High and low exercise intensity found to influence brain function differently

high low exercise mri

After low-intensity exercise, Rs-MRI showed that networks in the brain associated with cognitive control/attention were stimulated, while after high-intensity exercise, networks associated with emotions were more active, and those related to fatigue/motor function, decreased.
A new study shows for the first time that low and high exercise intensities differentially influence brain function. Using resting state functional magnetic resonance imaging (Rs-fMRI), a noninvasive technique that allows for studies on brain connectivity, researchers discovered that low-intensity exercise triggers brain networks involved in cognition control and attention processing, while high-intensity exercise primarily activates networks involved in affective/emotion processing. The results appear in a special issue of Brain Plasticity devoted to Exercise and Cognition.

"We believe that functional neuroimaging will have a major impact for unraveling body-brain interactions," said lead investigators Angelika Schmitt, MSc, and Henning Boecker, MD, Functional Neuroimaging Group, Department of Radiology, University Hospital Bonn, Bonn, Germany. "These novel methods allow us to 'look' directly into the brains of a group of athletes, and, maybe even more importantly, understand the dynamic changes in brain structure and function associated with the transition from a sedentary to a healthy lifestyle."

From vaccinations to viruses: Vitamin C is a potent antidote

vitamina C
The ability of properly-dosed vitamin C before and after a vaccination to block any potential short- and long-term toxic side effects while enhancing the antibody-forming aim of the injection was covered in an earlier OMNS article. [1] The points made in that article, along with their validation in the scientific literature, remain pertinent 8 years later. As emphasized in that article, the purpose of this article is not to praise or condemn the administration of vaccinations. Most who know me know my stance on this issue, coming from what I consider to be a purely scientific perspective. But that is not the purpose of this article.

Even the most ardent of vaccine supporters should be able to admit that vaccinations, however infrequently, sometimes result in an undesired outcome on the health status of the recipient. The "argument" then shifts as to whether the chance of such an outcome is so rare as to be reasonably and permissibly ignored. The pro-vaccine community maintains that population-wide vaccinations confer a high degree of protection against even more morbidity and mortality that would otherwise be inflicted by the diseases or conditions for which the vaccines are being given. However, here I emphasize the need for mitigation of the side effects of vaccination.

To fully appreciate the toxic origins of all disease, it is very important to understand the critical roles played by vitamin C and other major antioxidants in counteracting and minimizing the impact of new toxin exposures and old toxin damage. All toxins, whether originating from an infection, food or water intake, or environmental source, or even as an unintended consequence of a vaccination, inflict their damage on the body by directly or indirectly causing the oxidation of critical biomolecules in the body. When biomolecules are oxidized (depleted of electrons), they lose some or all of their natural chemical roles throughout the body and inside the cells. Essentially, oxidation inactivates the natural physiological role of a biomolecule.

In her Social and Cultural Neuroscience Lab at the University of Miami, assistant professor of Psychology Elizabeth Losin investigates the mechanisms underlying racial and ethnic disparities related to pain and pain treatment. She looks at the role the brain plays using functional MRI (fMRI) and the impact of social and cultural factors, including the doctor-patient relationship and stressful life experiences such as discrimination.

In the study "Neural and sociocultural mediators of ethnic differences in pain," published today in the journal Nature Human Behaviour, Losin, Tor Wager, Diana L. Taylor Distinguished Professor in Neuroscience at Dartmouth College, and colleagues identify possible brain and social factors underlying racial and ethnic disparities in pain. The researchers found that African American participants reported greater pain in response to a controlled pain stimulation than Hispanic or non-Hispanic white participants did. African Americans also exhibited differences in their brain responses to pain, which correlated with their personal histories of experiencing discrimination.

Comment: On a related note, a study on the effects of air pollution found that "The level of distress among black men, for instance, in areas of high pollution, is 34 percent greater than that of white men, and 55 percent greater than that of Latino men."

Quinton Plasma Water can play an important role in fertility and pregnancy

Making sure you are not deficient in the minerals and trace elements our body needs to function optimally is an important consideration if you are trying for a baby. Even with a healthy diet, the foods we eat are largely deficient in the minerals and trace elements that our cells need to function properly. Government figures have indicated that trace elements can be as little as one third of the levels they were just 40 years ago - yet our bodies need them for optimal function.

Although these minerals and trace elements are virtually impossible to source through land-raised food, such as meat or vegetables, the fertile areas of the seas and oceans still contain all the minerals and trace elements that our cells need to be healthy. The action of phytoplankton and zooplankton makes these elements bioavailable to us so our cells, including those involved in reproduction, can use them. This mineral-rich and bioavailable sea water is harvested and cold micro-filtered to pharmaceutical grade for you as Quinton marine plasma.

Quinton is mineral-rich seawater harvested under strict conditions from a plankton bloom, which naturally occurs in a pristine, internationally protected part of the Bay of Biscay in the Atlantic Ocean. This life-supporting seawater contains 78 minerals and trace elements minerals all present in the perfect proportions that the human body needs to be healthy.

Objective:Health #43 - Diet Dogma - When What We Eat Becomes Our Identity

O:H header
Diet dogma. Everyone wants to avoid it and generally we all think that we are. But it seems no dietary regimen comes without adherents that get a little too fundamentalist and authoritarian. While it's so common as to become a trope within the vegan community, Keto, Paleo and Carnivore diet communities seem to have their fair share of fundies, too.

Apparently no one is entirely free of this tendency of the human condition toward tribalism and in-group bias. It's an uglier side of human psychology, but it seems that even something as innocuous as what we choose to eat can bring out this inherent "us vs. them" mentality.

