"research" news and stories

Most of us will chow on anything without a hazard sign, but, for some, our abundant foodshed is a minefield. Even the most adventurous eaters have their Kryptonite -- Julia Child had a habit of tossing cilantro; Ruth Reichl refuses to eat honey.

Odd eating habits have plagued every walk of life, perfectly rational people, and confused scientists and indulgent omnivores for years. For some, it's sensitivity to texture that gets in the way of a good piece of fish. Perhaps it's something in our past (or another life) that makes us squirm at the mush of a banana or the tree-like tops of broccoli. The BBC recently interviewed a woman who can't eat pasta because it feels like tiny worms; a bite of tomato, like maggots. Some people's lists of don't eats are longer than their dos. So what causes this seemingly childish aversion to perfectly good food?

Thanks to the minds at Duke University, we may soon have our answer.

There's a new study out that has some bad news for Splenda users. According to the research, the sugar substitute may "suppress beneficial bacteria in the gut, and cause weight gain." It may also block absorbtion of nutrients.

The study was performed on rats and conducted at Duke University in North Carolina. However, it was co-sponsored by the Sugar Association, and the makers of Splenda were quick to respond. This could be a new, real health concern, or it could be a new battle in the sugar/Splenda war, or both.

While I'm not personally a fan of Splenda (just don't like artificial sweeteners), but I know that lots of people depend on it for sweets. I think this may be a wait and see situation, but may also be something to keep in mind next time you open a packet.

A recent study found that cherry tomatoes grown in salt water can turn out tastier and heartier than ones grown normally, partially because the plants have to fight harder to fight the environmental stress and produce more compounds to help them cope. These compounds contain antioxidants like Vitamins C and E, which have healthy effects on those who consume the fruit.

The solution only contains 20% seawater. Unfortunately, not all genotypes of tomatoes react in the same way to the salt water. Some die because they cannot counteract the free radicals from the solution, so don't try to do this with larger tomatoes; it probably won't work. In the study, the water was constantly circulated and the pH controlled by a computer, so the researchers promise that the tomatoes won't taste salty.

The researchers, based at the University of Pisaone in Italy, are encouraging the growth of tomatoes in brackish water, because it will not only lead to juicier, healthier tomatoes, but will help to preserve our freshwater supplies.

Researchers from Exeter and Oxford U asked 740 pregnant women (all first-time moms) to keep a food diary during their gestation periods.

Their findings? That women who ate more food and more nutrients were 24% more likely to give birth to a boy (specifically, 56% of the women in the group who ate the most gave birth to boys). The average woman who gave birth to a male consumed 2,413 calories a day and ate foods containing potassium, calcium and vitamins C, E and B12. The odds of having a boy were also higher among women who consumed one bowl of cereal every day (though the researchers didn't specify whether the bowl was eaten at breakfast or not).

But some people are wary of the stats, saying that a man's sperm ultimately decides whether a child will be male or female, and that diet has little or nothing to do with it.

If anything, hopefully the study will remind and encourage pregnant women to eat a healthy, well-balanced meal no matter what sex their baby turns out to be.

According to an article that appeared yesterday in British newspaper, The Guardian, the newest frontier in food is in the area of nanofood development. With nanotechnology, food could be manipulated to taste great, be low-fat and last forever, because it alters the food on an atomic level. For all the potential good this science could do, researchers are hesitant to move too far forward this work. Their reservations are due, in large part, to the backlash that genetically modified foods have received in recent years.

It's a lengthy article, with far more detail that I can neatly summarize here. It's eye-opening, in part because the possibilities are appealing and frightening. I personally believe that we should leave food alone, as it seems that every time we start messing with our food, we make the situation worse not better. However, with the food supply uncertainties we may in the years to come, it makes me wonder how science could help feed the world.
