Bioimpedance spectroscopy as a measure of physical functioning in nursing home residents.

Background And Aims: Intracellular resistance (Ri), a raw measure of bioimpedance spectroscopy (BIS), has been suggested for assessment of muscle health. The associations of repeated BIS measurements with functioning and nutritional status were investigated in nursing home residents suffering from poor health and disabilities.

Methods: A total of 106 nursing home residents (age 83±8 yrs, 75% women) were recruited.

Skeletal muscle gene expression profile is modified by dietary protein source and calcium during energy restriction.

Background/aims: The potential of whey protein and calcium to modify skeletal muscle gene expression during energy restriction (ER) was investigated in a model of diet-induced obesity.

Methods: Obese C57BL/6J mice received casein (calcium 0.4%) and two different high-calcium (1.

Effects of a fibre-enriched milk drink on insulin and glucose levels in healthy subjects.

Background: The glycaemic response to foods is dependent on the quality and content of carbohydrates. Carbohydrates in the form of dietary fibre have favourable effects on insulin and glucose metabolism and may help to control energy intake. Dairy products have a relatively low carbohydrate content, and most of the carbohydrate is in the form of lactose which causes gastrointestinal symptoms in part of the population.

Effects of high-calcium diets with different whey proteins on weight loss and weight regain in high-fat-fed C57BL/6J mice.

The aim of the study was to compare the effect of different whey protein-containing high-Ca diets on weight loss and weight regain in a model of diet-induced obesity. Obesity was induced in C57BL/6J mice with a high-fat (60 % of energy) diet. Weight loss by energy restriction was performed on four different high-Ca diets (1.

Metabolomic changes in fatty liver can be modified by dietary protein and calcium during energy restriction.

Aim: To characterise the effect of energy restriction (ER) on liver lipid and primary metabolite profile by using metabolomic approach. We also investigated whether the effect of energy restriction can be further enhanced by modification of dietary protein source and calcium.

Methods: Liver metabolomic profile of lean and obese C57Bl/6J mice (n = 10/group) were compared with two groups of weight-reduced mice.

Effect of dietary calcium and dairy proteins on the adipose tissue gene expression profile in diet-induced obesity.

Background/aims: Calcium and dairy proteins have been postulated to explain why the intake of dairy products correlates inversely with body mass index in several populations. We have shown that a high-calcium diet with whey protein attenuates weight gain and now we describe the effects of this diet on adipose tissue gene expression.

Methods: Nine-week-old C57Bl/6J mice were divided into two groups (n = 10/group).

High-calcium diet with whey protein attenuates body-weight gain in high-fat-fed C57Bl/6J mice.

An inverse relationship between Ca intake and BMI has been found in several studies. It has been suggested that Ca affects adipocyte metabolism via suppressing 1,25-dihydroxycholecalciferol (1,25(OH)2-D3) and decreases fat absorption. We studied the effect of Ca and milk proteins (whey and casein) on body weight in C57Bl/6J mice.