Join us on this episode of Objective:Health as we look into the phenomenon of diet dogmatism, exploring the psychology of identifying (too strongly) with what we choose to eat.

The overdiagnosis of cancer

For years, GreenMedInfo has been reporting on the overdiagnosis of cancer. Cancer overdiagnosis is one of the most serious and dangerous problems in medicine today. The over diagnosed cancer poses no threat. But the unnecessary chemotherapy and radiation, while offering no help, do pose the significant threat of stress, discomfort, illness and even possibly causing real cancers.


As that earlier reporting made clear, most studies indicate that cancer screening does not reduce the risk of dying from the cancer it is screening for (1). But it does introduce the risk of the harms caused by screening, false positives and overdiagnosis.

Perhaps the most serious story of overdiagnosis is thyroid cancer. For women, the risk of thyroid cancer overdiagnosis ranges from 50% to as high as 70-80% in the U.S., France, Italy and Australia. For men, the fear is not much lessened with overdiagnosis climbing to 45% in the U.S. and as high as 70% in some other countries (2).

Breast cancer is an almost equally terrifying concern. A systematic review of the research found that the risk of overdiagnosis of breast cancer is an incredible 52% (3). More recent research shows no improvement. In fact, the picture is getting worse. A 2014 study published in the Journal of the American Medical Association showed that ten years or more of regular mammograms leads to a false positive in over 60% of women (4).

Men face similar problems with prostate cancer. Though PSA screening for prostate cancer provides no benefit, since it does not reduce the rate of death, it does result in false positives in 12-13% of men who undergo the test three to four times (5).


Honey reduces risk of heart disease

Got a sweet tooth that you just can't squash? Relax! Nature has provided a healthy way to satisfy your sugar cravings. Put down the toxic white stuff and pick up a jar of pure, raw honey. Your heart will thank you for it

In a cooperative effort between researchers at the medical sciences departments of Iran's Isfahan University and Mashhad University, honey has been shown to aid the body in healthy processing of fats by decreasing the overall amount of cholesterol and fats in the bloodstream.[i] The study was published in August 2018 in the journal of the European Society for Clinical Nutrition and Metabolism (ESPEN), Clinical Nutrition ESPEN.

Researchers were inspired by previous studies that demonstrated honey's beneficial effects on cardiovascular disease symptoms. Their chief aim was to investigate whether the effect of honey consumption on overall lipids in the blood was markedly different than the effects of sucrose, or table sugar, on the blood lipid profiles of 60 young, healthy male subjects.

Good Fats Are Key to Heart Health

A lipid profile, also called a coronary risk panel, is a blood test that measures total blood triglycerides including high-density lipoproteins (HDL), often referred to as "good cholesterol," and low-density lipoproteins (LDL), commonly known as "bad cholesterol." In truth, there is only one "type" of cholesterol, a molecule that is incapable of dissolving in blood. In order to transport cholesterol to the various cells throughout the body, lipoproteins such as LDLs and HDLs act as cholesterol carriers.


Navigating viral storms and avoiding death

Boy in bed
It started with a light cough. He burped constantly, and complained of shortness of breath. Family members thought it was no big deal. The doctor said he seemed to have heart problems and suggested him to stay in the hospital. He appeared healthy except for a minor infection in one lung area.

Two weeks later, he was dead, with both lungs infected and organ failure. His doctors at the Wuhan Jinyintan Hospital determined the cause of death as "unknown pneumonia." It was days before Chinese health authorities identified the cause of the new viral pneumonia as 2019-nCoV, a coronavirus that first emerged in December in the commercial city of Wuhan, his home city.

This is a deadly virus, more deadly so far than the worst viral threats to date and they are locking people up in their own homes in China. For all the latest information see this video. Things are moving fast and events are looking to overtake the world's health officials, who this time are being aggressive in trying to control it, at least in China.

Brandon Smith writes, "I would not be surprised if we discover in the next two weeks that the death tally is in the thousands, and the sickness rate is actually in the hundreds of thousands. The fact that China has now quarantined over 50 million people in 16 cities suggests the danger is much higher than they have admitted. If this is the case, then at the very least, the Chinese economy is about to take a massive hit. If the virus doesn't spread, the economic damage will."

Statins trigger brain changes with devastating effects

brain in pill
Data from the CDC1 in 2017 show heart disease causes one death every 37 seconds in America and that it is the leading cause of death in the U.S. It created a financial burden of $219 billion in 2014 and 2015. Every 40 seconds someone has a heart attack. Those at higher risk are smokers and those who have high blood pressure, high blood cholesterol and/or diabetes.2

Since researchers believed cholesterol levels contribute greatly to heart disease, pharmaceutical companies focused on developing a drug that might be marketed to millions when they first began searching for a "cure" to what is known as "hardening of the arteries." After a historical journey beginning in the mid-20th century,3 the first statin drug was released in 1987 — lovastatin.

American Diabetes Association CEO manages her diabetes with a low-carb diet

Here's some highly encouraging news: the influential CEO of the American Diabetes Association (ADA) is on the record as a low-carb eater.

In a recent podcast interview that is setting the low-carb world abuzz, ADA CEO Tracy Brown said she successfully manages her own type 2 diabetes, and has come off all her insulin and three other medications, by avoiding sugar and carbs.

Commentators are calling it a pivotal "tipping point" and hugely significant milestone in the acceptance for low-carb eating for diabetes. It marks the first time a high-placed ADA official has described personal success with a low-carb diet.

Comment: This truly could be a major turn-around in the official advice given by the American Diabetes Association. To actually have the CEO giving merit to low carb diets for the management (cure?) of diabetes is nothing short of revolutionary.
