Are Berries Really Cancer Fighting Super Fruits?

Acai, the #1 Super Fruit.
Phytochemicals do seem to slow tumor growth, but the "key" is in the variety of foods.
These mini super fruits of large stature are often described as “super foods,” but then, so are many other foods.
So are these tiny fruits really such a nutritional powerhouse, or are they just one more fruit option?
And is one kind really better than the rest?
Research does show that these are among the fruits highest in antioxidant content and that they are excellent sources of several phytochemicals that seem to help block cancer development.
However, other fruits and vegetables provide different nutrients and phytochemicals with unique health benefits.
The best advice then, is to eat them often for their great taste and health boost, but stay focused on the main goal of eating a wide variety of produce every day.
All are known to be excellent sources of vitamin-C, providing as much or more than a whole day’s recommended amount in just one cup.
But all are good sources of vitamin-C, with one cup of raspberries or blackberries giving you close to half the amounts currently recommended for a whole day for adults.
One of the ways vitamin-C protects our health is its function as an antioxidant.
Antioxidants attract and neutralize highly reactive molecules called free radicals that could otherwise damage body cells in ways that initiate cancer development, heart disease and age related eye damage.
Yet laboratory studies show that much of the antioxidant power of super fruits and vegetables comes not from the classic antioxidant vitamins such as vitamin-C, but from natural protective compounds called phytochemicals.
Anthocyanins are a group of phytochemicals that give many their red color.
In laboratory studies, anthocyanins inhibit growth of lung, colon and leukemia cancer cells without affecting growth of healthy cells.
Decreased cancer development is also seen in animals given anthocyanins.
Ellagic acid is another important phytochemical in virtually all of these mini-fruits.
More than a simple antioxidant, ellagic acid also blocks metabolic pathways that can lead to cancer.
In animals, it has inhibited development of colon, esophageal, liver, lung and skin cancers stemming from a variety of carcinogens.
Pterostilbene is yet another powerful antioxidant phytochemical that seems to affect metabolic processes to decrease development of both cancer and heart disease.
In fact, many are an excellent source of this relative of the health promoting resveratrol that is found in grapes and red wine.
(In fact you'll want to read; Blueberries are Miracles) Phytochemicals seem to be a vital part of the benefits we get from these super foods.
One study showed that strawberries’ power to inhibit cancer cell growth was unrelated to their antioxidant content, suggesting that the direct influences of the phytochemicals on cancer development are very important.
An Essential Question Does Remain:
Do normal portions give us enough phytochemicals to get protective benefits or do we need to eat larger portions than standard 1/2 cup servings?
Some research does suggest that concentrations normally found in the blood after eating are enough to substantially decrease cancer cells’ growth and to stimulate their self destruction, but more study is required.
Overall, research on phytochemicals shows that looking at the effects of single foods does not show the full picture.
Studies show that a wide range of phytochemicals found in fruits, vegetables, whole grains and beans act together in ways far greater than would be expected from looking at them individually.
That’s why, as fabulously healthy as these mini super fruits are, the bottom line has to be abundance and variety of many fruits and vegetables.
Champagne with Pomegranate
Champagne and many fruits are a perfect combination.
Summer varieties combined with a splash of pomegranate juice make this a great brunch beverage.
1/2 pint raspberries
1 bottle dry champagne or sparkling cider
1/3 c. pomegranate syrup
Combine the pomegranate syrup and champagne in a 2 to 4 quart pitcher and mix thoroughly.
Fill champagne flutes to within 1 inch from the rim and float 2 or 3 super fruits on top.
(you can also use pomegranate seeds if you like)
Have fun, we know you want to!Tweet
