In this week's edition of Science Weekly, obesity research has the main role but there are other intriguing topics investigated by scientists too. Like how your gut is more protected after a foodborne disease, how eating alone affects heart health, or what you and your clients do with your nutrition to reduce your carbon footprint without going vegetarian or vegan.
How foodborne diseases protect the gut's nervous system
Prior infections appear to shield enteric neurons, preventing these key components of the body's 'second brain' from dying off when future pathogens strike.

The 5:2 diet: A good choice for gestational diabetes
Weight loss after gestational diabetes can prevent the onset of type 2 diabetes. Yet finding the most effective way to lose weight and keep it off can be a challenge, especially for mothers with a new baby. Now, new research suggests that the popular 5:2 or intermittent fasting diet is just as effective as a conventional energy-restricting diet, enabling women greater choice and flexibility when it comes to weight loss.

Brain reveals the risk for developing obesity
Obesity risk factors of family background are associated with changes in the brain function, finds a new study. The results show that the function of neural networks regulating satiety and appetite is altered already before a person develops obesity.

Why sugary drink taxes aren’t effective -- and how to change that
Study finds price tags need to mention the tax to sway consumers
Several U.S. cities have instituted taxes on drinks with added sugar in order to reduce consumption, but new research suggests these policies currently have one fatal flaw. The study found that sugary drink taxes only reduce purchasing if price tags at stores mention that consumers are paying that tax when they buy the drink.

Can eating alone be bad for your heart?
As women age, their risk of cardiovascular disease (CVD) exceeds men's largely because of decreased levels of estrogen that regulate vascular function. As a result, much research is focused on various risk factors. A new study suggests that eating alone may contribute to an increased risk of heart disease in older women.

Three ways to reduce the carbon footprint of food purchased by US households
Most consumers want to make food purchases that are smart for their wallets, their health and the environment. And while switching to a vegetarian or vegan diet can lower one's impact on greenhouse gas emissions, it may not be realistic or healthful for everyone. Now, researchers report three ways that Americans can reduce the carbon footprint of their food purchases, without requiring drastic dietary changes.

Save the planet (and your health) by steering clear of sweets and pastries
Need another reason to cut back on sugary foods and drinks, apart from an expanding waistline? They're not helping the environment, contributing to a higher cropland, water scarcity and ecological footprint, according to a new review.
