More research advise reducing consumption of ultra-processed foods, cautioning the public against excessive intake of items like biscuits, cakes, and crisps.
Recently, researchers contributed further evidence, releasing two studies revealing a nearly 25% higher risk of fatal heart attack or stroke associated with excessive consumption. However, the nature of ultra-processed foods remains a question.
In-Depth Definition of Ultra=-Processed Foods
Food processing involves modifying raw ingredients to make sure it is safe to eat in ways, like pasteurization, or to extend shelf life through freezing, or even to enhance its taste by adding sugar, salt, or fat.
In 2009, Carlos Monteiro developed the Nova system, which classifies foods into four groups to help study food in relation to processing. It has been widely used to explore the diet-disease link since then.
Unprocessed or minimally processed foods retain natural form, sometimes with inedible parts removed. Examples are fruit, vegetables, meat, eggs, and milk. On the other hand, processed ingredients like oil, butter, sugar, and salt are utilized in cooking, not consumed alone.
In the processed foods category, modifications enhance taste and shelf life. Examples include canned vegetables, fish, fresh bread, and cheese.
Ultra-processed foods garner substantial focus. Extensively processed with added fats, colors, and preservatives include items like chocolates, cakes, and snacks. Surprisingly, certain low-fat yogurts, mass-produced bread, cereals, and plant-based milk also fit this classification.
Ultra-Processed Food Threatens Heart Health
Ultra-processed foods contain additives like preservatives and sweeteners absent from common kitchen supplies, granting them extended shelf lives. Examples encompass ice cream, mass-produced bread, flavored yogurts, soft drinks, cereals, and convenience foods.
Experts warn that the UK faces a severe health crisis due to excessive consumption of ultra-processed foods. Two studies reveal a 24% heightened heart attack risk and a 39% increased probability of dangerously high blood pressure for those consuming mass-produced items. Researchers from Australia and China label this as strong evidence of the danger of ultra-processed foods. Additionally, a 15-year University of Sydney study of 10,000 women found a 39% higher likelihood of high blood pressure among those with a higher intake of ultra-processed foods.
Nonetheless, like previous research, these studies are observational, lacking the capacity to establish direct causation between ultra-processed foods and health outcomes.
Experts propose that confounding factors, such as socio-economic disparities leading to poorer health habits, exercise, and smoking, could be influencing the results of those who consume such foods in excess.
Professor Gunter Kuhnle from the University of Reading, a nutritionist, explained that "ultra-processed" is a popular term linking diet and health. Many studies attempt to demonstrate these connections. Bread and meat items are sometimes erroneously categorized as "ultra-processed."
He further emphasized the importance of comprehending the link between diet and cognitive function, underscoring the need for recommendations grounded in robust data, factoring in risks, benefits, costs, and broader health implications.
