hachiya··on Full-fat-dairy for cardiovascular health
This is not in conflict with your point above that nutrients are removed along with the fat in processed milk, that are then readded (e.g. vitamins A and D), but it's important to realize that those single digit percentages refer to fat in terms of weight.

Ignoring the water content of milk, and looking solely at the caloric percentages, the fat ratio is:

Whole Milk: 48% fat

2% Milk: 33% fat

Skim milk: 5% fat

Referring to fat content of foods and beverages by percent of weight is generally not a useful measure for nutritional purposes. By that thinking, if one were to drink a few glasses of water and then eat 1/2 a pound of ice cream, they could claim they had a low fat meal, because the total grams of fat from the ice cream is small compared to the total water weight of the two items they consumed.

hachiya··on Placebos Are Getting More Effective. Drugmakers Are Desperate to Know Why.
I would speculate that when placebos appear to work, it is primarily because they don't do anything, besides possibly providing some increased hope to the patient, allowing the body to work without the "side" effects of drugs. The human body naturally tries to heal itself to the best of its ability.

Here's a very interesting example of placebos being administered on a routine basis, for years.

  Natural Hygiene, as it is today, can be traced back to Dr Isaac
  Jennings (of Oberlin, Ohio, USA) who, after practising medicine for 20
  years, began to ask questions when, during a fever outbreak in the
  summer of 1815, a patient who rested, drank water and did nothing,
  recovered in absolute record time compared to patients who had been
  medicated. Based on this, Dr Jennings noted similar results with many
  other patients.

  He then went on to treat many patients with what must have been one
  of the first placebo (dummy pill) treatments. In 1822 he gave up
  medical pills, plasters, powders and potions and treated patients with
  pills made from bread and vegetable-coloured water for the next 20
  years. This he only did to keep the patients’ confidence in him. He
  would then advise his patients to correct their lifestyle and diet to
  a more natural approach. He then practised for a further 20 years the
  "do nothing mode of treating disease." He wrote three books, "Medicine
  Reform" (1847), "Philosophy of Human Life" (1852) and "Tree of Life"
  (1867).

  Natural hygiene was often referred to at this stage as Orthopathy
  meaning TRUE or RIGHT AFFECTION or BEHAVIOUR.

  Dr Jennings had a great influence upon Dr R T Trall, who went on to
  do more for the hygiene movement than any man, next to Dr Herbert
  Shelton.

I've read this account on other sites as well. The Jennings story can be verified by other sources online. His deliberate use of placebo for so many years is fascinating.

hachiya··on The clothes don't make the man (boy)
The kids "somewhere in between" "strive to become popular and have all sorts of angst"?

That's a pretty big claim for ALL the kids who are neither nerds nor popular. I speculate that a great deal of those kids don't obsess about highschool drama, don't "strive to become popular", and don't end up with "all sorts of angst."

Also, one could safely consider that perhaps the author of a lengthy article about middle school and high school popularity has some undealt-with angst issues...

I'm just saying that I'd be careful about making sweeping generalizations, unless you want to come across as harboring that angst yourself.

hachiya··on The clothes don't make the man (boy)
True, it seems half the California male highschoolers go for the homosexual look of wearing girls' pants these days. Some influence of "emo" music bands, perhaps. Not sure how trendy baggy pants are any more.

Of course, my claimed observation of "half" could be way off the mark.

hachiya··on The clothes don't make the man (boy)
I've heard this about European countries, such as Italy and Spain, many times over the years.

If it is indeed true in general, I wonder why. Better family structure leading to less insecurity among kids, so they don't take out as many of their issues on classmates later in life? Different kinds of TV shows molding their impressionable minds when young? There are likely a variety of factors, but I haven't come across an explanation.

Given that most people would care if even a stranger were assaulted and pushed to the ground, perhaps the clerk reasonably assumed you didn't care because it was a Catholic figure who was the target. In that case, he would be right in assuming YOU were intolerant - of Catholics.

Well, at least people around you must be tolerant of fat people.

hachiya··on Sugar: The Bitter Truth (UCSF lecture)

There is a counter system to eating foods that are sweet, provided foods are eaten in their whole, fresh, and ripe state.

Try to overeat on fruit - it's imposssible. You'll feel full and be tired of "sweet" long before you could ever overeat on it. Fiber and sufficient blood sugar have a way of telling one when they have been satiated.

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
First you speculate that salt was not easy to find:

  > The fact that we like it so much, as with sweets, 
  > suggests that it was hard to find.
Then you claim salt was abundant:

  > With salt it's possible to eat too much: that makes us
  > feel bad. That suggests that salt was abundant, 
  > otherwise we wouldn't need the counter system.
Which is it - according to your speculative theories, was salt abundant or not?

Your speculation on sweet being difficult to find is also nothing more than (poor) speculation. The link I provided above is just one example showing that fruit WAS abundant, as regardless of what those creatures were, fruit was easily accessible.

It amazes me how much people use "evolutionary theories" to speculate about just about anything to reach just about any conclusion.

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
Why would the fact that we like things that taste sweet indicate that they were hard to find?

Our bodies run on sugar; sources of sugar, such as fruits and starches were not hard to find.

Availability and use of fruit in our diet long ago is hardly anything new. It certainly was not hard to find.

  Research Yields Surprises about Early Human Diets

  Teeth Show Fruit Was the Staple

  By Boyce Rensberger

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
2000+ calories of fruits and vegetables alone will supply more than enough of one's daily sodium needs.

