Sensationalist Science

A study published earlier this month found an association between individuals eating foods considered “acidic” and the risk of them developing Type 2 Diabetes (T2D).

We are currently in the midst of an obesity and T2D epidemic. We are constantly being told by Health Agencies about the importance of healthy eating as well as maintaining a healthy weight. Not to mention heaps of research telling us that eating certain foods will delay the onset of a variety of diseases.

The main aim of the study was to investigate if there is a link between the “acidity” of certain foods and the risk of developing T2D. This study included over 66,000 French women who were required to fill in a comprehensive diet-history questionnaire. They also had to provide a urine sample at the start and end of the study. The urine sample was used to test for the amount of acidic foods consumed through the diet and this was scored against a scale.

The women who had a higher urine acid score consumed meat, fish, cheese, bread, soft drinks anas well as artificially sweetened beverages. What the authors did was group these food groups together as being collectively responsible for a high urine acid score.  

What’s interesting about this is the authors never mention that meat is responsible for an increased risk of diabetes. Sadly however, the NHS has looked at this study and cherry-picked meat as a factor contributing to an increased risk of developing T2D.

Study Shows Bread and Potatoes Contribute to Obesity

A study published this week in the British Journal of Nutrition found that a diet high in bread and potatoes is contributing to general and central obesity in British Adults.

This study looked at analysing a 7 day weighed diet diary of individuals aged 19 to 64 years old, from all walks of life. What is interesting about this study is that it is the first study to positively link food items with a high dietary Glycaemic Index and a high Glycaemic Load to the obesity epidemic in Britain.

A food item’s Glycaemic Index (GI) score reflects the amount of carbohydrates present and the overall effect this item has on blood sugar levels. A low GI score means that the food item takes longer to be absorbed/digested thereby releasing energy in the form of glucose slowly into the body.  A food item’s Glycaemic Load (GL) takes into account how much each gram of carbohydrate in the food will raise blood sugar levels.

This study found that individuals who had a diet high in bread and potatoes but low in fruit and dairy were at a higher risk of general and central obesity, both in men and women.

Once again this is evidence that the current nutrition guidelines are ineffective in preventing obesity.  What is more worrying is that it is these very guidelines that may be making the situation worse as more and more people look to the EatWell plate for guidance on healthy eating.

The Evidence Keeps Mounting

Over the course of last week, two studies have been published once again showing the effectiveness of high-protein, low-carb diets. 

One of these studies carried out by the University of Sydney and found that humans will continue eating until they consumed enough protein. The study found that regardless of BMI or age, a person’s appetite was affected by the amount of protein they consumed in a meal and throughout the day. In short, people should be eating protein-based foods not only to get the necessary nutrition from it, but also to avoid over-eating. In another study carried out by the University of Missouri found that women consuming a high-protein, low-carb breakfast helped to regulate appetite throughout the day.

What both these studies show is that the current low-fat healthy eating mantra has no scientific foundation. Once again studies are showing that doing the opposite of this advice will lead to better overall appetite control.

These studies once again show the importance of following a low-carb, high-protein and moderate-fat approach to daily health – the Natural Ketosis way.

Hospital Food is Teaching Diabetics Bad Habits

Hospital food has a bad reputation, and is constantly under the scrutiny of the media – who regularly report on hospitals providing junk food to patients under their care, or the poor quality of hospital food.

Hospitals provide a range of menus to suit patient’s preferences; vegetarian, vegan, religious diets and medicinal diets are all catered for. Yet, despite this, there are no Low-Carb options for diabetic patients! Hospital food guidelines are expected to be updated in the near future, and while Natural Ketosis hopes these changes reflect low-carb options, the chances of this being the case is slim. The UK seems to be falling behind other European countries in terms of low-carb scientific thinking. You can read the implications of this here and here.

Currently the BDA and other UK establishments are following the ‘low-calorie’ option for diabetes management, where individuals are allowed to eat items such as low-fat, low-salt baked beans which contain 53.4g of sugar per can! If this wasn’t shocking enough, current hospital options for diabetics include scones, cakes, shredded wheat/cornflakes based breakfasts coupled with low-fat items which have sugar added to them once fat has been removed. Such advice is encouraging diabetics to follow a diet that is only aggravating their condition!

Here is the BDA press release of their involvement with the Food Hospital Standards Guidelines for summer 2014:

We remain hopeful that a low-carb option will be added for diabetics in hospital – however the chances of this becoming a reality in 2014 is slim.

The Science that is Not Getting Equal Media Attention

Every day new studies receive media coverage showing that diets based upon eating items found on the NHS approved ‘EatWell Plate’ can lower the risk of Coronary Heart Disease (CHD) and of developing Cardiovascular Disease (CVD).

Upon first glance, all looks well and good. However, when you closely inspect the type of trials that these assertions are based on, you will find they are not sound at all. The majority of these studies are carried out for a limited time (usually not more than 6 months), and are only testing the isolated effect of a certain food item on health. Hence, all these claims do not have as great an effect on health in day-to-day life.

However, the studies that are paving the way for better nutrition science are all coming up with the same answer: the current low-fat heart healthy mantra does not work in protecting the heart against disease onset, and yet these studies are most often overlooked by the media because of their ‘negative’ results!

The Woman’s Health Initiative Randomised Controlled Dietary Modification Trial (WHIRCDMT) was designed as one of biggest dietary trials of its kind to mainly test fatal and nonfatal CHD, fatal and nonfatal stroke, and CVD (composite of CHD and stroke).

In this trial, over 48,000 post-menopausal women took part. Participants were then divided into two groups; one group received an intensive behaviour modification course together with individual sessions designed to help reduce fat intake to 20% of total calories, in combination with increased vegetables, fruit and grain servings to 5-a-day. The control group received none of this structure, apart from diet-related education materials.

The conclusion?

To the astonishment of the researchers heading the study, after following the participants for an average of 8.1 years, the women who got the behaviour modification courses and the advice to lower their fat intake did not reduce their risk of CHD or CVD episodes.

Unfortunately, even after such a big trial confirming the fact that the current diet advice is not adequate; the UK health agencies are still advocating advice that has been scientifically proven to have no health benefits whatsoever.
