The Good News About Plant Foods. Over the past few of months there have been a slew of new studies reporting the benefits of plant-based foods.

The Good News About Plant Foods

From berries to broccoli, fruits and vegetables are increasingly being recognized for their health-promoting, disease-fighting, and anti-aging properties! Below is a roundup of the good news about plant foods…including 10 new studies from the first quarter of 2012 alone! Berries - Berries are without a doubt one of the most nutritious and delicious foods on the planet! Nearly all berries are high in vitamin C and fiber and low in calories, making them an excellent, nutrient-dense snack or add-in. Over the years, research has also found various types of berries to have anti-inflammatory, antioxidant and even cancer-fighting properties. For more information about the health benefits of specific berries, check out our recently-published piece: 6 Power-Packed Berries You Should Be Eating.

How stress influences disease: Study reveals inflammation as the culprit. Stress wreaks havoc on the mind and body.

How stress influences disease: Study reveals inflammation as the culprit

For example, psychological stress is associated with greater risk for depression, heart disease and infectious diseases. But, until now, it has not been clear exactly how stress influences disease and health. A research team led by Carnegie Mellon University's Sheldon Cohen has found that chronic psychological stress is associated with the body losing its ability to regulate the inflammatory response. Published in the Proceedings of the National Academy of Sciences, the research shows for the first time that the effects of psychological stress on the body's ability to regulate inflammation can promote the development and progression of disease. "Inflammation is partly regulated by the hormone cortisol and when cortisol is not allowed to serve this function, inflammation can get out of control," said Cohen, the Robert E.

The CD47-signal regulatory protein alpha (SIRPa) interaction is a therapeutic target for human solid tumors. Electricity from trees. Plants have long been known as the lungs of the earth, but a new finding has found they may also play a role in electrifying the atmosphere.

Electricity from trees

Scientists have long-suspected an association between trees and electricity but researchers from Queensland University of Technology (QUT), in Brisbane, Australia, think they may have finally discovered the link. Dr Rohan Jayaratne and Dr Xuan Ling from QUT's International Laboratory for Air Quality and Health (ILAQH), led by Professor Lidia Morawska, ran experiments in six locations around Brisbane, including the Brisbane Forest Park, Daisy Hill and Mt Coot-tha.

They found the positive and negative ion concentrations in the air were twice as high in heavily wooded areas than in open grassy areas, such as parks. Radon is a by-product of the radioactive decay of radium which is present in minute quantities in rocks and is continually exhaled by the ground. "We do not believe that ions are dangerous - the danger comes from the pollutants. Hayflick limit. The Hayflick limit[Note 1] (or Hayflick phenomenon) is the number of times a normal human cell population will divide until cell division stops.

Hayflick limit

Empirical evidence shows that the telomeres associated with each cell's DNA will get slightly shorter with each new cell division until they shorten to a critical length.[1][2] The concept of the Hayflick limit was advanced by Leonard Hayflick in 1961,[1] at the Wistar Institute in Philadelphia. Hayflick demonstrated that a population of normal human fetal cells in a cell culture will divide between 40 and 60 times. The population will then enter a senescence phase, which refutes the contention by Nobel laureate Alexis Carrel that normal cells are immortal. Each mitosis slightly shortens each of the telomeres on the DNA of the cells.

History[edit] Belief of cell immortality[edit] Prior to Hayflick's discovery, it was believed that vertebrate cells had an unlimited potential to replicate.

What's Really Making Us Fat? - Kristin Wartman - Health

New research reveals a far more complex equation for weight gain that places at least some of the blame on organic pollutants. Image: Laborant/Shutterstock Conventional wisdom says that weight gain or loss is based on the energy balance model of "calories in, calories out," which is often reduced to the simple refrain, "eat less, and exercise more. " But new research reveals a far more complex equation that appears to rest on several other important factors affecting weight gain. Researchers in a relatively new field are looking at the role of industrial chemicals and non-caloric aspects of foods -- called obesogens -- in weight gain. The CDC reports that "nearly all" Americans tested have BPA in their urine, "which indicates widespread exposure to BPA in the U.S. population.

" The participants in the AJCN study were given low, normal, and high amounts of protein and 1,000 more calories than needed. Robert H. Body clock link to heart disease. Scientists have raised the possibility that cardiovascular disease is linked to disturbances in the body's 24-hour clock.

Body clock link to heart disease

Working on mice, the Japanese team found a genetic risk factor for a form of high blood pressure is influenced by 24-hour or circadian rhythms. The study appears online in the journal Nature Medicine. Malfunctions in the body clock - which influences much of the body's chemistry - have been linked to many diseases. And lead researcher Professor Hitoshi Okamura said the latest study was in line with data which suggested shift workers, long-distance flight crews and people with sleep disorders have a heightened risk of heart problems.

High blood pressure - known as hypertension - can lead to heart attack, stroke, kidney damage, and many other medical problems. Many genes have been identified as being essential elements making up the circadian clock. For example, mice lacking a pair of molecules known as cryptochromes have an abnormal circadian rhythm. Strong correlation. Body clock 'alters' immune system. 17 February 2012Last updated at 01:43 By James Gallagher Health and science reporter, BBC News Will the time affect medicine?

Body clock 'alters' immune system

The time of the day could be an important factor in the risk of getting an infection, according to researchers in the US. They showed how a protein in the immune system was affected by changes in the chemistry of the body through the day. The findings, published in the journal Immunity, showed the time of an infection changed its severity. An expert said drugs were likely to take advantage of the body clock in the near future.

Plants, animals and even bacteria go through a daily 24-hour routine, known as a circadian rhythm. It has been known that there are variations in the immune system throughout the day. The immune system needs to detect an infection before it can begin to fight it off. In experiments on mice, the scientists showed that the amount of TLR9 produced and the way it functioned was controlled by the body clock and varied through the day. Time link. Heart Surgeon Speaks Out On What Really Causes Heart Disease. We physicians with all our training, knowledge and authority often acquire a rather large ego that tends to make it difficult to admit we are wrong.

Heart Surgeon Speaks Out On What Really Causes Heart Disease

So, here it is. I freely admit to being wrong. As a heart surgeon with 25 years experience, having performed over 5,000 open-heart surgeries, today is my day to right the wrong with medical and scientific fact. I trained for many years with other prominent physicians labelled "opinion makers. " Bombarded with scientific literature, continually attending education seminars, we opinion makers insisted heart disease resulted from the simple fact of elevated blood cholesterol.

The only accepted therapy was prescribing medications to lower cholesterol and a diet that severely restricted fat intake. It Is Not Working! These recommendations are no longer scientifically or morally defensible. Inflammation is not complicated -- it is quite simply your body's natural defence to a foreign invader such as a bacteria, toxin or virus.
