some products with high fructose

 

How much is too much?

The list below shows how much sugar, mostly in the form of high fructose corn syrup, is in each of these single servings.

Sunkist soda: 10 1/2 teaspoons of sugar

Berkeley Farms low-fat yogurt with fruit: 10 teaspoons of sugar

Mott's applesauce: 5 teaspoons of sugar

Slim-Fast chocolate cookie dough meal bar: 5 teaspoons of sugar

1 tablespoon ketchup: 1 teaspoon of sugar

Hansen's Super Vita orange-carrot Smoothie: 10 teaspoons of sugar

Soda is no longer an innocent indulgence for children

Most sodas now contain high fructose corn syrup.....some of the facts and data about this harmful ingrediant are as follows

High-fructose corn syrup is produced by milling corn to produce corn starch then processing that corn starch to yield corn syrup that is almost entirely glucose, and then adding enzymes that change the glucose into fructose. The resulting syrup (after enzyme conversion) contains approximately 90% fructose and is HFCS 90. To make the other common forms of HFCS (HFCS 55 and HFCS 42) the HFCS 90 is mixed with 100% glucose corn syrup in the appropriate ratios to form the desired HFCS syrup. The enzyme process that changes the 100% glucose corn syrup into HFCS 90 is as follows:

  1. Cornstarch is treated with alpha-amylase to produce shorter chains of sugars called oligosaccharides.
  2. Glucoamylase breaks the sugar chains down even further to yield the simple sugar glucose.
  3. Glucose isomerase converts glucose to a mixture of about 42% fructose and 50–52% glucose with some other sugars mixed in.

While inexpensive alpha-amylase and glucoamylase are added directly to the slurry and used only once, the more costly glucose-isomerase is packed into columns and the sugar mixture is then passed over it, allowing it to be used repeatedly until it loses its activity. This 42–43% fructose glucose mixture is then subjected to a liquid chromatography step where the fructose is enriched to approximately 90%. The 90% fructose is then back-blended with 42% fructose to achieve a 55% fructose final product. Most manufacturers use carbon absorption for impurity removal. Numerous filtration, ion-exchange and evaporation steps are also part of the overall process

Consumers may think that because it contains fructose--which they associate with fruit, which is a natural food--that it is healthier than sugar. A team of investigators at the USDA, led by Dr. Meira Field, has discovered that this just ain't so.

Sucrose is composed of glucose and fructose. When sugar is given to rats in high amounts, the rats develop multiple health problems, especially when the rats were deficient in certain nutrients, such as copper. The researchers wanted to know whether it was the fructose or the glucose moiety that was causing the problems. So they repeated their studies with two groups of rats, one given high amounts of glucose and one given high amounts of fructose. The glucose group was unaffected but the fructose group had disastrous results. The male rats did not reach adulthood. They had anemia, high cholesterol and heart hypertrophy--that means that their hearts enlarged until they exploded. They also had delayed testicular development. Dr. Field explains that fructose in combination with copper deficiency in the growing animal interferes with collagen production. (Copper deficiency, by the way, is widespread in America.) In a nutshell, the little bodies of the rats just fell apart. The females were not so affected, but they were unable to produce live young.

An overweight America may be fixated on fat and obsessed with carbs, but nutritionists say the real problem is much sweeter -- we're awash in sugar.

Not just any sugar, but high fructose corn syrup.

The country eats more sweetener made from corn than from sugarcane or beets, gulping it down in drinks as well as in frozen food and baked goods. Even ketchup is laced with it.

Almost all nutritionists finger high fructose corn syrup consumption as a major culprit in the nation's obesity crisis. The inexpensive sweetener flooded the American food supply in the early 1980s, just about the time the nation's obesity rate started its unprecedented climb.
