Cardiovascular health

Section reviewed by cardiologist Astghik Grigoryan

When comparing Mars and Snickers bars in terms of cardiovascular health, both are similar in terms of their nutritional profiles. They are both high in sugar, saturated fat, and calories, which are not favorable for cardiovascular health when consumed in excess (1).

If consumed regularly, the saturated fat content in these bars can raise LDL (“bad” cholesterol) levels in the blood, which is associated with an increased risk of atherosclerosis.

In terms of specific differences, Snickers bars contain peanuts and caramel, which may provide a slightly higher amount of protein and fiber compared to Mars bars. However, these nutritional differences are minimal and do not significantly impact their overall cardiovascular health.

For a heart-healthy diet, it's best to limit the consumption of candy bars like Mars and Snickers and opt for healthier snacks such as fresh fruit, nuts, or yogurt. If you're craving something sweet, consider indulging in a small portion of dark chocolate, which contains antioxidants and may have some heart-healthy benefits when consumed in moderation.

Diabetes

Diabetes and metabolic disorders are some of the main reasons for high mortality among populations. High caloric intake, high amounts of saturated fats, and refined sugars are the main reasons to increase risks of developing type 2 diabetes and metabolic syndrome (2). Mars bar and Snickers bar fit the category of high saturated fat and high sugar foods.

Cancer

Mars and Snickers contain high amounts of sugars which are directly indicative of increased risks of cancer. The increased risk of cancer development is between 23% and 200%, which is highly significant (3).

Guidelines

Overall, guidelines indicate that to maintain good cardiovascular health regarding diet restrictions and control, there has to be a reduction of saturated fat and reduced intake of refined sugars. The saturated fat intake shouldn't surpass 10% of the total caloric intake (4).
