Some thoughts on the essentiality of dietary carbohydrates.

I didn't know that there's a watch strap called Essentiality. I do, now.

This is a book-marking post for thoughts I had in https://www.facebook.com/TheFatEmperor/posts/1442430506020812.

"The human body does not need carbohydrates from an external food source, because it is capable of very precisely and correctly assembling its own amounts of glucose that is needed in very small amounts for auxiliary and specialized functions." - Igor Butorski.

1) It's not very precise. See http://nigeepoo.blogspot.co.uk/2012/04/how-eating-sugar-starch-can-lower-your.html

2) It's not enough to fuel high-intensity exercise. See http://nigeepoo.blogspot.co.uk/2011/02/funny-turns-what-they-arent-and-what.html

3) Using the above argument, the human body does not need saturated fats & monounsaturated fats from an external food source, because it is capable of very precisely and correctly assembling its own amounts of saturated fats & monounsaturated fats (out of carbohydrate) that are needed in very small amounts for auxiliary and specialized functions.

If we only consumed Essential Fatty Acids, Essential Amino Acids, Vitamins, Minerals, Fibre/Fiber, Water & Anutrients, there wouldn't be much to eat. Also, there wouldn't be a source of chemical energy to generate heat energy & mechanical energy. That's what dietary carbohydrates & fats are for.

Respiratory Exchange Ratio/Respiratory Quotient (RER/RQ) varies with carbohydrate & fat intake, as the body preferentially oxidises the fuel that's most readily available.

RER/RQ varies with Exercise Intensity.
Low-intensity exercise results in mostly fats being oxidised.
High-intensity exercise results in mostly carbohydrates being oxidised.
Medium-intensity exercise results in a mixture of fats & carbohydrates being oxidised.

The Comfy Chair?

Because nobody expects...


I'm writing this post lounging like a lounge-lizard on a comfy three-seater sofa. When I'm driving from A to B, I'm sitting in a comfy chair. Basically, I have a cushy life. I go for a walk in the evenings and I go to many music events, but as I'm (a bit of) an information junkie, I spend many happy hours on-line, lounging on my sofa. My bad.

Thanks to technology and energy, many of us have labour-saving devices and horseless carriages. Therefore, many of us don't burn much energy from doing hard physical work and from having to walk everywhere.

Therefore, to maintain energy balance, many of us have to eat little food energy to maintain a reasonable weight and body composition. To get all of the vitamins*, minerals, fibre/fiber etc required for good health from little food energy requires the consumption of foods with high nutrient densities. You know where this is going, don't you?

*Except for Vitamin D, which requires sensible sun exposure between the end of March and the end of September when your shadow is shorter than you are.

If you enjoy irony, see What Did You Expect? Coca-Cola's Newest Anti-Obesity Ad Blames Chairs, Not Coke.

P.S. According to the BBC TV series "QI", the Spanish Inquisition gave thirty days notice of their arrival. Therefore, according to "QI", everybody expected the Spanish Inquisition!

P.P.S. As a cushy life results in muscles burning carbohydrate at a low rate, sedentary people are better-off eating less carbohydrates. See 10 Rules New Low-Carb Dieters Should Follow.

PPP - another bijou rant-ette.

Blame it on the hot weather and screaming kids! :-D

PPP stands for Piss Poor Parenting.

Why, oh why, oh why do parents allow children to dictate their own diets? As if children know what's good for them! At an event I attended recently, "Johnny*" was given a plate of chicken drummers (mechanically-recovered chicken formed into the approximate shape of chicken drumsticks and coated with breadcrumbs) and oven chips. I asked Johnny if he would like a beefburger, sausage or pork steak. He replied. "I don't like them". He only wanted manufactured shite. Seriously, WTF?

When I was a lad, I was given the same food as my parents. If I didn't eat it, I went without. I ate it!
Nowadays, "children's menus" in restaurants (I'm being quite generous in the use of the word restaurant) consist of lots of manufactured shite that children like. Unlike veggies & fruit, this shite contains very little fibre/fiber or magnesium.

Is it any wonder that childhood constipation is a problem? Why are children being given PEG or even Lactulose, when there's a much better solution - Epsom Salts (which contains magnesium). The gut needs magnesium to function properly. See You're free, and a testimonial.

The brain needs magnesium to remain cool, calm and collected i.e. function properly. The brain also needs DHA and Vitamin D3 to function properly. Many kids don't like oily fish so they won't/don't eat it. It's not rocket science to purée some wild red salmon with some Bolognese/Sweet chilli/w.h.y. sauce so that they won't notice it. Many kids play indoors or are smothered in sunblock when they do go outdoors. Is it any wonder that childhood ADD/ADHD is much more common? Medication and psychotherapy? Seriously, WTF?

