Each of us sees a part of the complex puzzle and may assure our colleagues that, in fact, we have solved the entire riddle for how nutrition relates to various disease processes.
Are D-fructose and L-fructose anomers, epimers, diastereomers, enantiomers, or not stereoisomers?
The scientific and medical communities have gone down the road of speculating cause and effect without conclusive evidence many times. We blamed salt consumption for contributing to hypertension [ 1 ], yet recent evidence suggests that this relationship is far more complex [ 23 ]. We blamed dietary cholesterol for contributing to heart disease and warned a generation of Americans to avoid eating egg yolks, although that advice has subsequently been found to lack scientific justification [ 4 ].
With the issue of sweeteners, the scientific community faces the problem of trying to offer advice without seeing the totality of the picture, much like the blind men approaching the elephant.

It is time to pause and try to see the entire elephant. Added sugars are among the most controversial and hotly debated topics in all of nutrition [ 5678910111213141516171819202122 ]. Consumption of added sugars has been associated with increased risk of obesity [ 232425 ] as well as increased risk factors for cardiovascular disease CVD [ 26 ], including dyslipidemia [ 2728 ], elevated blood pressure [ 202930 ], diabetes [ 213132 ], non-alcoholic fatty liver disease [ 3334 ], and even cognitive decline [ 35 ] and cancer [ 3637 ].
Data to support these assertions, however, have been challenged consistently. Often these assertions have been based on research trials which provide added sugars in dosages well above those typically found in human consumption supraphysiological [ 12 ].
Studies comparing pure fructose to pure glucose, neither which is consumed to any appreciable degree in the human diet, have also been extrapolated to human nutrition [ 3839 ]. Speculation about chronic conditions based on acute data has frequently been employed [ 40 ]. Theoretical models, epidemiologic studies which do not establish cause and effect [ 313241 ] or data from animal models which can translate poorly to humans particularly in the areas of nutrition, metabolism, and behavior have further clouded the debate [ 42434445 ].
Further controversy has arisen from failure by investigators to clearly acknowledge the limitations of their studies, and misinterpretation or overly simplistic interpretations by media or failure to acknowledge the totality of the evidence often for political reasons or recognition.
A vast amount of literature has been generated, particularly over the past decade, exploring potential linkages between added sugars and various health related conditions.
What is the relationship between D-glucose and D-fructose?
The purpose of this review is to survey some of the modern science, particularly from high quality research trials such as randomized controlled trials, systematic reviews and meta-analyses, in an attempt to provide some clarity in this controversial area.
Literature reviews in this manuscript were drawn from articles cited in the World Health Organization report commissioned by Te Morenga et al. Levels of Evidence Any discussion of health consequences related to added sugars and NNSs must take into account levels of evidence. Now we know the different types of sugars -- is one sugar better or worse for us? From that perspective, other than a slight benefit from lactose, all the sugars are going to cause dental caries and will generally provide the same amount of kilojoules per gram.
While different sugars have a slightly different effect in the body, there's no one 'hero' sugar.
Whereas fructose will have the least effect on glucose and insulin, but it will raise triglyceride levels. Nobody consumes pure fructose. This means that pitting one sugar against the other is not the right mentality to have towards sugar.
Instead, see added sugar that is, not whole fruit as a 'sometimes' food. There's no need to avoid all sugars.
The WHO guidelines make that quite clear," Barclay said. It's sugar-sweetened beverages -- whether that's soft drink, flavoured mineral waters and energy drinks -- which shouldn't be daily foods or drinks.D-Glucose to D-Fructose and D-Mannose
Fruit Do you avoid fruit because it's high in fructose? Barclay urges people to move away from this attitude.
The minimum recommended amount per day is two and anyone who suggests it contributes to obesity is wrong. We're eating so little of fruit, how could it possibly be contributing to obesity when two-thirds of the population are overweight or obese. It's an entirely unnecessary focus," Barclay said.
