Discussion Overview

The discussion centers around the relationship between fruit and vegetable intake and cancer risk, particularly in light of a recent study suggesting a weak association. Participants explore various perspectives on dietary habits, health outcomes, and the implications of lifestyle choices on cancer and other diseases.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express surprise at the study's finding that only about 2.5% of cancers could be averted by increasing fruit and vegetable intake, challenging long-held beliefs about their protective effects.
  • Others argue that the relationship between diet and cancer is complex, suggesting that a healthy lifestyle may lead to longer lifespans but potentially increase the likelihood of dying from cancer.
  • One participant notes the irony that improved health may correlate with increased cancer rates, proposing that in an ideal healthcare system, people would die from diseases like prostate cancer rather than earlier health issues.
  • Some discuss the role of genetics in cancer risk, with one participant sharing personal family health history that lacks cancer incidence, raising questions about the prevalence of such cases.
  • Several participants emphasize the health benefits of consuming fruits and vegetables, discussing micronutrient loss during cooking and the advantages of juicing, while others challenge the nutritional superiority of juices over whole fruits and vegetables.
  • Concerns about pesticides in non-organic produce are raised, alongside the practical necessity of pesticides for food supply sustainability.
  • There is a debate about the need for "colon cleansers," with some participants disputing the validity of such claims and advocating for the consumption of whole fruits and vegetables instead.

Areas of Agreement / Disagreement

Participants express a mix of agreement and disagreement regarding the health implications of fruit and vegetable consumption, the role of lifestyle in cancer risk, and the nutritional value of juicing versus whole foods. No consensus is reached on these topics.

Contextual Notes

Limitations in the discussion include varying definitions of health benefits, differing interpretations of study results, and unresolved questions about the long-term effects of dietary choices on cancer risk.

Amazing. Well I happen to like fruits and vegetables so I'll keep eating them.

The international team of researchers estimates only around 2.5% of cancers could be averted by increasing intake (of fruits and vegetables).

It's been drummed into my head nearly all my life that a diet that has lots of fruits and vegetables is protective against cancer (and I assumed that meant a bigger effect than 2.5%).

This latest study, which analysed recruits from 10 countries to the highly-regarded European Prospective Investigation into Cancer and Nutrition, confirms that the association between fruit and vegetable intake and reduced cancer risk is indeed weak.

I thought that was already a known fact!

Depends on exactly what they measured.
A healthy diet and healthy lifestyle greatly INCREASES your chances of dying of cancer.

If the choice is dying of a cardio-vascular disease at the age of forty or dying of prostate cancer at the age of 90.

Ah, interesting...so it's protective from a disease that kills relatively early, thus allowing you to live long enough to die of cancer, haha.

I'd like to see this study follow the cohort longer, to see if there's a difference in life span.
 
One of the ironies of modern medicine is that as the health of people improves cancer rates increase.
Ultimately in a perfect health care system everybody would die of things like prostate cancer!
 
Although things like smoking obviously increase your risk for developing cancer due to carcinogens, I think other types of cancer may be more inherited, or so it seems.

What is odd about my family is that most relatives on both my mother's and father's sides live into the late 90's and early 100's and there is no known history of cancer ever in either side of the family. I wonder how many people can say that? I wonder how common that is?

I can state unequivocally that no lifestyle would ever cause me to die of prostate cancer.
 
It appears that the source has slipped away.
 
its better to eat the grub than to eat the spray ?
 
It is important to eat fruits and vegetables because it provides health benefits. A person who eats more fruits and vegetables are likely to have little risk of chronic diseases. Fruit and vegetable juice is the ultimate key to giving a brighter, energetic life and truly optimal health. There are micronutrients in fruits and vegetables that are lost when they are heated. Cooking and processing vegetables and fruits destroys some of the important micronutrients by altering their chemical composition.

Fruits and vegetable juice provide our body with more nutrients. Juicing allows you to consume more vegetables than you usually eat. Our body needs the finest nutrient to be healthy. Nutrients are needed by our body too keep our organs healthy too. Though drinking fruit juices and vegetable juices is not a cure to diseases but it will help us to have a healthy lifestyle. It is also good to have a variety of vegetable juice, because by having a spice of vegetables and a variety of fruits you will have an optimum amount of nutrients.

If possible it is good to juice organic fruits and vegetables. Non-organic fruits and vegetables my contain pesticides. So when you juice non-organic fruits and vegetables the tendency is you peel fruits skin in order to remove chemical residue contents in higher concentration. But sadly most of the nutrients are found in the peel of fruits and vegetables.

Fruit juices tastes delectable than vegetable juices; be careful of spicing fruits and vegetable juices, it is better to have fruit juice and vegetable juice separately. Fruits juice is good in cleansing colon. Fruits and vegetables are good colon cleansers and they are easy to digest when eaten, but when you juice fruits and vegetables, some cleansing properties are lost so it is better to eat fruits and vegetables rather than juicing them.

All of this I agree with, and is true. Though, keep in mind that many processing plants will add nutrients to canned goods to "enrich" them and replace those destroyed by the canning process itself.

This you're going to need to provide some evidence to support. Most of juice is water. There's no reason that the juice of a fruit would have more nutrients than the fruit itself. Many of the nutrients would be left behind in the non-juice portion.

So when you juice non-organic fruits and vegetables the tendency is you peel fruits skin in order to remove chemical residue contents in higher concentration. But sadly most of the nutrients are found in the peel of fruits and vegetables.
Unfortunately, the reality is that our population size has long ago surpassed the ability to sustain our population on "organic" agriculture. I understand the concern about pesticices, but they are a necessary evil in order to ensure a sufficient food supply for the population we have. To allow insect and fungus damage to crops in the absence of pesticides would leave our population rather hungry.

There's no reason that fruit and vegetable juices need to be kept separate. In fact, one of the important aspects of a balanced diet is consuming all of the nutrients together so that those that are required for utilization of others are present at the same time. It is a complete myth that people need "colon cleansers." There are plenty of good reasons to eat your fruits and veggies without needing to resort to mythology.
