One thing I’d prefer to discuss is that fat reduction plan fast can be achieved by the appropriate diet and exercise. An individual’s size not only affects appearance, but also the overall quality of life. Self-esteem, melancholy, health risks, as well as physical skills are afflicted in extra weight. It is possible to make everything right but still gain. If this happens, a medical problem may be the root cause. While an excessive amount of food and never enough exercising are usually at fault, common health conditions and traditionally used prescriptions could greatly help to increase size. Thanks alot : ) for your post right here.

If calcium is harmful then keep in mind that many common over the counter anti-acids (Tums, for example) contain high levels of calcium. I have been a heavy life time user of anti-acids. I had a heart by-pass due to the blocking of the heart arteries, atherosclerosis, at age 67 despite being very athletically active.

What I don’t see from this study is the type of supplements taken. There are many types of Calcium supplements, some with Vitamin D, and some without. The researchers need to break down the study further to determine all the variables. Also, at what age did these heart attacks occur? Like all studies, we find out with further research that the original will be refined and the results altered. Just think about all the studies that told us which foods were bad for us, and now are okay. Examples; butter, eggs, coffee, chocolate to name a few! These studies kinda sound like another episode of Woody Allen’s “Sleeper” movie if you can remember back that far!

They listen to all the advice and follow all of ways up to them to achieve this. Some of these may be proper ways, and some may improper. Eventually, they lose some weight, then gain more weight.

Excessive intake of calcium causes heart diseases because calcium starts blocking the arteries and veins of men causes blood circulation. It may cause heart attack, heart valve not functioning properly etc. In these all cases, personal training will help you out to maintain your nutrient diet so that you will never have any problem in dietary plans.

You lead us to believe that calcium supplements may not be heart friendly, but as an alternative you suggest foods that are fortified with calcium. Isn’t this just another form of a supplement?

Calcium and phosphorous are used by the body to negate acidity which occurs when we eat animal protein (meat, fish, dairy). When you stop eating animal protein and consume more whole plants, then your need for calcium and phosphorous drops and the supply increases. Sufficient vitamin D is easily obtained from spending 10 to 15 mins every 2 or 3 days in sunlight without sunscreen (make sure you do not burn). The body is in balance again without the need for supplements.

There is no mention of Vitamin D supplements in this article. There has been considerable documentation that Vitamin D supplements aids in the absorption of foods having high content of calcium i.e. Dairy products, cereals etc.. Is Vitamin D still considered a valuable supplement.

I am skeptical about this studies, since they don’t inform about how calcium affects heart health. Hearth disease has many manifestations and we are left on the blank about how calcium can help to develop any of them. Does it have an effect on blood pressure, and how? Cholesterol maybe? Atherosclerosis? What kind of calcium supplements are they talking about? Even more important, would the study subjects have developed hearth disease due to diet and life style even if they had not taken any calcium supplements? Without this info, it is difficult to make up your mind about this supplement.

According to some articles in other web sites, Americans in general with the big comsumption of red meat, need to take more calcium to restore what is spent during digestion of the meat. The calcium needed by digestion is obtained from the bones.
