The Sugar Film
Metabolic syndrome (1) is the medical term for a combination of diabetes, high blood pressure and obesity. It puts you at greater risk of heart disease, stroke and other conditions affecting blood vessels.
How to Reliably Give Metabolic Syndrome to Monkeys and People
As explained in That Sugar Film (7), fructose is a problem because it does not stimulate the pancreas to produce insulin.
In animal models, it even induces insulin resistance, leading to diabetes (9).
“the long-term consumption of diets high in fat and fructose is likely to lead to increased energy intake, weight gain, and obesity” (9).
Additionally, when taken by itself, fructose is poorly absorbed by the gastrointestinal tract, and it is almost entirely cleared by the liver since it’s absorbed through a different system than glucose. This makes the liver work harder, which leads to a fatty liver (10) which leads to obesity.
Sugar and Cancer
According to Mercola, sugar feeds cancer (4).
And according to the Journal of Clinical Investigation, sugar causes cancer, see Increased sugar uptake promotes oncogenesis via EPAC/RAP1 and O-GlcNAc pathways by Yasuhito Onodera, et al (5).
Definition of oncogenesis:
Carcinogenesis or oncogenesis or tumorigenesis is the actual formation of a cancer, whereby normal cells are transformed into cancer cells.
See Origins and evolution of the Western diet: health implications for the 21st century by Loren Cordain, et. al. (6):
Cancer is the second leading cause of death (25% of all deaths) in the United States, and an estimated one-third of all cancer deaths are due to nutritional factors, including obesity.
Ketagenic Diet and Cancer
Depriving cancer cells of glucose has also been proven to prevent cancer from growing, see the Ketogenic Diet.
Good Calories, Bad Calories
There is lots of great information in the book Good Calories, Bad Calories by Gary Taubes. Blurb:
For decades we have been taught that fat is bad for us, carbohydrates better, and that the key to a healthy weight is eating less and exercising more. Yet despite this advice, we have seen unprecedented epidemics of obesity and diabetes. Taubes argues that the problem lies in refined carbohydrates, like white flour, easily digested starches, and sugars, and that the key to good health is the kind of calories we take in, not the number. In this groundbreaking book, award-winning science writer Gary Taubes shows us that almost everything we believe about the nature of a healthy diet is wrong.
It takes about 20 years for excessive sugar intake to result in visible disease. One of the most interesting chapters in the book describes how it took 20 years for islanders from Tokelau to start suffering from Metabolic Syndrome when they adopted a western diet. In other words:
High sugar intake is hurting you continuously, but you won’t realise it for 20 years.
Fear, Uncertainty and Doubt
The scientific evidence against sugar, fructose and HFCS (High Fructose Corn Syrup) is overwhelming (1) (2) (3) (4) (5) (6) (7) (8) (9) (10). For more evidence, type “sugar” into www.pubmed.org.
Despite this, some organisations are attempting to confuse the issue by spreading Fear, Uncertainty and Doubt (FUD).
If you Google “sugar obesity”, you get the Sugar Association’s website as hit #5. They attempt to claim that “sugar is not the cause of obesity” (11). There are some problems with this claim:
- They do not provide any evidence for this.
- There are no references to any medical journals.
- There are no references to any animal studies.
- There are no references to any human studies.
- There are no citations on this page.
- In short, its not science, its a simple case of conflict of interest, similar to that of the Tobacco companies over the last 50 years. If the public reduced sugar consumption, then the share price of Coke and Pepsi would drop. There’s nothing wrong with profit, and nothing wrong with a share price dropping, but is it worth the human suffering?
The Sugar Association is also actively lobbying against public awareness (12).
If anybody says that sugar is not bad for you, then ask what medical studies they are basing their thoughts on.
For a normal, healthy person, would recommend avoiding fizzy drinks such as coke, and foods like donuts, high sugar desserts, and sweets.
We could summarise all of the information referenced on this entire page into one sentence:
No Fructose unless its in solid fruit.
As a rough guide:
- High Fructose Corn Syrup (HFCS) contains 50% fructose, so avoid that. Fortunately, HFCS is rare in the United Kingdom, however, it is very common in the USA.
- Normal table sugar contains 50% fructose, so avoid that as well.
- It’s fine to have solid fruit, as the amount of fructose is small compared to the bulk of the fruit, and it’s balanced by fibre.
- Avoid large quantities of fruit juice. Essentially, you want to limit the total amount of fructose you consume daily. If you extract the fructose out of 20 apples by juicing them all, that’s just like eating raw table sugar as far as the fructose content goes.
- Be aware of the hidden sources of sugar in your diet such as yoghurt, cereals and orange juice.
