Eating more nutritious, plant-based foods is heart-healthy at any age, according to two research studies published today in the *Journal of the American Heart Association*, an open access journal of the American Heart Association. In two separate studies analyzing different measures of healthy plant food consumption, researchers found that both young adults and postmenopausal women had fewer heart attacks and were less likely to develop cardiovascular disease when they ate more healthy plant foods. The American Heart Association Diet and Lifestyle Recommendations suggest an ove... read more
Frequent consumption of peanuts by cancer patients may increase risk of cancer spread
p A study by University of Liverpool researchers has identified new factors accompanying previous findings that frequent consumption of peanuts by cancer patients could increase risk of cancer spread. The study, published in *Carcinogenesis* shows that Peanut agglutinin (PNA) – a carbohydrate-binding protein that rapidly enters into the blood circulation after peanuts are eaten – interacts with blood vascular wall (endothelial) cells to produce molecules called cytokines. The cytokines in question, IL-6 and MCP-1 are well-known promoters of cancer metastasis. The increased cytokine p... read more
American youth between two and 19 years-old have the lowest measures of diet quality compared to other age groups;[1] and nutrition thought leaders have called for effective strategies to reverse this trend and improve adherence to dietary recommendations. Now, new research published in *Nutrients* finds U.S. adolescents who eat potatoes have higher quality diets than those who do not consume potatoes, regardless of how the potatoes are processed or prepared. Compared to no potato consumption, results showed that eating potatoes in any form (baked, boiled, mashed, in mixed dishes... read more
In the most comprehensive analysis yet of ketogenic (keto) diets, a review in *Frontiers in Nutrition* finds keto diets place pregnant women and kidney disease patients at risk of adverse health effects. The review, Ketogenic Diets and Chronic Disease: Weighing the Benefits Against the Risks, also found that for most people, the possible long-term risks of the keto diet, including heart disease, cancer, diabetes, and Alzheimer's disease, outweigh its possible benefits. “The typical keto diet is a disease-promoting disaster,” says lead review author Lee Crosby, RD, nutrition educat... read more
A new study from the University of Kansas in the journal *Appetite* examines people’s choices when confronted with an all-you-can-eat buffet. It turns out that the food we choose to heap on our plates might predict our chances of having higher weight gain or obesity. The researchers focused on foods defined as “hyperpalatable” — dividing this category into carbohydrate and sodium (CSOD) foods or fat and sodium (FSOD) foods — and compared them with high-energy dense and ultra-processed foods. “Hyperpalatable foods have combinations of ingredients that can enhance a food’s palatabi... read more
Excess coffee: A bitter brew for brain health
It's a favourite first-order for the day, but while a quick coffee may perk us up, new research from the University of South Australia shows that too much could be dragging us down, especially when it comes to brain health. In the largest study of its kind, researchers have found that high coffee consumption is associated with smaller total brain volumes and an increased risk of dementia. Conducted at UniSA's Australian Centre for Precision Health at SAHMRI and a team of international researchers*, the study assessed the effects of coffee on the brain among 17,702 UK Biobank parti... read more
Research News In the largest study of its kind, an investigation by UC San Francisco has found no evidence that moderate coffee consumption can cause cardiac arrhythmia. In fact, each additional daily cup of coffee consumed among several hundred thousand individuals was associated with a 3 percent lower risk of any arrhythmia occurring, including atrial fibrillation, premature ventricular contractions, or other common heart conditions, the researchers report. The study included a four-year follow up. The paper is published July 19, 2021, in *JAMA Internal Medicine*. "Coffee is t... read more
A more complex, holistic and non-reductionist approach to defining carbohydrate quality is needed Carbohydrates have traditionally been the largest source of energy intake for much of the world's population1. However, without a standard definition for carbohydrate quality, some foods that contain carbohydrates are often stigmatized based on isolated and reductionist assessment methods that fail to consider their contributions to nutrient intakes and balanced, healthy diets. A new perspective piece, published in *Advances in Nutrition*, brings to light the pressing need to defi... read more
A higher intake of ultra-processed food is associated with higher risk of inflammatory bowel disease (IBD), finds a study published by *The BMJ* today. Ultra-processed foods include packaged baked goods and snacks, fizzy drinks, sugary cereals, ready meals containing food additives, and reconstituted meat and fish products -- often containing high levels of added sugar, fat and salt, but lacking in vitamins and fibre. Inflammatory bowel disease (IBD) is more common in industrialised nations and it is thought that dietary factors might play a role, but data linking ultra-processe... read more
PHYSICIANS COMMITTEE FOR RESPONSIBLE MEDICINE A new study, published by the North American Menopause Society in the journal *Menopause,* found a plant-based diet rich in soy reduces moderate-to-severe hot flashes by 84%, from nearly five per day to fewer than one per day. During the 12-week study, nearly 60% of women became totally free of moderate-to-severe hot flashes. Overall hot flashes (including mild ones) decreased by 79%. The study, called the WAVS trial--the Women's Study for the Alleviation of Vasomotor Symptoms-shows that diet changes can be much more powerful for tre... read more
One in four new breast cancers and one in five colon cancers in Canada attributed to alcohol CENTRE FOR ADDICTION AND MENTAL HEALTH Alcohol drinking caused nearly 7,000 cases of cancer in Canada in 2020. Breast cancer made up almost 1 in 4 of the new cases attributable to alcohol. CREDIT World Health Organization's (WHO) International Agency for Research on Cancer (IARC) A new study from the World Health Organization's (WHO) International Agency for Research on Cancer (IARC), published in the journal *Lancet Oncology*, has found an association between alcohol and a substan... read more
Study in middle- to older-aged adults suggests whole grains may protect against heart disease Research News Middle- to older-aged adults who ate at least three servings of whole grains daily had smaller increases in waist size, blood pressure, and blood sugar levels over time compared to those who ate less than one-half serving per day, according to new research. Published July 13, 2021, in the *Journal of Nutrition*, the study by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University examined how whole- and refined-grain intake over time... read more
A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers at the Stanford School of Medicine. In a clinical trial, 36 healthy adults were randomly assigned to a 10-week diet that included either fermented or high-fiber foods. The two diets resulted in different effects on the gut microbiome and the immune system. Eating foods such as yogurt, kefir, fermented cottage cheese, kimchi and other fermented vegetables, vegetable brine drinks, and kombucha tea led to an increase in overall microbial divers... read more
