Some vegetables such as broccoli and peas, if incorporated in the daily diet, could possibly prevent obesity, a new study said. The research, published in the Cell Host & Microbe journal, said that a diet rich in dietary fibers could also prevent metabolic syndrome and promote the growth of good bacteria in the colon.
Other than the two veggies, the study also named blackberries, figs, coconuts, and raspberries because of its dietary fiber content, NDTV reported. Besides being loaded with essential vitamins and minerals, peas and broccoli can help in the proper functioning of the body.
Dietary fiber consumption
The researchers at Georgia State University said that when they enriched the diet of laboratory mice with fermentable fiber insulin, it prevented metabolic syndrome induced by a high-fat diet. They explained that metabolic syndrome is a cluster of conditions linked closely to obesity. It includes increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels.
If these conditions occur together, it increases a person’s risk of diabetes, stroke, and heart diseases. Metabolic syndrome and obesity are associated with changes in gut microbiota, the microorganism population which lives in the intestine, the Deccan Chronicle reported.
By manipulating dietary fiber content by adding fermentable fiber, it guards against metabolic syndrome, Dr. Andrew Gewirtz, a researcher, said. According to the study, the fermentable fiber inulin restored gut health and protected rodents against metabolic syndrome caused by a high-fat diet. It restored the gut microbiota levels, boosted the production of intestinal epithelial cells, and restored the expression of the protein interleukin-22 that prevented gut microbiota from invading the epithelial cells.
The team fed the mice for four weeks with a grain-based rodent chow, a high-fat diet and low fiber content with five percent cellulose as a source of fiber, or a high-fat diet supplemented with fermentable inulin fiber or insoluble cellulose fiber.
The results of the experiment indicated that insoluble cellulose fiber modestly reduced obesity and dysglycemia. The colon mass was restored when they returned the chow diet to the rodents.
Obesity as a contagious disease
While obesity has often been described as an epidemic, Science Alert said that the rising obesity figures might have more in common with infectious diseases. The website cited new studies that added evidence to the idea that being in a social network with a higher level of obesity places people more at risk of increasing the body mass index as if catching behaviors make people put on weight.
It cited a study made by American economists which found that families who live in military bases are exposed to communities with higher rates of obesity is linked with an increase in BMI in parents and their children.
Ashlesha Datar of the University of Southern California and Nancy Nicosia of the RAND Corporation used data from the Military Teenagers’ Environments, Exercise, and Nutrition Study. The research combined details on 1,111 young adolescents and over 1,300 parents assigned to one of the 12 military bases in the US.
Obesity incidents in the bases varied, from 21 percent in El Paso County in Colorado to 38 percent in Vernon County, Louisiana. When the BMIs of the teens and parents were measured, it was revealed that one-fourth of the teens and three-quarters of the parents are either overweight or obese.
The researchers adjusted for factors such as age, income, and rank. They found that military family members were more likely to have a higher BMI if they were assigned to a base with greater obesity levels. Among the explanations for the difference were exposure to local culture and the relationship was stronger for military families who lived off base in the surrounding community.
If a teen lived close to the base for more than two years, they also were more likely to have a higher BMI. But the authors said that while the research cannot definitively rule out the role of shared environments with the available measures, the findings suggest that other mechanisms may also be at work.
Overweight for life
Meanwhile, a new study by the Royal College of Pediatrics and Child Health found that four in five obese school children are likely to be dangerously overweight for life. It could cause them to lose 10 to 20 years of their life.
Professor Neena Modi, the president of the RCPCH, pointed out that investment in the health of children will make a huge difference to their health in later life and to their economic productivity. Modi said that the possibility of the obese kids remaining obese as adults is a very frightening statistic which the UK government must come to grips with.
Professor Russel Viner, the officer for health promotion of RCPCH, lamented that child health is not being given the political attention it deserves in Westminster. He considered policies such as the soft drinks industry levy and new tobacco control plan to be applauded, but the approach is piecemeal.
