Hi Lena, From me looking at everything, your dad, is Pre-Diabetic, High Blood Pressure, High Cholesterol, and Prostate cancer. Pre-Diabetic Intermittent fasting should be practiced at least 3 times a week of 18hrs Any type of CARBS or SIMPLE CARBS, should never be consumed during the day, it should all be moved to last meal of the day. Discontinue any seed oils or vegetable oils, or any canned and or processed foods. Keep it simple. Any fruits should be consumed with last meal ONLY Any Grains should be consumed with last meal ONLY High Blood Pressure You would need [Nitrate Supplement]( https://www.berkeleylife.com/register/?practitioner_code=MD2021) to stable and [Magnesium Chloride](https://ca.iherb.com/pr/trace-minerals-low-sodium-mega-mag-400-mg-4-fl-oz-118-ml/23262) to saturate your cells.
