The Link Between Obesity and Cancer
Although the acceptance of the body is a good thing, can also be dangerous if potent risk factors for the deadly disease are simply ignored as "normal" in the process.
As noted in a recent statement position on obesity and cancer of the American Society of Clinical Oncology [6] (ASCO), obesity is "fast forward to snuff as the leading preventable cause of cancer . "
To address this cause is overlooked cancer, ASCO has established a "multi-faceted initiative" which includes:
- Education to raise awareness about the evidence linking obesity and cancer
- tools and resources to help providers obesity oncology address with their patients
- Research
- Advocating policies and systems change to addressing the social factors that contribute to obesity and improve access to weight management for cancer patients
Processed Foods Drives obesity and cancer epidemics
the obesity epidemic is directly linked to excessive consumption of sugar (almost all processed foods alone now loaded with hidden sugar and fructose, including baby food and food intended as "health food"), and this is also an important factor vector for cancer epidemic.
The link between a diet high in sugar, obesity and cancer can be summarized in two words: insulin resistance. Both obesity as a result of cancer when the body loses its ability to burn fat as fuel.
Sugar also causes chronic inflammation, which also increases the risk of cancer. And, as noted in the article by CNN offered: [7]
"Fat tissue also produces hormones called adipokines, which can stimulate or inhibit cell growth [8] ... If these hormones are out of balance, the body may not be able to adequately fight cell damage. "One of the most effective ways to reverse insulin resistance is intermittent fasting, besides making some basic changes in your diet, which revolves around restricting the intake of sugar and fructose, and replacing carbohydrates with healthy fats.
Studies show obesity-cancer link
A number of studies have linked obesity with an increased risk for a dozen different types of cancer, including cancer colon, esophagus, kidney, breast and pancreas, as well as an increased risk of dying from the disease:
- a study over 16 years [9] published in 2003 that included more 900,000 Americans found that obese participants were more likely to be diagnosed and die of cancer, compared with those of normal weight. According to the authors, obesity "could be responsible for 14 percent of all cancer deaths in men and 20 percent of women";
- A recent report published in the journal Cancer Research [10] projects the incidence of cancer and cancer death in the US will continue to increase over the next decade and a half, largely due to rising obesity rates;
- A recent study [11] involving 80,000 patients with breast cancer found that pre-menopausal women with a body mass index (BMI) greater than 30 had a probability of 21.5 percent death, while women with average BMI had a 16.6 percent chance of dying from the disease;
A recent study published in the peer-reviewed journal Archives of Internal Medicine [12] found that most adults (just over 71 percent) receive 10 percent or more of their daily calories from added sugar. About 10 percent of American adults receive 25 percent or more of their daily calories from sugar!
On average, Americans consume about 350 calories a day of sugar, equivalent to about 22 teaspoons, and this is a sure recipe for chronic poor health ...
In the JAMA study just mentioned, those who consumed 21 percent or more of their daily calories as sugar were twice as likely to die of heart disease compared to those who received seven percent or less, or daily calories from sugar.
The risk was nearly tripled among those who consumed 25 percent or more of their daily calories from sugar.
But cancer is also fueled by excess sugar, so that the risk of cancer, while it was not evaluated here, there is little doubt that the risk of cancer will increase right along with the risk of heart disease ...
Your body has a limited ability to process sugar
the main problem with sugar, fructose and processed, in particular, is the fact that your liver has a very limited ability to metabolize.
According to Dr. Robert Lustig , you can safely use about six teaspoons of sugar per day unless you are doing strenuous exercise. But the average American consumes 22 teaspoons of added sugar a day.
All that excess sugar is metabolized into body fat, and leads to all chronic metabolic diseases we struggle with, including cancer.
Four grams of sugar is equivalent to a teaspoon, and I strongly recommend limiting your daily intake of 25 grams of fructose or less from all sources, including natural like fruits. That amounts to little more than six teaspoons of sugar a day.
If you are among the 80 percent majority who have insulin or leptin resistance (overweight, diabetes, high blood pressure, or taking a statin drug), it is best to restrict their consumption total fructose for as little as 15 grams per day, until it has returned to normal levels of insulin and leptin.
While lack of exercise certainly plays a role in increasing obesity rates [13] between children and adults, it is important to understand that you can not exercise your way out of a poor diet.
The food industry has a responsibility here that has, until now, could not accept. more than $ 1.8 trillion of junk food marketing to children each year is spent [14], while paying lip service to concerns about obesity now and then promote exercise.
These junk foods are also loaded with processed chemicals similar to hormones that further contribute to cancer and other health problems. In short, the current generation of children raised on a diet of processed foods have a much higher risk of devastating health problems than their parents, thanks to the processed food industry.
The risks are significant. In girls, obesity exposes them to higher levels of estrogen because estrogen is both produced and stored in fatty tissue.
Carrying girls excess body fat therefore have more estrogen and leptin, which can lead to insulin resistance and the development of more fatty tissue, causing further estrogen is a vicious cycle that can result in precocious puberty, and raises the risk of estrogen sensitive cancers such as breast cancer later in life.
Understanding the sugar connection-cancer
Cancer cells need glucose to thrive, and if you have insulin resistance, it does not matter if glucose coming from sugar, fructose, or grains added.
In order to starve cancer cells or prevent them from forming in the first place, you have to remove their main food source, ie, sugars, which include all carbohydrates vegetables .
In 1934, Otto Warburg received the Nobel Prize for his research on the physiology of cancer cells, which clearly demonstrates the cancer cells need more sugar to thrive.
