Fruit Juices Can Raise The Blood Sugar Levels of Type 2 Diabetics

If you suffer from type 2 diabetes fruit juices could be hazardous to your health, creating a rapid surge of blood glucose and insulin. That insulin can drive blood glucose into your cells for storage causing a rapid and dangerous drop in blood glucose levels.


Fruit juices can cause your blood sugar to skyrocket!

Juice, as it’s a concentrated form of fruit, is high in sugar. A typical eight-ounce glass of orange juice has about 28 grams of sugar–about the same amount as in Coca Cola. High sugar intake is correlated with diabetes risk and poor diabetes blood sugar control.

Dozens of studies have shown us that fruits and vegetables are the cornerstones of a healthy diet.

However, the same may not hold true when it comes to your morning apple juice or orange juice, for that matter.

Americans often turn to juice as a healthy alternative to soda and other sweetened drinks. In fact, the average American drinks approximately 11 gallons, or 177 cups of juice a year, according to the World Development Indicators Database.

But new data suggests that for women at least, juice consumption may contribute to an increased risk of diabetes.

The study, recently published in the journal Diabetes Care, looked at data from the Nurses’ Health Study, which has followed the health and lifestyles of more than 70,000 women over an 18-year period.

The authors found an association between fruit and fruit juice intake and the likelihood of developing type 2, or “adult onset” diabetes.

Those women who consumed an average of one or more servings of fruit juice a day were 18 percent more likely to develop type 2 diabetes, whereas those who consumed three or more servings of whole fruits or one serving of green leafy vegetables had significantly lower rates of the disease

Research now shows that in addition to soft drinks, juice is now a contributing factor to the onset of type-2 diabetes.

Research shows that commercially produced fruit juices, regarded by many as a healthy way to start the day, raise the odds of a form of diabetes linked to poor diet and obesity by up to a quarter.

Fruit juice, in particular, is a highly concentrated source of fruit sugar. This can raise your blood sugar quickly, and that’s why juice is not recommended for people with type 2 diabetes. Individuals with high triglycerides should avoid fruit juice as well, as its concentrated simple sugars can raise triglyceride levels even higher. Fruit drinks — not to be confused with 100 percent juices — are an even worse choice because they contain added sugars and less nutrition

A study that was recently released by Tulane University has found a link between the consumption of fruit juices and the development of type 2 diabetes. Ironically, the study also showed that one of the best ways to prevent the development of the disease is to consume a diet that is rich in whole fruits and vegetables!

According to the study, eating an additional three servings of fruit per day can reduce the risk of developing diabetes by up to 18%. Similarly, a single serving of green, leafy vegetables can reduce the risk by 9%. However, just one daily serving of fruit juice can increase the risk of developing diabetes by 18%!.

Why do fruit juices increase the risk of developing diabetes?

A glass of juice, whether fresh-squeezed or not, has about eight full teaspoons of sugar per eight-ounce glass. This is about as much sugar as a can of soda.

When the sugar is consumed in its natural form, with the whole fruit, the fiber in the orange tends to slow the absorption of sugar and thus prevents a spike in your insulin levels. When you drink just the juice, it’s too much sugar, all at once, for your system to handle.

Eating whole pieces of fruit however, cuts the likelihood of developing the disease which affects millions of people worldwide.

It is thought the lack of fiber in juices may cause dangerous spikes in blood sugar levels, according to researchers from the Harvard Medical School in the U.S.

A glass of fruit juice contains almost as much carbohydrates as a glass of sugar filled coca cola. The fiber in fruit and vegetables slows down this conversion. When you juice, you remove this essential fiber and the carbohydrates in the fruit and vegetable juice convert more quickly to blood glucose. Consider the carbohydrates in fruit juice in your meal planning. There are 15 grams of carbohydrates on average in three to four ounces of fruit juice.


Due to the fact that the natural enzymes of these juices have been destroyed during processing, all that remains is the acid part of the juice.

Store bought juices have lost most of their nutrient content through modern processing methods like pasteurization, where the precious enzymes and nutrients are destroyed due to the high temperatures. This is in addition to the fact that juices start to lose their nutritional content soon after they are pressed from the fruit due to oxygenation.

Whole fruit has fiber and all sorts of goodies hiding in the pulp and skin. Fruit juice does NOT have these. What fruit juice does have is SUGAR.

Yes, even ‘natural’ sugar from fruit is the same as the sugar in that candy bar. Your body does not know the difference.
The fiber etc in the whole fruit slows the down the absorbing of the sugar. Drinking the juice is not a whole lot different than letting your kid drink a Coke.

Dr. David Ludwig at Children’s Hospital in Boston states that juice and sodas are essentially the same in that they have very high amounts of sugar.  The point to remember is that sugar is sugar whether it is table sugar or fruit sugar.

Some will argue that it’s fruit and that alone should make it healthy. While both whole fruits and vegetables are an important part of a healthy diet, it’s a blatant mistruth to say they’re all good for you when clearly they are not.

Avoid orange juice!

Orange juice is marketed as a simple, healthy, and natural food; in fact, it’s heavily processed and contains several added chemicals.

Just one glass of orange juice a day could significantly increase the risk of diabetes.

Orange juice is almost the worst thing you can ingest if you suffer from type 2 diabetes unless you need to bring your sugar up. Orange juice is loaded with carbohydrates and they are all sugar carbohydrates from the fructose. It goes almost immediately into your bloodstream and raises your sugar very high, very fast.

It may come as a surprise to learn that what you find in a carton of 100% pure, not from concentrate orange juice is nothing like what you’d get if you squeezed an orange into a glass in your own kitchen. Instead, many popular orange juice brands use a chemical process to create juice that tastes and smells like oranges!

Alissa Hamilton J.D, PhD, a Food and Society Policy Fellow with the Institute for Agriculture and Trade Policy (IATP), explains the ins and outs of mass-produced juice in her book, Squeezed: What You Don’t Know About Orange Juice.

Mrs.. Hamilton says the production of orange juice has become highly mechanized and involves the input of chemists and engineers.

Interviewed on February 22, 2009 by Boston Globe writer Debra First, Ms. Hamilton said, “In the process of pasteurizing, juice is heated and stripped of oxygen, a process called deaeration, so it doesn’t oxidize. Then it’s put in huge storage tanks where it can be kept for upwards of a year. It gets stripped of flavor-providing chemicals, which are volatile.” After this processing, the juice essentially tastes like water.

The juice makers then call on the expertise of flavor and fragrance companies, the same ones that create perfume, to bring back the orange taste. So-called flavor packs are created through re-engineering; “they’re technically made from orange-derived substances, essence, and oils,” says Ms. Hamilton. “Flavor companies break down the essence and oils into individual chemicals and recombine them.”

Avoid apple juice!

While an apple a day is supposed to be the key to good health, too much apple juice may be a contributing factor to diabetes and its associated complications. While apples and other whole fruits are full of fiber that helps keep the sugar in the fruit from being absorbed into the blood stream too quickly, the sugar in apple juice and other fruit juices is much more concentrated and can cause blood glucose levels to rise too quickly. In fact, research has shown that drinking apple juice or other fruit juices is related to the development of diabetes in women.

Tip: If you want to drink juice consider having it during a meal with fiber. The fiber will slow down the absorption of sugar in the blood.

Drink fresh squeezed fruit and vegetable juices

Fresh fruit and vegetable juices are extremely beneficial in treating type-2 diabetes due to their high concentration of natural enzymes, and their ability to flush out toxins from the bloodstream.

Fresh juices are loaded with vitamins and minerals, especially the all- important plant- based Omega-3 linolenic acid, and precious live plant enzymes.
