Fruit Juice and Cancer By Mrs Vera West

     We have been told that fruit juice is good for one, packed with nutrients, compared to say, soda. But, is there is another perspective to this? What about the sugar content? Sure, its fructose, but is that necessarily better for one? Here are the results of a recent article from the British Medical Journal showing that fruit juice can increase cancer risk! As this claim is surprising I will not mess around with quoting newspapers, but go straight to the abstract, which is readable:

“Abstract
Objective To assess the associations between the consumption of sugary drinks (such as sugar sweetened beverages and 100% fruit juices), artificially sweetened beverages, and the risk of cancer. Design Population based prospective cohort study. Setting and participants Overall, 101?257 participants aged 18 and over (mean age 42.2, SD 14.4; median follow-up time 5.1 years) from the French NutriNet-Santé cohort (2009-2017) were included. Consumptions of sugary drinks and artificially sweetened beverages were assessed by using repeated 24 hour dietary records, which were designed to register participants’ usual consumption for 3300 different food and beverage items. Main outcome measures Prospective associations between beverage consumption and the risk of overall, breast, prostate, and colorectal cancer were assessed by multi-adjusted Fine and Gray hazard models, accounting for competing risks. Subdistribution hazard ratios were computed. Results The consumption of sugary drinks was significantly associated with the risk of overall cancer (n=2193 cases, subdistribution hazard ratio for a 100mL/d increase 1.18, 95% confidence interval 1.10 to 1.27, P<0.0001) and breast cancer (693, 1.22, 1.07 to 1.39, P=0.004). The consumption of artificially sweetened beverages was not associated with the risk of cancer. In specific subanalyses, the consumption of 100% fruit juice was significantly associated with the risk of overall cancer (2193, 1.12, 1.03 to 1.23, P=0.007). Conclusions In this large prospective study, the consumption of sugary drinks was positively associated with the risk of overall cancer and breast cancer. 100% fruit juices were also positively associated with the risk of overall cancer. These results need replication in other large scale prospective studies. They suggest that sugary drinks, which are widely consumed in Western countries, might represent a modifiable risk factor for cancer prevention.”

     It appears to be the sugar content of fruit juices which causes this. It is far better to eat the whole fruit, but even here, only in moderation. This is interesting since this example shows that something can be good in one respect, but bad in another, and hence overall bad. Sad.
