Hi.. High cholesterol levels are one of the risk factors of stroke.. A mild to moderate high values are not significant to cause the stroke. However, if you do not include alterations in the lifestlyle in restricting the cholesterol consumption, the mild to moderate values are definitely going to be severe once and adding to the risk of stroke and heart conditions.. So its time to include modifications in the diet..
It is important that you check for the percentage of LDL cholesterols in the protein supplement that you take. HDL cholesterols are safe... So recheck the label....
Hope this message has helped you in providing the information that you wanted.. All the best...
