BACKGROUND The health effects of conventional yogurt have been investigated for over a century ; however , few systematic review s have been conducted to assess the extent of the health benefits of yogurt .
OBJECTIVE The aim of this scoping review was to assess the volume of available evidence on the health effects of conventional yogurt .
Effects of a breakfast yoghurt, with additional total whey protein or caseinomacropeptide-depleted alpha-lactalbumin-enriched whey protein, on diet-induced thermogenesis and appetite suppression.
Previous studies have shown effects of high-protein diets , especially whey protein , on energy expenditure and satiety , yet a possible distinction between the effects of whey or alpha-lactalbumin has not been made . The present study assessed the effects of the addition of total whey protein ( whey ) or caseinomacropeptide-depleted alpha-lactalbumin-enriched whey protein ( alpha-lac ) to a breakfast yoghurt drink on energy expenditure and appetite suppression in human subjects . A total of eighteen females and seventeen males ( aged 20.9 ( sd 1.9 ) years ; BMI 23.0 ( sd 2.1 ) kg/m2 ) participated in an experiment with a r and omised , three-arm , cross-over design where diet-induced energy expenditure , respiratory quotient and satiety were measured . Breakfasts were isoenergetic and subject-specific : a normal-protein ( NP ) breakfast consisting of whole milk ( 15 , 47 and 38 % energy from protein , carbohydrate and fat , respectively ) , a high-protein ( HP ) breakfast with additional whey or a HP breakfast containing alpha-lac ( 41 , 47 and 12 % energy from protein , carbohydrate and fat , respectively ) . Resting energy expenditure did not differ between the three conditions . HP breakfasts ( area under the curve : whey , 217.1 ( se 10.0 ) kJ x 4 h ; alpha-lac , 234.3 ( se 11.6 ) kJ x 4 h ; P < 0.05 ) increased diet-induced thermogenesis more compared with a NP yoghurt at breakfast ( 179.7 ( se 10.9 ) kJ x 4 h ; P < 0.05 ) . Hunger and desire to eat were significantly more suppressed after alpha-lac ( hunger , - 6627 ( se 823 ) ; desire to eat , - 6750 ( se 805 ) mm visual analogue scale ( VAS ) x 4 h ; P < 0.05 ) than after the whey HP breakfast ( hunger , - 5448 ( se 913 ) ; desire to eat , - 5070 ( se 873 ) mm VAS x 4 h ; P < 0.05 ) . After the HP breakfasts , a positive protein balance occurred ( alpha-lac , 0.35 ( sd 0.18 ) MJ/4 h ; whey , 0.37 ( sd 0.20 ) MJ/4 h ; P < 0.001 ) ; after the NP breakfast a positive fat balance occurred ( 1.03 ( sd 0.29 ) MJ/4 h ; P < 0.001 ) . In conclusion , consumption of a breakfast yoghurt drink with added whey or alpha-lac increased energy expenditure , protein balance and decreased fat balance compared with a NP breakfast . The alpha-lac-enriched yoghurt drink  suppressed hunger and the desire to eat more than the whey-enriched yoghurt drink
