Wikipedia - Protein for Women

Foods like yogurt (left) and egg
whites (right) are protein rich foods.
Protein in a women's diet is very important. Protein builds and repair tissues, and it is an important building block of muscles and bones.[1]  A 2005 study published in the American Journal of Clinical Nutrition found that increasing  dietary protein from 15% to 30% results in significant weight loss.[2]

Food with Protein

The best use for protein is to repair and maintain
body tissues. If people eat more protein than they need for tissue maintenance and repair, their bodies use it for energy.[3] Table 1 displays a list of high protein food, servings and the amount of fat.[4]
Protein Intake
The amount of protein intake depends on your weight, age, and activity levels. A survey conducted by Luna found that 50% of women ages 18–50 don't know if they get enough protein. [5]  On average 1 gram of protein is needed for every pound you weigh. For example, if you weigh 130 lbs you would need 47-106 grams of protein a day. [6]  Those who are active and have continuous physical training need to increase their protein needs. [7] The chart below shows an ideal daily protein intake dependent on your genders and lifestyle. [8] 



Breast Cancer
Though there has been controversial research results on the subject of protein's relation to breast cancer, the Shanghai Women’s Health Study found that women with the highest soy protein intakes throughout adolescence and early adulthood had nearly a 60 percent lower risk of pre-menopausal breast cancer than women with the lowest intakes. [9]

Issues
Consuming to much protein can actually be harmful to your body. Dr Gail Butterfield, director of Nutrition Studies at the Palo Alto Veterans' Administration Medical Center indicates that a diet in which protein makes up more than 30% of your caloric intake causes a buildup of toxic ketones. An over-build up of ketones can send your kidneys into overdrive in order to flush these ketones from your body. As your kidneys rid your body of these toxic ketones, you can lose a significant amount of water, which puts you at risk of dehydration, particularly if you exercise heavily. [11]

In addition to heart disease, studies suggest that eating high amounts of protein can contribute to high cholesterol levels, gout and may put a strain on the kidneys, especially those who suffer from kidney disease. [10]

  1. The most-enjoyable part of this post was the table and especially the one that describes the person, situation and goals of the different demographics. Your post was not only focused by also all-encompassing. I thought the inclusion of the issues section was important, helping make it a more balanced and well-rounded piece. Great work!

  2. The volume of facts was impressive and drew you in without boring you. The visuals/charts broke up all the information and made this a good read. I personally liked that you touched on the effects of overconsumption of protein as well.
