Eating protein from a greater variety of sources may lower risk of high blood pressure
Eating a balanced diet including protein from a greater variety of sources may help adults lower the risk of developing high blood pressure, according to new research published today in *Hypertension*, a peer-reviewed journal of the American Heart Association. Nearly half of the U.S. population has hypertension, or high blood pressure – one of the leading contributors to cardiovascular disease. When left untreated, high blood pressure damages the circulatory system and is a significant contributing factor to heart attack, stroke and other health conditions. “Nutrition may be an ... read more


Green Mediterranean diet: weight loss and cardiac risk reduction
The green Mediterranean diet (MED) has a striking effect on the microbial population of the human gut (i.e., the “gut microbiome”). In a large-scale clinical interventional trial- the DIRECT PLUS - the gut microbiome of green MED dieters was enriched with bacteria that are known to have a significant effect on human weight and glycemic control. A novel analysis revealed that the health-promoting effects, previously attributed to the green MED diet, are in fact mediated by the changes in the gut microbiome. The study was recently published in *Genome Medicine (* https://genomemedic... read more

Nordic diet lowers cholesterol and blood sugar – even if you don't lose weight
Berries, veggies, fish, whole grains and rapeseed oil. These are the main ingredients of the Nordic diet concept that, for the past decade, have been recognized as extremely healthy, tasty and sustainable. The diet can prevent obesity and reduce the risk of cardiovascular disease, type 2 diabetes, high blood pressure and high cholesterol. Until now, Nordic diet research has primarily been linked to the diet’s positive health effect following weight loss. But a new analysis conducted by University of Copenhagen researchers, among others, makes it clear that a Nordic diet has posi... read more

No short-term, statistically significant difference between calorie-matched fries and almonds on key health metrics
White potatoes — especially French fries — are often described in nutrition research literature and dietary guidance statements as having associations with obesogenic diets and as increasing chronic disease risk based on observational research findings. However, there is limited evidence from randomized controlled trials (RCTs) testing cause-and-effect relationships. Now, an RCT published in the *American Journal of Clinical Nutrition* demonstrates that adding a 300-calorie serving of French fries to one’s typical diet every day for a month does *not* result in differential weig... read more

Diet may play a role in development of pregnancy complications among Hispanic/Latina women
Diet may play a role in the development of dangerous high blood pressure in late pregnancy among some Hispanic/Latina women, according to preliminary research to be presented at the American Heart Association’s Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Conference 2022*.* The meeting will be held in person in Chicago and virtually Tuesday, March 1 – Friday, March 4, 2022, and offers the latest in population-based science related to the promotion of cardiovascular health and the prevention of heart disease and stroke. “Our study findings suggest that a diet with r... read more

Health: low-meat and meat-free diets associated with lower overall cancer risk

Eating meat five times or less per week is associated with a lower overall cancer risk, according to a study published in the open access journal *BMC Medicine*. Cody Watling and colleagues from the University of Oxford, UK investigated the relationship between diet and cancer risk by analysing data collected from 472,377 British adults who were recruited to the UK Biobank between 2006 and 2010. Participants, who were aged between 40 and 70 years, reported how frequently they ate meat and fish and the researchers calculated the incidence of new cancers that developed over an aver... read more

Two new studies find positive health outcomes of mango consumption
Mangos associated with better quality diets, lower blood sugar, and less inflammation As low fruit and vegetable consumption continues to contribute to diet-related chronic diseases like diabetes and heart disease, two new research studies find regular mango consumption may improve diets and help manage key risk factors that contribute to chronic disease. Specifically, these new studies report findings in two areas: 1) mango consumption is associated with better overall diet quality and intake of nutrients that many children and adults lack at optimum levels, and 2) snackin... read more

