Plant-based diets are often seen as healthier alternatives to eating meat and dairy - with around one in five adopting the diet for health reasons. The way of eating, which has risen in popularity by at least a third since 2017, can involve anything from ditching meat, to going fully vegan, without eggs, milk or cheese. However, these foods could be loaded with sodium, which could raise blood pressure, packed with obesity-causing saturated fat, and stripped of bone-building calcium, a major analysis suggests. Researchers evaluated more than 700 plant-based foods sold in supermarkets, including burgers, sausages, milk, cheese, and yogurt,...

Researchers from Ewha Womens University in Seoul, South Korea have managed to create a powerful chemical composition that can eradicate tumor cells, findings in the journal Angewandte Chemie reveal. The scientists created the promising new cancer-fighting drug by manipulating calcium levels in the cells — supposedly the the key to an “anti-tumor” formula. Typically, too many calcium ions are harmful and will suffocate elements of healthy cellular composition like mitochondria, known by every 9th-grade biology student as the cell’s powerhouse. But now, scientists have found a way to use that harmful over-influx to ward off and destroy tumor cells in...

About 800 million children have blood lead levels that affect their brain. Guilarte has been among the first to document what's happening at the cellular level of the brain that triggers a cascade of lifelong consequences—from learning difficulties and lower IQ scores to the risk of psychiatric diseases and drug abuse in adulthood. Can the damage lead has done to their children ever be undone? Decades of research has brought Guilarte and his collaborators closer to an answer. They've identified a certain flavonoid, a class of nutrients present in fruits and vegetables, that reverses some of the negative effects of...

There is an adverse association between calcium channel blocker (CCB) use and glaucoma, according to a study. Alan Kastner, M.D. and colleagues examined the association between systemic CCB use and glaucoma and related traits in a population-based cross-sectional study involving U.K. Biobank participants with complete data for analysis of glaucoma status, intraocular pressure (IOP), and optical coherence tomography-derived inner retinal layer thicknesses. Data were included for 427,480 adults (median age, 58 years), including 33,175 CCB users (7.8 percent). The researchers found that use of CCBs, but not other antihypertensive agents, was associated with increased odds of glaucoma after adjustment for...

A small (57 g) daily portion of Jarlsberg cheese may help to stave off bone thinning (osteopenia/osteoporosis) without boosting harmful low density cholesterol, suggest the results of a small comparative clinical trial. The effects seem to be specific to this type of cheese, the findings indicate. Jarlsberg is a mild and semi-soft, nutty-flavored cheese made from cow's milk. Previous research indicates that it may help boost levels of osteocalcin, a hormone that is associated with strong bones and teeth. Researchers studied women allocated to adding Jarlsberg (41) or Camembert cheese to their diet. Jarlsberg and Camembert have similar fat and...

Older women with more advanced abdominal aortic calcification (AAC) have a higher risk for late-life dementia, according to a study published online June 26 in The Lancet Regional Health: Western Pacific. Tenielle Porter, Ph.D., from Edith Cowan University in Joondalup, Australia, and colleagues analyzed data from 958 ambulant community-dwelling older women (aged 70 years and older) with lateral spine images captured at baseline from a bone density machine to assess AAC. The researchers found that during 14.5 years of follow-up, 15.7 percent of women had a late-life dementia hospitalization and/or death. Women with moderate and extensive AAC were more likely...

Kidney stones illustration. Mayo Clinic researchers found that enriching diets with foods high in calcium and potassium may prevent recurrent symptomatic kidney stones. Diets Higher in Calcium and Potassium May Help Prevent Recurrent Symptomatic Kidney Stones Not only can kidney stones cause excruciating pain, but they also are associated with chronic kidney disease, osteoporosis, and cardiovascular disease. If you’ve experienced a kidney stone once, you have a 30% chance of having another kidney stone within five years. Typically, doctors prescribe changes in diet to prevent recurrent symptomatic kidney stones. Unfortunately, there is little research available regarding dietary changes for those...

7 Reasons Not to Take Vitamin K with D If it isn’t clear from the title of my blog yet, I’ll make it clear. I don’t normally recommend combo supplements of vitamin D3 with vitamin K (either K1 or K2). I get asked all the time why my brand of D3 doesn’t have K in it, and it would have been cheap and easy to put it in there but I chose not to, because of SO many reasons which I’ll discuss today, but mainly because the combination can increase risk of kidney stones (within a few years) and may...

Fungus that draws gold from its surroundings has been discovered in Western Australia, stunning scientists who say it could signal new deposits. Found near Boddington, south of Perth, the strain of the Fusarium oxysporum fungus attaches gold to its strands by dissolving and precipitating particles from the environment. There may be a biological advantage in doing so, as the gold-coated fungus was found to grow larger and spread faster than those that don’t interact with the precious metal. “Fungi are well-known for playing an essential role in the degradation and recycling of organic material, such as leaves and bark, as...

