Link found
between pesticides and type-2 diabetes
Pesticides in food, air and water
may be directly linked with the development of type 2 diabetes, regardless of a
person's age, gender or body mass index, a new Spanish research study has found.
These substances tend to concentrate in body fat, and they might be one of the reasons why obese people are more likely to develop diabetes, since the greater the fat, the higher the pesticide concentrations in the body, researchers from the University of Granada found.
Researchers demonstrate that people with higher concentrations of DDE - the main metabolite in the pesticide DDT - are four times more likely to develop type 2 diabetes than other people, the journal Environmental Research reports.
In addition, the risk of type 2 diabetes is also associated with exposure to I-HCH (beta-Hexachlorocyclohexane), which is present in the formula of the pesticide Lindano, according to a Granada statement.
Researchers analyzed concentrations of a specific group of pesticides in the adipose tissue of 386 adult subjects at San Cecilio hospital, Granada, and Santa Ana hospital, Motril, Spain.
Granada researcher Juan Pedro Arrebola said: "Human adipose tissue (fat) acts as an energy reservoir and has an important metabolic function. However, adipose tissue can store potentially harmful substances, such as persistent organicpollutants (COPs-pesticides)."
COPs are a group of chemicals with diverse characteristics which are present in pesticides, industrial waste and building material. These compounds penetrate the body mainly through food, but also through air or the skin.
The prevalence of diabetes in the world has significantly increased in the last decades. It is estimated that by 2030, 4.4 per cent of the world population will live with this metabolic disorder.

Asian plants may offer remedy for diabetes
Two
plants from South East Asia may have anti-diabetic
properties and could help tackle obesity as well, believe British researchers.
A team of researchers at the University of Greenwich plans to investigate Cassia auriculata and Cassia alata whose extracts could yield active ingredients for a remedy to diabetes which exists in two forms - Type 1 and Type 2.
The former normally affects children, while type 2, which is most common in adults, (often diagnosed later in life) can be managed by diet, exercise and weight loss to some extent.
The group had previously hit upon a constituent called kaempferol 3-O-rutinosidehe from the extracts of one of the plants which was proven to be eight times more potent than the standard anti-diabetic drug acarbose.
The researchers have also identified anti-oxidant properties of the plants which aids in diabetes treatment.
"Our other most interesting finding is that many of the active ingredients from the Cassia auriculata plant work through a process called 'synergism' -- in other words, they work together to produce an effect greater than the sum of their individual effects," says Dr Solomon Habtemariam of the research team.