A high-fiber diet may reduce risk of dementia
We're always hearing that we should eat more fiber. It's known to be vitally important for a healthy digestive system and also has cardiovascular benefits like reduced cholesterol. Now, evidence is emerging that fiber is also important for a healthy brain. In a new study published this month in the journal *Nutritional Neuroscience*, researchers in Japan have shown that a high-fiber diet is associated with a reduced risk of developing dementia. "Dementia is a devastating disease that usually requires long-term care," says lead author of the study Professor Kazumasa Yamagishi. "We... read more

Eating vegetables does not protect against cardiovascular disease

*Previous positive studies may not have sufficiently corrected for confounding socio-economic and lifestyle factors, suggests new analysis* A sufficient intake of vegetables is important for maintaining a balanced diet and avoiding a wide range of diseases. But might a diet rich in vegetables also lower the risk of cardiovascular disease (CVD)? Unfortunately, researchers from the Nuffield Department of Population Health at the University of Oxford, the Chinese University of Hong Kong, and the University of Bristol found no evidence for this. That the consumption of vegetables mig... read more


AGING

Seniors with memory issues take multiple meds
Some 58% of seniors with probable or possible dementia had otherwise good to excellent health, yet more than half of the total took six or more regular medications – a habit that may, at best, strain insurance costs and budgets, and at worst may result in adverse drug interactions and poor outcomes, and even exacerbate cognitive symptoms. But far from the seniors refusing to reduce their medications, which includes prescribed and over-the-counter drugs as well as supplements, a new study led by UC San Francisco reveals that 87% of them responded that they would be willing to st... read more

Physical activity may protect your brain as you age
We all know we should exercise and eat healthy. But doing that isn’t just good for maintaining your figure as you age. New research from the University of Georgia shows that physical activity could help protect your cognitive abilities as you age. And it doesn’t have to be intense exercise to make an impact. “This finding isn’t saying, ‘If you’re older, you need to go out there and start running marathons,’” said Marissa Gogniat, lead author of the study and a recent doctoral graduate in psychology from the Franklin College of Arts and Sciences. “This is saying if you get more st... read more

Physical fitness linked to lower risk of Alzheimer’s disease
– People who are more physically fit are less likely to develop Alzheimer’s disease than people who are less physically fit, according to a preliminary study released today, February 27, 2022, that will be presented at the American Academy of Neurology’s 74th Annual Meeting being held in person in Seattle, April 2 to 7, 2022 and virtually, April 24 to 26, 2022. “One exciting finding of this study is that as people’s fitness improved, their risk of Alzheimer’s disease decreased—it was not an all-or-nothing proposition,” said study author Edward Zamrini, MD, of the Washington VA M... read more

Study shows long-term pet ownership linked to slower decline in cognition over time
– Owning a pet, like a dog or cat, especially for five years or longer, may be linked to slower cognitive decline in older adults, according to a preliminary study released today, February 23, 2022, that will be presented at the American Academy of Neurology’s 74th Annual Meeting being held in person in Seattle, April 2 to 7, 2022 and virtually, April 24 to 26, 2022. “Prior studies have suggested that the human-animal bond may have health benefits like decreasing blood pressure and stress,” said study author Tiffany Braley, MD, MS, of the University of Michigan Medical Center in... read more

Daily activities like washing dishes reduced heart disease risk in senior women
Seniors take note, running or brisk walking is not the only way to reduce the risk of heart disease. Simply being “up and about” performing routine activities, referred to as daily life movement, including housework, gardening, cooking and self-care activities like showering can significantly benefit cardiovascular health. Compared to women with less than two hours per day of daily life movement, those women with at least four hours of daily life movement had a 43% lower risk of cardiovascular disease, 43% lower risk of coronary heart disease, 30% lower risk of stroke and notably... read more

Physical function and medicines linked to risk of falling and fractures
In older women, inability to stand on one leg for more than a few seconds is a risk factor for fracture. Another physical test yields similar results. Moreover, SSRIs can be linked to relatively poor physical function, a University of Gothenburg thesis shows. Osteoporosis, with its associated fractures, is a growing public health problem that causes suffering and heavy costs in health care. In her doctoral thesis at Sahlgrenska Academy, University of Gothenburg, specialist doctor Berit Larsson describes her investigation of potential for predicting osteoporosis (bone fragility) a... read more


