Blood pressure is a risk factor for a heart event and angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are common prescriptions.

Both types of medicines work on the renin-angiotensin-aldosterone system, a group of related hormones that act together to regulate blood pressure. ACE inhibitors lower blood pressure by blocking an enzyme early in the system so that less angiotensin, a chemical that narrows blood vessels, is produced, and blood vessels can remain wider and more relaxed. ARBs block receptors in the blood vessels that angiotensin attaches to, diminishing its vessel-constricting effect. 
A just completed clinical trial of K.Vita (Betashot), a dietary treatment for children and adults with severe forms of epilepsy, found it was well tolerated and reduced seizures.

The product was developed to offset the risks of the ketogenic diet, which mimics a fasting state by altering the metabolism to use body fat as the primary fuel source. Ketosis is when the body switches from carbohydrates to fat for body fuel.

It has shown some success with drug-resistant epilepsies but the restrictive high-fat, low-carbohydrate diet can cause constipation, low blood sugar, and stomach problems. 
During the COVID-19 pandemic, wealthier people had the money to stay home and order online. Not so for poor people, who instead made more trips to local dollar stores and small groceries to get their family's food.

Why is that bad? It isn't at face value, supporting local businesses is an aspirational claim for many, but a group of academics claim that without equal incomes and equal access to buying in bulk, poor people were worse off when it comes to making healthy food choices. That is like arguing muffin in a local bodega is bad while a muffin in a Whole Foods is good, when experts know the Whole Foods version has far more calories. 

An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences&Lettres University.

There is a belief that Airbnb listings cause increased crime in residential neighborhoods - or at least annoying late-night parties which increase risk of crimes. However, a new paper suggests that while Airbnb listings can be linked to a reduction in the local social dynamics that prevent crime, it isn't the tourists committing the crimes. And it takes years, which means Airbnb listings may be a symptom rather than the cause.
A new paper has statistically linked inflammatory bowel disease, an umbrella term for chronic inflammation of the digestive tract, to processed foods. But because every food is processed - no one eats wheat that hasn't been milled - the term has now become "ultra-processed."
