Article Abstract
Consumption of dietary protein has been shown to elicit the strongest satiety among macronutrients. Protein intake-induced feeding inhibition (PIFI) plays a critical role in the maintenance of nutrition homeostasis. Here, we present an optogenetic pre-feeding protocol for studying the neural mechanisms underlying PIFI in Drosophila. We describe steps for preparing and loading flies into feeding chambers, quantifying food consumption, estimating excretion levels following the feeding test, and evaluating the inhibitory effect of dietary protein. For complete details on the use and execution of this protocol, please refer to Li et al. and Sun et al..

Non-nutritive sweetener (NNS) administration has been proven to be likely related to cardiovascular disease (CVD) risk. However, the effect of saccharin (SA), a major daily consumed NNS, on atherosclerosis (AS) progression remains insufficiently elucidated. In this study, free drinking water plus 0.

Plastic degradation by insects often causes oxidative stress-induced intestinal damage, which harmed the intestinal function to limit plastic degradation. Herein, we investigated the potential of spirulina supplementation to alleviate intestinal damage and affect polystyrene degradation in Zophobas atratus larvae. Compared to wheat bran, spirulina supplementation more effectively reduced polystyrene-intake induced intestinal tissue degradation and epithelial shedding.

The increasing prevalence of processed foods has significantly elevated dietary phosphorus intake globally, posing a risk to skeletal health. Elevated serum phosphate promotes parathyroid hormone (PTH) release, leading to bone resorption and decreased bone formation. : This study investigated the influence of chronically elevated phosphorus intake on bone structure in rats with normal renal function, focusing on the Receptor Activator of Nuclear factor Kappa-B (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) pathway and its related components, leucine rich repeat containing G protein-coupled receptor 4 (LGR4), and R-spondins (RSPOs).

Alcohol-associated liver disease (ALD) is characterized by the reduction of hepatic nicotinamide adenine dinucleotide (NAD), which exacerbates hepatic steatosis. The present study was conducted to investigate the protective role of nicotinamide (NAM), a foodborne precursor of NAD biosynthesis, in ALD. C57BL/6N mice were employed to establish the ALD model and were administered NAM by gavage.
