Diet… such a simple word, yet a powerful one; as a verb, to diet, for many, conjures up starving oneself of any and all pleasurable foods and drink. For others, it is a complicated system of assigning points and measures to every bite taken. Regardless of the format, most people diet with the intent to lose weight. More recently, however, the “noun” version of the word has taken on more importance in our society than ever before. Sure, as children we learned about the four basic food groups and the food pyramid, but beyond that, we ate what we wanted and didn’t question much the consequences. Through advancements in technology our society has started moving at a much faster pace than ever before. A seemingly endless supply of fast, easy food became available, satisfying our need for immediate gratification. Decades of fast food, snacks, sodas, sweets, etc… have caught up with us however, and the results aren’t looking so good. As a matter of fact, they are proving to be quite harmful to our quality of life and even deadly. Some of the most common diseases and ailments in America, including Alzheimer’s, can be linked to a lifetime of poor eating habits and choices. Medical News Today (MNT) lists the top 10 causes of death in the US as:
- Heart disease
- Chronic lower respiratory disease
- Alzheimer’s disease
- Influenza and pneumonia
- Kidney disease
As you can see, over half of these relate to diet or at the least, being overweight in general. For some, the thought of Alzheimer’s disease being related to diet may seem strange. However, as more studies are showing, overall health and diet play a huge part in how the body functions, including the brain. For years, we have understood the relationship between diet and heart disease. More recently, similar links are being discovered between diet and Alzheimer’s. The brain depends on a healthy blood flow to stay strong and maintain brain cell population. Therefore, a healthy brain depends on a healthy heart to supply it with blood. In addition, researchers are finding evidence that the same risk factors that lead to heart disease may also lead to Alzheimer’s.
Some examples include:
- Lack of exercise
- High blood pressure
- High blood cholesterol
- Elevated homocysteine levels
- Poorly controlled diabetes
- A diet lacking in fruits and vegetables
They go on to state that,
“These risk factors are also linked to vascular dementia, a type of dementia caused by damaged blood vessels in the brain. Working with your health care team on a plan to control these factors will help protect your heart — and may also help reduce your risk of Alzheimer’s disease and vascular dementia.”
Using this information, experts have been conducting studies on modified “heart healthy” diets and the development of Alzheimer’s. Martha Clare Morris , ScD, a nutritional epidemiologist, along with some colleagues at Rush University Medical Center did a study using their recently developed the MIND diet, a combination of the popular Mediterranean and DASH diets and discovered that diet lowered the risk of developing Alzheimer’s by as much as 53%. The Mediterranean diet is considered an overall “heart healthy” diet, utilizing the ingredients and cooking techniques associated with its name sake, while DASH, (Dietary Approaches to Stop Hypertension) was specifically designed to lower blood pressure.
The MIND diet consists of 10 “brain healthy” food groups and 5 unhealthy groups:
green leafy vegetables red meats
other vegetables butter and stick margarine
berries pastries and sweets
beans fried or fast foods
“Everyone experiences decline with aging; and Alzheimer’s disease is now the sixth leading cause of death in the U.S., which accounts for 60 to 80 percent of dementia cases. Therefore, prevention of cognitive decline, the defining feature of dementia, is now more important than ever,” She continues by saying that, “Delaying dementia’s onset by just five years can reduce the cost and prevalence by nearly half.”
Though not mentioned, another benefit of delaying a possible onset is that a cure or preventative solution may be discovered in the meantime. Making relatively simple changes in our diets today can have very positive long term effects on our future. The truth is, on average, Americans are living longer than ever before, which means we need to do what we can to insure those extra years are quality ones. So, listen to your mother and eat your vegetables.
