【推荐1】Preventing heart disease is a topic I think about all the time, given my family history of heart disease. So last summer, I travelled to Bolivia. The natives, called the Tsimane, were reported to have the healthiest hearts in the world. I wanted to learn what they could teach me about preventing heart disease.

Getting to the Tsimane wasn't easy. They lived in small family groups of about 60 people along river banks. We finally found one of the villages at sunset. That night, we set up our tents in the middle of the village. Thatched huts surrounded us, with no electricity or modern conveniences.

At first, I thought they mainly got their calorics from meat. However, I found food such as rice and com made up nearly 70% of their diet. The food was not processed, lacking added sugars or salts.

During my stay there, I went hunting and fishing with the men and played soccer with the kids. I found the Tsimane were standing or walking nearly all of their waking hours. Men spent lots of time tracking animals. Fanning and gathering, mostly done by children and women, were all-day affairs.

I also got a clear idea of how they rested. As soon as the sun went down, people returned to their huts and went to sleep. And with the call of the cock in the morning, another day began.

The lifespan of the Tsimane is actually much shorter than those living in the US. Various factors, like animal attacks and infections, bring down the lifespan. But up until the day they die, they are often very healthy. While heart disease kills thousands of Americans every year and costs nearly a billion dollars a day, the Tsimane remind us that wealth doesn't necessarily buy health.

【推荐2】Migraine is a disease that has a number of symptoms (症状), including head pain that can stick around from four hours to several days. While migraines can happen partly because of genetic problems, attacks may happen by chance, set off by a cause in the environment.

One common cause is food, and some common dietary causes include alcohol, salt, sugar, chocolate, and caffeine. But there are many others, and scientists continue to identify more. Last year, for instance, a Brazilian study found that watermelons brought on a headache within minutes in about 30 percent of the participants.

Some new researches are looking at which foods and what kinds of diets can prevent or lessen migraines. A new study published last year by a team of researchers found that a diet higher in fish oils rather than vegetable oils helped people ease their headaches. In the study, those on a diet lower in vegetable oil and higher in fatty fish had a 30 to 40 percent reduction in total headache hours per day, serious headache hours per day, and overall headache days per month compared to the control group.

Tanya Kamka had suffered weekly migraines for most of her life. Then, in her 50s, she joined the NIH diet experiment and increased her intake of fish. After only a few months, “I haven’t had a migraine, not even a mild one, in over two years. ” she says.

For others, the solution comes from plants, not fish. A 60-year-old man joined a study on the food-migraine link and turned to a diet, which includes a lot of dark, leafy greens. After two months he was experiencing only one migraine a month instead of the 18 to 24 a month he’d suffered before.

Clearly, people with migraines react to food in very different ways. What works for one person may not work for another.
