Beliefs about credible hypotheses of dietary causes of disease still need well-defined mediators to test for logical proof or disproof. We know that food energy causes transient postprandial oxidative insults that may not be fully reversible. Also, eating vitamin-like 18-carbon polyunsaturated fatty acids (PUFA) in foods maintains the 20- and 22-carbon highly unsaturated fatty acids (HUFA) in tissues. Tissue HUFA form hormone-like mediators that each amplify transient postprandial insults into fatal inflammatory, thrombotic and arrhythmic events in cardiovascular disease, a major preventable cause of death. Similar diet-based amplified events may also occur in other inflammatory proliferative disorders including cancer, dementia, arthritis and asthma. Puzzling paradoxes come from fragmented views of this situation which convey incomplete knowledge in oversimplified messages. Tools now exist to demonstrate successful prevention of two fatal food imbalances with credible dietary preventive interventions, but organizers and financers to help gather the evidence remain unknown. The overall evidence accumulated about diet, disease and death may be nearing a paradigm shift in which prior observed facts remain while beliefs about their accepted interpretation change.

Background: Postprandial hyperglycemia induces expression of inflammatory cytokines including tumor necrosis factor (TNF), which promotes the onset of type 2 diabetes and cardiovascular diseases. In this study, we investigated whether a transient high-glucose culture enhanced sustained expression of TNF, or whether the induction is associated with histone acetylation, and bromodomain protein containing protein 4 (BRD4), which binds acetylated histone, in human juvenile macrophage-like THP-1 cells.
Methods: THP-1 cells were cultured in medium with high-glucose in the presence or absence of (+)-JQ1, an inhibitor of bromodomain and extra-terminal domain family, for 24 h (day 0).

Objective: The control of energy balance involves neural circuits in the central nervous system, including AGRP neurons in the arcuate nucleus of the hypothalamus (ARC). AGRP neurons are crucial for energy balance and their increased activity during fasting is critical to promote feeding behavior. The activity of these neurons is influenced by multiple signals including those acting on G-protein coupled receptors (GPCR) activating different intracellular signaling pathways.

Background: Postprandial sleepiness refers to the state of excessive drowsiness that occurs after consuming a meal. This transient phenomenon is experienced by many individuals, often leading to decreased productivity and impaired cognitive performance. This study examined the effect of a whole-food plant-based (WFPB) diet on postprandial sleepiness.

Several health-beneficial effects are associated with intake of medium-chain triacylglycerol (MCT); however, the underlying mechanisms are unknown. Furthermore, it remains uncertain whether the acute metabolic effects of MCT differ between lean individuals and individuals with obesity-and whether these effects are sustained following chronic intake. This study aimed to elucidate the postprandial physiological and metabolic effects of MCT before and after 8 days intake compared with intake of energy-matched triacylglycerol consisting of long-chain fatty acids (long-chain triacylglycerols, LCT) using a randomized cross-over design in lean individuals ( = 8) and individuals with obesity ( = 8).
