Fat generally contains high levels of cholesterol. Intake of excessive cholesterol will easily lead to arteriosclerosis and induce the heart and brain vascular diseases.

In recent years, Japanese experts found that the farmers who do not intake much cholesterol hold a higher rate of the occurrence of stroke than the urban population who intake relatively more cholesterol. This phenomenon was studied by experts, and they have found that it is possibly related with the malnutrition of the smooth muscle cells on the cerebral vascular walls. And an appropriate amount of intake of cholesterol can effectively improve the malnutrition condition of the smooth muscles of vascular walls.

Therefore, our correct attitude to the fat should be neither unscrupulous nor frightened. The overweight people and those who are suffering from coronary heart disease should control the intake of the food that includes high cholesterol. Normal people, particularly those who are middle-aged and old should go on a diet of balanced nutrition which mix animal meats and vegetables, especially for fish food, because there isrich taurine and amino acid in the protein of fish flesh that can lower the blood pressure and remove the excessive cholesterol in the body to a degree, so that it can help prevent the occurrence of strokes.
