Dr Johannes Coy is a world-renowned scientist whose research focuses on the health benefits of sugar awareness. Dr Coy has made a number of important genetic discoveries which change our understanding of cancer and nutrition and make him the leading expert on sugars.
Book: Fit with Sugar, by Dr Johannes Coy
Dr Coy has written several books about cancer nutrition. His latest book, Fit with Sugar, is now available. In this book, you’ll discover the evolutionary role of sugar in the human body. Consuming too much conventional sugar isn’t good for our health, but with the right sugars, we can stop cell ageing, keep the brain fit, protect against diseases and switch on fat burning. Find out how you can maintain physical and mental performance using natural low- glycaemic sugars and sugar substitutes. The book includes many delicious recipes for cakes, snacks and desserts, so you can implement a sugar-conscious diet easily and intelligently, without giving up sweet treats.

The beneficial effects of D-allose and D-allulose on the brain under ischemic stroke and obese-insulin resistant conditions: evidence from in vitro to clinical studies
This study reviews current evidence on the neuroprotective effects of rare sugars, particularly D-allose and D-allulose, under both normal and pathological brain conditions such as ischemic stroke and obesity-induced insulin resistance. In vitro findings show that these sugars reduce oxidative stress, inflammation, and neuronal apoptosis by modulating pathways like Gal-3/TLR4 and the unfolded protein response (UPR). In vivo animal models confirm these benefits, with improvements in cognitive and motor function, reduced brain infarct size, and enhanced insulin signaling in the hippocampus. A supporting clinical fMRI study also suggests that allulose uniquely influences brain reward responses and satiety compared to other sweeteners. Overall, the study highlights the therapeutic potential of rare sugars for brain-related disorders and calls for further clinical investigation.
Naturally occurring rare sugars are free radical scavengers and can ameliorate endoplasmic reticulum stress
Because of potential use of naturally occurring rare sugars as sweeteners, their effect on superoxide (SO), hydroxyl and peroxyl radicals and endoplasmic reticulum (ER) stress was examined in human coronary artery endothelial cells. SO generation was measured using the superoxide-reactive probe 2-methyl-6-(4-methoxyphenyl)-3,7-dihydroimidazo[1,2-A]pyrazin-3-one hydrochloride chemiluminescence. Phycoerythrin fluorescence based assay was used to monitor scavenging activity of sugars in the presence of hydroxyl or peroxyl radical generators [CuSO4 and azobis (2 amidinopropane) hydrochloride respectively]. Measurements were made in relative light units (RLU). ER stress was measured with an ER stress-sensitive secreted alkaline phosphatase (SAP) assay and by Western blot analysis of the expression and phosphorylation of key proteins in the unfolded protein response, namely CHOP47, eIF2α and JNK1. D-Glucose (27.5 mM) increased SO generation (5536 ± 283 vs. 2963 ± 205 RLU in controls; p < 0.0007) and decreased SAP secretion (73411 ± 3971 vs. 101749 ± 7652 RLU in controls; p < 0.005) indicating ER stress. Treatment of cells with 5.5 or 27.5 mM of D-allulose, D-allose, D-sorbose and D-tagatose reduced SO generation (all p < 0.05). This could not be attributed to inhibition of cellular uptake of dextrose by the rare sugars tested. In a cell free system, all four rare sugars had significantly more SO, hydroxyl and peroxyl radical scavenging activity compared to dextrose (all p < 0.01). Treatment of cells with rare sugars reduced ER stress. However, unlike other three rare sugars, D-sorbose did not inhibit tunicamycin-induced eIF2α phosphorylation. Naturally occurring rare sugars are free radical scavengers and can reduce ER stress.
