Protein Protein was the first substance to be recognized as a vital part of living tissue. The name was derived from a Greek word meaning “of first importance.” Proteins are the building blocks of many structures in our bodies, and half of our dry body weight (water taken out) is made of protein. More protein facts: All organs, muscles, tendons, cartilage, bones and blood vessels depend upon adequate protein supplies in order to maintain their structure and function. Every cell in the body is held together with proteins. Enzymes that perform essential functions of each cell are proteins. The immune system has a high turnover rate of material that is mostly made of protein, and so inadequate protein leaves one more susceptible to disease. In order to make proteins in our body, we need correct ratios of amino acids, which are the molecules which proteins are made from. These separate amino acids have many important functions in the body: o making hormones and neurotransmitters o detoxifying the tissues and blood o supplying energy. Some foods have complete proteins (they include all the necessary amino acids), and some foods have incomplete proteins (which means they don’t have all the amino acids we need and so must be combined with other protein sources). Be sure to combine grains with legumes in order to make a “complete” protein. Each is missing an amino acid that the other supplies. What follows is a list of the foods that have good quantities of protein. Food Types Approximate protein Meat, chicken and fish Eggs 7-10 grams 7 grams in 1 oz. in 1 egg Dairy & Substitutes Milk (cow & goat) Cheese (cheddar, Swiss) Cottage cheese Yogurt Soy milk Soy cheese Rice or almond milk 8 grams 6-7 grams 12 grams 10-17 grams 3-6 grams 5-6 grams 1-2 grams in 1 cup in 1 oz. in ½ cup in 1 cup in 1 cup in 1 oz. in 1 cup Legumes (beans: refried, lentils…) Tofu Firm tofu Miso 7-9 grams 10 grams 20 grams 4 grams in ½ cup in ½ cup in ½ cup in 2 Tbsp. Nuts & seeds Nut butters Seed butters Grains Bread Rice, oats, buckwheat Quinoa Barley Amaranth 4-7 grams 8 grams 5 grams in 1 oz. in 2 Tbsp. in 2 Tbsp. 1-5 grams 3 grams 11 grams 10 grams 14 grams in 1 slice in ½ cup in ½ cup in ½ cup in ½ cup Garden or soy burger Brewers yeast 11 grams 3 grams in 1 burger in 1 Tbsp. Michael Byrne, N.D. Daily Protein Recommendations infants children women (age 11+) men (age 11+) women, pregnant women, lactating 13-14 grams 16-23 grams 44-50 grams 45-63 grams 54-60 grams 56-65 grams Protein need is based on age, height and weight; one easy way to calculate it for yourself is to: Multiply your weight in pounds by .36 to get grams of protein per day. i.e. 100 lb.s X .36 = 36 grams/day 150 lb.s X .36 = 54 grams/day Note that higher activity levels, lactation and pregnancy all increase protein needs.
