Saturated fat does not clog the arteries: coronary heart disease is a chronic inflammatory condition, the risk of which can be effectively reduced from healthy lifestyle interventions | British Journal of Sports Medicine

http://bjsm.bmj.com/content/51/15/1111



"Coronary artery disease pathogenesis and treatment urgently requires a paradigm shift. Despite popular belief among doctors and the public, the conceptual model of dietary saturated fat clogging a pipe is just plain wrong."

Evidence That Intermittent, Excessive Sugar Intake Causes Endogenous Opioid Dependence - Colantuoni - 2002 - Obesity - Wiley Online Library

Discussion: Repeated, excessive intake of sugar created a state in which an opioid antagonist caused behavioral and neurochemical signs of opioid withdrawal. The indices of anxiety and DA/ACh imbalance were qualitatively similar to withdrawal from morphine or nicotine, suggesting that the rats had become sugar-dependent.

Dietary Carbohydrates Impair Healthspan and Promote Mortality: Cell Metabolism

http://www.cell.com/cell-metabolism/fulltext/S1550-4131(17)30562-4


The prospective cohort study, named PURE, found that in >135,000 participants from 18 countries, nutritive carbohydrates increase human mortality, whereas dietary fat reduces it, requesting a fundamental change of current nutritional guidelines. Experimental evidence from animal models provides synergizing mechanistic concepts as well as pharmacological options to mimic low-carb or ketogenic diets.

Nutrition and Health – The Association between Eating Behavior and Various Health Parameters: A Matched Sample Study

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3917888/



"Our results showed that a vegetarian diet is associated with poorer health (higher incidences of cancer, allergies, and mental health disorders), a higher need for health care, and poorer quality of life. Therefore, public health programs are needed in order to reduce the health risk due to nutritional factors."

Effects of Dietary Fructose Restriction on Liver Fat, De Novo Lipogenesis, and Insulin Kinetics in Children With Obesity - Gastroenterology

http://www.gastrojournal.org/article/S0016-5085(17)35685-8/fulltext


"Conclusions
Short-term (9 days) isocaloric fructose restriction decreased liver fat, VAT, and DNL, and improved insulin kinetics in children with obesity. These findings support efforts to reduce sugar consumption. ClinicalTrials.gov Number: NCT01200043."

Associations of fats and carbohydrate intake with cardiovascular disease and mortality in 18 countries from five continents (PURE): a prospective cohort study - The Lancet

http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)32252-3/fulltext




"Interpretation

High carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality, whereas saturated fat had an inverse association with stroke. Global dietary guidelines should be reconsidered in light of these findings."

Study Puts Smart Drugs Back in Spotlight | Adolescent Medicine | JAMA | The JAMA Network

"A group of 39 highly rated male members of the German Chess Federation were enlisted to play more than 3000 15-minute games against computers matched to their skill levels while taking modafinil, methylphenidate, or caffeine. The researchers reported that players taking modafinil and methylphenidate won more games overall, though they pondered their moves longer, causing them to sometimes lose on time."
"The positive association surprised Lieb. “Our hypothesis [had been] that it’s not possible to enhance subjects who are already working at top performance,” he said."

Press-pulse: a novel therapeutic strategy for the metabolic management of cancer | Nutrition & Metabolism | Full Text

"Conclusions

Optimization of dosing, timing, and scheduling of the press-pulse therapeutic strategy will facilitate the eradication of tumor cells with minimal patient toxicity. This therapeutic strategy can be used as a framework for the design of clinical trials for the non-toxic management of most cancers."
