Doctor that time said my BP high, I asked her need to take medicine? She said can monitor for a week first, told me to stop eating outside food and cook at home.
I have some nutrition knowledge, so I cook home food and measure the sodium I add when cooking the food, like soy sauce, salt msg, then I eat like 400-600g of fruits and veg a day ( I also measure with a weighing scale). Within a few days, my BP becomes 80/120 or below using a Japanese made Omron machine to measure.
My food taste a little like hospital menu though.
