I am interested in a plant-based diet. Do you have any information on this?

I'm 48, and weigh 240 pounds. I'm on a weight-loss plan but I'm struggling with what is my best options for breakfast. I typically have low-fat yogurt with granola each morning — but think I should lay off the dairy. What's a good protein for me? Are eggs alone good enough? I don't have time each morning to make a meal.

My friend has stage 3 kidney disease. His doctor asked him to eat foods low in potassium. So far, we can’t find potassium in the nutrition information available on food labels. Is there anywhere he can get a list of foods low in potassium?

My doctor found that my blood levels of vitamin D were low. She gave me a prescription for 50,000 international units of vitamin D to be taken every two weeks. But I’ve read that the recommended dose is more like 1,000 IU a day, and that more than 4,000 IU a day is unsafe. I have thin bones but not osteoporosis yet. I’m a healthy woman and don’t want to do more harm than good. What’s your advice?

I am tired a lot, and have been tested for all the usual suspects. I eat fairly well, and get enough rest each night. My doctor told me I was “a little low” on B-12. Could this be the real cause of my fatigue?

I am a 52-year-old man with a family history of heart disease. My doctor says my blood pressure and cholesterol are great. My latest LDL cholesterol was 98 and my HDL was 45. I exercise regularly and I try hard to stick to a Mediterranean-type diet. Is there anything else I should do?

I have heel spurs. The pain is under control, but I worry about this getting worse. What causes heel spurs? Is it caused by ingesting too much calcium? How about a vitamin deficiency?

I have heard different opinions about whether too much sugar makes a child too active? What is the latest opinion? Does the sugar give them too much energy?

My daughter is 4’7”, and weighs 132 pounds. She also has high blood pressure and reflux. I’ve been trying to cut back on sugar drinks and fried food. Can you suggest any other changes to her eating plan to help?

My wife has numb feet and legs a lot. What causes this?
