You are urged to juice for a reason. I look back on just 2 experiences in my life and try to learn from them by what I saw. You should do likewise.
First was a smoker who came down with cancer. They bought carrots to juice, 50# at a time. Extended his life.
Second died shortly before the age of 50. He never ate veg even as a child. He was a true meat & potatoes guy. Once cancer raised its ugly head, there was no stopping it.

A basic, inexpensive recipe that is good for whatever ails you:
Carrot, ½ cucumber, 1-small beet, 2 –stalks of celery. Use enough carrots so the drink is ~16 oz. A small apple is allowed to sweeten if needed, otherwise DO NOT mix fruits with veg. Throw the pulp in the compost pile. Drink more juice.
