Story at-a-glance

• Ashton Kutcher recently disclosed he suffered pancreatic problems brought on by following an all-fruit diet adopted in preparation to play the character of Steve Jobs in the upcoming film “Jobs.” Steve Jobs died of pancreatic cancer in 2011
• Fruits are loaded with antioxidants, vitamins and minerals, which is why eating a small amount of them is fine for healthy people. However, many benefit by restricting their fruit intake due to its high fructose content
• Research suggests fructose may have a particularly significant impact on pancreatic cancer, as pancreatic cancer cells have been shown to use fructose for cell division, speeding up the growth and spread of the cancer
• As a general guideline, I recommend limiting your total fructose consumption to 25 grams of fructose per day. 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
