If we pay attention to the food we eat every day, we realize that many proteins found in both food of animal origin, as well as in the plant. This last is where most proteins can be found where some foods contain significantly fewer calories than others.
Egg whites are a great source of protein, but too much of this food leads to a significant increase in calories. Each egg contains 3.6 grams of protein, but only 17 calories, so a moderate diet of eggs can meet the RDA or recommended daily intake of protein. To meet its IDR, you should only eat from 0.6 to 1.2 g protein kg per day. Not to lose the track of these numbers simply divide your weight to 2.2 Kg for what should be consumed in the day. Bear in mind that the yolk has more nutrients than the white.
White meat turkey with its 178 calories are slightly less calories than the same amount of white meat chicken, which contains 196. However the chicken is 35, 1 g protein, rather than the turkey, which contains 33.6. Dark poultry contain more calories than white meat.
People who do not eat meat, overriding the proteins in meat and beans, while at the same time avoid gaining weight. Soy contains more protein and are low in calories. Tofu, or bean curd, has about 30 calories. Black beans contain approximately 7.5 grams of protein.
White fish also has a lot of other meat protein and fewer calories. For example, 3 ounces of steak have only 93 calories and 17 grams of protein while the same portion of salmon has a comparable amount of protein but also calories in 127 gr.
