ON the anniversary of Osama bin Laden’s death last week,Pakistan was the only Muslim country in which hundreds of demonstrators gathered to show solidarity with the dead terrorist figurehead.

The cardiovascular benefits of rooibos tea

Due to their effects on vasodilation and vasoconstriction, angiotensin I-converting enzyme (ACE) inhibitors and nitric oxide (NO) are used to treat conditions such as high blood pressure and heart failure. In one study, the effect of green tea, black tea and rooibos tea on ACE and NO was compared in healthy human volunteers (link). None of the three had a marked effect on NO concentration, but both green tea and rooibos tea inhibited ACE activity, suggesting that they have cardiovascular benefits. This is in contrast to an earlier in vitro study which found that only green tea and black tea inhibited ACE (link).

Closely related to cardiovascular disease is diabetes. The good news is that that rooibos tea may help with this as well. In a mouse model of type 2 diabetes, aslapathin suppresses the increase in fasting blood glucose levels. It also improves glucose tolerance, apparently through stimulating glucose uptake in muscle tissues and insulin secretion from the pancreas (link). Drinking rooibos tea during a meal may not be a bad idea.

And you told me that you also stand more?

A.

I really do stand up at least every 20 minutes now, because I was spending five or six hours unmoving in my chair. The science is really clear that that is very unhealthy, and that it promotes all sorts of disease. All you have to do to ameliorate that is to stand up. You don’t even have to move. I’m standing up right now as I talk on the phone. I stand during most of my interviews now.
