“…In the present study we repeated a previous finding that meals containing egg white protein induce greater satiety than wheat gluten protein [14] and have further extended this finding to both male and female rats and for both 35% and 20% protein levels. We further showed that the increased satiety from egg white was accompanied by increased postprandial plasma amino acids and lowered respiratory exchange ratio (RER).…”

“…The criteria for the levels of protein used were the following: i) above the recommended amount of protein intake (12-18%) in both humans and rodent diets; ii) 20% protein reflecting the 90th percentile of protein intake within the population and the typical recommended level in high-protein diets in humans, whilst iii) the 35% was included to reflect the upper-limit of high-protein diets in humans [40]. In regards to the other macronutrients, in order to keep the diets isoenergetic changes in levels of protein needed to be paralleled by changes in carbohydrates, keeping the fat levels constant, as previously recommended [14].…”

“…Ratings of appetite and subsequent food intake also appear to differ following test meals containing soy, pea, tuna, turkey, and egg protein sources [7,[11][12][13]. Furthermore, we have previously observed that rats given 35% egg white protein as the first meal of the day were more satiated than when provided a 35% wheat gluten protein meal [14]. However, the underlying physiological mechanisms explaining the differential effects of the alternate sources of protein remain unknown.…”

High-protein diets are popular for weight management because of their ability to enhance satiety but not all protein sources are similarly anorexigenic. We recently reported that egg white protein is more satiating than wheat gluten in Sprague Dawley rats. The goal of this study was to identify physiological correlates of the satiety differences and to test long-term consequences on metabolism, body composition and body weight. At both 20% and 35% levels, egg white increased total plasma amino acids relative to wheat gluten. Insulin levels were unaffected but respiratory exchange ratio was reduced for several hours following 35% egg white relative to the other diets. No chronic effects on body weight, body composition, energy intake, or energy expenditure were observed. Results suggest that increased satietysignaling amino acids may underlie greater short-term satiety from egg white, but when consumed only once per day, produces no long term consequences for body composition.

“…Differences in food intake after the administration of an equivalent protein dose have previously been reported in the literature. In a study in rats, a high-protein meal composed of egg white suppressed food intake while a wheat-gluten-based meal containing the same percentage of protein, fat, and carbohydrates increased food intake [49]. Other examples are found in the literature for human studies.…”

Gastrointestinally Digested Protein from the Insect Alphitobius diaperinus Stimulates a Different Intestinal Secretome than Beef or Almond, Producing a Differential Response in Food Intake in Rats

In this study we compare the interaction of three protein sources—insect, beef, and almond—with the gastrointestinal tract. We measured the enterohormone secretion ex vivo in human and pig intestine treated with in vitro digestions of these foods. Insect and beef were the most effective in inducing the secretion of CCK, while almond was the most effective in inducing PYY in pig duodenum. In the human colon, almond was also the most effective in inducing PYY, and GLP-1 levels were increased by insect and beef. The three digested proteins reduced ghrelin secretion in pig duodenum, while only insect reduced ghrelin secretion in human colon. We also found that food intake in rats increased in groups fed a raw insect pre-load and decreased when fed raw almond. In conclusion, the insect Alphitobius diaperinus modulates duodenal and colonic enterohormone release and increases food intake in rats. These effects differ from beef and almond.

“…Furthermore, Du et al examined the influence of the protein level and source on Barnes maze performance, satiety and plasma amino acid levels in male rats. Results demonstrate the importance of protein source for cognition and satiety enhancing effects of a high-protein meal [37] (Table 1). Meta-analyses indicate that higher adherence to the Mediterranean diet is associated with better global cognition, episodic memory, lower risk of cognitive impairment and neurodegenerative diseases [38−40].…”

Macronutrients and water – do they matter in the context of cognitive performance in athletes?

Proper nutrition is a key factor in physical performance, but there are also indications of an impact of dietary components on the brain function. Therefore, the aim of the study was to assess the impact of macronutrients and water on cognitive performance. Assumptions of the Mediterranean diet correlate with better global cognition, episodic memory, lower risk of cognitive impairment and neurodegenerative diseases. In turn, a high-fat and high-sugar diet shows the opposite effect. Omega-3 fatty acids could be used as a preventive tool for cognitive decline, but there is still insufficient evidence if supplementation improves cognitive functions. The proper intake of protein may be important in cognitive performance. Tyrosine seems to be potentially effective in inhibition of fatigue under extreme conditions, and the influence of BCAA on cognitive performance is still unclear. An appropriate glucose level is a critical factor for brain functions. Carbohydrate supplementation before and during exercise is associated with enhanced brain activation and decreased exercise perception, as well as improved cognitive functions. Dehydration worsens cognitive performance, especially for tasks requiring attention, executive functions and coordination. Based on the review of available studies, it should be assumed that proper nutrition might play a relevant role in athletes’ cognitive performance.
