we don't count the protein from yogurt? not even the high protein yogurt? 12 Grams?
I do.
I
count protein from everything in my totals for the day (beans, grains, vegetables, yoghurt etc). Whether the amino acids you digest are from a source that is complete or incomplete, the body will use them, so it doesn't matter if it is from a kidney bean or a king-fish.
BUT, due to the differences in the digestability, bioavailability and efficiency of the different proteins you will get different uptakes from your intestines AND you will get differences in the ability of your body to use those amino acids for productive growth. So this means you should aim to get an
absolute minimum of 1.0g/pound of the highly digestable proteins (such as those in meats, eggs, lean dairy, protein powders etc) and then count the extra stuff as a bonus.
Sure, problems occur when you start relying on incomplete proteins for your major proteins sources - however, for most people these only really occurs if the diet is severely limited in your sources of protein (eg: You live off rice and rice alone) which will lead you to be deficient in some of your essential amino acids... or if your overall intake of protein is insufficient to meet a bodies obligate requirements (the protein needed for
basal body functions). Otherwise, most will get all of their essential amino acids through the different foods they eat and will not suffer from protein deficiency.
BUT, that is for the average, non-active person who wants to remain sloathful and non-muscular. For anything more (eg: from the somewhat active everyday individual right through to your bodybuilder), relying on incomplete proteins as a major protein source adds a 'rate limiting step' to your bodies athletic and anabolic potential. Anything that increases the rate of protein turnover in your muscles will increase your requirements, and if you do not fill this requirement your body will not have all those amino acids readily available to help with muscle development and recovery. So it means that you are not going to be able to maintain or build muscle as efficiently or perform althletically as efficiently.
Anyway - in my opinion, there is no reason not to count that protein from your yoghurt. The protein in yoghurt is complete, and is pretty good in terms of conversion/efficiency (as it is a milk product - and is therefore whey & casein). But I would not rely on it as a sole source of protein in a meal... It just is not going to offer you enough. So, my problem with Mikah counting the yoghurt in her diet as a protein was that it was the ONLY source of complete protein for two of her meals. She would be MUCH better off combining it with something such as cottage cheese, so she got most of her protein from a much better source, and counted the yoghurt protein on top of this.
