As the name itself suggests, a “low cholesterol diet” will concentrate on limiting, or eliminating foods that are have a high cholesterol content and replacing them with food that has either lower, or no, cholesterol.
It is well known that there are certain foods that naturally have much higher cholesterol content than most others and it is a relatively simple matter to limit how big a part they play in your diet, or even avoid them altogether.
The “Big 6” foods that are naturally high in cholesterol and should be limited if you are working on reducing your cholesterol are: Meats from organs (brains, liver, etc.)
Egg Yolks (but egg whites are fine)
Whole milk (use 2%, or low fat)
While it is true that avoiding these foods will reduce cholesterol intake, it really isn’t a very good idea to completely eliminate any of the foods listed above. Besides having high levels of cholesterol, these foods also contain vital proteins, minerals, and vitamins our bodies absolutely require to maintain proper basic functioning.
Plus the body does require some cholesterol as well. It is a fundamental building block of the cell membranes and is also a vital source of energy. So, before beginning a diet primarily made up of cholesterol lowering foods you will need to plan on how to replace not only the lost nutrients but also make up for the lost energy source as well.
There is a very high degree of complexity in the way the fluid systems within our bodies function. This holds true, as well, for the circulatory system. Because the circulatory system is complex, there are many different blood pressure causes which are possible. Our heart rate and the thickness of our blood are just two of the many different factors which can affect the pressure of blood circulating within our body. There are many influences outside of our bodies which affect our blood pressure. Some examples of these factors are exercise, diet, drug or alcohol use, pre-existing disease and many others. In fact, there are many more outside influences which affect blood pressure as compared to the influences within our body.
First of all, let’s look at the most important element which is responsible for high or low blood pressure causes. The heart rate, or more specifically, the number of times our heart beats per minute is one of the biggest features related to our blood pressure. For the average healthy adult, a heart rate somewhere in the range of between 60 to 75 beats per minute would be considered normal. As our heart rate increases, so too does our pressure. Now another important element which has an influence on our pressure is the total volume of blood within our body. When the volume of blood increases, the volume of blood returning to the heart via our circulatory system also increases. This in turn, drives up our pressure. There is also a very direct relationship between our blood volume and our salt intake. As we increase salt intake, our blood volume and therefore blood pressure will rise due to a biochemical reaction known as osmosis.
