It is going to be Heart month on PEI - the hope is to increase awareness.
Much of what you will hear is good and uselful but there is one central idea that the Heart and Stroke Foundation have got wrong. They still buy into the canard that fat makes you fat and that grains play a major part in a healthy diet.
The Fat makes you fat idea has been wonderful for the Food industry who have been able to sell us food that is officially "healthy" like this. Basically this is a sugar bar. Not just the sugar but the HFCS and the oatmeal itself - in reality such a bar should have the kind of health warning that cigarettes have.
How about this?
A typical Low Fat Yoghurt - Healthy right?
No! Sounds like a healthy option…”low fat yogurt”. But no. 33 grams of carbs, 27 grams of sugar (most of which is dreaded high fructose corn syrup), and only 5 grams of protein. That is, essentially, a recipe for fat storage despite the fact it’s “low fat”.
Well here is the science from Dr Staffan Lindeberg whose book - Food and Western Disease is the complete guide for all of us who want to know the truth.
"Restriction of dietary fat, in particular saturated fat, has been promoted since the mid 20th century in order mainly to prevent atherosclerotic disease and overweight, which became increasingly common during the first half of the century [1]. The benefits of dietary fiber were proclaimed around 1970 although proponents of ’coarse food’ have been heard long before. The idea largely emerged from belief systems concerning disturbed bowel function, bloating and ”autointoxication” in the 19th and early 20th century [2]. The popularity of the hypothesis increased dramatically around 1970 when Hugh Trowell, an internist, and Denis Burkitt, a surgeon, launched the idea that dietary fiber would prevent certain age-related, degenerative diseases [3, 4]. For more than 20 years, working at clinics in Kenya and Uganda, both men noted that Western diseases were largely non-existent among the native population. Burkitt, above all, had the greatest success positing the fiber hypothesis. He was a good speaker and also the first to characterize the type of lymphoma that later carried his name, which gave extra weight to his credibility.
The notion that fat is unhealthy has essentially been based on epidemiological studies, in particular the Seven Countries Study [5]. In this study, 12,095 men aged 40-59 were followed for 10 years starting around 1960. The incidence of ischemic heart disease was positively associated with total and saturated fat intakes, which, respectively, explained 25% and 70% of the disease rates among the study populations.
However, despite widespread consensus among nutrition experts today, there is no solid evidence of fat enrichment or fiber depletion being important causes of Western disease.
In the Seven Countries Study, US men had more than 100-fold higher incidence of ischemic heart disease than Cretan men despite identical fat intake, 40 percent of dietary energy (E%) [5]. In one large randomized controlled study of nearly 49,000 US women, the Women’s Health Initiative Dietary Modification Trial, no beneficial effect was seen on cardiovascular disease, cancer or total mortality during 8 years’ follow-up by a low-fat, high fiber diet [6].
For the 3.4% of women with diagnosed cardiovascular disease at the start of the trial, a statistically significant increased risk of worsening of cardiovascular disease was seen in the intervention group (relative risk 1.26; 95% confidence interval 1.03-1.54). Diet changes at 6 years after study start (evaluated from food frequency questionnaires), in the intervention group as compared with the control group, were as follows: fruit/vegetables +30%, grains +11%, fiber +16%, total fat –8%, trans fat –22%, saturated fat –23%, monounsaturated fat –23%, carbohydrate +18%.
The intervention and control groups differed with regard to intensity of dietary education but not with regard to type of dietary advice.
In contrast to these disappointing findings, in two other studies, subjects with impaired glucose tolerance had a lower risk of being diagnosed with diabetes during 3 years after advice to eat a low-fat, high-fiber diet and to increase their physical activity [7, 8].
The study design precludes any opinion about the independent roles of diet and exercise. In a meta-analysis of randomized controlled trials in humans, restriction of total and saturated fat apparently had no positive overall effect on total mortality or cardiovascular disease [9]. However, in trials with at least 2 years’ follow-up, a 24% reduction of premature death or cardiovascular events was seen (relative risk 0.76; 95% confidence interval 0.65-0.90), although no effect on total mortality was found.
Be careful out there - really do your research. Remember it is normal for the establishment to be slow and to hold onto ideas that are wrong. Remember the world was once flat. Remember disease was spread by miasma. Remember that there was never going to be another war after 1918. Global warming is a hoax right? Peak Oil will never happen. Pesticides are safe.
What I am reporting to you from people like Lindeberg is well known and has been so for years but is seen as being outside the pale - just as that smoking was bad for you. And by the way, ask yourself who owns most of Big Food today?
This sums up the context for me:
As nutrition scientists try to find the ideal for the future, others look to history and evolution for answers. One way to put our diet in perspective is to imagine the face of a clock with 24 hours on it. Each hour represents 100,000 years that humans have been on the Earth.
On this clock, the advent of agriculture and refined grains would have appeared at about 11:54 p.m. (23 hours and 54 minutes into the day). Before that, humans were hunters and gatherers, eating animals and plants off the land. Agriculture allowed for the mass production of crops such as wheat and corn, and refineries transformed whole grains into refined flour and created processed sugar.
Some, like Phinney, would argue that we haven't evolved to adapt to a diet of refined foods and mass agriculture — and that maybe we shouldn't try.
