Free will? It's just an illusion! How the Food Product Industry gets people to dance to their tune, part 3.

Cont'd from Free will? It's just an illusion! How the Food Product Industry gets people to dance to their tune, part 2.
 
Derren Brown shows how easy it is to manipulate your thoughts, by the use of subliminal images.


I may have mentioned it somewhere on this blog, but everyone is different. The reactions of the kids in the "I ate all your Halloween candy" video in the previous blog post varied from total melt-downs, through feigned deaths, through tears, to "That's all right!". Candy/sweets have different importance to different people and people's suggestibility varies from "Very easy to manipulate" to "Very hard to manipulate".

There's engineering of foods to be as moreish as possible. "The trouble is, they taste too good!" (Crunchy Nut Cornflakes), "Bet you can't eat just one!" (some savoury snack made from refined starch, salt & flavourings) and "Once you pop, you can't stop!" (Pringles). As Harry Hill once said "The problem with heroin is, it's rather moreish!" Although addiction to pure table sugar isn't a thing, addiction to hyperpalatable foods is a thing (which can be blocked by Naltrexone). See Food cravings engineered by industry and Sugar addiction: pushing the drug-sugar analogy to the limit.

Then there's the incessant marketing, including sponsorships, product placements, celebrity endorsements, cartoon characters on packaging to appeal to kids etc. See The Money Spent Selling Sugar to Americans Is Staggering and It’s Not Your Imagination: Celebrities Hawk Pretty Much Only Junk Food.

Then there's the bribery lobbying of government to:-
1. Water-down Dietary Guidelines so that crap-in-a-bag/box/bottle (CIAB) meets them. As people get fatter and fatter, the Guidelines and government get the blame.
2. Subsidise the ingredients of CIAB so that it's cheaper than produce.

Then there's corruption of science e.g. getting doctors to advertise cigarettes years ago. Organisations with vested interests are created, to promulgate conflicting dietary information. Is it any wonder that the public distrust science and scientists?

Edward Bernays' manipulation techniques have worked exceedingly well. If you're too fat and someone says to you "Nobody made you over-consume that crap", point out the above.

What can you do? You can't sue Food Product manufacturers, as their products don't immediately harm you. See How Ultra-Processed Foods Are Killing Us. Hit them where it hurts i.e. in their bank accounts, by eschewing CIAB and basing your diet on whole, minimally-refined animal and vegetable produce. CIAB should be treat foods, not staple foods.

Finally, here's a nice video on how to form good habits for life.

Cont'd from Free will? It's just an illusion! How the Food Product Industry gets people to dance to their tune, part 1.

Remember the video "YouTube Challenge - I Told My Kids I Ate All Their Halloween Candy 2015"?


Some of those kids reacted as if their life had just come to an end!

Disclaimer: I don't know anything about psychotherapy, so I don't know how accurate the information is in Hypoglycemia and Neurosis.

Please don't pacify crying babies/toddlers/children with sugary crap.

Start of clarification.
I've noticed some confusion over the term "Crap-in-a-bag/box/bottle" (CIAB). My previous post received the following comment, which I'll annotate.
"Is highly processed the problem? Yes.
Tinned tomatoes are processed, what's wrong with including those in your diet. Nothing, other than the fact that they're too salty for me if they're tinned in brine.
What about low sugar baked beans? Nothing, other than the fact that they're too salty for me.
What's wrong with a burger if all it is, is minced beef? Nothing.
Other processed food:
Smoked mackerel Fine.
Frozen peas Fine.
Milled porridge oats Fine.
Parma ham Fine.
Cheese Fine.
Nitrate free bacon Fine.
Prunes Fine.
Almond butter Too calorie-dense & moreish for me.
Filtered milk Fine.
Low sugar jam Fine.
Roasted chestnuts Fine.
Haggis Fine. I think."

CIAB is stuff like French fries/chips, chips/crisps, "fast food", take-aways, pizzas, biscuits/cookies, chocolate, sweets/candy, sugar-sweetened beverages, sugary cereals etc.
End of clarification.

In How to lose weight and get slim by eating "fast food" for 180 days. I showed that it's possible to be healthy on a diet of fast food, if you have a plan and you stick to it. The vast majority of people who eat fast food don't have a plan!

Between the ages of 5 & 8, I spent my 12d/week (that's 5p/week, for those of you who are too young to remember £,s,d.) on sweets. Aniseed balls were 4 for 1d. I also ate French Fancies (small sponge cakes covered in fondant icing) and drank Corona Lemonade (~15% sugar content) at home.

How did I get such a ferocious sweet tooth? Here's the probable answer:- Farley's Rusks.

Look at the health-washing on the Heinz web-site.
"Farley’s Rusks have been loved by mums and babies for generations. Each rusk is lovingly baked using baby grade ingredients."

