New studies have shown that increased consumption of processed foods significantly increases the risk of cardiovascular disease. In addition, the mortality rate was 62% higher over a ten-year period for young people who frequently consume highly processed foods. A recent study has established a clear causal relationship between the consumption of highly processed foods and obesity. Now, Brazilian-French scientists have published a study in the BMJ journal that further confirms the negative health effects of processed foods. The researchers analyzed the eating habits of over 100,000 French adults, categorizing 3,300 different foods according to their level of processing. The long-term study observed the health and nutrition of the participants from 2009 to 2018, with an average of 5.7 years between each dietary survey. The results showed that individuals who consumed high levels of processed foods, such as frozen pizza, were more likely to experience cardiovascular disease. While the observational study does not prove causality, the authors suggest that additives and processing materials in processed foods could have negative effects on health.
A second study by Spanish scientists, also published in the BMJ journal, investigated whether processed foods increase mortality rates in addition to the known consequences such as obesity, high blood pressure, and increased cancer risk. The researchers observed the eating habits of approximately 20,000 Spanish students over a ten-year period to determine whether there was a correlation between the consumption of processed foods and mortality rates. According to the authors of the study, “the results show that higher consumption of highly processed foods (more than four servings per day) was associated with a 62% increased risk of all-cause mortality compared to lower consumption.” However, causality could not be established in this case, as other factors that could also influence mortality rates were not included in the analysis. Further studies are needed to confirm the likely causal relationship.
These studies provide further evidence of the negative health effects of processed foods. While the results do not prove causality, they suggest that reducing the consumption of processed foods could have significant health benefits. It is important to note that processed foods are often high in calories, sugar, and salt, and low in nutrients, making them a poor choice for a healthy diet. Experts recommend choosing whole, unprocessed foods whenever possible to maintain good health.
