Join me in discovering what happens to the body from a nutritional standpoint where things go haywire and affect the brain and most importantly how to fix them. You'll see where we stand now with a public health burden of neurological diseases.
We will weave our way through the history of nutrition research, learn some primers on nutrition and digestion, and then discuss how poor nutrition leads to disease in the body and the brain specifically. We'll then wrap up with a look at different diets that can help reverse this.
Brain disorders including developmental psychiatric and neurodegenerative diseases represent an enormous disease burden in terms of human suffering and economic cost. Many brain disorders are chronic and incurable conditions whose disabling effects may continue for years or even decades.
Thus the overall disease burden from these disorders is much greater than would be suggested by mortality figures alone.
Brain disorders emerged as leading contributors to global disease burden. Brain disorders involve both neurologic and mental health disorders.
In Europe, it's estimated that 35% of all disease burden is attributable to brain disorders. There are currently an estimated 322 million people affected by depression, mostly in Southeast Asia and the Americas, less so in the African and Middle Eastern regions.
Also, the incidence and prevalence of stroke worldwide has nearly doubled, and even though we are dying less from stroke,
we are living longer with disability from stroke. More than 140,000 people die every year from stroke in the United States.
It's the leading cause of serious long term disability. Each year, approximately 795,000 suffer a stroke. The risk of having a stroke more than doubles each decade after the age of 55.
Stroke death rates are higher for African Americans than for Caucasians, even at younger ages.
On average, someone in the United States has a stroke every 40 seconds. And in the latest statistics, strokes accounted for
about 1 of every 17 deaths in the United States. Another disease, Alzheimer's has also gone from an nonexistent condition in the 1970s to a current epidemic. Alzheimer's Disease International estimates in it's latest report that there were 35.6 million people with Alzheimer's disease worldwide in 2010. And that this will grow to 115.4 million people by 2050.
Now let's talk about the obesity epidemic. Also growing in numbers over the last few decades, 30% of the population in the US is considered obese. That is a body max index or BMI of more than 30. BMI is a measure of body fat based on height and weight that applies to adult men and women. Unfortunately, BMI appears to be strongly correlated with various metabolic and disease outcome as are other more direct measures of body fatness. BMI is not the sole indicator and doesn´t seem to be working on athletes but can act as an indication for the average person.
For example, the CDC shows how there is a clear co-relation between diabetes and obesity. From an evolutionary standpoint, we are doing worse now with the advent of readily available convenience food. Historically, this was limited to the US, but now in various degrees it's a global concern.
