Should everyone be taking vitamin D? – BBC Future

April 18, 2020

There are two main types of D. The first is vitamin D3, which is found in animals including fish and is the kind the skin makes when exposed to sunlight. The second is vitamin D2, which comes from plant-based foods including mushrooms. Studies have found that D3 is more effective, and the conclusions of a 2012 meta-analysis argue that D3 is the preferred choice for supplementation.

When his team analysed raw data from 25 clinical trials involving 11,000 patients from 14 countries, they found a small benefit to taking daily or weekly vitamin D supplements to reduce the risk of respiratory infections, asthma attacks and bronchitis. Although the paper soon attracted robust criticism, Martineau points out that the reduction of risk, while slight, is still significant and comparable to the effects of other health measures: to prevent a single respiratory infection, you’d have to give 33 people vitamin D supplements – compared to, for example, giving a flu vaccination to 40 people to prevent a single case of flu.

How to tell if Yogurt is bad, rotten or spoiled?

Although not a perfect test, your senses are usually the most reliable instruments to tell if your yogurt has gone bad. A small amount of liquid is ok in most yogurts, it is called whey and actually contains several nutrients that should be mixed into the yogurt before eating. But an increased amount of surface liquid (or, in the case of Yoplait yogurt and a few others that do not have any excess liquid to begin with, it’s when a puddle begins to form) and a curdling texture near the bottom of the container are the first signs of yogurt going bad. The final signal that your yogurt has indeed gone bad is the formation of mold and at that point you must throw the entire container away, no matter what. Live bacterial cultures in yogurt act as a preservative, but once those cultures start to die off then mold can start to form. Never consume mold in any shape or form!”

How to extinguish the inflammation epidemic | New Scientist

How to extinguish the inflammation epidemic QT: “Persistent background
#inflammation…dubbed…’para-inflammation’…is an unfortunate consequence of…long…lives. Stress is a…problem…Inflammation is being discussed…[as linking it]…w/ disease”

This persistent background inflammation might not always make us feel ill, but it can store up problems for the future, from heart disease to type 2 diabetes and neurodegenerative disease. In 2008,
immunobiologist Ruslan Medzhitov of Yale University dubbed this “para-inflammation” and argued that it is an unfortunate consequence of our longer, calorie-rich lives.

Stress is a particular problem. The hormone noradrenaline, which is released in anticipation of an impending life-or-death situation, sets off the same chain of events as an infection or injury. Yet although stresses passed quickly in our evolutionary past, these days many of us are walking around with a ticking time bomb of stress-induced inflammation that never quite goes away. “Chronic, low-grade inflammation is being discussed in our field as one of the main pathways linking stressful life conditions with disease,” says Nicolas Rohleder of Brandeis University in Massachusetts. Over the past few years, for example, Rohleder has found that the long-term strains of caring for a seriously ill family member, and a series of short-term stresses, both increase levels of inflammatory markers in otherwise healthy people.

One clue came in 2000 when Serhan and his team revealed that inflammation has an off switch. Until then, the reaction was thought to peter out as the immune cells that secrete cytokines gradually reduced in number and their effects became diluted. In fact, Serhan found that neutrophils and macrophages, the types of white blood cell that kick off the process, actively change tack once it has got going, releasing a second set of chemicals – called resolvins – that help mop up any remaining cytokines and sweep away any debris.
