Guess how much protein is a juicy cheeseburger washed 8-ounce smoothie? This is only a meal consisting of two or three times as much as most people need a day.
It is not surprising that Americans chow down on a large number of proteins. We love beef and consume about 67 pounds per capita per year (four times the international average). The popularity of low-carb diets such as Atkins also made of meat, vegetables for food in the diet.
In fact, the average person eats about twice as much protein as their bodies need, according to results from the 2007-2008 National Health and Nutrition Examination Survey conducted by the Centers for Disease Control and Prevention.
How to meet your daily protein needs
The human body uses protein to repair damaged cells and build new ones. Marion Nestle, professor of nutrition at New York University and author of what to eat, says the average adult man needs about 65 grams of protein a day, and the needs of adult women average about 55 grams. Some sources, such as the Centers for Disease Control and WHO says you can maintain a healthy diet with less.
What that really means in terms of food choices? National Institutes of Health, says that most people can meet their daily protein needs by eating two to three servings of small protein-rich foods per day.
Examples of one serving of protein include:
1 egg
2 tablespoons peanut butter
2-3 ounces of red meat, chicken or fish (about the size of a deck of cards)
½ cup of cooked beans as dry beans or chickpeas blacks
Whole grains, seeds, and some vegetables also contain protein, so eating is not difficult enough, even if they do not eat meat. Vegetarians and vegans can easily get what they need to balance the protein inclusions, such as corn or rice and beans and tofu. Nutritionists used to recommend the combination of foods at one meal, but research now shows that it is not necessary.
Are there disadvantages to eat more protein?
Eating large amounts of red and processed meat is associated with higher rates of heart disease and cancer, and most nutritionists like Marion Nestle recommend reducing consumption of meat, especially fatty cuts.
But it is less well known that your choice of proteins can have a significant impact on the environment. Production of meat and milk require vast amounts of fuel, pesticides and fertilizers, and generates greenhouse gas emissions. The Environmental Working Group (EWG) recently published the Guide Meat Eater pointed out that if you ate a small hamburger once a week, it would be environmentally friendly match to take the car on the road for 320 miles.
The meat is also expensive. All proteins are created equal - or register with a doctor's office or money. A typical comparison of three proteins:
Porterhouse
Serving Size: 4 oz

EWG said carbon footprint: second-worst of 20 analyzed
Cost: $ 4
Fat: 22 grams
Saturated fat: 9 grams
Farmed salmon
Serving Size: 4 oz
Protein: 22 g
EWG carbon footprint rating: 5 Pires
Cost: $ 3
Fat: 10 grams
Saturated fat: 2 grams
Lenses
Serving Size: 1 cup
Protein: 17.9 grams
EWG noted carbon footprint: the best
Cost: 20 cents
Fat: none
Saturated fat: zero
Many people consider the meat a delicious and satisfying part of their diet that does not want to sacrifice. But if you want to save money, eat a good nutritious diet, and is concerned about the effects of production of meat and milk is on this planet, you should calculate their own consumption.
Here are some tips to guide consumers of meat AWG:
Reducing portion sizes, eating a hamburger or a steak less than a week, or participate in Meatless Monday to skip the meat (and cheese if you swing), only one day a week.
Choose healthy sources of protein when you can. Beans, low fat yogurt and nuts are rich in protein and low impact.
When you eat meat and cheese, eat the highest quality you can afford. (One way to save money is to eat less but better quality meat and dairy products.) Here's a guide to decipher the labels on the box without grass-fed.
Do not miss the meat. Accounts of the meat consumed 20 percent of emissions of greenhouse gases in the flesh.
You do not need to become vegetarian, or go the other extreme. These small changes will help to reduce the effect, while the high-protein diet.
