Liver cancer, pill, sugars, fructose and rodents in experimental studies
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770276/?fbclid=IwAR1x7XrakGf67kviE5ax1MYEWqP3N2eR7z4kFcaBoIaj27F8eVGjI0okLdI

| Avoiding sugars including fructose don't prevent or protect liver cancer |
The issue is that we have to be careful especially when advising cancer patients because except for some tumours which exhibit a metabolic rigidity, avoiding sugars don't cure cancer and we are far from being able to assert that it could prevent it...
The contraceptive pill increases benign tumours in the liver but as far as I know avoiding sugars don't prevent this to occur.

Low Carb diets work
Figure 1: Impact of popular ‘healthy’ foods on blood glucose
The glycaemic index (GI) ranks the carbohydrate levels of different foods to help predict their effect on blood sugar compared with pure glucose, which has a GI of 100. However, GI does not take account of the density of each carbohydrate in a portion of food — the glycaemic load, which is derived from the GI, is needed for this. The infographic shows the glycaemic load for a typical serving of various foods that are thought of as ‘healthy’, represented as the equivalent in teaspoons of sugar.

| Very useful: don't care about the GI, just keep in mind the amount of sugar, you may eat a teaspoon of honey but avoid cereals and products of cereals flour. |

Maillard's molecules in UHT milk which is processed milk
3. MRPs on Milk Processing
Milk is a beverage that is consumed throughout the world. At present, a large percentage of the milk consumed by people, especially in the western countries, is processed rather than raw milk. Ultra high temperature (UHT) treatment or conventional sterilization process is often used to process milk for improving quality and safety. Milk is rich in protein and sugar. So it is obvious that processing of milk at high temperature may lead to the formation of MRPs. Several methods have been approached to determine the extent of MRPs during milk processing. Both initial and advanced staged MRPs have been used as indicators of browning reaction which occurred in milk [11, 12]. MRP formation affects protein and mineral bioavailability greatly. In the early stages, lactose in milk blocks the amino group of lysine to form the Amadori product called lactulosyllysine which changes the protein bioavailability [13]. It is also known that MRPs may behave as chelating agents to chelate metal cations by forming different soluble and insoluble complexes and thereby can affect mineral bioavailability [14]. So processing of milk by heat-treatment requires attention, especially for the infants, as milk is the sole source of nutrients at that stage of life.
It has been reported that conventional sterilized bottle milk has different chemical composition compared to the UHT treated milk [15]. HMF level is often used to assess the progression of MRPs formation. However, milk processed at UHT may have different levels of HMF [16] due to the presence of some other factors such as vitamin A, casein, and iron [17]. So during milk processing, along with heat treatment, other relevant factors should be considered for preserving the nutritious value. A recent study has shown that use of enzymes like Faox I and Faox II might inhibit Maillard reaction development [18].

Yes, they are. It is complete fermentation stupid!
Keto wines are real: don't be abused by residual sugars per serving... Only RS by litre does matter and it should be less than 0.5g/l...
Some features which matter:
Pure, artisanal, and deliciously clean. It means that the fermentation process is complete...

One universal diet cannot fit all
Diets are not one-size-fits-all. So why do we treat dietary guidelines that way?

