Eagle Creek

Last weekend, I went on a 3-day backpacking trip with some friends. We endured rain, snow, difficult river crossings and a vicious mouse attack, but managed to have a good time nevertheless. Here are a few pictures:Punchbowl fallsTunnel fallsBasalt cliffsApparently mice like chees...

Vaccines

I am a label reader. Whenever I'm thinking about buying food in a box, which is rare, I typically read the whole label to look for sinister ingredients. So when I got a booster vaccine for tetanus last week, naturally I asked for the product information.Along with a nice dose of tetanus and diphtheria toxoids, my medial deltoid received 0.28 mg of aluminum, up to 0.3 micrograms of mercury, and up to 100 micrograms of "residual formaldehyde". I got the vaccine because I like being able to chew, but I wasn't able to lift my...

Exercise Didn't Keep Us From Getting Fat

One of the surprising things I noticed when I was poring over data from the NHANES survey (US CDC National Health and Nutrition Examination Survey) from 1975 to 2006 is that the number of inactive people has diminished in that same time period from 50% to 24%. This is shocking to most people. We have this romanticized idea that in the 1970s people were more active, as if everyone chopped wood and walked 15 miles to work in the morning. The reality is, there were office jobs, housewives and cars without the large numbers...

California "Raw" Almonds

I bought about a pound of almonds yesterday for a backpacking trip I'll be doing this weekend. I like to soak raw almonds, then lightly toast them. It sweetens them and breaks down some of their anti-nutrients. When I arrived at the grocery store, the only raw almonds they had were from California. I prefer to buy domestic products when I can, but in case you haven't heard, "raw" almonds from California are no longer raw. They are required to be sterilized using steam or antiseptic gases, despite their relative safety...

Real Food VII: Lentils

Lentils are a healthy food that comes with a few caveats. They have more protein and less carbohydrate than any other legume besides soybeans and peanuts, and they contain a remarkable array of vitamins and minerals, particularly B vitamins. One cup delivers 90% of your RDA of folate, so between lentils and liver there's no need for those sketchy prenatal vitamins. Lentils must be properly prepared to be digestible and nutritious! I can't...

US Fructose Consumption Trends

As you may have noticed, I suspect fructose is involved in overweight and other health problems. It seems to have adverse effects on fat deposition in the liver and insulin sensitivity that could be related to its association with weight gain. I looked through USDA estimated per capita consumption of different sweeteners to get an idea of how fructose consumption has changed in the US in the time since adult obesity rates have doubled....

Lessons From the Pima Indians

At 38% and climbing in 2006, the Pima indians (Akimel O'odham) of Arizona have the highest rate of diabetes of any population in the world. They also have staggering rates of obesity (~70%) and hypertension. Things were very different for them before 1539, when the Spanish first made contact. They lived on an agricultural diet of beans, corn and squash, with wild fish, game meat and plants. As with most native people, they were thin...

Your Gut Talks to Your Brain

I've been reading through some papers on a gut-brain connection that regulates food intake and blood nutrient balance. I've learned some interesting things.First of all, when fat hits your small intestine (especially long-chain fatty acids), it sends a message to the brainstem via the vagus nerve. This rapidly inhibits eating behavior.The hypothalamus can also inhibit glucose production by the liver in response to fat in the bloodstream, by sending it signals via the vagus nerve.A recent paper that got me interested in...

Diabetes and Your Small Intestine

In the last post, I introduced you to the remarkable antidiabetic effect of gastric bypass surgery. It rapidly reverses diabetes in 83% of patients, and it seems to be due to bypassing the upper small intestine specifically, rather than caloric restriction. This points to a special role of the upper small intestine in regulating food metabolism. I told you I was going to look into the mechanism of why this effect happens, and here's the short answer:It's complicated and no one understands it completely. Now for the long...

The Miracle Diabetes Cure You Don't Know About

What would you say if I told you there's a cure for type II diabetes that's effective in 83% of people, extremely rapid, and requires no lifestyle changes? Would you think I was crazy? Well maybe I am, but the cure exists nevertheless. All it requires is a little intestinal mutilation. It's called gastric bypass surgery. It's an anti-obesity surgery where the digestive tract is re-routed, bypassing 95% of the stomach as well as the duodenum and jejunum, which are parts of the upper small intestine. The effect was first...

Cob

I've been thinking a lot about natural building lately. Here in the US, we are practically forced into occupying homes that are expensive and destructive to the environment. I met a woman last weekend who lives in a yurt and has an outdoor composting toilet. She paid $3,000 for the yurt, making it a dignified way to live on a low income. She's worried because what she's doing on her own property is illegal. She's living in a safe,...

Real Food VI: Liver

Liver was a highly regarded food among many hunter-gatherer and traditional agricultural societies. It's not surprising once you realize it's quite literally the most nutritious food in the world. It's because the liver is a storage depot, into which important nutrients are deposited in case of later need. A modest 4-oz serving of calf's liver contains 690% of your RDA of B12, 610% of preformed vitamin A, 215% of folate, 129% of B2,...
