Throughout the entire book Moalem tries to explain as to why certain damaging, heritable diseases still exist even though, as they are damaging to modern population, logically should be selected against during evolution. He argues that we need disease: so many diseases are still around today because at some point in history, each was beneficial to the survival success of our ancestors in their environment. Moalem includes an introduction in which he describes how and why he became interested in the medical sciences: it was a combination of both natural curiosities that he has had since childhood and the prevalence of genetic disease in his family that he was visible to when younger. The introduction also serves as a way for Moalem to easily express his true love for both science and discovering the mysteries to life and
Before getting into the takeaways from the book we need some definitions and to shed some perspective on how dire the diabetes problem is. So, what is diabetes? The short answer is it’s when your blood glucose or sugar is too high. How it works is when you eat food your body breaks it down into sugars that enter your bloodstream to be distributed throughout your body for energy, when this happens your pancreas releases a hormone called insulin to transport those sugars to the
Diabetes is a metabolic disease where the person has high blood sugar. This is either because the body does not produce insulin properly, the cells do not respond to the insulin, or both. There are three types of diabetes. Type 1 Diabetes is where the body does not produce insulin.
The causes of diabetes vary, but the most important risk factors: unhealthy diet, obesity and physical inactivity (2). World health organization (WHO) concluded that risk factors are associated with chronic diseases; hence are the challenges of the century of
A person had a 50/50 chance of dying from Ebola. Though the worst disease in history is the Black Death. Even though the Black Death was considered the worst disease in history, good things came out of it, for instance, doctors had come up with many remedies to combat the disease and ways to prevent from getting it, and the aftermath of the Black Death gave benefits to women and peasants. Around
Survival of the Sickest is an intriguing novel that explores why we need disease. Moalem asks and answers many questions throughout this book centering on the concept of evolution. His main objective in this book was to explain why natural selection designated certain diseases that are harmful to humans now. Throughout his questioning, he shows us that the reason so many diseases are still around today is because at some point in history, all of them helped our ancestors to survive and reproduce in their environment. Each chapter in his book focuses on a different aspect of his overall conclusion that modern diseases were beneficial in the past.
Insulin is a hormone needed in order for the body to break down glucose, a sugar used for energy. Without the presence of insulin in the body, sugar builds up in the blood instead of being broken down for energy, leading to harmful symptoms and long-term damaging
Survival of the Sickest, by Dr. Sharon Moalem, is a book that reveals the origins of some modern diseases that beset us today. It explains how these sicknesses have been passed on for so many generations, and the impacts they have had on humanity, thus shedding a new light on them. By reading this book, much can be learned from the many different infections the author wrote about. However, hemochromatosis, diabetes, and progeria most exemplify how such terrible diseases worldwide could have provided evolutionary advantages for our ancestors. Hemochromatosis, an inherited disease, is a condition in which the body produces excess iron thinking there isn’t enough iron in the intestines, even though there is.
Carbohydrates include a little bit of sugar with your body is just for energy and nutrients to maintain a good health. There are many ways to treat Type 2 diabetes. One is that you have to eat a lot of healthy foods. So that means you could only have fast food once in awhile. According to Mayo Clinic You have to take your insulin pen after you eat a meal or snack.
One of the concluding sentences that Dr. Sharon Moalem directs toward her audience is, “[...] Our relationship with disease is often much more complex than we may have previously realized.” “Survival of the Sickest” delves into the theme of the way inheritance and genetic codes in our bloodlines allows fatal diseases to enter our body and the reasons for this happening. The author discusses various diseases and their origin, and includes facts as to how this disease is able to affect modern life. She suggests that said modern diseases played a necessary part in the survival and selection of those before us in our history.
Diabetes is three times more common than 20 years ago. Mortality, even with the increase in incidence and prevalence the mortality rates have remained reasonably unchanged. Diabetes is the 8th leading specific cause of death for both males and females accounting for 1,923 deaths or 2.7% of all deaths in males, and 1,887, or 2.8%of deaths in females. Diabetes is also a contributing cause of death in about 10% of all deaths for both males and females. The trends in death rates of diabetes as the underlying cause increased from 15.8 to 16.5 per 100,000 between 1980 and 2007.

Illnesses such as the Plague (Black Death), Smallpox, measles, in the 16th century which people would not know how to cure those illnesses because they didn 't know what it was. These days people eat a healthier diet, so they don’t typically suffer from malnutrition as widespread as back in the 16th century. People still eat bad food and make bad selections but the research and knowledge about food has help us make better selections. Although people still believe that God gives them illnesses they now they go to a doctor and find help with symptoms and possible cure.