By Nina Teicholz
May 2 at 9:12 AM
Nina Teicholz is a journalist, adjunct professor at New York University and author of “The Big Fat Surprise.”
The Dietary Guidelines for Americans are the single most powerful influence on American food choices. They drive dozens of public and private programs, from school lunches to meals for the elderly, the military, hospitals and more. They’re also adopted as the “gold standard” by health-care practitioners for sick and well alike. When your doctor or nutritionist or diabetes educator hands you a diet to follow for a particular disease, you are given the guidelines. Yet at the kickoff meeting for the next Dietary Guidelines, government officials made clear that this policy is only appropriate for healthy people. The 60 percent of our population diagnosed with nutrition-related diseases — obesity, diabetes, dementia — is excluded. On this path, there’s little question that the government’s guidelines will do virtually nothing to reverse the epidemics of these diseases.
This narrow focus clearly came as a surprise to some members of the 20-person appointed expert committee tasked with overseeing the science of the 2020 guidelines. They’d been gathered in Washington by the Departments of Agriculture and Health and Human Services, which jointly oversee the policy. One committee member asked, for instance, whether a study on obese people that looks primarily at weight loss would be included. The answers, from USDA staffers, came back repeatedly: That study would likely be excluded; that most included studies are only of populations that are healthy or at risk for obesity; and the guidelines are for “prevention” only.
Why is this “prevention” diet not appropriate for sick people? Recent science indicates that many people with nutrition-related diseases typically have a “broken” metabolism that makes them far less able to process starches and sugars. While some people can reverse obesity and diabetes with calorie restriction, others find more success reducing carbohydrates alone — for example, eating fewer grains and/or sugary foods. For these people, USDA and HHS should offer a nutritional option that is lower in carbohydrates than the existing guideline options, which all stipulate eating 50 to 55 percent of daily calories as carbohydrates.
A lower-carbohydrate approach could be a windfall for many. It has been demonstrated to work whether one is merely overweight or formally “obese,” prediabetic or “diabetic.” As a patient slides from the “pre” state of disease into its full-blown horror, a diagnosis is essentially just a name-change. One’s metabolic health has been steadily declining all along, and the solution for reversal, independent of one’s position along that downward slope, is the same. This means USDA and HHS’s hard-line distinction between “prevention” and “treatment” of chronic diseases is often meaningless.
That the guidelines are not for all Americans has been known for some time. It was one of the reasons that in 2015, during the last review of the guidelines, the House Agriculture Committee summoned the heads of both the USDA and HHS to the Hill for a lengthy hearing. Both Democrats and Republicans heavily criticized the current approach, no doubt responding to the law that states that the guidelines should be for a “general public.” Shortly after this hearing, Congress appropriated $1 million for the first-ever outside peer review of the guidelines’ process, by the National Academies of Sciences, Engineering, and Medicine. Regarding the policy’s scope, the report stated, “Given the range in health status and the prevalence of chronic diseases in the population . . . it is essential that future DGA be developed for all Americans whose health could benefit by improving diet.”
The USDA gives a nod to the “general public” requirement in its 2020 charter for the guidelines. However, in practice, the agency is clearly designing a program for healthy people only.
Nutrition-related diseases kill about 4,300 people daily, according to the Centers for Disease Control and Prevention — the equivalent of nearly 11 jumbo jets crashing and killing every person on board, every day. Where are the emergency expert panels, the headlines, the congressional outrage devoted to this massive, unparalleled public health crisis? The guidelines, whether through design or implementation, are clearly a failed policy. It’s time to ground the planes and acknowledge this disaster. Independent experts with no vested interest in the status quo are urgently needed to rethink the problem.
The USDA has already resisted reforms to improve the guidelines development process by avoiding conflicts of interest on the current advisory committee. (One member, for example, is the medical director on a meal replacement program owned by Nestle, one of the world’s largest food companies.) So the committee is unfortunately unlikely to undertake this much-needed radical overhaul. Nor do the odds seem high that the USDA office in charge of this policy for decades will turn a critical spotlight in on itself. But something has to change. The government is spending $12 million on guidelines for 40 percent of us, at most. It’s time we get away from a one-size-fits-all diet and instead have a range of options that could together be a Dietary Guidelines for All Americans.

