Q. I have some mild plaque in my carotid arteries. Is it allright to use nuts and seeds for heart health?
It is a wise choice to stop the use of coconut milk and yogurt. I would encourage you to consider eliminating the olive oil altogether and recheck your carotid health in a year for a comparison study. Coronary artery disease can be arrested and reversed on a diet which entirely eliminates refined and unrefined fat sources (See this study).
If you are keeping your total nut and/or seed intake to 1 ounce (2 tablespoons) per day, this would be in harmony with the literature available. I would be eager to see your carotid results one year later after these changes.
