Hi welcome to healthcaremagic.
I have gone through question.
Blopd pressure 140/90 is slightly higher than normal. To control bp and restrict
cholesterol without medicines follow these steps.
Avoid salty food, too much salt in diet, avoid pickle etc.
Avoid oily food, avoid junk food, avoid cheeze butter, fatty diet
Do regular exercise, walking.
Take plenty of fruits, green vegetables.
Avoid alcohol,
smoking.
These measures help in controlling bp and cholesterol.
If with these measures bp and cholesterol not in control then consult your family physician and should take medicines.
Hope i answered your question.
Would be happy to help you further.
Take care.