When I was a lad, there were a couple of show-offs in my class at school, but nobody behaved like "Jimmy*" (physically and mentally hyperactive with bad behaviour, screaming and shouting). Johnny was also badly behaved, but not as bad as Jimmy. The parents at the event seemed content that, every day, their children had to be given "uppers" (e.g. Ritalin) to help them concentrate during the day and "downers" to help them sleep at night. Seriously, WTF?

I will now take a deep breath and count to twenty. There, that's better!

*Names changed.

How eating sugar & starch can lower your insulin needs.

This is a bookmarking post. Jason Sandeman is a chef who has a couple of web-sites at Well Done Chef! and Jason Sandeman — Real Food For Your Life. He has Latent Autoimmune Diabetes of Adulthood (LADA), which has resulted in a total loss of his pancreatic beta cells which means that he has to inject insulin.

Now, it's generally believed in low-carb circles (and by myself) that people with Type 1 Diabetes Mellitus (T1DM) should minimise their intake of sugary & starchy carbohydrates as these promote wild fluctuations in blood glucose. See The problem with Diabetes.

Jason wrote the following comment on Richard Nikoley's blog. The relevant part is as follows:-
"Even more weird – now that I have introduced the starches into the diet – I have actually got better control now. I thought my insulin needs would go up – but they haven’t. They’ve gone down."

To which I replied:-"How about this for an explanation? You now have a well-controlled glucose input to your circulation via diet, which has suppressed the poorly-controlled glucose input to your circulation via hepatic glucose production."

Hepatic glucose production (HGP) is increased by Glucagon, Cortisol & Adrenaline/Epinephrine. These are secreted as blood glucose level falls below certain values in order to keep our brains alive. See Blood Glucose, Insulin & Diabetes.

As keeping our brains alive is rather important (!), the mechanism is fairly crude in operation and blood glucose can overshoot in a positive direction, as a bit of glycation is less harmful than brain death. See "Funny turns": What they aren't and what they might be. Hyperglycaemia requires insulin to lower blood glucose back to the normal range.

Therefore, eating some (but not too much) sugar & starch can result in lower blood glucose level and lower insulin secretion. Eating fibre/fiber (a carbohydrate) is also good for keeping blood glucose low, as only just mentioned in Fiber and Insulin Sensitivity. Ain't the human body weird?

Fiber and Insulin Sensitivity.

Bluddy Americans. It's Fibre! But anyway....

Stabby the Raccoon posted the following study in a comment on CarbSane's blog. I thought that it was so interesting that I am linking to it here.

Fiber and Insulin Sensitivity.

This study has built-in cognitive dissonance.

The first Fig. suggests that cereal fibre is associated with a much lower RR for Type 2 Diabetes Mellitus (T2DM) and that fruit & veggie fibre aren't.

Schulze et al. 2007: Cereal Fiber RR = 0.6 - 0.7. Fruit Fiber RR = 0.9 - 1.05. Vegetable Fiber RR = 0.95 - 1.15 approx.

The next table suggests otherwise.

Andersson et al., 2007: Whole grain diet contained 112 g/d of whole grain, 18 g fiber. No effect of whole grains on insulin sensitivity.

Ebeling et al., 1988: 5 g/d granulated guar. No effect on insulin sensitivity.

Johnston et al., 2010: Resistant starch supplement -40g/d. Improved insulin sensitivity with resistant starch.

Landin et al., 1992: 30 g/d granulated guar, given in 3-10 g doses. Improved insulin sensitivity with guar diet.

Maki et al., 2011: High-resistant starch diet- 30 g/d, Low-resistant starch diet- 15 g/d. Improved insulin sensitivity with both resistant starch diets, but effect only reached statistical significance for men.

Nilsson et al., 2008: White bread enriched with barley fiber and 8g resistant starch, Barley kernel based bread. Improved glucose tolerance with resistant starch.

Pouteau et al., 2010: 28 g/d acetogenic fibers (acacia gum and pectin). No effect on insulin sensitivity.

Robertson et al., 2003: High-resistant starch diet- 60 g/d. Improved insulin sensitivity with resistant starch.

Weickert et al., 2006: Fiber-enriched with 31.2 g insoluble fiber. Improved insulin sensitivity with increased insoluble fiber.

In conclusion, the resistant starches found in high-amylose rices such as Basmati, refrigerated boiled rice & boiled potatoes, also rye & barley breads are beneficial in terms of reducing your RR for T2DM. Watch out, though. Too much dietary resistant starch can cause colic, flatulence & diarrhoea if your intestinal bacteria are knackered. You want fermentation to short-chain fatty acids to occur, not osmotic laxation! See Genetics of Food Intolerance.
