Interestingly, he pointed a fact that if you've problem with high uric acid levels (esp. gout sufferers), you should checked your sensitivity towards fructose (the sugar in fruits). His research actually shows that high uric acid levels increase the risk of diabetes, high-blood pressure, kidney diseases and obesity.... and fructose are one of the major culprit!!!
Well, I'm not a doctor, I don't know if what Dr. Richard say it's true, but I tend to agree based on my personal experiences. I used to have gout back then, my uric acid level was waaaayyy above the limit, and after I've cleaned my diet and exercise, my uric acid level are now at a normal level -- yup one of it, I've stayed away from fruit juices a long time ago. See my earlier post on some of the figures.
Bottom line: based on scientific research, fruit juices is not as healthy as all of us think. Take it sparingly, treat is as indulgences (as in ice-cream, cakes, etc.. you can take it once a while). Best if you can avoid it altogether. If you're thirsty, grab a bottle of water, you'll be better off healthwise.