We need sodium. We don't need rock salt.

CRON-O-Meter (Linux/Win/Mac) and similar software/sites (e.g. fitday.com) will demonstrate this for anyone who wants to see how the numbers fall into place for any of the nutrients.

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
A natural form of MSG is found in one popular variety of edible seaweed: kombu.

Interestingly, some canned beans, e.g. Eden Organic (unsalted), come with kombu in the can.

All the debate over things like artificial/alternatives sweeteners and MSG seem like a severe case of not seeing the forest for the trees. The issue of which sweetener to use is not so big as how much of any of the sweeteners. And for those who eat a diet of only whole foods, the answer is even easier: none.

The controversy over issues like these has the general public all worried about things they don't need to worry about so much, instead of being concerned about things they really should be, e.g. what foods make up the diet and their nutrient density. Worrying about MSG in my junk food, organic vs. conventional pizza, or HFCS vs. cane sugar soda, is not likely to have much benefit if these items make a regular appearance in my diet.

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
Vitamin D is a fat soluble vitamin, like Vitamins A, E, and K. It does accumulate in the fat tissue. An excess of Vitamin D is not simply disposed of in the urine, like Vitamin C or the B-complex.

Interestingly, although it is now evident that Vitamin D insufficiency and deficiency is higher in the general population than previously realized, it is often worse in those with higher levels of fat in the body.

  "CONCLUSIONS: Obesity-associated vitamin D insufficiency is likely due to the decreased bioavailability of vitamin D(3) from cutaneous and dietary sources because of its deposition in body fat compartments."
above from Am J Clin Nutr. 2000 Sep;72(3):690-3. Decreased bioavailability of vitamin D in obesity.

Vitamin D toxemia can occur. One of the more common symptoms is nausea, and if the toxemia persists, calcification of soft tissue and formation of kidney stones can result. Vitamin D is needed for proper intestinal absorption of calcium, so excess Vitamin D can throw off proper mineral balances in the body.

Likelihood of toxemia is rare for Vitamin D, however.

Consider that a healthy individual can obtain 10,000 IU or more of Vitamin D produced by their own skin from being exposed to the sun for 20 to 30 minutes. The amount of Vitamin D in a standard multivitamin supplement is rarely more than the current US RDA, which is only 400 IU. So even people taking higher dose Vitamin D supplements of, say 5000 IU, are not really mega-dosing/"going Linus Pauling" with their Vit. D.

Also, that current RDA of 400 IU is now considered by many scientists and health professionals to be too low. It may simply be the minimum amount needed to prevent rickets (known in adults as osteomalacia). Now it is known that it is needed for more than just bone development and maintenance, as Vitamin D receptors have been found throughout the body; some reports say virtually everywhere.

Reading through the information at http://vitamindcouncil.org , it appears that to achieve what is now considered an optimal Vitamin D level in the body, people generally need more sun and/or supplementation.

In the news within the last year or so, a study reported that even 50% of Hawaiians were low in Vitamin D. In modern society, I guess that walking from the car to the office daily just doesn't cut it for sun exposure ;)

hachiya··on Sugar: The Bitter Truth (UCSF lecture)
Mostly good points. I think some comments are necessary on a few though:

Agave nectar and stevia as sugar substitutes are also not without controversy. I find it easiest to get my sugar from whole, ripe, and fresh fruit. Once sufficient fruits are eaten on a regular basis, the desire for refined sugary products disappears.

Stevia: Potential problems, including cancer, reproductive issues, and interference with energy metabolishm: This article is a good start: http://www.cspinet.org/nah/4_00/stevia.html

Remmeber, stevia is an herb. Treating an herb as a food, i.e. the amount used in order to function as a replacement for sugar, is not necessarily a wise idea. Would you use ginkgo balboa or St. John's Wort as a food? Also, most people don't use actual stevia leaves, so it is still a refined product. Moving from refined sugar cane to refined herbs is not necessarily a good move. Developing a taste preference for whole fresh fruits over refined sugar products would serve our interests far better in the long run.

Agave nectar/syrup: this one certainly has a lot of hype behind it, but mostly it appears to be marketing tactics. Just think about the fact that excess fructose can raise general risk markers (triglycerides and VLDL) and has been linked to increased risk for insulin resistance, diabetes, and cardiovascular disease.

High fructose corn syrup is 55% fructose.

Agave syrup is 70-90% fructose.

So if you think too much fructose is bad, you must think HFCS is better than agave syrup.

Lastly, the recommendation for cyanocobalamin to be shunned in favor of hydroxy seems a bit off. The known highest active form of B12 for humans is methylcobalamin. Hydroxy is more efficiently converted than cyano, but methyl has the general current consensus, in the medical research world, of being best. Fortunately, B12 supplements of the methyl form are easily obtainable (e.g. Jarrow is a brand with 1000 and 5000 mcg sublinguals cheaply available, and there are a number of other brands). I've never even heard of a hydroxycobalamin tablet - only that it is the standard form used for shots in some countries. It is important to realize that most US and European doctors are still behind the times and administer cyanocobalamin (in some European countries, hydroxy is used, but this is still not as preferable as methylcobalamin) for B12 shots when a patient is found to have a problem with B12 levels. However, shots are almost never needed anyway, as the diffusion process of sublingual tablets is so great that they are just as effective as shots.
