Nutritionism and the glycemic index

3-levels-of-glycemic-index

Let me begin by quoting a paragraph from Gyorgy Scrinis, a lecturer in food and nutrition politics and policy at the University of Melbourne. This is from a chapter called ‘Nutritionism and Functional Foods,’ which he contributed to the book The Philosophy of Food. Scrinis went on to publish an entire book on this subject, Nutritionism: The science & politics of dietary advice.

Just prior to the following paragraph, Scrinis has been discussing the dietary advice, from the 1960s to the 1990s, that it was better to eat margarine than butter. (Added emphasis in this and the following quotations is mine.)

The “mistake” of inadvertently promoting transfat-laden margarine is one of several mistakes, revisions, and backflips in scientific knowledge and dietary advice over the past century. Other cases include advice regarding dietary cholesterol, eggs, low-fat diets, and vitamin B. Yet these revisions do not seem to have tempered the sustained and confident discourse of precision and control that continues to pervade nutrition science, nor the willingness to translate limited and partial scientific insights into definitive population-wide dietary advice. I refer to this nutritional hubris as the myth of nutritional precision, as it involves an exaggerated representation of scientists’ understanding of the relationship between nutrients, foods, and the body and a failure to acknowledge the limits of the nutrient-level perspective. At the same time, the disagreements and uncertainties that exist within the scientific community with respect to particular nutritional theories tend to be concealed from, or misrepresented to, the lay public.

Jamais vu and the hippocampus as GPS

hippocampus-as-gps

I always thought the main function of the hippocampus was to convert short-term memory into long-term memory. It’s one of the first regions of the brain damaged by Alzheimer’s. If your spouse can’t remember something you discussed 20 minutes ago, you start to worry.

The hippocampus also plays an important role in spatial memory and navigation. That’s why you unfortunately hear of Alzheimer’s patients wandering away from home and not being able to find their way back.

A recent JAMA article, Nobel Prize Winners’ Research Relates to Brain Function and Neurodegenerative Diseases, describes the hippocamcus as our inner GPS. Place cells in the hippocampus (discovered in the 1970s) are associated with locations (even if you’re just thinking about a location), and grid cells (discovered in 2005) create triangular grids that function as a positioning system in space.

Together, place and grid cells allow animals to determine their position and to navigate through their surroundings much like an inner GPS.

Daylight saving time and heart attacks

Congress passes daylight savings bill1.6 billion people – almost a quarter of the world’s population – observe the biannual shifts between standard and daylight saving time. Does the loss of an hour’s sleep in the spring affect their health? According to a study published in The New England Journal of Medicine, there’s a statistically significant increase in the number of heart attacks (myocardial infarctions) in the week after we shift to daylight saving time.

Researchers in Sweden extracted statistics from 20 years worth of data on heart attacks. They compared the incidence of heart attacks during each day of the week after we change the clocks (both spring and fall) with the number of heart attacks two weeks prior to and two weeks after the time change.

There are always more heart attacks on Mondays, presumably connected to the stress of going back to work. But the number of Monday heart attacks was significantly lower following an extra hour of sleep in the fall. In fact, except for Fridays, the number of heart attacks was lower for the rest of the week. Following the loss of an hour’s sleep in the spring, heart attacks were up for the entire week, and the increase was especially significant on Tuesday.

Here’s the data displayed graphically.

Monday heart attacks and sleeping in on the weekend

These findings, of course, do not mean that losing an hour’s sleep causes a heart attack, but they do suggest that individuals who are vulnerable to heart problems might want to make the transition to daylight savings time gradual rather than abrupt. Read more

Chocolate has antioxidants but is that a good thing?

Chocolate antioxidants Valentine's dayChocolate is a perennial favorite as a health topic. Readers are eager to learn of medical research that justifies something they want to do anyway.

WebMD recently ran an article called “Is Chocolate the Next Super Food?” The excuse for this particular article was a study that found the antioxidant activity of dark chocolate was higher than that of various “super” fruits (blueberry, acai, cranberry, pomegranate).

The article’s very last paragraph did mention — very casually — that the number of calories and fat grams in a serving of dark chocolate exceeds those of fruit juice. There was nothing but praise, however, for the ability of the antioxidants in chocolate to fight free radicals. The wisdom of the widespread consumption of antioxidants has recently been questioned. Getting the word out on that subject may prove awkward for WebMD, a site littered with ads for antioxidant supplements.