Let's take a look at the baby grade ingredients:-
"Wheat Flour, Sugar, Palm Oil, Raising Agents (Ammonium Carbonates), Calcium Carbonate, Emulsifier (Monoglycerides), Niacin, Iron, Thiamin, Riboflavin, Vitamin A, Vitamin D."

The first three ingredients are refined starch, refined sugar and refined fat. The refined sugar content is 29% by weight. Perfect food for a baby! The previous sentence may contain traces of sarcasm.

Why (LDL particle) size matters.

Having gone through the math(s) with several people, I thought I'd stick it in a blog post for posterity.
I know that this is a diagram of a chylomicron, but bear with me!

Cholesterol synthesised in the liver is exported in LDL particles. The more cholesterol that's synthesised, the more particles there need to be to carry it.

∴ LDL-P (particle number) ∝ LDL-C (total amount of cholesterol)

The particles are roughly spherical with a very thin wall (consisting of a phospholipid mono-layer, the yellow wiggly lines with a green end bit in the above diagram).

Volume of a sphere = 4/3 * π * r3, where r = half the diameter.

If there's a 10% reduction in LDL particle size, the volume reduces to 0.729, relative to the original size. Therefore, to carry the same amount of cholesterol requires 1/0.729 = 1.37 times more particles, which is a 37% increase in the number of LDL particles, relative to the original size.

∴ LDL-P (particle number) ∝ 1/LDLsize3

As it's LDL particle number that determines the infiltration of LDL cholesterol into the media of artery walls, it's advisable to keep cholesterol synthesis to a minimum by keeping fat intake to a reasonable level * (i.e. not Nutritional Ketosis level) and keeping LDL particle size to a maximum by keeping sugars & fast starches intake to a reasonable level*.

Before someone asks, what I mean by a reasonable level is a level that is burned by the body without having a chronic excess. An acute excess can be stored, provided that mean intake is less than mean burning.
How COULD I write a post about LDL-P and forget to include THIS?

Carbs, Carbs, Carbs, Carbs and Carbs.

Carbohydrates seem to get the blame for everything nowadays. "Carbohydrates made me fat". "Carbohydrates burned-out my pancreas". "Carbohydrates raised my blood glucose". "Carbohydrates raised my blood triglycerides". "Carbohydrates stole mer jerb!". O.K, I made the last one up!
If carbohydrates are responsible for all of these bad things, then how come a diet of only potatoes had the opposite effect? See 20 Potatoes a day.

Also, Blue Zone populations eat a diet with a high percentage of total energy (%E) from carbohydrates. See Low serum insulin in traditional Pacific Islanders--the Kitava Study and The Kitava Study. The Kitavans eat ~70%E from carbohydrates, ~20%E from fats and ~10%E from proteins. They don't eat a significant amount of Western crap-in-a-bag/box/bottle.

Maybe it has something to do with the type of carbohydrates and with what they're eaten. In A very-low-fat diet is not associated with improved lipoprotein profiles in men with a predominance of large, low-density lipoproteins , (emphasis, mine) "The very-low-fat, high-carbohydrate experimental diet was designed to supply less than 10% of energy from fat (2.7% saturated, 3.7% monounsaturated, and 2.6% polyunsaturated), with 75% from carbohydrate (with equal amounts of naturally occurring and added simple and complex carbohydrate) and 15% from protein." Simple carbohydrates are sugars.

The experimental diet which did bad things contained 37.5%E from sugars. I declare shenanigans!

1. There are simple carbs, there are simple carbs and there are simple carbs. In the previous post, the graph of plasma triglycerides after an OGTT showed that 100g of glucose had no significant effect on plasma triglycerides over a 6 hour period. If it had been 100g of fructose, there would have been a significant increase in plasma triglycerides. Galactose is taken-up by the liver and has minimal effect on blood glucose, but I don't know its effect on plasma triglycerides.

2. There are complex carbs, there are complex carbs and there are complex carbs. Overcooked starch is high in amylopectin which is highly-branched, which means that it hydrolyses rapidly into glucose which gives it a very high glycaemic index. Raw & refrigerated potato starches have very low glycaemic indices, due to the presence of amylose, or other resistant starches. Rice contains a mixture of starches which varies with rice type, cooking time and subsequent refrigeration.

3. There are oligosachharides e.g. FOS.

4. There are polysaccharides e.g. inulin.

5. There is soluble fibre/fiber e.g. cellulose.

Although overeating sugars containing fructose & starches that rapidly hydrolyse into glucose makes the liver fatty, overeating fats also makes the liver fatty. See Pathogenesis of type 2 diabetes: tracing the reverse route from cure to cause.

It's the chronic over-consumption of crap-in-a-bag/box/bottle (high in sugars and/or starches and/or fats), not just carbohydrates, that causes over-fatness and other health problems.