Insulin is a driver of obesity
The worldwide obesity epidemic could be tackled by better understanding of how insulin works, according to a world leading expert on intermittent fasting and low carb diets.
Dr Jason Fung, a Canadian nephrologist, was interviewed as part of a nutritional report on BBC Radio 4 which investigated why obesity rates have risen in the UK across the last several decades.
Speaking to journalist Becky Milligan, Dr Fung said: “Insulin basically tells the body to store fat and it also turns off fat burning, so if your body is storing fat, you don’t want it to burn fat.
“If insulin falls, then that’s a signal to burn fat, so if insulin is high you store fat, if it’s low you burn fat. Certain foods stimulate insulin much more than other foods. So refined carbohydrates are probably the biggest stimulus to insulin.”
Dr Fung has written three best-selling health books and he co-founded the Intensive Dietary Management program which helps people lose weight and control they type 2 diabetes better.
‘Appalling’ rates
Dr Robert Lustig, Professor of Paediatrics in the Division of Endocrinology at the University of California in San Francisco, agreed, saying that the obesity issue is “nothing to do with calories”.
He is urging the government to start focussing on insulin and how the hormone works within the body, providing an example of a 2012 study that focussed on the consumption of how sugar in drinks can impact someone’s weight.
The trial compared sugary drinks, to diet drinks, milk and water. Those in both the soda groups put on weight, even though the diet version products were completely calorie free.
Dr Lustig added: “Calories being calories are the gravy train of the food industry, because if there were specific calories that caused you to gain weight, or there were specific calories that caused chronic metabolic disease such as type 2 diabetes, then the public would shy away from those wouldn’t they? Well, that is processed food.”
Professor Roy Taylor, Professor of Medicine and Metabolism at the University of Newcastle, was also interviewed as part of the report and said it was “appalling” that obesity rates were continuing to rise.
Later on in the BBC radio programme, Dr Alison Tedstone, National Director with responsibility of diet, nutrition and obesity in the obesity in the Health and Wellbeing Directorate of Public Health England (PHE), talked about how current dietary guidelines work and why they are not currently changing them.
She said that any decisions are “governed by the evidence” and they mainly take into account “robust” and “longer-term studies”.
However, Dr Tedstone did concede that the government “recognises that it’s not working” which is why the Childhood Obesity Strategy and the sugar tax on drinks have been introduced.
She concluded: “We need to go beyond information and education. We need to think of the structural drivers of diet.”

Red meat, processed meat, measuring colorectal and breast cancer risk
"Our epidemiological findings are supported by mechanistic data. Red and processed meat contain pro‐carcinogenic components, such as heterocyclic aromatic amines (HAA), polycyclic aromatic hydrocarbons (PAHs) resulting from meat processing or preparation (such as cooking at high‐temperature), nitrites (used as additives) and induces N‐nitroso compounds (NOCs) formation in the digestive tract.40-44 These chemicals may exert a pro‐carcinogenic effect through direct DNA damage and have been associated with mammary tumor development in animal7, 9, 41 and human8, 10, 45 studies.13, 46, 47 Most importantly, red meat contains high levels of heme iron, which may contribute to initiate carcinogenesis via several mechanisms, including the production of genotoxic free radicals, NOCs or through lipid peroxidation.5, 48-50"

Les perles de la nutrition officielle: diabète
3- Je suis diabétique. Est-ce que je peux manger du chocolat noir?
Réponse
Oui, tout à fait, car ce n’est qu’une question de quantité. Vingt grammes de chocolat noir à 70 % de cacao (ou 2 carrés) contiennent 5 g de sucre, soit 1 c. à thé. Une personne diabétique peut ajouter un peu de sucre dans son menu pourvu que l’aliment sucré soit consommé avec des aliments riches en protéines et en fibres lors d’un repas. Donc, prendre de 2 à 3 carrés de chocolat noir par jour ne devrait pas déstabiliser le taux de sucre d’une personne diabétique, dans la mesure où l’on n’additionne pas d’autres aliments sucrés au même repas.
Commentaire: l'astuce est de dire sucré ("où l’on n’additionne pas d’autres aliments sucrés au même repas.") au lieu de glucide. Si vous ajoutez du pain c'est quoi? 80% de glucides. Donc il est parfaitement inapproprié chez un DT2 de manger du chocolat. Par contre le cacao pur et les fèves de cacao sont exellents. Au contraire une telle prise va entrainer un pic de glycémie et d'insuline. C'est à dire un stockage puissant des calories excédentaires quelles qu'elles soient.
