A new study from North Carolina State University reveals that not all dietary proteins are digested the same way. The research found that specific proteins from different sources, such as soy and egg white, can be resistant to host digestion and interact with the gut microbiota in the large intestine.
A new study published in Molecular Nutrition and Food Research found that red meat consumption causes an imbalance of bacteria in the intestinal microbiota, leading to exacerbated colonic inflammation. The diets resulted in a decrease in beneficial bacterial strains and an increase in pro-inflammatory cells.
A Japanese study found that choosing the right type of meal can extend meal duration and encourage more mindful eating. Researchers discovered that traditional bento-style meals with individual components promoted longer meal times and more chewing compared to fast food.
A new study suggests that including pork in plant-forward diets makes meals more appealing and just as healthy, offering a higher protein quality score compared to plant-based proteins. The study found that meals with lean pork delivered significantly better results for satisfaction, satiety, and willingness to adopt post-trial.
A new study by University of Illinois researchers found that a balanced vegan diet has no effect on muscle protein synthesis or muscle gain compared to an omnivorous diet. Protein distribution throughout the day also made no difference in muscle building, contrary to previous assumptions.
A New Zealand study found that three-quarters of long-term vegans met daily total protein requirements, but only half met daily lysine and leucine requirements. Legumes and pulses were key contributors to overall protein and lysine intake.
A global study found that countries consuming more plant-based proteins have longer adult life expectancies, while high animal-based protein intake is linked to lower infant mortality rates.
A study at the University of Turku found that different processing methods significantly affect plant-based products' biochemical composition. Current food classification systems do not acknowledge this, which can lead to misclassification of beneficial products as unhealthy.
A six-month study found that patients using GLP-1 and dual GLP-1/GIP receptor agonist therapy experienced minimal lean muscle mass loss as they lost weight. Regular resistance training, consistent protein intake, and close supervision by an expert obesity doctor were associated with better muscle retention.
A systematic review of nearly 6000 runners found that lower energy and fat intakes were strongly associated with a higher risk of injury in female runners. A low-fibre diet also increased the likelihood of bone stress injuries.
A new survey found that nearly 9 out of 10 US adults incorrectly assume they need to eat meat and dairy to get enough protein. Research supports the use of plant-based diets, with studies showing equal effectiveness in building muscle mass and containing fewer artery-clogging cholesterol and saturated fat.
Researchers found that CD44-deficient mice stayed lean despite a high-fat diet, while control mice developed obesity. The study suggests CD44 inhibitors could serve as a complementary treatment for obesity and related metabolic disorders.
A new Weizmann Institute study identified all proteins in a stool sample – those from the microbiome, human body, and food – revealing secrets of the intestines and their impact on human disease. The method, dubbed IPHOMED, decodes microbiome activity by showing which proteins come from bacterial strains and amounts.
Researchers suggest that understanding the science behind umami and koku could make plant-based eating more palatable. The authors reveal that key components of umami include free glutamate and nucleotides, while koku is related to small pieces of proteins called dipeptides and tripeptides.
A team of food scientists is developing tempeh products from chickpeas and peas to offset the health risks of a Western diet. The new fermented foods may help with obesity, fatty liver, hyperlipidemia, and diabetes. Preliminary research suggests they are high in fiber and low in fat.
A study of over 2,000 Korean older adults found that eating pork was positively correlated with nutrient intake, diet quality, and handgrip strength. The researchers suggest that pork can act as a carrier food to promote the consumption of other healthful components of the Korean diet.
Researchers from the University of Guelph studied plant-based proteins and their interaction with fat matrices to improve the quality of vegan cheeses. They found that a blend of pea protein, sunflower oil, and coconut oil created a cheese with a firm texture and lower saturated fat content.
A study from Tulane University found that a low-protein diet in one generation can lead to lower birthweights and smaller kidneys in offspring across multiple generations. The findings suggest that food scarcity or malnutrition may result in decades of adverse health outcomes.
A higher ratio of plant-based protein to animal-based protein may significantly lower the risk of cardiovascular disease and coronary heart disease. Consuming more plant protein overall, combined with a higher plant-to-animal protein ratio, provides the most heart health benefits.
