The skeptical cardiologist was asked to give a lecture in July on diet to the cardiology fellows in our training program at Saint Louis University. Needless to say, I didn’t hew to current recommendations from the American Heart Association or the Dietary Guidelines for Americans. For example, these recommendations are still promoting the narrative that…
Brussels chicory might help stabilize atherosclerotic plaques in mice by reducing intestinal permeability and gut microbial LPS production. This study provides a promising approach to slow the progression of atherosclerosis.
Makes you wonder if improving your diet will help.
Many adults can achieve remission of type 2 diabetes with a primary intervention consisting of a diet that emphasizes whole, plant-based foods, according to a new publication from the American College of Lifestyle Medicine (ACLM).
“The first thing we noticed was that the small intestine increases greatly in size on the high-calorie diet,” says study leader Anika Böttcher. “Together with Fabian Theis’ team of computational biologists at Helmholtz Munich, we then profiled 27,000 intestinal cells from control diet and high fat/high sugar diet-fed mice. Using new machine learning techniques, we thus found that intestinal stem cells divide and differentiate significantly faster in the mice on an unhealthy diet.” The researchers hypothesize that this is due to an upregulation of the relevant signaling pathways, which is associated with an acceleration of tumor growth in many cancers. “This could be an important link: Diet influences metabolic signaling, which leads to excessive growth of intestinal stem cells and ultimately to an increased risk of gastrointestinal cancer,” says Böttcher.
The calories that children and adolescents consumed from ultraprocessed foods jumped from 61% to 67% of total caloric intake from 1999 to 2018, according to a new study from researchers at the Friedman School of Nutrition Science & Policy at Tufts University. Published August 10, 2021, in JAMA, the study analyzed dietary intake from 33,795 children and adolescents nationwide.
The largest spike in calories came from such ready-to-eat or ready-to-heat dishes as takeout and frozen pizza and burgers: from 2.2% to 11.2% of calories. The second largest spike in calories came from packaged sweet snacks and desserts, the consumption of which grew from 10.6% to 12.9%.
Frozen pizza and burgers? Is this a problem?
Findings In this serial cross-sectional study of nationally representative data from 33 795 US youths aged 2-19 years, the estimated percentage of total energy consumed from ultraprocessed foods increased from 61.4% to 67.0%, whereas the percentage of total energy consumed from unprocessed or minimally processed foods decreased from 28.8% to 23.5%.
Older people with prediabetes who followed a diet rich in sardines for 1 year show significant reductions in risk of developing type 2 diabetes compared with those placed on a similarly healthy diet but without the sardines, results from a new randomized trial show.
“A 1-year, sardine-enriched type 2 diabetes-preventive diet in an elderly population with prediabetes exerts a greater protective effect against developing type 2 diabetes and cardiovascular events, by improving anthropometric parameters, blood chemistry profile, lipid composition in erythrocytes membranes, and metabolomics data,” report the authors in research published in Clinical Nutrition by Diana Díaz-Rizzolo, PhD, of the Hospital Clinic of Barcelona, Spain, and colleagues.
When the researchers looked at the functions of the genes in the three sample types, they found that the ancient and non-industrial groups contained a diverse array of genes linked with the breakdown of starches. This indicates that the diets of the ancient and non-industrialised populations were high in complex carbohydrates, like vegetables and grains.
Researchers examined data from over 50,000 people residing in Denmark taking part in the Danish Diet, Cancer, and Health Study over a 23-year period. They found that people who consumed the most nitrate-rich vegetables had about a 2.5 mmHg lower systolic blood pressure and between 12 to 26 percent lower risk of heart disease.
Lead researcher Dr Catherine Bondonno from ECU’s Institute for Nutrition Research said identifying diets to prevent heart disease was a priority.
“Our results have shown that by simply eating one cup of raw (or half a cup of cooked) nitrate-rich vegetables each day, people may be able to significantly reduce their risk of cardiovascular disease,” Dr Bondonno said.
