We are often given mixed messages about which foods are bad for us. But you have to watch your diet. Have you ever spat your morning coffee after hearing the news about what kind of it increases the risk of cardiovascular disease? According to a recent Norwegian study, coffee from a coffee maker and a French press should be avoided because it raises cholesterol more than a beverage prepared in another way, especially with a filter. But wait. Have not scientists already concluded that coffee is good for you? You are not the only one who is confused. Today we are told that it is necessary to limit the consumption of eggs, since the yolk has a lot of cholesterol and the next day we hear that eggs can be consumed without restrictions. Health authorities say that saturated fats are the main cause of high cholesterol, and suddenly some scientists are starting to say that this is a very simplistic statement, if not completely false. “There are mixed messages to society about high cholesterol,” he agreed. Dermot Neely, who is the director of Heart UK, a national cholesterol charity. So what is the truth about cholesterol and what foods, if any, increase to the point where it can harm your health? What is cholesterol? It is a fatty substance that travels through the bloodstream to proteins called lipoproteins. We get some of our cholesterol from the food we eat, but most of it (about 80%) is produced in the liver. We need a certain amount of cholesterol for our body to function. For example, it is very important for cell building, the production of hormones and vitamin D. There are two main types of cholesterol. Low-density lipoprotein transports cholesterol to cells where it is needed. It is called “bad” cholesterol because when it is in excess, it sticks to the walls of the arteries, clogging them and therefore increases the risk of heart attack and stroke. High-density lipoproteins, on the other hand, are “good” at removing excess cholesterol from blood vessels and tissues, returning them to the liver. And the liver removes it from the body. Heart UK advises all adults to check their cholesterol levels by having a blood test. But there is no optimal level for which everyone should strive. For many, high-density lipoprotein and low-density lipoprotein are ideal, but cholesterol is not the only factor that determines the risk of heart attack or stroke. says there are many pieces in the puzzle. These are the triglycerides (another type of fat) in the blood, weight, age, diet, medical history and whether or not you smoke. Some people have such heredity that they are particularly prone to cholesterol damage. “If you have high cholesterol, it generally increases the risk of cardiovascular disease,” says Mellor. “But this is only part of the picture and other factors need to be considered.” “All the fats we consume in food are broken down and become a source of energy. However, foods with saturated fats that exceed our energy needs are more easily converted to cholesterol than unsaturated fats,” says Dr. “Reducing the intake of saturated fats and replacing them with unsaturated fats reduces the risk of cardiovascular disease.” However, some scientists claim that not all saturated fats are the same. Some studies show that certain dairy products, such as cheese and yogurt, actually protect us from cardiovascular disease, rather than contribute to it. There is a theory that these foods contain fatty acids with an excessive number of carbon atoms in the molecule, which can not be used to produce “bad” cholesterol. One of the main sources of saturated fat in the British diet is baked goods. Pies, cookies, cakes, pastries, cookies. “They contain saturated fats,” says Dr. Mellor. “You have to be careful because it is not only fat, it is also processed carbohydrates, flour, sugar and salt.” These are highly processed foods and are quickly digested by the body, but there are a few nutrients that can reduce the damage. These foods, which many consider healthy, say, protein / energy bars, can also cause high cholesterol. “High-energy foods are high in sugar and fat, but low in fiber, vitamins and minerals. “It’s bad, especially if you eat them instead of a healthy and varied meal,” says Dr. Mellor. Advertised by many as a healthy alternative to butter, “It has twice the saturated fat content of lard and can be very high in cholesterol,” says Dr. Neely. used less often, as an aromatic agent, not as an energy source. “Much depends on what you eat. and tofu (this soy product slightly lowers” bad “cholesterol) we are under pressure, we tend to eat unhealthy foods and this is fraught with weight gain. Another theory is that in response to stress, the body releases certain hormones that increase “bad” cholesterol. But there is good news. Exercise helps increase “good” cholesterol and reduce “bad” cholesterol New research also shows that “bad” cholesterol increases in menopausal women due to a decrease in the hormone estrogen. Hormone replacement therapy What about coffee? Recent studies show that diterpene, which is found in coffee, has one characteristic – it raises cholesterol. But this only happens when we drink coffee in large quantities. According to Dr. Mellor, there is no evidence that moderate coffee consumption increases the risk of cardiovascular disease. “In fact, studies show that coffee can reduce the risk of cardiovascular disease and type 2 diabetes.” In other words, we should not think about coffee, but the cakes and cookies with which we grab it.