Daniel Begay, who is Navajo, had always been told growing up that traditional American Indian foods were good for him. But because most American Indians are lactose intolerant, "they aren't getting that same source of calcium from dairy products," Begay says. Turns out that it's a traditional cooking method that is key to his bone health. The Navajo burn juniper branches, collect the ash and stir it into traditional dishes. The most popular: blue corn mush. Begay, a graduate student at Northern Arizona University, analyzed the amount of calcium in 27 samples of juniper from all over the reservation. But...

According to a new study published in the journal Scientific Reports, adding cinnamon to your diet can cool your stomach by up to two degrees. "The results of the study, which used pigs, seemed to show that cinnamon maintained the integrity of the stomach wall," said study co-lead author Prof. Kourosh Kalantar-zadeh, from RMIT University in Melbourne, Australia. "When pigs feed at room temperature, carbon dioxide gas increases in their stomach." "Cinnamon in their food reduces this gas by decreasing the secretion of gastric acid and pepsin from the stomach walls, which in turn cools the pigs' stomachs during digestion,"...

WEDNESDAY, Aug. 17, 2016 (HealthDay News) — Taking calcium supplements with the hope of keeping osteoporosis at bay may raise an older woman's risk of dementia, a new study suggests. And that seems particularly true if a woman has already sustained an event causing poor blood flow to the brain (cerebrovascular disease), such as from a stroke, researchers said. The study can't prove cause-and-effect. However, dementia risk was seven times higher in female stroke survivors who took calcium supplements, compared to women with a history of stroke who didn't use the supplements, the findings showed. The risk of dementia also...

In a quest to make concrete more durable and sustainable, an international team of geologists and engineers has found inspiration in the ancient Romans, whose massive concrete structures have withstood the elements for more than 2,000 years.Sample of ancient Roman maritime concrete from Pozzuoli Bay near Naples, Italy. Its diameter is 9 centimeters, and it is composed of mortar formulated from lime, volcanic ash and chunks of volcanic tuff. (Carol Hagen photo) Using the Advanced Light Source at Lawrence Berkeley National Laboratory (Berkeley Lab), a research team from the University of California, Berkeley, examined the fine-scale structure of Roman concrete....

In our planet's early history, 720 to 640 million years ago, thick sheets of ice covered the majority of the surface, as the Earth was locked in a deep freeze. But explosive underwater volcanoes changed the chemistry of the Earth's oceans and were key to breaking the planet from its icy state, according to a new study. Researchers at the University of Southampton believe underwater volcanoes helped to thaw out "Snowball Earth", and even led to runaway chemical chain reactions, which created the conditions for an explosion of life on Earth. While much of the driving forces behind glaciation during...

The atom-thick sheet of carbon, graphene already has a number of amazing properties to it, including strength and electrical conductivity. As impressive its conductivity is though, superconductivity is still greater and has been observed with graphene, but not explained. Researchers at the SLAC National Accelerator Laboratory and Stanford University have now found how graphene and calcium become a superconductor.Called calcium intercalated graphite, or CaC6 is produced by interweaving calcium and graphite, which is a means of isolating sheets of graphene. About ten years ago it was discovered that this material could become superconducting, but neither the exact means nor...

Like Earth, the interior of Mars has undergone a process known as differentiation. This is where a planet, due to its physical or chemical compositions, forms into layers, with denser materials concentrated at the center and less dense materials closer to the surface. In Mars’ case, this translates to a core that is between 1700 and 1850 km (1050 – 1150 mi) in radius and composed primarily of iron, nickel and sulfur. This core is surrounded by a silicate mantle that clearly experienced tectonic and volcanic activity in the past, but which now appears to be dormant. Besides silicon and...

Genetics will determine whether a person infected with Ebola dies, scientists claimed today. A new study has found DNA could be the key to tracking the deadly effects of the virus which has ravaged West Africa. The World Health Organisation revealed nearly 5,000 people have died from the disease, which has devastated Guinea, Liberia and Sierra Leone. A team of scientists at Washington University believe their study has identified genetic factors behind the mild-to-deadly range of reactions to the virus.

If each energy field pervading space is thought of as the surface of a pond, and waves and particles are the turbulence on that surface, then the new evidence strengthens the argument that a vibrant, hidden world lies beneath. For decades, the surface-level description of the subatomic world has been sufficient to make accurate calculations about most physical phenomena. But recently, a strange class of matter that defies description by known quantum mechanical methods has drawn physicists into the depths below... Of all the strange forms of matter, cuprates -- copper-containing metals that exhibit a property called high-temperature superconductivity...

"Pakistani fertilizer firm to expand in U.S., but balks on controlling bomb materials" SNIPPET: "The Pakistani corporation that has refused the Pentagon’s urgent appeals to control the flow of explosive materials to bomb-makers who kill U.S. troops is expanding its fertilizer manufacturing into the United States. And it is being done with the help of U.S. taxpayers through the municipal bond market."
