The maximum mean discrepancy (MMD) is a recently proposed test statistic for the two-sample test. Its quadratic time complexity, however, greatly hampers its availability to large-scale applications. To accelerate the MMD calculation, in this study we propose an efficient method called FastMMD. The core idea of FastMMD is to equivalently transform the MMD with shift-invariant kernels into the amplitude expectation of a linear combination of sinusoid components based on Bochner's theorem and Fourier transform (Rahimi & Recht, 2007)...

The paper presents a comparative evaluation of antioxidant capacity and energy values of different foods groups in order to identify the most efficient combinations for correction of metabolic disorders associated with an imbalance in antioxidant system. In study integral method for determining of antioxidant and energy indicators (patent No 2,455,703) has been used. It has been revealed that the highest antioxidant-energy capacity (AE) of fresh juices has a pomegranate juice (AE = 3895.9 +/- 241.4 mg/L x kJ(-1)), other fresh juices inferior to him on this indicator: grenade>orange>lemon=apple> pomelo > mandarin > persimmon > kiwi > pears > avocado...

BACKGROUND: Food environment studies have focused on ethnic and income disparities in food access. Few studies have investigated distance travelled for food and did not aim to inform the geographic scales at which to study the relationship between food environments and obesity. Further, studies have not considered neighborhood design as a predictor of food purchasing behavior. METHODS: Atlanta residents (N = 4800) who completed a travel diary and reported purchasing or consuming food at one of five food locations were included in the analyses...

The quality and quantity of food intake affect body weight, but little is known about the genetics of such human dietary intake patterns in relation to the genetics of BMI. We aimed to estimate the heritability of dietary intake patterns and genetic correlation with BMI in participants of the Erasmus Rucphen Family study. The study included 1,690 individuals (42 % men; age range, 19-92), of whom 41.4 % were overweight and 15.9 % were obese. Self-report questionnaires were used to assess the number of days (0-7) on which participants consumed vegetables, fruit, fruit juice, fish, unhealthy snacks, fastfood, and soft drinks...

A consumer survey was conducted in a university fastfood mall to determine the food consumption and buying patterns of Philippine university students. The survey established that a typical fastfood consumer in the test university foodmall is female between 16 and 22 years old, with a purchasing capability of < or = US$1.79 for a complete meal, and who generally frequents the mall only once a day during weekdays. Wholesomeness, affordability and variety of the foods were the general basis for satisfaction of the typical student consumer...

Studies concerning French adolescents' eating habits have been published during the past four years. The review of such studies shows that nutrient intakes and food consumption are close to those of the adult population. Only the amount of nutrients especially with respect to lipids seems to be more satisfactory than in adults. This observation emphasizes the importance of familial environmental as the main factor of eating habits. French adolescents eat as the preceding generation even if some behaviors (snacks, fastfood) may appear very different from those in adults...
