Obesity = Inflammation = Cancer

January 22nd, 2010

Every January 1st, millions of people resolve to get in shape and lose weight.

Unfortunately, before February 1st rolls around, two thirds of those people have fallen off the bandwagon, abandoned their gym memberships and returned to the normal diet of pizza & ice cream.

So, in an attempt to recharge your collective weight-loss motivation, I thought I would let you in on a recent piece of obesity research that concluded that…

Obesity = Inflammation = Cancer

.

Yep, cancer…the big C.

.

According to this latest research, obesity enhances the development of a form of liver cancer called HCC (hepatocellular carcinoma) by:

  1. Stimulating the production of tumor-promoting cytokines (interleukin-6 {Il-6} and tumor necrosis factor {tnf})
  2. Il-6 and tnf causes inflammation in your liver, and
  3. Activates a tumor-producing transcription factor called STAT3
  4. STAT3 activates the formation and growth of the HCC liver cancer

Or, in layman’s terms

Obesity = Inflammation = Cancer

But, it’s not just liver cancer.

Obesity also increases the risk of developing pancreatic, GI and kidney cancers.

.

So, how about that slice of pizza?

Feeling hungry?

Doctors Ignore Obesity

September 30th, 2009

dr-julius-hibbert

So, how come “many overweight patients are not being advised to lose weight, diet, or exercise”.

In fact, when it comes to medical intervention in cases of obesity, the numbers are as follows:

  1. Having a doctor tell the patient about the health problems associated with being overweight (48.0%),
  2. Suggesting diet and exercise (46.5%),
  3. Referring the patient to a formal diet program (5.2%),
  4. Prescribing a weight loss medication (4.0%),
  5. Recommending a non-prescription weight loss product (1.8%),
  6. Recommending stomach bypass surgery (1.5%).

I don’t know about you, but considering that obesity is fast becoming the western world’s #1 health issue, I think that the global medical community should be taking obesity prevention/treatment much more seriously.

I don’t know if it’s a lack of knowledge or the threat of discrimination lawsuits or the frustration of being ignored by obese patients over and over and over, but if we want to reverse the tide of obesity related disease, real steps need to be taken.

The time for talk is over.

Obesity = Cancer

February 23rd, 2009

Cancer cases are now rising at such a rate that the disease poses a threat to humanity comparable to climate change.

So what?… you don’t smoke, live under power lines or work at a nuclear power plant.

gut

That may be true, but you haven’t seen your toes in years, and according to a report co-published by the World Cancer Research Fund and the American Institute for Cancer Research, a third of cancers are caused by diet and lack of exercise.

And if that wasn’t bad enough, according to the new WCRF/AICR report:

  • About seven million people die from cancer worldwide each year.
  • That number is expected to rise to more than 10 million by 2020.
  • The estimated number of new cases annually is set to increase from 10 million now to 16 million by 2020.
  • Overall the toll is predicted to double in the next 40 years.

Because of these facts, the WCRF/AICR has identified global obesity as it’s primary target in their war against cancer.

According to British researcher Sir Michael Marmot,

“When we look at what’s happened to obesity levels in this country(England), it’s growing at an alarming rate. Anybody looking at the evidence would say there must be social and economic causes of that. It can’t be that 20 million people individually said, ‘I’ll think I’ll get fat.’”

Marmot acknowledged the extra challenge posed by the recession, which has led to booming sales for fast food chains. “It is going to be difficult, but in a way it’s even more urgent to ask what needs to be done, because if you do nothing and the recession forces people into cheaper, unhealthier options, that only highlights that the unhealthy options tend to be the cheaper ones.”

WCRF/AICR is calling on individuals to take responsibility for themselves and their children, while stressing the need for action from governments, multinational corporations, civil society, industry, workplaces, schools, the media and health professionals. Marmot cited the provision of cycle lanes, gyms and swimming pools as measures encouraging people to exercise. He welcomed the congestion charge in London as having prompted more people to cycle to work.

Marmot, who is also chair of the World Health Organisation’s Commission on Social Determinants of Health, is braced for the charge that he is advocating a nanny state approach.

He cited two examples of communicable diseases, smallpox and water-borne diseases, which collective social action have largely eliminated. “We didn’t say at the time, ‘Oh, this is the nanny state providing clean water for people – people should decide for themselves whether they want to drink water with cholera in.’ Nobody would say that today. Diet is a bit more complicated but we want the availability of a nutritious supply of food.”

