biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. the cultivation of genetically modified (gm) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. considering the fast pace of new advances in production of genetically modified crops,...

Poor dietary intake is one of the causes of obesity. Children nowadays consume more energy-dense foods, foods away from home, commercially prepared or processed foods, but less fruits and vegetables, and often skip breakfast.1,2 To correct dietary imbalances, dietary assessment is needed to design effective interventions. However, common dietary assessment methods, such as food records and 24-h...

OBJECTIVE To compare the fast food outlets and exercise resources across 3 communities with varying percentages of Native Hawaiians (NH) and to correlate these findings with obesity prevalence. METHODS Data on all food and exercise resources were collected from January through July 2006 within a 1-mile radius in 3 distinct communities (site A = higher % NH to site C = lower % NH). Comparisons...

OBJECTIVES 1) Explore the availability and accessibility of fast food energy and nutrient information post-NSW menu labelling legislation in states with and without menu labelling legislation. 2) Determine whether availability and accessibility differed compared with pre-menu labelling legislation in NSW. METHODS We visited 210 outlets of the five largest fast food chains in five Australian s...

Fractal analysis of the morphology of ice crystal particles in frozen food was attempted for frozen soybean curd (tofu). From a microscopic image analysis of the ice crystal particles, it was found that the perimeter of the ice crystal particles could be recognized as a fractal. Effects of the storage time and storage temperature on the fractal dimension (d(p)) of the perimeter of the ice cryst...

The 3M Petrifilm Staph Express Count plate method was compared with AOAC Official Method 975.55 for the enumeration of Staphylococcus aureus in selected foods. Four foods--cooked, diced chicken; cured ham; smoked salmon; and pepperoni--were analyzed for S. aureus by 12 collaborating laboratories. For each food tested, the collaborators received 8 blind test samples consisting of a control sampl...

A number of tests are available to identify food sensitivities. This article presents an analysis of the diagnostic value of nine different food sensitivity tests run concurrently on a healthy 33-year-old female with a previous diagnosis of environmental allergies. This case study evaluated conventional allergy tests (skin prick and serum IgE), tests of other immune-mediated reactions (serum Ig...

functional foods have a large and growing global market and are regarded as one of the most actively researched areas of food science. the growth in popularity of functional foods is attributed to the phenomena of consumer health care, increasing health awareness and knowledge in the many benefits of functional foods. common benefits of functional foods include reduction of disease, health main...
