Eating calcium at this time can lower heart attack risk, study finds

A study, published in BMC Public Health this year has observed that eating calcium-rich foods at breakfast, instead of other meals, can lower the risk of heart attack.

Researchers found that substituting 5% of dietary calcium intake at dinner with the same intake at breakfast decreased the risk of heart attack by 6%, emphasising the importance of dietary calcium intake distribution across breakfast and dinner.

According to Dr RR Dutta, HOD, Internal Medicine,  Paras Hospital. Gurugram, “Distributing dietary calcium intake across breakfast and dinner is emphasised because timing plays a crucial role in its absorption and utilisation by the body. Calcium absorption is influenced by other dietary components and the body’s circadian rhythm. Consuming calcium-rich foods at breakfast and dinner ensures optimal absorption and utilisation throughout the day and night, supporting bone health and potentially reducing cardiovascular risk.”

Relationship between calcium intake and cardiovascular risk?

The relationship between dietary calcium intake and cardiovascular risk is multifaceted, according to Dr Dutta.

Adequate calcium intake is essential for maintaining healthy blood pressure levels, as calcium plays a role in vascular function and smooth muscle contraction.

“Additionally, calcium may help regulate cholesterol metabolism and reduce the formation of arterial plaques, thus lowering the risk of cardiovascular events such as heart attacks and strokes,” Dr Dutta said.

Should you adjust your dietary habits based on these findings?

Dr Dutta recommended incorporating calcium-rich foods such as dairy products, leafy greens, and fortified foods into both breakfast and dinner.

However, he advised that it’s important to ensure overall dietary balance and avoid excessive calcium intake, which may lead to adverse effects such as kidney stones or cardiovascular calcification.

Important considerations when adjusting calcium intake

Dr Dutta suggests, “Potential drawbacks or considerations include the need for individualised dietary plans based on factors such as age, gender, health status, and medication use. Moreover, calcium absorption can be influenced by factors such as vitamin D levels, medication interactions, and gastrointestinal health.”

He further added that consulting with a healthcare professional or registered dietitian is recommended before making significant changes to dietary calcium intake. Additionally, focusing solely on calcium intake may overshadow the importance of overall dietary patterns and lifestyle factors in cardiovascular health.

While incorporating calcium-rich foods into daily meals is crucial, it’s equally essential to maintain a balanced diet and consider individual factors such as age, health status, and medication use. By consulting healthcare professionals and adopting holistic lifestyle changes, individuals can take proactive steps toward enhancing cardiovascular wellness and enjoying a vibrant, heart-healthy life.