Obesity has social and economic causes, he added, and therefore social and economic solutions. “We’re worried in this country, but it’s also Egypt, Mexico, Brazil, middle-income countries. In Egypt two thirds of women are overweight or obese. Mexico has frightening levels of obesity in middle-class kids … they’ve gone from fajitas to fast food, with nothing in between.”

Hmmmm…fast food causing obesity.

What to do, what to do???

The One Diet That May Actually Save Your Life

September 12th, 2008

After looking at 12 studies that followed more than 1,500,000 people over a span of 18 years, researchers at the University of Florence have determined that people who followed the Mediterranean Diet were:

  • 9% less likely to die from heart disease or other cardiovascular ailments
  • 6% less likely to develop or die from cancer
  • 13% less likely to contract Parkinson’s or Alzheimer’s disease

According to WHO and CDC statistics, adherence to a Mediterranean diet would result in:

So What Is The Mediterranean Diet?

While it varies slightly from region to region, the Mediterranean Diet is based primarily on:

Fresh, healthy food: The staples of the Mediterranean diet include fresh fruits and vegetables, whole grains, nuts and seeds, legumes, seafood, yogurt, olive oil, and small amounts of wine. Food should be eaten in season and locally grown, and Mediterranean dieters avoid processed food.

Portion control: The Mediterranean diet focuses on small portions of high-quality food. “When food tastes delicious, a little is enough because your senses have been satisfied,” And healthy fats like olive oil and nuts, which are staples of the Mediterranean diet, keep you feeling fuller longer than diets that restrict fat or forbid it altogether.

Healthy fats: Unlike most diets, the Mediterranean diet doesn’t cut fat consumption across the board.  Rather than limiting total fat intake, the Mediterranean diet makes wise choices about the type of fats that are used. On the menu are the monounsaturated fat found in olive oil, nuts, and avocados; and polyunsaturated omega-3 fatty acids, found in fatty fish (salmon, tuna, sardines, and trout); and fat from plant sources, like flaxseed. Limiting processed and packaged foods keeps the diet extremely low in unhealthy trans fats, which have been shown to increase the risk of heart disease and strokes.

Olive oil: The Mediterranean people use olive oil in almost everything they eat, including pastas, breads, vegetables, salads, fish, and even cakes and pastries. It’s the principal fat in the Mediterranean diet, replacing other fats and oils, including butter and margarine. What’s so healthy about olive oil? Researchers at the Monell Chemical Senses Center in Philadelphia found that oleocanthal, a compound in olive oil, may reduce inflammation, which could help prevent conditions like heart disease, diabetes, arthritis, Alzheimer’s, and autoimmune diseases, as well as certain cancers.

Omega-3 fatty acids: Found in abundance in the Mediterranean diet, omega-3 fatty acids are bursting with health benefits. Fatty acids have been shown to reduce the incidence of heart attacks, blood clots, hypertension, and strokes; and may prevent certain forms of cancer and lower the risk of neurological disorders like Alzheimer’s disease.

More vegetables, less meat: “A diet higher in plant foods and lower in animal products has been linked to decreased incidence of heart disease, diabetes, and many cancers.”  The traditional Mediterranean diet is practically vegetarian, with lots of fish and very little meat. As for vegetables, Mediterranean people feast on tomatoes, broccoli, peppers, capers, spinach, eggplant, mushrooms, white beans, lentils, and chick peas.

Wine: Many Mediterranean people drink a glass or two of wine each night with dinner. But portions are small, generally about three ounces (a third of a small wine glass or two shot glasses). When taken in small amounts, wine has been linked to lower rates of heart disease, likely due to the presence of antioxidants like transresveratrol and oligomeric proanthocyanidin (OPC), which keep blood circulation healthy and prevent blood clots from forming.

Whole grains: Whole grain foods like bread, pasta, potatoes, polenta, rice, and couscous are a key part of the Mediterranean diet. In their natural state, grains are full of cancer and heart disease-fighting fiber, vitamins, minerals, and nutrients. But stripping the grain’s outer layers to make white flour and white rice eliminates these benefits, reducing the healthy whole grain to little more than empty calories. Whole grains provide energy and calories with little fat, and because they’re slow to digest (thanks to their high-fiber content), they help you feel fuller longer.

Fruit for dessert: Forget pie a la mode and chocolate cake. For Mediterranean people, fresh fruit is the typical daily dessert. Taking advantage of fruit’s natural sweetness has double benefits. First, what you gain: the fiber and nutrients in fruits like apples, grapes, and oranges. What you lose: the added sugar, calories, chemicals, and unhealthy fats in sweet, processed desserts.

And we can only imagine what would happen to those health statistics if Mediterranean dieters were to increase their physical activity.
