Data from 2067 participants (~76 yrs) without dementia were used to study blood glucose levels and dementia risk. During a median follow-up of 6.8 years, higher average glucose levels (in the past 5 yrs) were associated with an increased risk of dementia in both diabetics and non-diabetics, suggesting that higher glucose levels may be a risk factor for dementia, even in those without diabetes

This study examined eating habits and heart disease (CHD) risk in 26,902 men (45-82y) initially free of heart disease and cancer. Men who skipped breakfast had a 27% higher CHD risk and late night eaters had a 55% higher CHD risk. Other factors associated with skipping breakfast included smoking, drinking alcohol regularly, working full time, , and being less physically active.

This review assessed circulating and dietary magnesium and incidence of cardiovascular diseases (CVD). 16 studies including 313,041 individuals showed that circulating magnesium was associated with a lower risk of CVD. Dietary magnesium was associated with a 22% lower risk of ischaemic heart disease (IHD)which supports the need for clinical trials to evaluate the potential role of magnesium in the prevention of CVD and IHD

This 6-mo study compared weight loss diets with normal protein levels (NPD-0.8g PRO/kg body wt) vs high protein levels (HPD-1.2g PRO/kg body wt) in 72 overweight subjects. BMI and body fat mass decreased similarly in the NPD and HPD groups, but lean body mass, resting metabolic rate, and diastolic blood pressure changed favorably only in the HPD compared with the NPD group. A higher protein diet may be more effective for long term wt loss.

Energy-restricted high-protein diets (HPDs) have shown favorable results for body weight (BW) management, yet studies differ in their outcomes depending on the dietary protein content. Our objective was to determine the effects of dietary protein content on BW loss-related variables during a 6-mo en...

This 6-month study was a randomized, placebo-controlled, double-blind trial of 176 adults (ages 18–45 y) who consumed 1.16 g DHA/d or a placebo. Reaction times (RT) of episodic and working memory improved with DHA compared with placebo. This study showed that DHA supplementation improved memory and the RT of memory in healthy, young adults whose diets were low in DHA.

This study examined the effects of 6 days of high-protein (HP) and normal-protein (NP) 350 calorie breakfasts on appetite, satiety, and snacking in 20 overweight breakfast-skipping girls. Both breakfasts reduced hunger but the HP breakfast elicited greater responses and reduced evening snacking of high-fat foods. Breakfast, particularly one rich in protein, may be a useful strategy to improve satiety and improve diet quality in overweight teen girls.

This study evaluated baseline vitamin D levels [25(OH)D] and incidence of type 2 diabetes (T2D) for up to 5 yrs in 1080 nondiabetic high-risk Asian subjects. Incidence of T2D declined with increasing 25(OH)D levels; those with the lowest 25(OH)D levels (
