Let's see what scientists say about our diet.
Researchers enrolled a diverse group of adults (>18 years old), adolescents (aged 11-20) and school age children (3-15 years old). They collected receipts from participants to calculate the calorie content of their meals, and they administered a short questionnaire which included a question asking participants to estimate the calorie content of their meal. Parents provided answers for the school age children. The final sample size was 1877 adults, 1178 adolescents and 330 school age children.
A University of Alabama at Birmingham (UAB) study suggests that the Mediterranean diet, which emphasizes consuming foods that contain omega-3 fatty acids found in fish, chicken and salad dressing, and avoiding saturated fats, meat and dairy foods, may be linked to preserving memory and thinking abilities. However, the same association was not found in people with diabetes. The research is published in the April 30, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
According to a study published in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences, a baseline adherence to a Mediterranean diet (MeDiet) is associated with a lower risk of hyperuricemia, defined as a serum uric acid (SUA) concentration higher than 7mg/dl in men and higher than 6mg/dl in women.
Data from a new study of British adults suggest that adherence to a "Western-style" diet (fried and sweet food, processed and red meat, refined grains, and high-fat dairy products) reduces a person's likelihood of achieving older ages in good health and with higher functionality. Study results appear in the May issue of The American Journal of Medicine.
Heart disease is the single largest cause of death in developed countries, and is responsible for 65,000 deaths each year in the UK alone. The new findings, published in the American Journal of Clinical Nutrition, suggest that a vegetarian diet could significantly reduce people's risk of heart disease.