Unfortunately, many oncologists have not yet fully understood the importance of this knowledge, nor apply when developing a treatment plan for cancer. Not everyone has no idea, though.
Lewis Cantley, director of the Cancer Center Medical Center Beth Israel Deaconess School of Medicine at Harvard, said that as much as 80 percent of all cancers are "driven by mutations or environmental factors work to enhance or mimic the effect of insulin on tumor cells emerging. "[15]
Even in terms of treatment, the cancer has been shown to respond to diet alone. A ketogenic diet , which is high in healthy and very low sugar fats, especially for those who are insulin resistant, it has been shown to reverse the cancer in many cases, and research shows great promise in this area .
can be very useful in the treatment of insulin resistance junior. Once the insulin resistance is resolved, a ketogenic diet is usually not necessary.
Recent research [16] has added to the knowledge base, showing that not only cancer existing supply sugar; also it seems to initiate cancer growth.
As reported GreenMedInfo.com , [17] this study:
" '... Provide [s] evidence that increased glycolytic activation itself can be an oncogenic event ... 'against insulin resistance, you must reduce sugar consumption
"That is, activation of metabolism of sugar based on a cell - driven by both the presence of higher amounts of glucose and receptors increase glucose surface of the cell membrane (ie, "overexpression of glucose transporter ') -. Units cancer initiation on the other hand, the study found that" on the contrary, the forced reduction of glucose uptake by cancer cells breast led to phenotypic reversion. "
" in other words, interfering with sugar availability and absorption cell causes the cancer cell to REVERSE to its structure-precancer function (phenotype). "
If you are overweight, step number one is to reduce the overall consumption of sugar and grains.
recommend keeping total consumption of sugar / fructose below 25 grams a day, or as little as 15 grams a day if you have health problems related to insulin and leptin resistance, such as high blood pressure, diabetes or heart disease, until their sensitivity to insulin / leptin has been restored.
One of the easiest ways to drastically reduce their consumption of sugar and fructose is by switching to a diet of whole, unprocessed foods, since most of the sugar in your diet comes from processing fee.
Ideally, the target of
- Avoid processed sugar / fructose, grains and processed foods
- Eat a healthy diet of whole foods, ideally organic, and replace grain carbohydrates with:
- large quantities of vegetables
- -low a moderate amount of high quality protein (think organically raised, grazing animals )
- as high quality of healthy fat as desired (saturated and monounsaturated sources of oil and tropical animals). Most people who really need more than 50-85 percent of fat in your diet for optimal health far from the 10 percent currently recommended.
Other ways to reduce your sugar intake include:
- Cutting the amount of sugar you add personally to your food and drink
- The Stevia or use of Luo Han instead of sugar and / or artificial sweeteners. You can learn more about the best and worst of sugar substitutes in my previous article, " sugar substitutes, what is safe and what is not "
- The use of fresh fruit instead of canned fruit or sugar to foods or recipes that require little sweetness
- the use of spices instead of sugar to flavor your food
intermittent fasting - One of the most effective ways to reverse insulin / leptin resistance
After solving your options staple food, can further enhance their efforts loss fat by incorporating the principles of intermittent fasting.
Exercising in a fasted state will bring it increased further. A simple way to start working with intermittent fasting is simply skip breakfast, lunch make the first meal of the day.
I usually recommend this type of eating schedule, but if you want to eat breakfast and dinner instead jump, that's fine too. The key is to limit your diet to a narrow window specific time each day (about 6-8 hours) instead of eating every two to three hours throughout the day.
intermittent fasting is by far the most effective way I know of to eliminate unwanted fat, eliminate sugar cravings, and normalize their sensitivity to insulin / leptin.
fast intermittent helps restore your body to use fat as the main fuel, and confirms the growing evidence that when your body adapts to burning fat instead of sugar as its main fuel, dramatically reduces the risk of chronic diseases.
Another mechanism that causes intermittent fasting effectively for weight loss is the fact that causes the secretion of HGH [18] -. A hormone fat burning has many well-known health benefits and fitness "anti-aging"
Daily intermittent fasting tends to have the highest rate of compliance, and growing evidence suggests that intermittent fasting can provide many, if not most of the same benefits as longer and rigorous fasts.
Again, when daily fast, food is restricted to a specific time window, such as a window eight hours or less.
This is every day until your insulin resistance / improvement leptin (which means that your weight, blood pressure, cholesterol ratios, or diabetes normalizes). After that, you just need to do it as often as necessary to maintain good health.
baseline
If you want to reduce, and in many cases virtually eliminate the risk of cancer and other chronic diseases, I suggest you get serious about restricting the consumption of sugar / fructose to 25 grams per day - or less if you are already struggling with insulin-related health issues -. and give you an opportunity intermittent fasting
Again, it is not necessary to continue with intermittent fasting for the rest of your life (unless you really want). I think most people who are insulin / resistance would benefit from doing so continuously until leptin resistance is resolved.
However, once your weight is ideal, and has high blood pressure, abnormal amounts of cholesterol or diabetes, then you may eat more frequent meals until or unless yields of insulin resistance / leptin.
Remember, exercise will not make a diet too rich in sugar, and such a diet will destroy many of the benefits of exercise too boot. So you really need to address what and when you eat if you want to eliminate excess weight and reduce the risk of cancer and other chronic diseases.
There is no magic formula, but a healthy lifestyle can be as close as you'll ever get to one.
