All relevant units: Diet is better for metabolic health and anti-aging

Modifying diet may be more effective than taking drugs at controlling conditions such as diabetes, stroke and heart disease, according to an Australian preclinical study. The study showed that nutrition, including total calories and macronutrient balance, has a greater impact on aging and metabolic health than the three commonly used diabetes and anti-aging drugs. The results were published in Cell Metabolism. The study builds on the team's pioneering work in mice and humans, demonstrating the protective effects of diet and specific combinations of protein, fat, and carbohydrates on the risk of aging, obesity, heart disease, immune dysfunction, and metabolic diseases such as type 2 diabetes. There has been an ongoing effort to find drugs that improve metabolic health and aging without changing diet. "Diet is good medicine. However, drugs are currently administered without considering whether and how they can interact with dietary components - even though these drugs act in the same way and nutritional signaling pathways as diet." Professor Stephen Simpson, corresponding author of the paper and academic director of the Charles Perkins Centre at the University of Sydney. So the researchers set out to see whether drugs or diets were more effective at reshaping nutrient perception and other metabolic pathways, and whether interactions between drugs and diets made them more effective. The team designed a complex mouse study that included 40 different approaches, each with different amounts of protein, fat and carbohydrates, calories and drugs. The study was designed to examine the effects of three anti-aging drugs on the liver, a key organ that regulates metabolism. A key strength of the study is the use of a nutritional geometric framework developed by Simpson and colleague David Raubenheimer. This framework allows researchers to consider how mixtures and interactions of different nutrients affect health and disease, rather than focusing on any one nutrient in isolation - a limitation of other nutrition studies. "We found that diet has a much stronger effect than drugs. Drugs largely suppress people's responses to diet rather than reshape them." "Given that humans and mice essentially share the same nutritional signaling pathways, the study suggests that people who change their diet to improve their metabolic health may have better results than if they were taking a drug," Simpson said. The findings help to understand the mechanisms between what we eat and how we age. Studies have found that calorie intake and the balance of macronutrients (protein, fat, and carbohydrates) in the diet have a big impact on the liver. Protein and total calorie intake have a particularly large impact on metabolic pathways and the basic processes that control cell function. For example, the amount of protein consumed affects the activity of the mitochondria, the part of the cell that produces energy. This creates a downstream effect, as the intake of protein and dietary energy affects the accuracy with which cells convert their genes into different proteins (which help cells function properly and make new cells), both of which are fundamental processes involved in aging. Drugs, by contrast, work primarily by inhibiting the cells' metabolic response to diet, rather than fundamentally reshaping them. However, the researchers also found some more specific interactions between the biochemical effects of drugs and dietary components. One anti-aging drug had a greater effect on cellular changes caused by dietary fats and carbohydrates, while a cancer drug and another diabetes drug both blocked the effects of dietary proteins on energy-producing mitochondria. David Le Couteur, one of the authors of the paper and a professor at the Charles Perkins Center, said that although the study is very complex, it shows how important it is to look at many different diets at once, rather than just comparing several different diets. "We all know that what we eat affects health, but this study shows that food can significantly affect many processes in the cells of the human body." This gives us insight into how diet affects health and aging."