EXERCISE AND AGING

Exercise can help older adults retain their memories
We all know exercise is good for us, but that still leaves plenty of questions. How much exercise? Who benefits the most? And when in our lives? New research led by University of Pittsburgh psychologists pools data from dozens of studies to answer these questions, showing that older adults may be able to prevent declines in a certain kind of memory by sticking to regular exercise. “Everyone always asks, ‘How much should I be exercising? What’s the bare minimum to see improvement?’ ” said lead author Sarah Aghjayan, a Clinical and Biological Health Psychology PhD student in the ... read more

30-60 mins of weekly muscle strengthening activity linked to 10-20% lower death risk
*From all causes and from cardiovascular disease, diabetes, and cancer, in particular But no conclusive evidence that more than an hour of this activity is more effective* Between 30 and 60 minutes of muscle strengthening activity every week is linked to a 10-20% lower risk of death from all causes, and from cardiovascular disease, diabetes, and cancer, in particular, finds a pooled data analysis of the available evidence, published online in the *British Journal of Sports Medicine.* The findings are independent of aerobic exercise. But the analysis points to a J-shaped curve ... read more

High levels of lifelong exercise seem to counteract deterioration of fat tissue
Fat tissue plays an important role in human health. However, our fat tissue loses function as we age, which can lead to type 2 diabetes, obesity, cancer and other ailments. High levels of lifelong exercise seem to counteract this deterioration. This, according to research at the University of Copenhagen, where biologists studied the link between aging, exercise and fat tissue function in Danish men. How well does your fat function? It isn’t a question that one gets asked very often. Nonetheless, research in recent years suggests that the function of our fat tissue, or adipose tiss... read more

20 mins of daily exercise at 70 may best stave off major heart disease in late old age
Twenty minutes of daily moderate to vigorous exercise in early old age (70-75) may best stave off major heart disease, including heart failure, in late old age (80+), suggests research published online in the journal *Heart*. The findings reinforce the maxim of ‘better late than never,’ when it comes to exercise, but earlier on in older age is better still, concludes a linked editorial. It’s no secret that physical activity is associated with a lower risk of cardiovascular disease and a longer life, irrespective of gender and ethnicity, with the benefits accruing in tandem with t... read more

New findings on how many daily walking steps needed for longevity benefit
A meta-analysis of 15 studies involving nearly 50,000 people from four continents offers new insights into identifying the amount of daily walking steps that will optimally improve adults’ health and longevity – and whether the number of steps is different for people of different ages. The analysis represents an effort to develop an evidence-based public health message about the benefits of physical activity. The oft-repeated 10,000-steps-a-day mantra grew out of a decades-old marketing campaign for a Japanese pedometer, with no science to back up the impact on health. Led by Uni... read more

Resistance exercise may be superior to aerobic exercise for getting better ZZZs
Resistance exercise may be superior to aerobic exercise as a way to get better sleep, and sleep is important for cardiovascular health, according to preliminary research to be presented at the American Heart Association’s Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Conference 2022*.* The meeting will be held in-person in Chicago and virtually Tuesday, March 1 – Friday, March 4, 2022, and offers the latest in population-based science related to the promotion of cardiovascular health and the prevention of heart disease and stroke. “It is increasingly recognized tha... read more

Cocoa does not appear to reduce exercise-related digestive distress
Impressive athleticism was on display during the Winter Olympics, but being at the top of one’s game doesn’t necessarily protect against digestive distress resulting from exercise. Surprisingly, some people are adding cocoa to their diets to reduce these symptoms. Now, researchers in ACS’ *Journal of Agricultural and Food Chemistry* report that long-term daily consumption of cocoa doesn’t appear to improve exercise-related digestive issues in male athletes and induces only minimal changes to their gut microbiomes. Performing vigorous or intense exercise can cause digestive upset f... read more



