The Raisins and the Tartaric Acid

        A few years back, the American Society for the Prevention of Cruelty to Animals and the Animal Poison Control Center posted an alert for pet owners that raisins can cause kidney failure in dogs. It was never determined what the toxic element in raisins was that was responsible for these dog deaths. However, it raises the question as to whether or not raisins are good or bad for humans. Some say that raisins are too high in sugar to be considered healthy for human consumption. About a half a cup of raisins has 59 grams of sugar. The sugar in raisins is fructose, an organic sugar that is present in all fruits.
        In that same half a cup of raisins, there are 4 grams of fiber. We all know the benefit of fiber in our diets as an aid in proper digestion and elimination. Fiber rich diets also improve cholesterol levels and help control weight. The recommended amount of fiber for adults according to most experts is between 25 and 35 grams of fiber per day. So, that little half a cup of raisins contributes about one sixth of all the fiber you need in a day. Raisins also contain tartaric acid, which works with your liver and colon to strengthen them and aid in digestion, partly due to its mild laxative effect. It has also been discovered that tartaric acid is good for asthma as it causes the lungs to dilate inducing a cough response. Raisins are one of the few fruits that contain tartaric acid besides apples and grapes and it is also present in wine. Of course, too much of a good thing can be bad. 500 grams of tartaric acid is considered a lethal dose for the average person. That half of cup of raisins has about 3 grams of tartaric acid.
