What Foods have the Best Source of Protein for Women?

Updated: Feb 25, 2020

Best Source of Protein ?

You hear it all the time... you need to get more protein in your daily intake. ..

In our nutrition discussions, I find most women are not getting enough protein in the daily diet. Which food source is the best? Not all proteins are created equal. Clinical Dieticians divide them into the “complete” proteins like soy and animal sources, which contain all nine essential amino acids (EAA), and the incomplete proteins found in most vegetables and grains, which lack one or more EAAs. This would seem to complicate life for vegans, but it turns out that building complete dietary proteins is easy for those who know how to “complement.”

Proteins are ranked according to amino acid content and digestibility, typically via the Protein Digestibility Corrected Amino Acid Score (PDCAAS). The highest PDCAAS for a food is 1.0, meaning that after digestion, it provides at least 100% of the recommended amount of essential amino acids per unit of protein. Whey, milk, casein, egg whites and soy all score 1. Vegetable proteins can be combined to create a perfect score (Schaafsma 2012). Since I train a great deal of women in pre menopause or are on that journey, I suggest they keep soy protein to a minimum so it will not affect their hormone levels.

For Non Vegans: Meat, Fish, Eggs and Dairy

Packed with all nine EAAs, animal proteins are complete proteins, abundant in essential nutrients like B12, calcium, zinc and iron. Good choices include dairy and lean meats. An ounce of beef or chicken provides 7-10 grams of protein and a cup of milk contains nearly 8 grams. A large egg has 6 grams of protein, with nearly equal amounts in the yolk and white (USDA 2013).

Six ounces of yogurt has 6 grams of protein. Most Greek yogurts contain double the protein of regular versions. Yogurt also is a good source of calcium, B vitamins and live active probiotic cultures (NYA 2013).

Thinking about going Vegan or just don’t like meat? Try Super Seeds

Flax, sesame and sunflower seeds provide 2-5 grams of protein per ounce. Ditto with trendy hemp and chia seeds. Potent pumpkin seeds triumph with about 9 grams per ounce. Seeds are good sources of healthy fats, vitamin E and essential minerals like magnesium, copper and zinc (USDA 2013).

Nuts Almonds, walnuts and cashews provide 6-8 grams of incomplete protein per ounce. Packed with healthy fats, fiber, vitamin E and minerals, nuts are an integral part of the Mediterranean Diet (Guasch-Ferre et al. 2013). Nut-rich diets can lower cholesterol (Damasceno et al. 2011); the FDA allows the claim, “Scientific evidence suggests, but does not prove, that eating 1.5 ounces per day of most nuts (e.g.: almonds, hazelnuts, peanuts, pecans, some pine nuts, pistachio nuts and walnuts) as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease” (FDA 2013).

Legumes Alfalfa, clover, peas, beans, lentils, carob, soy and peanuts are well-known legumes. Of these, soy contains the most protein with about 43 grams per 100-gram (3.5-ounce) serving. Edamame, tofu and soy milk are complete vegan proteins (Hughes et al. 2011). Beans and lentils are good sources of incomplete protein, with the added benefits of high fiber and B vitamins.

I have several ladies who are choosing to be a vegan, but according to their daily food logs they aren't always making complete proteins with their food choices. So, How do you make a COMPLETE protein? By combing two of the following vegetable proteins together – examples below. You can avoid soy and meat altogether with these.

  • Lima beans and corn

  • Rice and beans

  • Hummus on whole-grain bread

  • Whole grain noodles with peanut sauce

  • Beans and tortillas

  • Peanut butter on whole-grain crackers

I like to remind my clients that I can’t help them make changes in their health, energy and body composition until they are diligent about making better food choices .
