Nutrition experts know that the best food group for preventing and fighting cancer are the cruciferous vegetables or cabbage family vegetables. They include cabbage, cauliflower, broccoli, brussels sprouts, kale, collard greens and others. Cancer is the second leading cause of death of Americans. But here is the latest news that I, Chuck Bluestein, just discovered in May 2009, the same time that Microsoft came out with Windows 7. The best food group for helping with cardiovascular problems is berries.
Who says so? I do. Why do I say this? That is what this article is about. If I am wrong, then you can have fun finding the holes in my theory. The botanical definition of a berry is a simple fruit produced from a single ovary, such as a grape or a tomato. However, in everyday English, a berry is a term for any small edible fruit. So I will go by the everyday English meaning. Heart attacks and strokes are the first and third leading cause of death of Americans.
Even though we are not using the first definition, grapes have the phytochemical resveratrol in them. Tomatoes have the phytochemical lycopene in them. Both are good for cardiovascular health and for cancer protection. The first thing is the Doctrine of Signatures. This states that an herb, botanical or plant food sometimes gives a clue about what it is good for by its appearance like ginseng root looking like a human body or a walnut looking like a brain.
Berries are the color of blood. Blood that is very oxygenated is red, but blood without oxygen can appear blueish or purple. Just look at the veins of someone with varicose veins. Lycopene is the phytochemicial in many foods that make them red. One newer red berry that is great for cardiovascular health is goji berries. Here is what webmd.com says about goji berries:
"Research shows that eating berries -- like blueberries, acai berries, cranberries, strawberries, and cherries -- offers some definite health benefits. Berries like the goji berry are filled with powerful antioxidants and other compounds that may help prevent cancer and other illnesses, including heart disease."
Strawberries are said to help lower high blood pressure (hypertension) See study done by clicking on the following link. Another good example of the Doctrine of Signatures is the strawberry. It is red and is shaped like a heart. Note that berries have different anthocyans (a group of phytochemicals) that strengthens the inner lining of the arteries. Common problems with arteries include angina, congestive heart failure, intermittent claudication, peripheral arterial disease (PAD), strokes and heart attacks. The above website says:
"A recent study
conducted at the Harvard School of Public Health
found that participants eating the most strawberries had the lowest blood levels
of C-reactive protein, a marker for inflammation in the blood vessels, and
slightly lower cholesterol levels than those who consumed fewer strawberries.
Another study found that strawberry eaters have lower blood pressure than
non-strawberry eaters. Further, strawberries are a good source of potassium,
which helps regulate electrolytes in the body, lowering the risk of heart attack
and stroke. Strawberries' folate, fiber, and vitamin C also provide
heart-protective benefits."
Superfoods Rx (2008) by Steven Pratt, M.D.
says (p 28) "The anthocyans also work synergistically with vitamin C and
other key antioxidants. They strengthen the capillary (tiny blood vessel) system
by promoting the production of quality collagen-- the building block of tissues.
This important subclass of flavonoids also promotes vasodilation (widening of
arteries) and has an inhibitory effect on platelet aggregation-- an aspirin-like
effect on blood clot formation." Please note that aspirin are drugs and
berries are foods.
If you look these things up, you will see that
they are also effective for preventing cancer. A recent study from the
University of Michigan reveals that new evidence links cherries (a red berry) to
heart health benefits. The study found that a cherry enriched diet lowered total
weight, body fat (especially the important belly fat), inflammation and
cholesterol-- all risk factors associated with heart disease. According to the
American Heart Association, being overweight or obese, in particular when the
weight is concentrated in the middle, is a major risk factor for heart disease.
There
are other red berries like cranberries and then there are the other darker color
berries. Some that have attracted a lot of attention for health benefits are
acai berries, yumberries and aronia
berries that are said to improve circulation and strengthen blood vessels.
Here is what the above website says about acai berries "Studies show that
anthocyanins can help prevent blood clots, improve blood circulation, relax
blood vessels, and prevent arthrosclerosis."
If you are
acting too immature, then you can take elderberries to help you act older, like your elders. Actually elderberry juice is known to lower cholesterol levels and reduce bad cholesterol. This can be highly beneficial in preventing the various heart related disorders. Bilberries
are great for night vision. There is a red berry that is great for cardiovascular
health. But I have not seen it sold as a berry. I have only seen it sold in
capsules or as a tea. Herbalists know that it is the best herb for heart health
or cardiovascular health. It is the red hawthorn berry.
Prescription
for Herbal Health (2002) by Phyllis Balch says "
A large body of
scientific research has shown that the fruit, leaves and flowers of various
hawthorn species dilate the blood vessels, lower blood pressure and dissolve
cholesterol. Hawthorn fights atherosclerosis, in which cholesterol forms plaques
on blood-vessel walls. in two ways." It increases the rate that the liver
converts bad LDL cholesterol into good HDL cholesterol. It "also fights
atherosclerosis by providing antioxidants, which prevent plaque formation."
Here is more information I came across on bilberries. It says
that it is a vasodilater. This means that it widens the blood vessels so the
blood pressure is lower. Due to its rich amounts of anthocyanosides, bilberry is an extremely valuable
treatment for a variety of disorders in which leaky veins cause tissue damage.
Containing over 15 different anthocyanosides, bilberry protects the veins and
arteries, as it boosts a great deal of physiological processes that results in
the improved integrity of capillary walls. Additionally, anthocyanosides prevent
platelets from sticking to the walls of vessels, which helps to prevent the
formation of blood clots.
Acerola cherries also contain anthocyans like other berries, but also
contains many times more vitamin C than oranges. Vitamin C is very good for
heart and cardiovascular health. A website says that acerola cherries helps high blood pressure,
protects against blood clotting and bruising, aids collagen formation and helps to prevent arthrosclerosis.
I have never seen them sold, but they are an ingredient in some supplements and
juices.
I love blueberries and I just found some great
news about the humble blueberry. In commercial
blueberry production, smaller species are known as "lowbush blueberries" (synonymous
with "wild"), and the larger species as
"highbush blueberries". Animal trials were conducted by
Marva Sweeney Nixon and her team of
researchers at the University of Prince Edward Island, PEI, Canada. They indicate that
the consumption of wild blueberries offers protection to the brain against damage
from ischemic stroke. Over 95% of people have the ischemic stroke (blocked
artery) instead of the hemorrhagic stroke (bleeding artery).
Nutritional
Neuroscience. 2002; 5(6): 427-431
New research by Dorothy Klimis-Zacas, Ph.D., and her team
of researchers at
the University of Maine, Orono, concludes that a diet of wild blueberries may
reduce risk from cardiovascular disease (CVD). These findings also suggest that
consuming of wild blueberries could help regulate blood pressure and combat
atherosclerosis. Studies show that they have the potential to
decrease the vulnerability of heart blood vessels to oxidative stress and
inflammation in animal models.
