Abstract

It is generally accepted that a high-protein diet prevents the development of cerebrovascular lesions and improves the survival rate in studies using stroke-prone spontaneously hypertensive rats (SHRSP). Moreover, it is well documented that the preventive effect is largely due to attenuation of the development of severe hypertension. However, in addition to the reduction of blood pressure, there must be some other mechanisms which are nutritionally effective. In order to elucidate nutritionally effective mechanisms, we investigated the prophylactic effect of a protein diet (the K diet) on the development of cerebrovascular lesions in SHRSP. The diet was composed of dried bonito protein as the protein source and contained the same amount of protein as the control diet (the Funabashi SP diet). Experimental groups were maintained on the K diet from 5 (ca. 130 mmHg), 8 (ca. 200 mmHg) or 10 (ca. 230 mmHg) weeks of age and the control group was maintained on the Funabashi SP diet, with free access to the diet and to drinking water. In the experimental groups administered the K diet from 5 or 8 weeks of age, the development of hypertension was attenuated, there was a reduction of the incidence of cerebrovascular lesions and elongation...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
