[Nutritional status, food consumption and food supply of studies in Saudi Aribia. I. Anthropometric data].

A field study about the nutritional status was made in school classes with boys 6 to 19 years old in different regions of Saudi-Arabia. It is reported about 341 pupils in regard to weight, height, skinfold-thickness, circumferences and other body-size measurements. In comparison with anthropometric measurements of comparable surveys in other countries, the Saudi-Arabian school boys were found to be smaller and leaner than boys from the USA, Europe, other Arabian countries and well-to-do Indian boys.

[Nutritional condition, food consumption and nutritional intake in students in Saudi Arabia. II. Food consumption and nutritional intake].

In field surveys in 13 schools in different regions of Saudi-Arabia, energy expenditure, food consumption, and nutrient intake were studied. Cereal products, especially bread, have the greatest significance in nutrition. Many students do not eat other foodstuffs regularly. A certain dependency of food consumption from the region was found in regard to the schools. The frequency of foodstuffs was generally low, but lowest in remote villages. In some age groups, the sufficient energy intake leaves much to be desired, 70 % do not reach recommended dietary allowances of animal protein and 100 % in fat. Intake of carbohydrates was too high, while intake of linoleic acid, minerals and vitamins is too low of nearly all test persons. To secure regularly a sufficient intake of essential nutrients, a school lunch program for the Saudi-Arabian boys is to be recommended.

[The sulfur dioxide in various population groups in the German Federal Republic].

In direct nutrition surveys, mostly with precise weighing methods, the SO2 intake was estimated in 10 groups of population in the FRG. The averages in the groups are in comparison with the FAO/WHO recommendation very low. This result was also found in most of the people in surveys. From group to group there is a wide range and in the groups too. The highest intake in sulfur dioxide has a group of winegrowers with 0.88 mg/kg body weight and day.

[Comparison of time, material and preparation costs as well as nutritive value of conventionally prepared soups and sauces and corresponding "convenience foods"].

In a survey the food and labour costs arising in connection with the preparation in feeding centers - with about a thousand dinners - of conventionally cooked soups and sauces and corresponding convenience food were determined. For soups food costs are lower for convenience food than for conventionally prepared soups. Regarding the sauces, the costs of one of the two preparation manners is not definetely more favourable than the other one. The cost scheme will shift to the disadvantage of convenience food whenever it has to be modified in default of a comparable product, as for instance in the case of béchamel-sauce and horse-radish sauce. Considering the factor time, convenience food will be unambiguously superior to conventionally cooked soups and sauces. The preparation of convenience soups takes only between one fifth and one eighth of the necessary time for the preparation of conventionally, of sauces only between one sixth and one twelfth of the required time. Soups and sauces made out of convenience food have a lower energy content than the conventionally cooked ones.
