Question: watched a tv show on heart healthy diet and supplements ... can't remember the name of the DR!
am remembering RC was magnesium supplement (I don't eat XXXXXXX and don't like spinach!) ... not sure what form ... is magnesium oxide put out by naturemade safe and effective? And is the 400 or 250 mg bottle right? I'm 72 ... my heart is (reasonably) healthy ... I don't excersize enough but I'm able to get around ok. I do ride a bicycle.In general is there something I'm missing from the heart healthy dietary supplements? I eat pretty well ... mostly poultry and fish ... lots of veggies and fruits ... 1/3 glass wine with a meal ... dont drink or smoke ... I do eat bread .... remember the doc on tv said keep away from wheat and milk products ... but i do eat eggs and cheese .... occasionally beef and ham ... so what else is necessary to stave off all the ills of growing old except reasonable cardio excersize and social support? What other supplements have I missed out on?!

Brief Answer:
You doing exceptionally well...

Detailed Answer:

Apologies for the late reply. Well, before we continue to discuss about your question I wish to congratulate you for maintaining a healthy heart. Not many people at your age are able to ride a bicycle. If you are able to do that effortlessly, then in my opinion you will be able keep coronary heart disease away from the next 5-10 years.

As far as magnesium is concerned, it's one of mineral that we require in milligrams (macronutrient). It's principle use is on the bones. However it has key role to plan with regards to heart, muscular and bowel function. Currently magnesium is primarily used in large quantities while treating digestive issues - heart burn, constipation and bone disorder. I am not aware of any case report where magnesium was used in treating organic heart condition except when there is proven deficiency. Therefore presuming you don't have a deficient state, I don't feel you need extra magnesium. If you wish to take it, you may try 400mg a day.

Overall, your lifestyle seems pretty good. Avoid processed food products. Whole grain wheat is ok; milk product should be minimal to null - I am ok with occasional cheese, beef and ham unless you have history of high blood pressure and high cholesterol level. Make sure the fruits and vegetables are as fresh as possible. Also include beans, flaxseeds, nuts, almonds, broccolli, spinach, asparagus and so to prevent coronary heart disease.

Hope this answers your question. Let me know if you need clarifications.

Thank you for your answer and your clarity ... just a few clarifications?

Could you discuss the consumption of eggs?

I occasionally make an omelet using 1 whole egg and some of the "egg beater" 50% fat free mix in combination.

Then what should I cook with in the pan? Right now I have been using 50% fat-free butter substitute to cook in the pan, and also extra virgin olive oil ... any other suggestions for heart health? I read somewhere to minimize saturated fats.

I also read that wheat products (especially those that include gluton) are to be avoided for heart health ... right now the bread I use is an oatmeal mix that is 50% fat-free. So I'm a bit confused over your note that whole wheat products are OK? Is my bread OK also?

NOW in order to increase FIBER, what specific products should I eat? I thought about raisin XXXXXXX or cheerios cereal, but that would require milk, which you say to minimize … I guess a bit of 1% or 2% milk would be OK to go just with the cereal? I can’t really abide skim milk.

Thank you for your consideration.

Brief Answer:
Interested in knowing your weight and cholesterol.

Detailed Answer:

I am interested to know what your current weight is. Is it in lines with current body mass index standards (19 to 24)? I would also like to know about your serum cholesterol levels.

Currently there are plenty of fads on the topic of diet especially with regards to fats and gluten. Both these have good as well as bad effects on heart. Let me clarify.

1. Occasional whole egg is good. Egg yolk is a good source of vitamin D. You would be missing the vitamin D if you miss out on the yolk. However since it also contains plenty of fats especially the bad ones, it should come off the diet on most occasions. I said most occasions and not always.
2. If it's occasional the 50% fat free mix is good.
3. You can use extra virgin olive oils to cook this egg. I would prefer to avoid fat free butter if cooking pan is a non-stick one. Butter has plenty of saturated fats. Even the 50% fat free is loaded with saturated ones. It may be used once in a while, but I will prefer to avoid it every time I cook.
4. Gluten free diet is not an absolute necessity unless you are gluten sensitive. It has plenty of fibres which help in lowering cholesterol as well as improve bowel functions. Moreover wheat has other vitamins and minerals which you will miss. Therefore unless you are gluten intolerant, I don't see a harm in using it. No problem with having whole grain wheat bread. But avoid white bread that is made up of refined wheat.
5. I am ok with you taking milk. It is a good source of calcium that's important at the age of 75. What I am not ok is milk product such as butter and ghee. Skimmed milk is preferable.

Hope my answer is clear to you. Feel free to ask me questions if I am not clear.

I am a 47 year old diabetic lady, who had a Gastric Band fitted three years ago, and lost 6 stones. Before having this procedure, I had slightly raised cholesterol, but not high enough for medication. Over the last three years my Total Cholesterol level has gradually increased from 5.4 to now 7.1 My Bad cholestrol is very high, but my good cholesterol is VERY good, I don t have the exact figures. My Dr put me on Simvastatin approx three years ago. I took them willingly, and carried on my life as best I could, not realising how tiered and exhausted they made me feel with lots of aches and pains, I thought my problems where early menopause. Anyway last year after much research on the internet, I discovered that statins could give bad side affect in concentration and tiredness and muscle weakness, so I decided to address this with my Dr. Who instead of listening, gave me another tablet to take on top of the statins, because my cholesterol had started to rise again. (Sorry don t have the name of this one) I took these for a month, and they made me almost incapable of getting out of bed, the tiredness was so debilitating. I decided to stop taking them, and the Simvastatins. So I gradually weaned myself off of the drugs. I had decided not to tell the Dr, so I did it on my own. Anyway, when I went back to the Dr about something else a few months later, I told them what I had done, they strongly advised me to take another type of Statin. This time Atrovastatin 10mg was to be taken. I said I would but if they made me feel bad, I would stop them straight away. I took them for 10 days and started to get all the same side effects so just stopped, and the Dr could not persuade me to re take them. Then this year I have had a cholesterol test, and I am now showing a total of 7.1 When they told me how high it was, I said I didn’t care, because Id rather die tomorrow, than spend any more time taking these drugs. Anyhow they persuaded me to have one more try, and have given me Fluvastatin 20mg. That was nearly a month ago, and I haven’t talked myself into starting to take them yet, but would just like some general advice about High Cholesterol. Does high cholesterol mean that I’m going to have a heart attack or does it just mean I might? I do have heart problems in my family, my mother died at 48 of a massive stroke, but she was very over weight, and my father has just been prescribed Simvastins, for his high cholesterol, and he like me now, is a very slight man, he is 74 years old, and has developed Altzimers. He has also started to complain about tiredness and weakness ( possibly the same side effects as me). He does not eat a lot of high fat foods, and often forgetting to eat at all unless it is put infront of him. Can cholesterol really be inherited? What can I do? I live in the Mediterranean most of the time, so I feel my life style is very healthy. I eat plenty of fruit and veg, I drink moderately and do not smoke. We cant get takeaway food here, so nearly everything is prepared from scratch. My only vice is butter, and that is only when I m worrying about all this. Is there any alternatives to Statins, I did read something about a dialysis machine for cholesterol? But that was a long time ago, and was in the early stage of development. Should I try these next ones, or just forget it and see what happens. I like my life now, When I was on the Simvastatins, I felt I had no life at all, almost like I was taking part in someone else s life, not quite mine. I don t want to go back to feeling like that. Please help....
