ככה נראה רפרנס וסקירה, כי כבר דנו על כך בעבר
אני מבקש רפרנס ואתה כל הזמן שולח אותי לדברים הזויים. אז הינה דוגמה ל REVEIW בלי אג'ינדה: Nutr Rev. 2010 Oct;68(10):616-23. doi: 10.1111/j.1753-4887.2010.00321.x. Effect of protein intake on bone and muscle mass in the elderly. Genaro Pde S, Martini LA. Nutrition Department, School of Public Health, University of São Paulo, São Paulo, Brazil. Abstract The aging process is frequently characterized by an involuntary loss of muscle (sarcopenia) and bone (osteoporosis) mass. Both chronic diseases are associated with decreased metabolic rate, increased risk of falls/fracture, and, as a result, increased morbidity and loss of independence in the elderly. The quality and quantity of protein intake affects bone and muscle mass in several ways and there is evidence that increased essential amino acid or protein availability can enhance muscle protein synthesis and anabolism, as well as improve bone homeostasis in older subjects. A thorough evaluation of renal function is important, since renal function decreases with age. Finally, protein and calcium intake should be considered in the prevention or treatment of the chronic diseases osteoporosis and sarcopenia.

Crum AJ, Corbin WR, Brownell KD, Salovey P. Abstract Objective: To test whether physiological satiation as measured by the gut peptide ghrelin may vary depending on the mindset in which one approaches consumption of food. Methods: On 2 separate occasions, participants (n = 46) consumed a 380-calorie milkshake under the pretense that it was either a 620-calorie "indulgent" shake or a 140-calorie "sensible" shake. Ghrelin was measured via intravenous blood samples at 3 time points: baseline (20 min), anticipatory (60 min), and postconsumption (90 min). During the first interval (between 20 and 60 min) participants were asked to view and rate the (misleading) label of the shake. During the second interval (between 60 and 90 min) participants were asked to drink and rate the milkshake. Results: The mindset of indulgence produced a dramatically steeper decline in ghrelin after consuming the shake, whereas the mindset of sensibility produced a relatively flat ghrelin response. Participants' satiety was consistent with what they believed they were consuming rather than the actual nutritional value of what they consumed. Conclusions: The effect of food consumption on ghrelin may be psychologically mediated, and mindset meaningfully affects physiological responses to food. ההבדלים: בראשון לקחו מגוון רחב של מחקרים וסקרו אותם. בשני לקחו קבוצות, חקרו אותם והגיעו למסקנות. יש לך מחקר לתת לי לגבי לאוסטיאופורוזיס וצריכת חלב?
