    Plant protein spares kidneys






    Plant protein spares kidneys

    Growing numbers of people suffer from chronic kidney disease. Risk factors include diabetes, high blood pressure and – as you age – a diet containing large amounts of protein. People who want to protect their kidneys are usually advised to eat less protein. Canadian researchers suspect however, that a protein-rich diet is not always bad for the kidneys, as long as the proteins come from plants rather than animals.

    Healthy kidneys filter the blood and remove toxic compounds from the body via the urine. But aging and disease can damage the kidneys and reduce their functioning, resulting in higher levels of protein in the urine and more creatinine [the waste product from creatine] in the blood. In the early stages of chronic kidney disease, the best remedy is to reduce intake of all nutrients that put stress on the kidneys. The diet recommended for someone with kidney problems, or who wants to protect their kidneys, is exactly the opposite of a power athlete's diet. It contains little protein.

    The Canadians, working at the University of Manitoba, are looking for an alternative way of protecting the kidneys, and think they've come up with one: plant proteins. These place less strain on the kidneys, the researchers discovered when they did experiments on rats with damaged kidneys. The technical name for these animals is Han:SPRD-cy rats.

    The lab animals were given the same feed, containing 17 percent protein, for a period of eight weeks. The kind of protein in each feed differed: one group got casein, a milk-based protein; the other groups got hemp, pea or soya protein. Some of the plant proteins contained much lower concentrations of some amino acids than found in casein, so the researchers supplemented these.

    At the end of the eight weeks, the researchers measured the effects of the different types of protein on the kidneys. The kidneys of the rats that had been given hemp and soya protein weighed less – a positive sign.

    The amounts of creatinine in the blood and protein in the urine were also lower in the hemp and soya groups. In fact, the scores for the soya group were the same as those of the control group rats with healthy kidneys.

    Makes sense. Plant protein is absorbed much more slowly than casein, about half as fast. So there would be a reduced 'spike' of amino acids in the blood, meaning less chance that the kidneys would be periodically overloaded.

    Pea, hemp and soy protein intestinal absorption rates are all around 3.5 grams/hr, casein is 6-7 grams/hour (in humans).

    so soy protein is better for your health and slower digesting?

    Maybe Soya helps with weight loss as well.

    I have started using Soya protein isolate from these guys Pro-10.com Uk based and cheap Soay is really low carb as well
