We’ve all heard that breakfast is the most important meal of the day, but it’s not just about making sure you eat something in the morning. The portion size and the nutritional value of what you eat matter just as much, especially for older adults who are at risk for heart disease. New research shows that getting the right balance is key to maintaining good health as we age. (Also read: New study reveals each cigarette shortens life by 20 minutes; women are at greater risk )
Spanish researchers explored how the calorie content and nutritional quality of breakfast impact long-term cardiovascular health, highlighting the importance of healthy breakfast habits. “Promoting healthy breakfast routines can reduce the risk of metabolic syndrome and chronic diseases, improving overall quality of life,” says Karla-Alejandra Pérez-Vega, a researcher at Hospital del Mar and CIBER for Obesity and Nutrition.
Impact of breakfast on overall health
The study, part of the PREDIMED-Plus trial, followed 383 adults aged 55-75 with metabolic syndrome, tracking their breakfast habits and health markers over three years. Researchers found that those who consumed too little (less than 20%) or too much (more than 30%) of their daily calories at breakfast had worse health outcomes than those who ate 20-30% of their daily calories in the morning. By the end of the study, the “Goldilocks” group showed healthier body mass, smaller waists, and better cholesterol levels compared to those with extreme breakfast habits.
The study found that quality was just as important as quantity when it came to breakfast. Participants who consumed low-quality breakfasts, regardless of size, showed similar negative health trends, such as increased waist measurements, poor blood fat profiles, and even decreased kidney function. Breakfast quality was assessed using the Meal Balance Index, which scores meals based on nine key nutritional components like protein, fats, fibre, potassium, calcium, and iron. This index also considers World Health Organization guidelines for added sugars, saturated fats, and sodium. Higher scores indicate better nutritional quality.
These findings, published in The Journal of Nutrition, Health and Aging, are especially important for older adults aiming to manage or prevent heart disease. While prior research has shown that eating breakfast is better than skipping it, this study highlights that it’s not enough to just eat anything—both portion size and nutritional quality need to be carefully considered. Interestingly, the study was part of a larger health intervention where participants followed a Mediterranean diet and focused on weight loss. Even within this generally healthy dietary framework, the composition of breakfast had a significant impact on health outcomes.
What is the ideal breakfast
The study recommends that an ideal breakfast should comprise 20-30% of your daily calorie intake, equating to 400-600 calories for a 2,000-calorie diet. The focus should be on balanced meals that include whole grains, lean proteins, healthy fats, and fruits or vegetables while avoiding processed foods high in added sugars and unhealthy fats. With the rising challenges of metabolic syndrome and cardiovascular disease, optimizing breakfast can play a vital role in managing and preventing these health conditions.
As nutrition science evolves, it’s becoming increasingly clear that when we eat may be just as important as what we eat. This study highlights that starting our day with the right amount of high-quality nutrition could be a key to better metabolic health. Álvaro Hernáez, researcher at the Hospital del Mar Research Institute, CIBER for Cardiovascular Diseases, and professor at Ramon Llull University, suggests that the old saying about breakfast being the most important meal of the day needs an update. “What and how you eat it matters,” he says, emphasising that controlled portion sizes and nutritional quality are crucial for improving cardiovascular health.
