For people with diabetes, healthy eating is not enough if their diet is rich in ultra-processed foods
An Italian research by the I.R.C.C.S. Neuromed shows that the consumption of highly processed foods, often industrially manufactured, increases the risk of death for people with type 2 diabetes, regardless of the nutritional quality of their diet

The very first rule for people diagnosed with type 2 diabetes is to eat a healthy nutritious diet. Attention to ingested calories, as well as nutrients contained in various foods, become integral parts of a diabetic person's life. However, this might not be enough: an important role in determining the future health status of people with this condition could be played by the degree of processing of foods that end up on the dish. These products are described as "ultra-processed" and are associated with adverse health outcomes, as reported in general population studies.
A study conducted by the Department of Epidemiology and Prevention at the I.R.C.C.S. Neuromed in Pozzilli, Italy, published in the American Journal of Clinical Nutrition, has now analyzed whether consumption of ultra-processed foods could be a risk factor also for more vulnerable people, such as those suffering from type 2 diabetes. Results show that a high consumption of ultra-processed foods is associated with a substantial increase in the risk of mortality, especially from cardiovascular diseases, regardless of the nutritional quality of the diet, as reflected by adherence to the Mediterranean Diet.
Ultra-processed foods are products that have undergone often intense processing, made, in part or entirely, with substances that are not usually used in the kitchen (e.g., hydrolyzed proteins, maltodextrins, hydrogenated fats) and generally contain several food additives, such as colorings, preservatives, antioxidants, flavor enhancers and sweeteners. Their main purpose is not to improve the nutritional properties of food but rather to enhance its taste, appearance and shelf life. Packaged snacks, fizzy and sugary drinks, ready-to-eat meals and fast-food come immediately to the mind. It's true, but they don't represent the whole situation: the level of processing, as well as the use of additives, are features that can also be found in foods that we might consider healthful, such as fruit yogurt, breakfast cereals, crackers, and a large part of meat substitutes.
The Italian researchers analyzed data from the large Moli-sani Study and specifically examined 1,066 participants who were affected by type 2 diabetes at study entry in 2005-2010.
"Over an average follow-up of 12 years - says Marialaura Bonaccio, epidemiologist of the Department of Epidemiology and Prevention of the IRCCS Neuromed of Pozzilli and first author of the study - we observed that a diet rich in ultra-processed foods exposed people with diabetes to a greater risk of death. Participants reporting a higher consumption of ultra-processed foods had 60% increased risk of dying from any cause, compared to people consuming less of these products. The risk of mortality from cardiovascular diseases, which is a leading cause of death for people with diabetes, was more than doubled."
"One of the most interesting results of this study - says Licia Iacoviello, Director of the Department and full professor of Hygiene at the University of Insubria of Varese and Como - is that the increased risk linked to ultra-processed foods was observed even when participants reported a good adherence to the Mediterranean Diet. These findings suggest that if the dietary share of ultra-processed foods is high, the potential advantages of a healthful Mediterranean Diet risk to be overlooked”.
"These results - comments Giovanni de Gaetano, President of the IRCCS Neuromed of Pozzilli - may have important implications for future dietary guidelines to manage type 2 diabetes. In addition to the adoption of a diet based on well-known nutritional requirements, dietary recommendations should also suggest limiting the consumption of ultra-processed foods as much as possible. In this context, and not only for people with diabetes, the front-of-pack nutrition labels should also include information on the degree of food processing".
The Moli-sani Study
Started in March 2005, it involves about 25,000 citizens living in the Molise region. The aim is to learn about environmental and genetic factors underlying cardiovascular disease, cancer and degenerative disorders. . The Moli-sani Study, now based at the I.R.C.C.S. Neuromed, has transformed an entire Italian region in a large research lab.

About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence reported in the journal Current Biology on July 26, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.

The United States has more than 10 times the number of mass shooting incidents than other developed countries, yet little research has shown the distribution and types of shootings, geographically.
“I’m constantly asked, ‘What is public health doing about the rise in mass shootings?” says Leslie Barnard, MPH, a student working with the University of Colorado School of Medicine’s Firearm Injury Prevention Initiative.
Barnard, a doctoral candidate in the Department of Epidemiology in the Colorado School of Public Health at the CU Anschutz Medical Campus, wanted to find answers to address public ...

Eighty-two percent of child deaths in low-income countries could be prevented, according to a study from the international CHAMPS network published in JAMA Network Open. The study, which used the minimally invasive autopsy technique developed by the Barcelona Institute for Global Health (ISGlobal), found an infectious agent in 87% of cases and identified malnutrition as the most common underlying cause of death.
Ninety-nine percent of deaths in children under five years of age occur in low- and middle-income countries. "If we want to prevent these deaths, we need to know the causes, but the problem is that we lack reliable data," says Quique Bassat, ...

The El Niño–Southern Oscillation (ENSO) is the Earth's most consequential interannual climate fluctuation. Alternating irregularly between warm El Niño and cold La Niña phases, it brings shifts in ocean surface temperature and disrupts wind and rainfall patterns across the tropics.
Unlike El Niño, which usually lasts one year, La Niña tends to develop after an El Niño and lasts for two consecutive years or more. This is known as a multiyear La Niña event and exerts prolonged and aggregated impacts, such as increased wildfires, flooding, and altered ...

Earth is truly unique among our Solar System’s planets. It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of life.
Plate tectonics describes the movement and interaction of tectonic plates on Earth’s surface. This movement is driven by the very slow creeping motion of Earth's mantle, called convection, which carry heat from the interior to our planet's ...
