When it comes to heart health, people often point to salt as the main culprit. But sugar is equally a significant contributor to increasing the risk of heart issues. They both have different impacts on the body. Let us understand how they work can help you make better choices every day.

How Sugar Affects Heart Health?

Excessive sugar amounts are associated with weight gain, high blood pressure and inflammation. All these predispose one to heart disease. When you take sweet drinks, candy or packaged food, more insulin is produced by the body. This may eventually render the body resistant to insulin, straining the heart.

Triglycerides are also increased with high sugar levels. These are blood-circulating fats. Increased levels cause the hardening of the arteries. This increases the efforts of pumping the heart.

Research has demonstrated that individuals who use and consume excess sugar are prone to type 2 diabetes. One of the highly contributing risk factors of heart attack and stroke is diabetes. Although that individual may not be overweight, excessive intake of sugar can harm the blood vessels as well as put the person at risk of heart trouble.

How Salt Affects Heart Health?

Salt has sodium, which the body requires in low quantities. However, excess intake of sodium past the healthy ranges leads to retention of water in the body. This augments blood circulation in the vessels and elevates blood pressure. A continuous rise in blood pressure over time impairs the heart and predisposes one to the risk of heart failure and stroke.

The majority believe that salt is just what they change by adding it on food when cooking.However, packaged food products including chips, breads, instant noodles, breakfast cereal and canned sauces contain high levels of hidden sodium.Regular consumption of them may make one eat many times beyond the maximum sodium intake without even noticing it.

Sugar vs Salt: Which Is More Harmful for the Heart?

Both salt and sugar are damaging to the heart but in different ways. Sugar influences metabolic processes and fat levels, whereas salt influences blood pressure. Salt is more detrimental in the case of high blood pressure. In case you are having a weight problem or insulin resistance, sugar becomes more dangerous. A high-sugar diet is further detrimental to most individuals, as it simultaneously impacts a number of body systems.

The best option is to manage the two. A heart-friendly diet restricts chocolate beverages, packaged cereals and pastry products. It also restricts the consumption of salty foods and seasonings. Cooking and fresh fruits, vegetables, whole grains, nuts and home-cooked meals, along with keeping a good balance.