GENERAL HEALTH

Common houseplants can improve air quality indoors
Ordinary potted house plants can potentially make a significant contribution to reducing air pollution in homes and offices, according to new research led by the University of Birmingham and in partnership with the Royal Horticultural Society (RHS). During a series of experiments monitoring common houseplants exposed to nitrogen dioxide (NO2) – a common pollutant – researchers calculated that in some conditions, the plants could be able to reduce NO2 by as much as 20 per cent. The researchers tested three houseplants commonly found in UK homes, easy to maintain and not overly ex... read more

Blood pressure reading is more accurate at home
Blood pressure measurements routinely taken at home are more likely to provide the basis for accurate diagnoses of hypertension than those taken in a clinic setting, according to a new study led by Kaiser Permanente investigators. The findings come from a randomized controlled trial of 510 adults who visited one of 12 Kaiser Permanente primary care centers in Western Washington between 2017 and 2019 published today in the *Journal of General Internal Medicine.* “Blood pressure varies a lot over the day — about 30 points systolic — and 1 or 2 measurements in clinic may not reflec... read more

Best chance for battling menopausal weight gain is during perimenopause
Most women going through menopause complain about the added weight. Menopause is often accompanied by accelerated adverse changes in body composition, hot flashes, and an increased risk of such chronic diseases as osteoporosis and heart disease. A new study suggests that lifestyle interventions aimed at managing these problems are most valuable during perimenopause. Study results are published online today in *Menopause*, the journal of The North American Menopause Society (NAMS). Much focus is on the adverse symptoms of menopause. The reality is that many of the changes associate... read more

Nostalgia can relieve pain
 Reflecting on fond memories goes a step beyond making you feel warm and fuzzy: nostalgia can reduce pain perception. Nostalgia decreases activity in pain-related brain areas and decreases subjective ratings of thermal pain, according to research recently published in *JNeurosci*. Researchers from the Chine... read more

Lactoferrin supplement offers anti-SARS-CoV-2 efficacy

As the COVID-19 pandemic continues to claim lives around the world, dairy scientists may have a surprising role to play. In a new report published in the *Journal of Dairy Science®*, scientists from the University of Michigan (Ann Arbor, MI, USA) and Glanbia PLC Research and Development (Twin Falls, ID, USA) have collaborated to investigate the antiviral properties of cow milk protein against variants of SARS-CoV-2, the virus behind the illness. The protein in question is lactoferrin, found in the milk of most mammals. Bovine lactoferrin, from cow milk, has bioactive characteristi... read more

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections
New research has found significant differences between the two types of vitamin D, with vitamin D2 having a questionable impact on human health. However, the study found that vitamin D3 could balance people’s immune systems and help strengthen defences against viral infections such as Covid-19. In a collaborative study by the Universities of Surrey and Brighton, researchers investigated the impact of vitamin D supplements – D2 and D3 – taken daily over a 12-week period on the activity of genes in people's blood. Contrary to widely held views, the research team discovered that b... read more


SLEEP

Sleep apnea accelerates aging, but treatment may reverse it
Obstructive sleep apnea (OSA) affects 22 million people in the U.S. and is linked to a higher risk of hypertension, heart attacks, stroke, diabetes and many other chronic conditions. But now researchers from the University of Missouri School of Medicinehave found that untreated OSA also accelerates the biological aging process and that appropriate treatment can slow or possibly reverse the trend. Age acceleration testing involves a blood test that analyzes DNA and uses an algorithm to measure a person’s biological age. The phenomenon of a person’s biological age surpassing their ... read more

COVID

Third vaccine dose critical for protecting populations against omicron variant
mRNA vaccines are highly effective in preventing covid-19 associated hospital admissions related to the alpha, delta, and omicron variants. But three doses are needed to achieve a similar level of protection against omicron that two doses provide against the delta and alpha variants, finds a large US study published by* The BMJ *today. The results also show that, although severity of disease among patients admitted to hospital is lower with the omicron versus delta variant, patients with omicron are still at risk of critical illness and death. Understanding covid-19 variants an... read more
