Stevia is considered a "natural non-caloric sweetener." Saccharin and sucralose are considered "non-nutritive sweeteners" (few or no calories). Aspartame is a "nutritive sweetener" (adds some calories but far less than sugar).
Aspartame comes with a warning to be used cautiously (or not at all) by people with a rare genetic disease (called phenylketonuria, or PKU) because they have trouble metabolizing it; that's not true for the other sweeteners. And all four vary on their level of sweetness and aftertaste, which is likely why people often prefer one over another.

Stevia, a zero-calorie sugar substitute, is recognized as safe by the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). In vitro and in vivo studies showed that stevia has antiglycemic action and antioxidant effects in adipose tissue and the vascular wall, reduces blood pressure levels and hepatic steatosis, stabilizes the atherosclerotic plaque, and ameliorates liver and kidney damage. The metabolism of steviol glycosides is dependent upon gut microbiota, which breaks down glycosides into steviol that can be absorbed by the host. In this review, we elucidated the effects of stevia’s consumption on the host’s gut microbiota. #Stevia #kombucha #ikombucha_ro #ikombucha

Parkinson’s disease, renowned for its debilitating effects on movement, has always been intrinsically linked to the diminishment of dopamine, a chemical imperative for motor functions. However, a groundbreaking study by the University of Montreal divulges surprising revelations about the resilience of brain’s movement circuits even with a conspicuous deficiency in dopamine during the asymptomatic phases of Parkinson’s. This groundbreaking research, led by esteemed neuroscientist Louis-Éric Trude

Depression is not a gentle opponent, yet, forward-thinking studies and fresh advancements in technology have shed light on the way to triumph over this disease. In a new research study, there’s some positive news for the millions grappling with treatment-resistant depression (TRD). DBS (Deep Brain Stimulation) is beginning to show remarkable progress which seems to offer a ray of hope for the people who are suffering from debilitating Tourette’s syndrome. DBS, still an early stage trial, is a pr

Lung cancer is the leading cause of cancer-related deaths in the United States. Some tumors are extremely small and hide deep within lung tissue, making it difficult for surgeons to reach them. To address this challenge, UNC –Chapel Hill and Vanderbilt University researchers have been working on an extremely bendy but sturdy robot capable of traversing lung tissue.

Researchers publicly call out theory that they say is not well supported by science, but that gets undue attention.

A letter, signed by 124 scholars and posted online last week1, has caused an uproar in the consciousness research community. It claims that a prominent theory describing what makes someone or something conscious — called the integrated information theory (IIT) — should be labelled “pseudoscience”. Since its publication on 15 September in the preprint repository PsyArXiv, the letter has some researchers arguing over the label and others worried it will increase polarization in a field that has grappled with issues of credibility in the past.

For a phenomenon that is so deeply engrained in the public consciousness, the scientific evidence regarding what has been called "beer goggles" is surprisingly inconsistent. The term refers to finding people more attractive after drinking alcohol, and there is a wealth of scientific evidence both for and against its existence.

this is driving me pretty mad, i've got hygrometers, digital and analog all reading wildly different percentages, and would like to calibrate them, read up on the salt test, where you take salt make it damp stick it in a plastic bag and after +8 hrs the internal humidity of the bag should be exactly 75%. for anyone that's familiar with calibrating hygrometers, should 2 TBSP table salt plus 1/2 TBSP water in a small monkey dish, in a gallon bag work? or is it too much water for the salt, too big of a bag, too much or too little time. did the test overnight on 4 different hygrometers for 12 hours, took them out of the bag, and now after 30 minutes to equalize to room temp, are not only once again wildly off, but the lowest is reading what I would imagine to be 10 percentage points of how humid the room "feels". maddening. thanks.

RNA for the first time recovered from an extinct species A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.

There has been a real race among scientists to create a technology that enables easy protein sequencing. Professor of Chemical Biology Giovanni Maglia of the University of Groningen has now found the missing piece in the puzzle: a way to transport a protein through a nanopore, which allows sequencing of proteins in a simple, handheld device.

Autism—or the formal term, Autism Spectrum Disorder (ASD)—is a developmental difference presenting through symptoms on a spectrum concerning social interaction, communication and behavior. What’s really interesting about this disorder is that every single person with autism experiences it differently. They may have amazing special abilities in certain parts but may be lacking in other areas which makes it difficult to have a standard definition of autism. Visualize a rainbow of hues, each one di
