Abstract

Purpose

In Brazil, studies on dietary fiber consumption are scarce. The greatest difficulty is to obtain reliable data on the fiber content of foods that are part of Brazilians’ eating habits, which involves adjusting laboratory methodology. It is extremely important to evaluate the average daily fiber intake on a regional basis, considering the heterogeneous eating habits of the Brazilians. The study aims to estimate the average dietary fiber content of meals eaten in “by‐the‐kilo” restaurants.

Design/methodology/approach

The foods used in the preparation of 1,907 meals consumed during one month in four restaurants in the city of São Paulo were studied. Intake, nutritional composition, and fiber analyses focusing on average lunch intakes were performed based on the RDA and SBAN (Brazilian Food and Nutrition Society) recommendations. Intake and nutritional composition results were compared with the values of a control meal theoretically prepared. A total of 40 samples of preparations using fiber‐rich foods were analyzed and their dietary fibers and soluble and insoluble fiber fractions were determined by enzymatic‐gravimetric method.

Findings

The results showed that a lunch meal alone accounts for 69.2 per cent of the SBAN recommendation and 39.5 per cent of the maximum RDA for dietary fiber.

Originality/value

Foods served in “by‐the‐kilo” restaurants proved to be good sources of fiber, and their insoluble‐to‐soluble fiber ratios were similar to the recommendations.

Abstract

Purpose

Differences in dietary patterns constitute a major component of the environmental changes experienced by immigrant populations, and have been associated with several diseases with contrasting prevalence rates in the USA and Japan. The Japanese preparations present very colorful dishes, with a wide variety of vegetables with little or no cooking, which preserves the nutritive value of vitamins. The present study was carried out to determine the cholesterol/saturated fat index (CSI) levels of some Japanese dishes using the following equation, developed to calculate the ratio between cholesterol and dietary saturated fatty acids: CSI=(1.01 × saturated fatty acids in g)+(0.05 × cholesterol in mg).

Design/methodology/approach

Fifteen Japanese recipes consumed by Japanese immigrants in São Paulo (Brazil) were prepared and analyzed for chemical composition by AOAC methods, for fatty acids profile (gas chromatography) and cholesterol (colorimetric method).

Findings

Total lipid content (g/100g) ranged from 0.10 to 16.40, with mean±SD values of 2.83±4.10. Cholesterol (mg/100g) ranged from 0 to 166.5, with mean values of 36.90±45.61. CSI values ranged from 0.0 to 9.87, with mean values of 2.76±3.19.

Orginality/value

The habitual intake of Japanese foods available in São Paulo could be useful to achieve a limit of 30 per day for dietary CSI.
