Fructose (naturally found in fruit) breaks down into a variety of waste products that are bad for your body, one of which is uric acid. As it turns out, uric acid drives up your blood pressure.

Thanks to Dr. Johnson’s research, we now know that fructose generates uric acid within minutes of ingestion. High levels of uric acid are normally associated with gout, but it has been long known that people with high blood pressure and kidney disease, and people who are overweight, often have elevated uric acid levels.

It was thought this increased uric acid resulted from the disease, but it appears now that it may have been CAUSING it!

Not surprisingly, uric acid levels have been increasing for the past hundred years.

When your uric acid level exceeds about 5.5 mg per dl, you have an increased risk for a host of diseases, including:

  * Hypertension/High Blood Pressure
  * Kidney disease
  * Insulin resistance, obesity, and diabetes
  * Fatty liver
  * Elevated triglycerides, elevated LDL, and cardiovascular disease
  * For pregnant women, even preeclampsia

Is Fruit Bad?

If you are craving something sweet, your best bet is to reach for an apple or a pear. And if you give yourself a sugar holiday for even a couple of weeks, you will be amazed at how much those cravings will decrease. But be sure and count the grams of fructose and keep your total fructose from fruit below 15 grams per day as you are sure to consume plenty of "hidden" fructose in the other foods you will be eating.

Recommended Fructose Allowance:

As a standard recommendation, I strongly advise keeping your TOTAL fructose consumption below 25 grams per day.

However, for most people it would actually be wise to limit your fruit fructose to 15 grams or less, as it is virtually guaranteed you will consume “hidden” sources of fructose from most beverages and just about any processed food.

Fifteen grams of fructose is not much -- it represents two bananas, one-third cup of raisins, or just two Medjool dates!

Since the average 12-ounce can of soda contains 40 grams of sugar, at least half of which is fructose, this can of soda ALONE would exceed your daily allotment of 15 grams -- plus it offers you absolutely nothing nutritive, only empty calories.

Reducing sugar in your diet can be tough. After all, sugar is just as addictive as cocaine!

In his book, The Sugar Fix, Dr. Johnson includes detailed tables showing the content of fructose in different foods -- an information base that isn’t readily available when you’re trying to find out exactly how much fructose is in various foods. I encourage you to pick up a copy of this excellent resource.

You can use the table below to help you count your fructose grams:
