Could there actually be a diet that can prevent
degenerative diseases of the brain, such as Alzheimer’s disease? There actually is and it’s called the MIND
diet or the Mediterranean-DASH diet, which is a combination of the
Mediterranean and DASH diets. The idea is that, when eating this kind of diet,
you can protect the brain cells from dying and decrease the incidence of
Alzheimer’s dementia.
The idea behind the MIND diet is that you eat from the
following food groups: vegetables, especially leafy green vegetables, berries,
nuts, whole grains, beans, poultry, fish, wine, and olive oil. The foods you
stay strictly away from include butter, cheeses, stick margarine, red meat,
fried food, fast foods, sweets, and pastries.
This diet was first developed in 2015 by a nutritional
epidemiologist at the Rush University Medical Center, Martha Clare Morris. She
worked with a team of researchers to follow the food eaten by 923 elderly
people over the age of 65 years old. They looked at these people’s diets for 4
½ years and found that 144 of the people in the study developed Alzheimer’s
disease.
Those participants who followed the MIND diet had a
decreased risk of developing Alzheimer’s disease. Even those people who changed
their diet moderately to approximate the MIND diet had a decrease in the
chances of developing Alzheimer’s disease.
They found that the risk for Alzheimer’s disease
dropped by 35% in those people who moderately followed the diet and dropped by
53% in those who strictly adhered to the diet.
Other
Studies
This wasn’t the only study to show that diet was
related to brain performance. One study found that those who ate at least two helpings
of vegetables per day, especially green leafy vegetables had better performance
on mental tests. Studies on animals showed that those animals who ate berries
performed better on memory testing. Large studies on people showed that eating
just one meal of fish per week decreased the risk of Alzheimer’s dementia.
The MIND diet stands for Mediterranean-DASH
Intervention for Neurodegenerative Delay. The researchers who developed the
diet based it on the DASH diet, which is usually used in those with high blood
pressure and the Mediterranean Diet, which is usually used to prevent heart
disease.
The original paper outlining the diet published their
research findings in the medical journal, Alzheimer’s
and Dementia: The Journal of the Alzheimer’s Association.
What the
Mind Diet Looks Like
In the MIND Diet, you need to concentrate on eating
these types of foods as part of a healthy diet:
·
At least one serving of vegetables
per day
·
Green leafy vegetables, at least
six servings a week
·
Nuts, especially tree nuts, like
almonds and walnuts
·
Whole grains, such as brown rice
and whole grain breads
·
Beans, such as kidney beans, pinto
beans, and black beans
·
Berries, such as blueberries,
strawberries, and blackberries, which are high in antioxidants
·
Wine, particularly red wine, which
is high in resveratrol
·
Olive oil, which can be used in
cooking foods or as a dressing
·
Poultry, such as turkey or Chicken
·
Fish, especially those cold-water
fish that are high in omega 3 fatty acids.
The foods
you stay away from include the following:
·
Red meat, such as comes from beef
and perhaps from pork
·
Cheese, of which there are many
kinds to avoid
·
Butter and stick margarine, which
are high in saturated fats
·
Fast food or fried food, which is
high in saturated fats
·
Pastries and sweets, including
candy and doughnuts
Every day, you need to eat at least one green leafy
salad, three servings of whole grains, and at least one vegetable (raw or
cooked). You need to have just one glass of wine with one of your meals. Snacking
is allowed as long as you stick to the diet.
Nuts make for good snacks on this type of diet. Beans
are eating every other day and fish is eaten once a week. Berries and poultry
are eaten about twice per week. Any of the foods considered unhealthy should be
eaten at less than one time per week.
The use of berries is particularly important on this
MIND diet. Blueberries especially ae packed in antioxidants, which help protect
the brain.
Strawberries are also potent and contain large amounts
of antioxidants. It seems that if you stick to the diet at least moderately and
eat most of the foods on the diet, your risk of developing Alzheimer’s disease
decreases significantly.
