Relative measurement the main food menu in the painting in the period 1000-2000 resulted in data that make us stunned. However, this research also drawn criticism.
Obesity has long been a problem. Ancient peoples of China and the Ancient Egyptians have raised very disturbing health obesity. In fact, the Ancient Egyptians called it as a disease.
However, not a few who believe that obesity as a symbol of wealth and beauty. Famine stricken communities who often see overweight as a symbol of prosperity.
Nevertheless, the diverse views that change as medical science began to examine scientifically the impact of obesity. In 1940 - an, antiobesity campaign began after a study conducted on the impact of obesity on the heart. Obesity is the highest risk factors cause heart disease.
Year 1996, when it was discovered Body Mass Index (BMI), obesity issues more protruding. This index to determine whether a person is classified as overweight or not. Currently, cases of obesity are very high. In fact, had struck the children and adolescents.
Several years later, the United States to make maps and trends of obesity in several states. Every year there are more states that citizens are not free from the problem of obesity. Increasing risk levels.
Various methods are used to solve the problem of obesity in developed countries. Studies conducted to find the history, causes, and various possibilities to overcome them.
Out of the usual pathways of obesity research conducted in, Brian Wansink of Cornell University, and Craig S. Wansink from Virginia Wesleyan College examines changes by checking food portion sizes of food in the painting. The painting used is the Last Supper-themed paintings from the book published by Phaidon Press Last Supper in 2000.
The results, entitled The Largest Last Supper: depictions of portion Increased Size and Plate Size Over The real new Millennium will be published in the International Journal of Obesity this April. However, abstracts and summaries of this research have appeared in several sites.
The paintings are well-known paintings. The theme of the painting was taken from the Gospels when Jesus held a banquet on the last night before He was betrayed by his students to cross. The painting entitled "Last Supper" is a very famous painting by Leonardo da Vinci, who was still in the walls of Santa Maria delle Grazie Church in the City of Milan, Italy. Brian and Craig argue that has not analyzed the changes in the painting as time changes. One millennium witnessed a dramatic improvement and changes in the production, availability, and food security. They suspect this change is reflected in the painting during that period.
This research was done by rests on the notion that art is imitation of life. From this assumption, then measured a number of things related to food, such as the size of the plate, the size of bread, and also the size of the main food (fish and meat), which is in the 53 paintings of the Last Supper. In addition, the average measured volume of the head of the characters in the painting.
To make the size of the dishes, breads, and main meals as well as the head, investigators using CAD-CAM programs used for design. The painting measured is within the range of 1000 to 2000-a millennium.
To make proportional comparisons, the researchers made a comparison between the size of the index plate, bread, and a main meal with the size of the head in the painting. So, like painting one of the indexes is 2.0, the size of bread two times higher than the average size of the head.
The first calculation is to find the parameters that have the highest significance and correlation within a certain time. The changes of the size of bread, main food size, and size of the plate against the size of the head with a certain period, namely 1000-1300, 1300-1400, 1400-1500, 1500-1600, and 1600-2000 is known that the main food size parameters are correlated and high significance, i.e. 0.52 and 99 percent confidence level.
Relative size of the main food used to measure changes in the size of the food in a certain period. In this study, measurement of time is a hundred years from 1000 until 2000. By using nonlinear regression method, the results showed a tendency portion of the main foods continued to rise since the year 1000 until 2000 (see picture).
The main food portion sizes are increased by 69.2 percent in 1000-2000. This is the biggest change compared to changes in the size of bread (23.1 percent) and the size of the plate (65.6 percent). There is also soaring food size in the period 1500-2000.
This result is very surprising in the midst of efforts to various circles in developed countries tackle the problem of obesity. Very probably the result of research Brian and Craig is in line with the problem of obesity.
However, there is a view, there is no unique and something new from the study. "The results of this research is not much to give meaning to science," Martin said Brinks, behavioral health psychologist and a consultant at Duke University Medical Center, as quoted by a website.
He said that there are actually real examples of food portions increase. "You all can see the changes in the size of ready meals in restaurants," he said.
He suggested is better carried out to evaluate changes in today's foods that are large. "We can see how changes in society related to food," he said.
