Better Diet Data Via Tooth-Mounted Sensors

In First World countries, where famine is unheard of, people are instead eating themselves to death.

Surrounded by wealth and access to health care, non-communicable diseases are responsible for roughly 38 million deaths each year. Apart from sedentary lifestyles, smoking and alcohol abuse, our daily diets are also a primary driver of poor health. Food-related pathologies such as diabetes, cancer and heart disease are all ticking upward along with people’s standard of living.

So how do we get out of this funk? One way is for scientists to conduct large-scale studies to examine how people’s diets mesh with their lifestyles. Additionally, dieticians can also recommend individualized interventions based on a careful analysis of people’s daily food intake. But collecting these crucial data remain difficult; it’s not easy to get a highly accurate measure of the foods people eat.

Oftentimes, diet studies rely on self-reported surveys and journals that are hostage to the whims of each participant. People forget. People feel self-conscious about their food choices and may fudge (pun intended) the data. However, a new sensor that fits on a person’s tooth could cut out this unpredictable variable—human nature— altogether.

Researchers from Tufts University School of Engineering designed a tiny sensor that, when stuck to a tooth, can wirelessly relay precise information about glucose, alcohol and salt intake. When the device comes in contact with salt, for example, its electrical properties shift, causing its other components to absorb and transmit different radiofrequency wavelengths unique to each chemical or nutrient. That information is then beamed to a mobile device for recording.

“In theory we can modify the bioresponsive layer in these sensors to target other chemicals – we are really limited only by our creativity,” says Fiorenzo Omenetto, an author on the study, which was published recently in the journal Advanced Materials. If you can put it in your mouth, it appears Omenetto and his team can measure it.

It’s not to say that researchers haven’t leaned on technology to improve their dietary espionage, but the solutions are sort of clunky and still subject to inaccuracies. There are devices that measure the mechanical action of swallowing or biting, devices that capture sounds of munching and even devices that literally photograph the food people eat. At their heart, these solutions were meant to serve as a means to verify self-reported data from participants—not to stand on their own.

The solution from the Tufts team seems to solve many of these issues, and may leave researchers and dieticians smiling.

Yet Another Study Says Vitamin Supplements Are Worthless

(Credit: Thunderstock/Shutterstock)

Vitamin — the first four letters come from the Latin word for “life.” To sustain that, we need these organic compounds in small amounts, but it seems their purpose ends there.

New research reaffirms the counterintuitive notion that vitamin and mineral supplements aren’t the magical panacea we’ve been led to believe. It’s something that researchers have been finding for years, and a meta-analysis, summarizing the findings of 179 individual studies, published on Monday in the Journal of the American College of Cardiology found that most common vitamins provide precisely zero benefit to those taking them.

Non-vital Vitamins

Specifically, the study concluded that multivitamins, as well as calcium, and vitamins C and D are essentially powerless. They do no harm, but they might as well be placebos. These findings run contrary to popular wisdom, which instructs us to load up on supplements to reduce the risk of heart disease, cancer and premature death.

This isn’t the first time science has refuted vitamin worship. In 2013 a series of studies in the Annals of Internal Medicine, collectively including hundreds of thousands of participants, concurred that vitamins do not lead to any boost in health. In fact, the studies found that beta-carotene, vitamin E and possibly high doses of vitamin A actually slightly increase mortality.

The only supplement that may live up to its reputation, according to the new study, is folic acid. This, with or without vitamin B, may prevent cardiovascular disease and stroke.

The tradition of using vitamins and minerals for nutrient deficiencies dates back to 1747, when the British naval surgeon James Lind treated scurvy with citrus fruit, rich in vitamin C. Physicians routinely make such prescriptions, though usually only in cases where the patient has a demonstrated deficiency of a particular vitamin or nutrient.

Supplement Crazy

In recent years, though, we’ve come to view supplements as the gateway to general health and longevity. A Gallup poll in 2013 showed that 50 percent of Americans regularly take vitamins or multivitamins.

On the flip side, a comparison of Gallup polls in 1975 and 2016 reveals plunging public trust in the mainstream American medical system. This phenomenon may have contributed to the ascent of “natural” vitamin and mineral supplements.

But it probably also stems from rampant marketing and advertising. Thanks to the Dietary Supplement Health and Education Act of 1994, manufacturers don’t have to prove the to the Food and Drug Administration that their supplements work. They can claim their products work, though, as long as they keep it vague (“strengthens the body”) and don’t profess to truly treat anything.

Call it a healthcare failure, call it a marketing miracle. Either way, call a doctor before you pop another vitamin. Odds are they’ll tell you to stick to fruits and veggies.

Morgellons and Dope (Crack)

Even though this person in this video blog needs help with her drug addiction she shares her true story of being infected with morgellons. Everyone has their own way in dealing with this horrible disease. If you google Morgellons or resistant scabies mites you will come across forums of people questioning if some narcotic drugs could possibly get rid of these things. It’s not uncommon to hear individuals who gets high and complains about feeling bugs crawling all over them, biting them, etc. In reality in many cases it is true. Because of these narcotic drugs poisoning the system it drives them out of the body. Just as the same as if taking anti-parasitic drugs such as ivermectin.

Morgellons disease is a poorly understood condition characterized by small fibers, particles and bugs emerging from the skin. People with this condition often report feeling as if something is crawling on or stinging/ biting their skin.

In no way do we endorse or suggest in using any illegal substance to deal or attempt to get rid of morgellons or resistant scabies mites.
