Fructose – a simple sugar found in fruit

Why Large Amounts of Fruit May Not Be Healthy
Fruits are loaded with healthy antioxidants, vitamins and minerals, which is why eating them in moderation is fine for healthy people. However, many benefit by restricting their fruit intake.            avocado

Fructose, a simple sugar found in fruit, is preferentially metabolized to fat in your liver, and eating large amounts has been linked to negative metabolic and endocrine effects. So eating very large amounts – or worse, nothing but fruit – can logically increase your risk of a number of health conditions, from insulin and leptin resistance to cancer.

While people are becoming increasingly aware of the connection between excessive fructose consumption and obesity and chronic disease, many forget that fruit is a source of fructose as well.

Many tend to believe that as long as fruit is natural and raw they can have unlimited quantities without experiencing any adverse metabolic effects.

Eliminating processed foods and soda – which are loaded with high fructose corn syrup – and replacing it with an all-fruit diet is likely not going to improve your health.

It’s important to consider ALL sources of fructose, and to try to limit your total consumption if you want to optimize your health.

Granted, fruits contain beneficial dietary fibers, antioxidants, vitamins and minerals, which is why they’re an important part of a healthy diet – as long as they’re eaten in moderation.

I believe most people would benefit by replacing the fruit with 50-70 percent of their calories from healthy fat. You also need moderate amounts of high quality protein.

An all-fruit diet is essentially an all-fructose diet, and this is bound to spell disaster for your health, at least long-term.  – – – –
Your pancreas contains two types of glands: exocrine glands that produce enzymes that break down fats and proteins, and endocrine glands that make hormones like insulin that regulate sugar in your blood.
Insulin production is one of your pancreas’ main functions, used by your body to process blood sugar, and, in the laboratory, insulin promotes the growth of pancreatic cancer cells.

However, there’s more to it than that.

The research in question showed that the way the different sugars are metabolized (using different metabolic pathways) is of MAJOR consequence when it comes to feeding pancreatic cancer cells and making them proliferate. According to the authors:

“Importantly, fructose and glucose metabolism are quite different… These findings show that cancer cells can readily metabolize fructose to increase proliferation.”

The study confirms the old adage that sugar feeds cancer – a finding that Dr. Warburg received a Nobel Prize for over 90 years ago. Tumor cells do thrive on glucose and do not possess the metabolic machinery to burn fat.

However, the cells used fructose for cell division, speeding up the growth and spread of the cancer. If this difference isn’t of major consequence, then I don’t know what is. Whether you’re simply interested in preventing cancer, or have cancer and want to live longer, you ignore these facts at your own risk.

There’s reasonable cause to suspect that if your body maintains high levels of insulin, you increase the pancreatic cancer’s ability to survive and grow. In fact, researchers now believe that up to a third of all types of cancers may be caused by diet and lifestyle. So if you want to prevent cancer, or want to treat cancer, it is imperative that you keep your insulin levels as low as possible.

Should You Eliminate Fruit from Your Diet?

Short answer, no, it wouldn’t be wise to eliminate fruit entirely.

Fruit is definitely a source of fructose, and one that can harm your health if you eat it in vast quantities, but eating small amounts of whole fruits is fine if you are healthy.

In vegetables and fruits, the fructose is mixed in with fiber, vitamins, minerals, enzymes, and beneficial phytonutrients, all of which help moderate the negative metabolic effects.

However, if you suffer with any fructose-related health issues, such as insulin resistance, metabolic syndrome, heart disease, obesity or cancer, you would be wise to limit your total fructose consumption to 15 grams of fructose per day. This includes fructose from ALL sources, including whole fruit.

If you are not insulin resistant, you may increase this to 25 grams of total fructose per day on average.

If you received your fructose only from vegetables and fruits (where it originates) as most people did a century ago, you’d consume about 15 grams per day.

Today the average is 73 grams per day which is nearly 500 percent higher a dose and our bodies simply can’t tolerate that type of biochemical abuse. So please, keep your total fructose below 15-25 grams per day, depending on your current health status.

Remember the human body NEEDS healthful fats and high quality protein for proper functioning.

Exerpts from Dr Mercola “Surprising health hazards in an all fruit diet ”

“Weight shouldn’t be your only target when exercising. Body composition varies from person to person.”  Pat Lakey

” Your body shape

  • If you carry excess weight around your abdomen, that means you’re an “apple” shape.
  • Those who carry excess fat around the bottom and thighs are “pear” shaped.

Anyone who is carrying excess weight, anywhere on the body, would get health benefits from losing that weight.

But if you’re an apple shape, it’s particularly important that you take action to achieve a healthy weight.

You can do this by making lifestyle changes to improve your diet and increase your physical activity.

Remember, physical activity can improve the health of anyone who is overweight, and it’s not just a matter of burning calories: your heart, lungs and circulation will benefit too.”  NHS UK
