Demographic, behavioural and dietary predictors of total fat intake in Montreal adults

Lifestyle and dietary predictors of total fat intake (%kcal) were examined, to identify groups potentially at risk of hypercholesterolemia. In 1987, 301 Montreal adults were sampled by random digit dialing. A diet history and lifestyle habits were recorded. Mean total fat intake (%kcal) was 34.75% ($pm$6.23). Principal Components Analysis identified specific dietary patterns. Regression analyses indicated that the first 4 food factors were associated with total fat intake (%kcal p $<$ 0.01). Household size was inversely related to total fat (%kcal); 0.8% less kcal from fat for each additional member of the household (p $<$ 0.01). Females had 2.8% more kcal from fat than males (p $<$ 0.01). The number of fast food meals consumed per week was positively associated with outcome when age was considered (p $<$ 0.05). BMI and education level were not associated with total fat (%kcal). Smoking was associated with intake of higher fat foods (p $<$ 0.01). These predictors can identify groups in the population who may be at increased cardiovascular risk

Bioequivalence of encapsulated and microencapsulated fish-oil supplementation

Omega-3 oil from fish can be stabilised against oxidation using a variety of microencapsulation technologies. Complex coacervation has been used and found to be commercially useful for fortifying foods and beverages with long-chain omega-3 containing oils. Here we report a comparative human bioavailability study of microencapsulated omega-3 fish oil and standard fish-oil soft-gel capsules. Phospholipid levels of long-chain omega-3 fatty acids increased equivalently in both subjects groups. Also, triacylglycerol levels were reduced similarly in both groups. These results indicate that omega-3 fatty acids have equivalent bioavailability when delivered as microencapsulated complex coacervates or as soft-gel capsules.<br /
