Heart Health & Aging-Dr William Li
Sixty thousand miles long. That’s the length of the tube system inside us that transports blood, oxygen, and nutrients to the cells throughout our bodies.
If these tubes fail, the result can be fatal. In some cases, it’s a heart attack. In others, it’s a stroke, when the blood supply to the brain is disrupted and brain cells are damaged or killed.
Heart attacks and strokes are a major cause of death in developed countries — but we can take action to reduce the risks.
In this episode, Jonathan talks with a world-renowned physician, scientist, and speaker to gain insights into how looking after this magical pipework could slow aging.
Dr. William Li is a world-leading specialist in blood vessels and preventative health, and the author of countless papers on the topic. He possesses the gift for communicating about this complex subject in terms we can all understand.

How do carbohydrates impact your health?-Richard J. Wood
When we eat carbohydrates, they are broken down into glucose which is absorbed into our bloodstream. On detecting glucose, the pancreas releases a hormone called insulin. Insulin tells our cells to open and let glucose in so that it can be used as energy. However, consuming excessive amounts of carbohydrates causes the blood glucose level to spike, thus triggering pancreas to release more insulin. If this continues over a period of time, the cells stop responding to insulin. As a result, glucose begins to buildup in our bloodstream, thus leading to various health related diseases.
Now, glycemic index is a measure that ranks carbohydrate-containing foods according to their effect on blood glucose levels. Foods low on glycemic index are broken down slowly. Hence, the blood glucose level remains stable, thus lowering the risk of diabetes, aiding in weight loss, etc. Examples of such foods include cashews, apples, lentils, etc.
