In this part, we'll look at myths surrounding bad cholesterol, eggs, dairy products and sun-blocks.
Bad cholesterol is the cause of heart disease. The TRUTH: Like fats, cholesterol may be damaged by exposure to heat, oxygen and free radicals. Both good and bad cholesterol are not immune to such exposure. Free radicals are what's in the air and around food, that causes this oxidization; free radicals cause your freshly-cut apples to go brown (an obvious sign of oxidization). The free radicals make dairy products more "sticky" and tend to stick to the walls of arteries. This sticky stuff is known as 'plaque'. You can see the plaque stuck in diseased hearts from post mortem-ed bodies of heart attack victims (my uncle was one, he was just 41 when he passed away and he ate a lot of meat in his heydays).
The plaque found in diseased arteries and hearts can range from yellow to white - exactly the same colours of those found in cheese and milk (read more below!) The oxidization of cholesterol (fats) is what contributes to the pathological buildup of plaque in the arteries. It's not whether good or bad cholesterol; it's whether the fat is oxidized. |

Sure many people love the summer sun. The sun's rays make us feel good, and in the short term, make us look good. Sunlight helps our bodies create vitamin D. Of course, it's impossible to avoid the sun — who wants to hide indoors when it feels so great to get outside and be active? But our love affair isn't a two way street. Exposure to sun causes most of the wrinkles and age spots on our faces and is the number one cause of skin cancer.
In fact, sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers breakdown, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily -- taking longer to heal. So while sun damage to the skin may not be apparent when you're young, it will definitely show later in life.
