The heart is one of the vital organs of our organism. Charged with pumping blood to ensure the arrival of oxygen and various nutrients in all the cells of the body, ensuring its proper functioning is paramount to benefit from good health. Now, it is enough of some bad habits adopted in the long term to impact it. So discover the worst thing we do everyday and that alters the health of our heart.
One of the first factors that influences our health and particularly our cardiovascular system is our diet. Indeed, one of the most harmful foods that we consume daily, and at doses more or less high according to people, is sugar. These white crystals that give a sweet and sweet flavor to our cakes and drinks are not as harmless as they are in the air.
Why is sugar bad for your heart's health?
For a long time, fat and salt were the main symptoms of the poor health of our cardiovascular system. A new study by Dr. James J. DiNicolantonio, a researcher in cardiovascular medicine at the St. Luke's Mid America Heart Institute, found that 15% of the US population has more than a quarter of the calorie intake from added sugars. This is a threefold increase in the risk of death from cardiovascular disease.
Indeed, this overconsumption of sugars is due to the abundant presence of sugars added in the various dishes and drinks that are now part of our daily diet and which considerably increase the risks of the appearance of several diseases such as hyperlipidemia, diabetes Type 2 and hypertension, all of which threaten the health of our cardiovascular system.
To better understand the correlation between refined sugar and cardiovascular disease, let's take a closer look at how it affects our body.
Sugar and hyperlipidemia
Hyperlipidemia consists of having a high lipid level in the blood, including cholesterol and triglycerides. The latter are mainly due to excessive consumption of rapid sugar and alcohol. A study conducted in 2010 of nearly 6,000 people clearly showed that excessive sugar intake led to an increase in the level of bad cholesterol in the blood and to a drop in good cholesterol. The accumulation of lipids in the blood leads to a deposit of fats on the walls of the arteries of the heart, thus causing their thickening or the formation of blood clots and increases the risk of obstruction of certain less large blood vessels leading to Such as a heart attack or stroke.
Sugar and Type 2 Diabetes
By consuming sugar, the pancreas produces insulin in order to allow the absorption of the latter by the different cells of the body which will use it as fuel. But by consuming too much, the cells develop resistance to this hormone and no longer respond to its signaling, causing an increase in the level of sugar in the blood. This results in a continuous stimulation of the pancreas, which in the long run leads to its exhaustion. The result is type 2 diabetes, which in 2 to 3 times the risk of cardiovascular mortality in men and 4 to 5 times in women.
By impacting fat metabolism, type 2 diabetes promotes the deposition of fats in the arteries and blood vessels and thus leads to many important complications such as renal insufficiency, arteritis of the lower limbs, visual alterations As well as a major risk of myocardial infarction and stroke.
Sugar and hypertension
According to a study published by the British Medical Journal, added sugar would have a more aggravating effect on the risk of hypertension and cardiovascular disease than salt. Indeed, consuming more than 74 g of fructose per day is linked to a 30% increase in blood pressure above the standard of 140/90 mm Hg, and a 77% increase in blood pressure that Reached the 160 / 100mm Hg.
In case of hypertension, the pressure exerted by the blood on the walls of the blood vessels and too high, even at rest. In the long run, this pressure weakens the latter and can lead to atherosclerosis, or to exhaustion of the heart muscle. This will result in a higher risk of myocardial infarction, cardiac depletion and stroke.
According to the World Health Organization, the contribution of sugar to our daily caloric intake should not exceed 10%, with an ideal percentage of only 5%. Remember to replace it with stevia or organic honey, and to limit the consumption of processed foods and soft drinks as much as possible
