Riboflavin status was assessed in 42 secondary school students before and after supplementing the food intake with 5 mg riboflavin daily for 7 days. Energy, protein, and riboflavin intakes were determined on foods actually consumed by each student. Riboflavin nutriture was based on urinary riboflavin excretion and erythrocyte glutathione reductase ...

The amounts of some 40 fatty acids in British foods, derived from food tables and from a major new analytical survey, have been applied to National Food Survey results to give the average intake of each fatty acid in 1981. The major sources of the more significant fatty acids are ...

The effect of giving a food supplement for 12 weeks to 12 elderly, clinically stable, patients was investigated longitudinally. During the period of supplementation, the mean grip strength, whole blood and plasma ascorbic acid concentration, serum and red cell folic acid and plasma vitamin D concentrations increased, and decreased when ...

1. Folate was measured microbiologically with Lactobacillus casei in extracts from a range of different foods at two incubation pH values, 6.1 and 6.8. 2. The values for folate content obtained at pH 6.2 were, in several instances, considerably higher than at pH 6.8. The 'positive drift' seen in the ...

1. The effectiveness of dietary ascorbic acid and procaine penicillin in ameliorating the response to the stressors glucagon, corticotrophin, withdrawal of food and water and extremes of environmental temperature, both short and long-term, has been assessed. 2. No consistent changes in the responses were found, but it is suggested that ...

Corn, made into tortillas (flat cakes baked from lime-treated corn) is the staple food of Mexico. The amino acid deficiencies of tortillas (TT) and boiled corn (BC), and the supplementary value of amaranth seed (PA), another traditional Mexican food, roasted to the point of "popping", were studied. The feeding tests ...

Data on food supplement usage were collected from 2451 adults in seven Western states. No significant differences were determined among states. A majority (66.6%) of the sample used some form of food supplements, with 40.0% consuming one to three supplements per day. The archetype food supplement user was likely to ...

Riboflavin status in 270 free-living and healthy elderly was determined from dietary intake (3-day food records) and erythrocyte glutathione reductase activity coefficients (EGR-AC). High EGR-ACs (greater than 1.35) indicate poor riboflavin nutriture. Mean dietary intakes of riboflavin were 1.86 +/- 0.64 (SD) for males and 1.58 +/- 0.69 mg/day for ...

In previous studies of the folate content of human milk, samples were prepared for assay by a method that resulted in a turbid solution that was then assayed by a turbidimetric microbiological method. We have used an improved microbiological assay in which the milks were treated with rennin to precipitate ...

A variety of food supplements were taken by 66 percent of the elderly persons in this study. Ascorbic acid and vitamin E were the most popular choices. Some supplements may have improved nutritional status, while others were probably inappropriate or unnecessary. The findings indicate that the elderly have a number ...

Microbiological assay with Lactobacillus casei was made to determine total folacin content of foods allowed in the Special Supplemental Food Program (WIC) serving low-income pregnant women in the United States, who are at risk for folacin deficiency. Results of the assay showed that, when foods with a high nutrient density ...

Gallic acid (3,4,5,trihydroxybenzoic acid) is a naturally occurring polyphenol comprising the major hydrolytic product of tannic acid. Gallic acid and tannic acid were previously shown to suppress food intake of animals to a similar extent. However, the mechanism by which this effect takes place has not been previously reported. Reported ...

This paper considers the needs of field level nutrition educators in developing countries for an easy method of giving usable dietary advice suited to specific family compositions, incomes, production patterns, seasons, and food preferences. It describes the development and application of a tool which combines available data on seasonal food ...

Folate-depleted, cryoprotected preparations of Lactobacillus casei are stable for at least eight months at -18 degrees C, capable of reproducible growth and suitable as a ready source of inoculum for measurement of folates in physiological fluids. Cryoprotected microorganisms can be a commercially available laboratory reagent, thus simplifying and further standardizing ...

Four high-protein food mixtures for feeding the young were formulated from locally available and relatively cheap legumes and cereals. Protein content of these mixtures ranged from 17.2 to 20.3 g%. Amino acid composition showed agreement with the FAO provisional pattern except for sulphur amino acids. Analysis of the mineral content ...

Various arginine HCl supplements (0.5-3%), half added to a basal commercial rodent chow (1.8% arginine) and half to the drinking water, were given to 8- to 9-week-old male CBA/J mice for 6 days. Control animals were fed the basal chow and drank tap water. All mice ate and drank ad ...

New Zealand white rabbits were thyroidectomized, then examined for hypothyroidism after 6 to 8 weeks. Serum thyroxine levels were reduced 77% after surgery. This occurred without apparent calcium homeostatic imbalances even though no calcium supplementation was added to the food or water. The advantages of using the animal and procedure ...

This bibliography is the seventh supplement to the original title which covered 1934-1969. The supplements include all titles of earlier years which were found after the original bibliography was published, Journal of Gerontology, 1971, 26, 391-422. Included in this year's supplement are 15 titles identified in a search of the ...

Eight Drosophila melanogaster strains, seven homozygous for AdhF alleles and one for an Adh-null mutant, were compared for ADH activity in males and adult mortality on ethanol-supplemented food. The strains differed considerably in these qualities. A positive correlation was found between ADH activity and LD50. The relevance of this finding ...

Absorption of folates, vitamin B6, pantothenate, and riboflavin from a natural food source (yeast) and from synthetic folylmonoglutamate was studied in 24 elderly subjects (age range, 73 to 101 years) and in 12 healthy younger subjects (age range, 24 to 42 years). All subjects absorbed riboflavin, vitamin B6, and pantothenate ...

Long term use of the drug diphenylhydantoin (DPH) has been associated with biochemical evidence of folic acid deficiency and rarely with megaloblastic anemia. The mechanism of this nutritional deficiency is uncertain but is thought to result from DPH-induced alteration in the intestinal absorption of conjugated and/or free dietary folate. The ...

Representative values for folacin in 299 foods have been developed, based on an extensive literature review. A provisional table of these folacin values has been prepared for foods in 100-gm. portions and for specified weights, representing common household units. The data reflect newer methodology than that used for a prior ...

1. Graded responses, in terms of both weight gain and food/gain ratios, were obtained to increasing increments of Na2SO4 added to diets containing suboptimal amounts of sulphur amino acids. 2. In most cases the relative efficiency of Na2SO4 ranged from 25% to 55% of that of synthetic methionine, when the ...

Availability of folic acid from seven commonly used Indian foods and from yeast was studied in normal human subjects. The method consisted of measuring urinary excretion of folate after the ingestion of a known amount of food folate. The mean availiability of folic acid from different foods was more than ...

Ingestion by healthy humans of small amounts of polyglutamate folates from yeast, equivalent to 300 mug of monoglutamate folate and containing 30 mug of "free folate," resulted in an appreciable elevation of the serum folate corresponding to 300 mug of synthetic pteroylmonoglutamate (PGA). Ingestion of higher amounts of polyglutamate folate ...

A convenient method for the estimation of food folates using human plasma as a source of folic acid conjugase has been standardized. Bovine, goat and dog plasma could not be used for the purpose because of low enzyme activity and slow reaction rates. Human plasma conjugase released food folates from ...
