your body produces less.
The result? Loss of muscle mass and an increase in body fat. Studies show that getting enough protein optimizes hGH levels.3
According to some scientists, another way to enhance hGH secretion is to consume 15 to 25 grams of protein after a workout.
The time of day that you eat protein can make a difference. A recent study shows that protein in the morning can help you eat less during the rest of the day.²
The USDA recommends you get the following amount of protein each day:
|Adults and children over the age of four||50 grams|
|Children under four||16 grams|
|Pregnant women||60 grams|
|Lactating women||65 grams|
From an 8-ounce cut of lean beef you'll get about 64 grams of protein. Can you get that much from plant sources? You sure can.
"Protein is especially important for the elderly to support a healthy immune system, prevent muscle wasting, and optimize bone mass."

There isn't a separate protein RDA for athletes, but whether or not athletes and active people need more protein is up for debate.
The American College of Sports Medicine (ACSM), the American Dietetic Association (ADA), and Dietitians of Canada have suggested that vegetarian strength athletes need 0.6 to 0.8 grams of protein per pound of body weight, while endurance athletes need 0.6 to 0.7 grams per pound.
How do you know if you're getting enough vegetarian protein? If you're a runner, for example, and you're consuming highprotein foods and not losing weight, then you're getting enough protein.
Eat a highprotein food right after working out to increase muscle mass.
If you're into strength training, and want to build more muscle, you'll need to add more protein to your diet. This is where protein powders can help. Once you achieve your goals, you can cut back on the additional protein.
Because everyone is different, your best bet is to experiment to see how much protein your body needs.
You can easily get the RDA from vegetarian protein. Fruits, vegetables, beans, lentils, nuts, seeds, and dairy, all have protein. As far as quantity and quality go, the best vegetarian protein comes from soy (especially Tempeh), Seitan, eggs and beans.
Tempeh and Seitan are two of the best sources of vegetarian protein. They're super healthy, loaded with protein, and are great meat substitutes in recipes.
Tempeh is made by fermenting cooked soybeans. Just four ounces of cooked tempeh gives you 22.23 grams of protein. That's 41.3% of the Daily Value (DV). Plus, it has more nutritional benefits than tofu.
Tempeh is easy to digest and it doesn't have the high amounts of phytic acid that unfermented soybeans have. Phytic acid interferes with the absorption of zinc and other essential minerals, including calcium, magnesium, and copper.
Tofu. Tofu is another, healthy soy option. If you don't mind the texture and taste, you can get 6.63 grams of protein from 81 grams (1/4 block) of firm tofu.
Seitan is seasoned wheat gluten. Wheat gluten is the protein component of wheat that gives bread the elasticity and structure that allows it to rise. Every four ounce serving of Seitan has 15 grams of protein.
Beans have loads of protein. With just one cup of cooked, black beans you get 15.25 grams.
And who doesn't love spaghetti. If you eat just one cup of whole wheat spaghetti you get 7.46 grams of protein.
In the nut category, almonds have the most protein. One ounce (24 nuts) has 6.02 grams. Dry roasted pistachio nuts come in second with 5.94 ounces of protein from one ounce (47 nuts). And let's not forget the walnut. They're high in Omega-3 ALA, and one ounce (14 halves) provides you with 4.3 grams of protein.
Eggs are one of the best vegetarian protein sources
Cagefree eggs that are also free of antibiotics and hormones are an incredibly healthy food, especially for vegetarians. One large boiled egg has 6.29 grams of protein.
Plus, they're loaded with nutrients, have all the essential amino acids, and egg yolks are one of the few food sources with natural vitamin D.
It's important, and easy, to get enough protein from a vegetarian diet. The trick is to plan ahead, and use a high protein source in at least one meal a day.
