|Remember: If anything fructose from beverages (including juices), yet not fructose from whole fruit is a problem. In fact eating whole fruits will decrease your blood lipids and high sensitivity C reactive protein (hs-CRP) inflammation markers.|
Much to the researchers surprise, though, the same amount of fructose had significant beneficial effects on the plasma lipid levels of the healthy male and female adults (n = 14) between the ages of 18-60 years who were recruited by advertisement and underwent study procedures at the Nutraceuticals Research Group Clinic rooms at the University of Newcastle in Australia.
Since the exclusion criteria were: diagnosed hyperlipidaemia, diabetes, gastrointestinal disorders, currently on fructose/sugar restricted diet, vegan diet or weight loss program, undergone any surgical procedure for obesity, pregnant or lactating mother, taking lipid-lowering or anti-inflammatory drugs and BMI >30kg/m², the results may well be different in "sicker" individuals, but for the guys and gals who drank the three 50g "sugar" solutions on three different occasions after an overnight fast, the "negative effects" of fructose were far from being conclusive.

Furthermore, a comparison of the predictive value of different risk markers for cardiovascular disease by Folsom, et al. (2006) indicates that the hs-CRP values did not add to the prognostic value of the standard risk factors which are age, race, sex, systolic blood pressure, smoking status, diabetes and - you guessed it - total and high density lipoprotein cholesterol, which increased by almost 7% while the amount of LDL dropped by maximally 6%. Thus the LDL/HDL ratio decreased from 1.84 to 1.62. That's a 12% decrease that would be health relevant if the subjects' LDL/HDL ratio was not far away from the danger-zone (>5 | see Manninen. 1992), already. Similarly, the total cholesterol to HDL ratio dropped by -1.97 but wasn't in the danger zone before, either.
