The diet containing white fish meal, euphausia, euphausia/white fish meal, yolk/egg white, chlorella/white fish meal, hydrocarbon yeast/white fish meal, sweet smelt or dried beef meal/meat bone meal as a protein source could markedly depress the elevation of blood pressure, prevent the incidence of stroke and elongate the life-span in SHRSP. We observed marked or slight enlargements of the kidney (1.6-2.0 times as heavy as the control) and the liver (1.1-1.2 times) in SHRSP fed with the 50% white fish meal diet or the 50% casein diet over a long time, but did not observe it in feeding with the diet containing under about 30% crude protein. Therefore, the 35% euphausia or 25% euphausia/10% white fish meal diet seems to be most effective in preventing stroke in SHRSP.The incidence of stroke in SHRSP was prevented by providing these diets from an early age-the earlier the better.The 50% dried beef meal diet was effective, but 25% dried beef meal/25% meat bone meal diet was more effective in males. It seems that not only protein but minerals play a role in the prevention of stroke.
