Excessive sugar intake can lead to various heart health issues. Diets high in sugar, particularly added sugars, can contribute to obesity, high blood pressure, and increased levels of triglycerides in the blood. These factors are significant risk contributors to developing heart disease. Moreover, high sugar consumption can lead to insulin resistance, increasing the risk of type 2 diabetes, which is closely linked to heart health. The NHS advises reducing sugar intake by opting for whole foods and being mindful of hidden sugars in processed foods. Making these changes can significantly benefit your heart health.
