A new study from Japan finds that in countries where people eat significant amounts of rice have lower levels of obesity.
For the study, the researchers examined data from 136 countries. They found that those countries where people ate on average at least 150 g of rice per day had significantly lower rates of obesity compared with countries where people ate less than the global average amount of rice which was around 14 g daily.
Lead researcher Prof. Tomoko Imai comments: “The observed associations suggest that the obesity rate is low in countries that eat rice as a staple food. Therefore, a Japanese food or an Asian-food-style diet based on rice may help prevent obesity.”
New research from the Washington State University finds that mice that performed physical exercises during pregnancy gave birth to offspring that were less likely to gain weight from high-fat diet later in life.
In the study, the scientists examined the offspring of mice that were engaged in moderate-intensity exercise for 60 minutes every morning during pregnancy. A group of offspring born from non-exercising mice was considered as a control group.
Lead researcher Jun Seok Son, a doctoral student, says: “Our data suggest that the lack of exercise in healthy women during pregnancy can predispose their children to obesity and associated metabolic diseases partially through impairing thermogenic function.”
For the study, the researchers fed mice a high-fat and high-sugar diet for 8 weeks. Half of the mice received the extract of camu camu every day. The results of the experiment showed that mice that consumed camu camu extract had 50% less weight compared to the mice who didn’t receive this extract.
Study co-author professor André Marette says: “All these changes were accompanied by a reshaping of the intestinal microbiota, including a blooming of Akkermansia muciniphila and a significant reduction in Lactobacillus bacteria.”
A new study, published in the Journal of Infectious Diseases, finds that people with obesity may carry the influenza A virus for longer periods of time compared to people with the normal weight. The study suggests that obesity affects the severity of flu symptoms, as well as the virus spreads.
For the study, a team of researchers collected and analyzed data on around 1783 people from Managua in Nicaragua during the three seasons of flu from 2015 till 2017. The results of the analysis showed that people with obesity who had flu shed the virus for 42% longer than people without the obesity.
Stacey Schultz-Cherry of the St. Jude Children’s Research Hospital in Memphis, US, comments on the public health implications of the study: “It is therefore even more important to develop effective strategies to prevent and control influenza, especially in the overweight and obese population,” she writes, “which could be challenging because of the poor vaccine responses in this population.”
A new study, conducted by the researchers from the University of Wisconsin-Madison, US, suggests that starting your meal with a serving of yogurt may reduce inflammation, protect from the harmful byproducts of gut bacteria.
To examine their suggestion, the researchers recruited 120 premenopausal women, half of them were obese, for the first experiment. Half of the participants had to eat 12 ounces of low-fat yogurt each day for 9 weeks while others ate non-diary pudding. The results showed that some inflammatory markers, such as TNF-alpha, were significantly reduced in those participants who ate yogurt.
Ruisong Pei, a postdoctoral researcher, says: “Eating 8 ounces of low-fat yogurt before a meal is a feasible strategy to improve post-meal metabolism and thus may help reduce the risk of cardiovascular disease and metabolic diseases.”
