Wheat grass juice

I am all in favor of keeping it natural; natural foods, natural herbs all things natural. However, let's be real. Face it-tornadoes and poison ivy are also natural. So, once in a while there is a problem with natural. Just this week there was a gentleman who tried wheat grass juice for the first time. As it happened, this man is 85 years old with chronic kidney problems (he sees a nephrologist regularly) and diabetes. His daughter (who is into health foods) offered him a small cup of fresh wheat grass juice. The next thing he knew, he became dizzy and weak. He checked his blood sugar with a glucometer (or blood glucose meter) and discovered that it was off the charts high. Possibly this was due to a high content of carbohydrates and potassium affecting his blood sugar and kidneys. Moral of the story? Always be careful in selecting new foods, nutraceuticals and supplements especially if you have chronic illnesses.
