Research indicates that it might be beneficial to shift that evening glass of milk to breakfast time. A new study involving over 36,000 American adults indicates that high levels of calcium consumption in evening meals might be associated with an increased risk of cardiovascular diseases. The concept that consuming calcium-rich foods during dinner could contribute to heart disease is complex, involving a close analysis of diet, cardiovascular health, and how calcium is processed in the body.
Calcium, a critical mineral, is essential for maintaining muscle functionality, healthy bones, blood clotting, and nerve communication. Yet, the link between calcium intake and heart health remains controversial, with various studies yielding conflicting results. Calcium absorption varies based on age, gender, hormones, and diet. Incorporating calcium-rich items like dairy, greens, and fortified products helps fulfill daily calcium needs. Yet, excessive use of calcium supplements may surpass the body’s regulatory capacity, potentially harming cardiovascular health.
The research included more than 36,000 men and women, among whom 4,040 were diagnosed with cardiovascular diseases. Their calcium consumption in morning and evening meals was categorized into five groups. The study revealed that from a circadian rhythm standpoint, calcium absorption could be more efficient during daytime hours. This is because the hormones necessary for calcium metabolism are generally more prevalent when it's light outside.
Researchers concluded that distributing calcium consumption across breakfast and dinner optimally reduces the risk of cardiovascular disease. They discovered that maintaining a constant total calcium intake while shifting 5% of the evening's calcium to the morning was linked to a 6% decreased risk of cardiovascular disease.
The body's reaction to calcium suggests the need for smaller servings. Since vitamin D boosts calcium absorption, taking calcium in the morning could be advantageous, allowing for vitamin D exposure from sunlight throughout the day. Alternatively, splitting the calcium intake into smaller doses consumed with meals could be effective, as the body can only process a certain amount of calcium at once.
When e-cigarettes first appeared on the market, they were heavily promoted as a safer option for adult smokers trying to quit traditional tobacco. It soon became clear, however, that the nicotine-laden e-liquid used in vaping devices is highly addictive. The full mid- and long-term health effects of vaping are only now beginning to come into focus.
A recent study finds that people with major depressive disorder have brains that seem markedly older than their chronological age, connecting mental health with accelerated brain aging. While aging occurs naturally, mounting research suggests depression may speed up specific brain aging processes.
A groundbreaking new study has shed new light on how type 2 diabetes directly reshapes the human heart, impairing its energy production and structural integrity. These subtle yet profound alterations in the heart shed light on why individuals with type 2 diabetes face a dramatically elevated risk of developing heart failure.
