People who know arehing cardiovascular health are great 'going to market and changing their diets – with the biggest difference over cooking oil, says anthropologist University Baylor
WACO, Texas (September 16, 2019) – A group of forest farmers in Bolivian tropical forests – who have significant cardiovascular health and have low blood pressure – have occurred in the body mass and body over a nine-year period, with increased use of the most significant nutrition change on cooking oil.
Tsimane, a pre-industrial society, traditionally said that they get fish, get farm, get farm and collect food for their lives, said Alan F. Schultz, anthropologist at Baylor University, Ph.D, MPH, co-author. studies published in the magazine Obesity. Their diet, traditionally higher in carbohydrates, fiber and protein and lower fat than average US diet, plantain, rice, manioc, maize and fruits as well as rough game, freshwater fish and occasional honey.
However, recent population growth, as well as narrowing of their territory, has put pressure on game and fish supplies, and more opportunities to attend school and earn pay correspond to reductions in traditional cultural knowledge and living practices. According to this study, people, such as pigs, refined sugar, cooking oil and domesticate foods, such as pigs, chickens and eggs, have more access to market foods, according to the study, carried out between 2002 and 2010, and t find them more.
“Objective measures suggest that this group is very healthy, with low average blood pressure and small heart disease. But there is only one part of his story, ”said Schultz. “It remains a response to how these characteristics fit with high rates of infectious disease, high mortality rates for children under 5 and moderately high levels of physical activity. Is their overall well-being too high? Or certain health measures only? Our findings on trend in weight gain and increased consumption of high calorie foods suggest that the benefits of change are not so obvious. ”
Researchers who conducted the 2017 NIH National Institute for Aging study reported that cardiovascular health at the Tsimane was better based on coronary artery calcium made with CT scans than ever in any other population and persistent low blood pressure. But they also reported less healthy lipid and glucose levels than previous research.
Using data from 365 men and 330 women over 20 years of age and living in the Amazonian lowlands, researchers received changes from 2002 to 2010, a timeframe that reflects increasing dietary access to market food. many cultivated crops. Researchers measured body mass index (BMI), percentage of body fat, waist circumference and fat-free mass.
As career and lifestyle changes are often associated with transfers from nutrition diets to market-based diets, it can be difficult to separate the effect of the diet compared to other health factors, Schultz said.
But “we saw that even small increases in market-based foods with enough calories even contributed to a small, fat, active, nutrient-based population,” he said. “There's so much flavor of cooking oil – we use it for a reason – but at 120 calories / 14 grams of fat per tablespoon, there is little food that could easily change your diet.” T
For Tsimane ’, access to market products is changing as well as economics. They are one of the 36 most remote indigenous groups, usually living in communities of 50 to 250 people. However, their population is growing rapidly – from around 6,000 people in the late 1990s to around 16,000 in 2015, according to a national census.
They still have limited access to running water, electricity and sanitation. But as migrants and rangers continue to move into the area, you are more likely to get income from contracts to remove forest products and work as day workers. This money is partly spent on processed foods and medical care.
Traveling to the nearest market town by foot or by dugout canoe can be between two hours and several days. “They can also buy from traders who travel the river through a motor boat, but recently many families have bought small, cheap motors to expedite trips to the market,” said Schultz. “Travel is changing a lot.” T
Tsimane's career remained almost entirely based on nutrition even years after the first road was built into its territory in the 1970s, beginning a rigorous period of logging for hardwoods by people outdoors and expanding missionary activities. As changes in environments and occupations change, Tsimane's health identified in many threatened academic studies appears to have many exceptional characteristics.
“Future research should focus on the final causes and consequences of recent changes,” said Schultz. “This includes, among other things, dietary experience, physical activity and infectious diseases as well as socio-economic determinants such as lifestyle expectations and social support.
“Does the market-based life condemn most of us to obesity, stress and heart disease? Will this affect Tsimane? If Tsimane careers are changing, we want to understand the final causes and effects of this change for their health – and for ourselves. ”
