Thirty-three Mexican Americans between the ages of 9 and 60 were interviewed and tested for lactose intolerance. The participants of the study included 16 children and 17 persons not related by ...birth, including the parents of the children. Determination of lactose intolerance was based on a rise of less than 25mg/100 ml of blood glucose as measured by an Ames Dextrostix/Reflectance Meter following consumption of a lactose load. Forty-seven percent of the 17 nonrelated Mexican Americans were lactose intolerant. There was a marked relationship between low rise in blood glucose and symptoms of diarrhea, flatulence, and distention. Sixteen children from four families had an incidence of 50 per cent intolerance. The findings of intolerance in two successive generations of three families and in both sexes of the families adds support to the contention that lactose intolerance has a genetic basis, without sex predilection.
An important debate exists on whether soybean expansion in Brazil is responsible for putting more pressure on the Amazon forest or if it allows land use intensification through the recuperation of ...degraded pasture. In this paper, we estimate regional soybean supply own and cross price elasticity in order to better assess the possible impacts of agricultural trade liberalization in old and new soybean production basins. Applying a panel data estimation technique, we find large substitution supply elasticity between soybean and beef in Brazil Moreover, own price elasticity of soybean supply is much higher in Cerrados regions that in the South of the country. These results allow to discuss possible regional consequences of soybean trade liberalization on the Amazon forest. The current movements to promote sustainable and responsible soybean production in Brazil could certainly modify the future response of the sector to trade liberalization and its long term impacts.
