Juices and Juicing - Questions and Answers ABOUT FOODS AND CANCER PREVENTION AND SURVIVAL

QUESTION: How do fruit and vegetable juices compare to eating these foods whole?

ANSWER: As a rule of thumb, it’s important to shoot for consuming at least
three servings of fruit and four servings of vegetables every day. Since juice
is not as high in fiber as whole fruit or vegetables, it is always best to consume
the whole food whenever possible. It has been shown that diets higher
in fiber are not only beneficial for protecting against a number of cancers
and chronic illnesses, they also help fill you up so that you don’t “fill out.”
Maintaining a healthy weight helps reduce cancer risk.
For people who don’t enjoy eating lots of fruits and vegetables, juicing
can be a way to bring these nutritious foods into their routine. One-half cup
(4 fluid ounces) of juice can be considered the equivalent of a single serving
of fruits or vegetables. Juice made in a high-powered blender that retains the
fiber in the food is best. Alternatively, use the fibrous end-product that
juicers produce by adding it to salads, soups, stir-fries, or pasta sauces.

If a completely plant-based diet isn’t possible for me, is it okay if I eliminate red meat and cheese and eat a low-fat diet with egg whites, chicken, fish, and skim milk in addition to lots of fruits and vegetables?

General Nutrition - Questions and Answers ABOUT FOODS AND CANCER PREVENTION AND SURVIVAL

QUESTION: If a completely plant-based diet isn’t possible for me, is it okay if I eliminate red meat and cheese and eat a low-fat diet with egg whites, chicken, fish, and skim milk in addition to lots of fruits and vegetables?

ANSWER: Eliminating red meat and cheese is a start. However, you’ll want
to go further and base your diet on whole grains, legumes, vegetables, and
fruit. Your diet will be much richer in cancer-fighting vitamins, minerals,
fiber, and phytochemicals. Chicken and fish contain fat—including significant
amounts of saturated fat—as well as cholesterol and other harmful
compounds, so the most health-promoting diets avoid them completely.
Skim milk and egg whites contain animal protein and cholesterol and no
fiber, vitamin C, or healthful complex carbohydrate.
An easy way to shift to a completely plant-based diet is to do it 100
percent for three weeks. In the process, you will adjust to new flavors and
tastes. As those twenty-one days fly by, see how you feel. You’ll realize that
you feel a lot better (and perhaps lighter!) and that you don’t miss the highfat
foods.

Increased Vegetables and Fruits

Increased Vegetables and Fruits in Foods and Breast Cancer Survival - How Foods Fight Cancer

Some evidence suggests that women whose diets are richer in vegetables
and fruits tend to survive longer.2,18 In a study of 103 women in Australia,
who were followed for six years after they were diagnosed with breast cancer,
those who consumed the most fruits and vegetables rich in beta-carotene or
vitamin C had the best chance for survival. The researchers divided the
group into thirds based on how much beta-carotene they got each day in
the foods they chose. It turned out that in the group getting the least betacarotene,
there were twelve deaths over the next six years. In the middle
group, there were eight deaths; and in the high-beta-carotene group, there
was only one death.19

In the digestive tract, beta-carotene is converted to vitamin A. In turn,
vitamin A is converted to a compound called retinoic acid, which has a
demonstrable anticancer effect on cells in test-tube studies.16 A Swedish
study found much the same thing: Among women with breast cancer, those
consuming more vitamin A were more likely to have estrogen receptor-rich
tumors, a good prognostic sign.17

The Australian researchers also analyzed their data in another way,
looking simply at how much fruit of any kind the women had been eating,
including both beta-carotene-rich fruits and other varieties, such as apples,
bananas, berries, grapes, and dried fruits. The same sort of pattern
emerged. In the group eating the least fruit, there were twelve deaths; in the
middle group, there were six deaths; and in the group consuming the most
fruit, there were only three deaths.19

Similarly, a study of Canadian women with breast cancer found that
those getting the most beta-carotene and vitamin C had significantly better
survival odds.9 The benefit was dose related, meaning the more of these
helpful nutrients they got, the better they did. Those who got more than 5
milligrams of beta-carotene per day had double the likelihood of survival
compared to women who got less than 2 milligrams. To understand what
this means on your plate, there are about 5 milligrams of beta-carotene in
half a medium carrot or one-fourth cup of cooked sweet potato.

For vitamin C, those getting more than 200 milligrams each day had
roughly double the survival odds compared to those getting less than 100
milligrams per day. In practical terms, an orange has about 60 milligrams
of vitamin C, and a one-cup serving of broccoli or other green vegetables
has about 80.9

Vitamin E may have the opposite effect. In one study, women with
breast cancer consuming larger amounts of vitamin E had poorer survival.
Every one-milligram increase in daily vitamin E intake was associated with
approximately a 15–20 percent increased risk of treatment failure.8

Pomegranate juice may slow prostate cancer after treatment

Pomegranate juice may slow prostate cancer after treatment

According to the long-term study published in the 104th Annual Scientific Meeting of the American Urological Association, in Chicago 25-30 April 2009 found that pomegranate juice may slow the progression of prostate cancer recurrence after medical treatment.

Two-stage trials conducted on 48 participants for more than 6 years. Having experienced radio therapy or surgery, levels of PSA (Prostate Specific antigen) increased patient. These patients were then given to drink 8 oz of pomegranate juice every day. After 6 years lowered his PSA levels as much as 60%.
