Zone diet

A 9-year-old boy with autism and overactivity was unresponsive to several drugs. Risperidone 0.5 mg bd was effective, reducing his Aberrant Behavior Checklist score from 103 to 57 by the end of the first week. Four weeks later his weight had risen from 34.6 to 37 kg. This rate of weight gain (0.6 kg/week) continued over the next 12 weeks. His weight was then contained by the use of the Zone diet, with an emphasis on slowly absorbed carbohydrates (examples include apples,... 

Researchers at Tufts University in Boston decided to put a number of diets to the test. They recruited 160 overweight or obese adults with an average BMI of 35 in a range of 27 to 42. Subjects were put on the Atkins low-carb diet, the Zone diet of combined...

Diet soft drinks contain appreciable quantities of aspartame, benzoic acid, and caffeine. What is the expected order of elution for these compounds in a capillary zone electrophoresis separation using a pH 9.4 buffer solution, given that aspartame has pJC values of 2.964 and 7.37, benzoic acid s pfQ is 4.2, and the pfQ for caffeine is less than 0.

Pesticides have a statistically reliable effect on children in zones where OCPs are intensively used (in the Salyansk region of Azerbaijan, the amount of OCPs introduced into humans exceeded public health standards by up to 7.7 times). Primary illness of the endocrine system increased 3.1 times in children up to age 15 (over a five year observation period) in disruptions in diet and metabolism, the nervous system, and the sensory and respiratory organs in increased frequency of illness (over five years) in children up to age 15 (an overall increase by 3.6 times, and by class of illness, from 2.2-7.6 times) in the prevalence of pathological disruptions according to data from medical examinations of children from 8-14 years (an overall increase by 2.3 times, and by class of illness by 2.0-8.4 times) in... 

For the inhabitants of the exclusion zone, situated in a forested region without well-developed economic and social infrastructures, it is of interest to estimate the relative contributions to internal exposure of forest food (berries and mushrooms) and conventional agricultural food (potatoes and milk). Some specialist studies have assumed that forest food represents only a small part of the diet of inhabitants of the exclusion zone, but we would suggest that in fact, it plays a major role. Typically, the consumption of forest food contributes 50% of the internal exposure dose, while for some critical population groups, it can exceed 80%. The definition of the spatial variation in pollution, the prevailing ecological conditions, and the diet should allow a scientifically-based prediction to be made of the internal exposure dose to the local population, and will help to identify the major risk factors within a certain time period following the Chernobyl catastrophe.

The hamster is susceptible to atherosclerosis. Nistor et al. (1987) fed male hamsters a hyperlipidemic diet consisting of standard chow supplemented with 3 % cholesterol and 15 % commercial butter for 12 months. Serum total cholesterol doubled after 3 weeks and attained a 17-fold value after 10 months. Up to 6 months, smooth muscle cells in the intima and media of the aorta as well as endothelial cells began to load with lipids. After 10 months the affected zones looked like human atherosclerotic plaque with huge cholesterol crystal deposits, calcium deposits and necrosis. 

These results indicate that intensive maize agriculture in southeast Missouri and northeast Arkansas began around 1000 AD, that the shift to maize was rapid, and 35 to 72% of the diet may have consisted of corn after this time. While several studies report the presence of maize kernels at midwestern archaeological sites as early as 500 BC (38). our data provide isotopic evidence that maize could not have been a significant part of the human diet prior to 1000 AD. Our 6 values of bone collagen before 1000 AD are identical to measurements made on prehistoric humans from northern temperate zones where no Ci, plants could have been consumed (19). Data from nearby archaeological sites in Illinois show a similar pattern of values tiirough time, with... 

Many lipids are essential to good human health. Some of them serve as chemical messengers in the body. Others serve as ways to store chemical energy. There is a good reason that babies are born with baby fat. Seeds contain lipids for the storage of energy. People living in Arctic zones seek fatty foods in their diet. 

The diet of marine iguanas primarily consists of nine different species of algae, all of which grow underwater and in the tidal zone of the islands. At times they will also ingest grasshoppers, crustaceans, and the afterbirth of sea lions.
