Vitamin A and the foods I eat (and don’t eat)

leave a comment »

Vitamin A (like vitamins D and E) is fat-soluble, which means the body retains it, unlike the water-soluble vitamins (C and B, for example), which are easily shed and must be replenished.

I came across an article this week about how vitamin A is not really very available from dark-green leafy vegetables, despite that being the universal recommendation as a source (other than animal sources: liver (beef, lamb, chicken) is high in vitamin A (and in fact polar-bear liver is has so much vitamin A that it can kill you if you eat it), as are eggs. But for those not eating animal-based foods, the universal recommendation is dark-green leafy vegetables.

The article described how a nutrition scientist found study after study showing that in actual fact people do not absorb much vitamin A at all from that food source.

I wish I could find the article, but at least I kept the bottom line: people not eating animal-based foods should take a vitamin A supplement. The recommended daily intake:

The supplement I found was 10,000 IU, so I plan to take one each Monday and one each Thursday: 20,000 IU per week, a little less than the 21,000 IU/week (3,000 IU/day) recommended, but of course I do get some from the foods I eat.

Vitamin A requires moderation: too little is bad and too much is bad.  I think 20,000 IU per week — perhaps with an occasional 30,000 IU week — will work.

One way I like kale

leave a comment »

Here’s a recipe I made (up) recently:

Thinly slice:

• cloves from one head of garlic
• 1″-2″ fresh ginger root, depending on how much you like ginger

Then prep the other veggies. For this I used my 4-qt All-Clad d3 Stainless sauté pan, since I was going to simmer it covered a while. I just added the ingredients to the pan as I prepped them, since I decided to cook this without oil (and thus without sautéing the first ingredients):

• 8-10 Crimini mushrooms, halved and then cut in slabs (or simply chopped coarsely)
• about 1/3 block of extra-firm tofu, diced
• 1 large red onion, chopped
• 1 good-sized bunch green curly kale, chopped
• 1 300g box frozen chopped spinach
• 1 cup no-salt-added vegetable broth
• 1/4 cup apple cider vinegar
• as much crushed red pepper as you like — I used 2-3 teaspoons
• about 2 tablespoons Tamari or soy sauce
• 2-3 tsp German mustard

Bring it to a simmer, add the garlic and ginger, cover, and simmer 40-50 minutes, stirring from time to time.

That has the the “Greens” part of my meals lately.

This video is from a report in the Washington Post. The report is worth reading (but resides behind a paywall). Watch the video.

Wielding a gun makes a shooter perceive others as wielding a gun, too

leave a comment »

This study might offer one reason why police officers shoot a person holding a cellphone or sandwich or some other innocuous object and later say that they thought he was holding a gun.

A study validates the finding. The full study is at the link. Here’s the summary:

Nearly a decade ago, cognitive psychologist Jessica Witt wondered if the mere act of wielding a firearm could bias someone to perceive another person as wielding one, too — and more importantly, if such a bias could be scientifically measured. A series of experiments later, Witt and her research team concluded, yes and yes. The team has recently published a new set of experiments further underscoring what they call the ‘gun embodiment effect’.

The report at the link is brief and is worth reading. As it notes:

The effects they saw in the lab were mercifully small. “But if you have this small effect, and put it on a national scale, and you talk about how many people have guns in this country, even these small effects are important,” Witt said. “For example, if 100 officers wielding guns interact with 10 unarmed people a day for 100 days, in these 100,000 interactions, our data suggest there were will be 1,000 misperceptions of an unarmed person as holding a gun.”

The Republican effort to destroy democracy (because they cannot otherwise hold power)

leave a comment »

Heather Cox Richardson has a post today that is well worth reading. It’s good enough you should read the whole thing, and note that after the post she includes links to the sources of her information.

I’ll quote only the last of the post:

. . . Second: There is a war underway for control of the Republican Party. While a losing incumbent president usually loses influence in the party, Trump intends to continue to call the shots. He wants to run again in 2024, or at least to anoint a successor, rather than letting the Republican National Committee pick a presidential candidate. There is a struggle going on to control the RNC and, as well, to figure out who gets control of the lists of supporters Trump has compiled. Trump also controls a lot of the party’s money, since he has been out front as its fundraiser without a break since he decided to run for office. He was the first president ever to file for reelection on the day of his inauguration, permitting him to hold “rallies” and to raise money throughout his presidency.

So Republican lawmakers are willing to swear loyalty to him, either because they want to attract his voters in future elections, or because they want access to the cash he can raise, or both. They no longer defend traditional policy positions; they defend Trump.

This loyalty requires contortions. In Georgia, the Republican Georgia Attorney General Chris Carr called the Texas lawsuit “constitutionally, legally and factually wrong.” But Georgia’s two senators, Republicans David Perdue and Kelly Loeffler, have backed it. The senators are facing a runoff election in January against Democrat challengers Jon Ossoff and the Reverend Raphael Warnock, and they need Trump’s support. So they are taking a stand against their own voters. So are nearly half of Georgia’s Republican congressional delegation, despite the fact that this position logically would overturn their own elections.

Third: Texas’s lawsuit and the Republican Party’s embrace of it is an unprecedented attempt to destroy the very foundation of our democracy. Since the 1980s, Republican leaders have managed to hold onto power by suppressing votes, promoting disinformation, gerrymandering states, gaming the Electoral College, and stacking the courts.

Now, so unpopular that even gaming the mechanics of our system is not enough, they have abandoned democracy itself.

Planet Java Hive, a favorite fragrance, and the Gillette Heritage version of the Edwin Jagger razor

leave a comment »

This is a CK-6 soap, and the fragrance is (to my nose) extremely nice: the coffee-honey combination works better than one would expect. The trusty Plisson from Paris felt very good on my face, and the Edwin Jagger design is a solid performer.
