After successfully forcing NYC restaurants to post calorie counts on menus and to stop cooking with trans fat, Dr. Thomas R. Frieden, the commissioner of New York City's Department of Health and Mental Hygiene, is waging a war on salt. A recent New York Times article explains that he's going after packaged food companies and mass-produced restaurant meals. Apparently, they contribute 80 percent of the sodium in the average American diet. Over the next five years, Dr. Frieden aims to cut the level of salt intake by 25 percent.

Is salt so bad for us? Salt, in some people (not everyone) can lead to high blood pressure which is a leading factor in the incidence of heart attack and stroke. At the same time, many scientists do not believe sodium intake is directly related to high blood pressure. In the past, studies comparing hypertensive populations found that those on low-salt diets had more than four times as many heart attacks as those on normal-sodium diets.

Although the health link may not be clear, what's obvious is that excess of most ingredients cannot be healthy. And, foods at fast-food chains, like McDonald's, are outrageously high in sodium. It seems that if dealt with in a reasonable way, Dr. Frieden's goal can be quite progressive. What do you think?

According to Best Syndication News, dog owners are becoming increasingly health conscious when it comes to the diet of their pets. Not only are people shopping at high-end dog shops, be they're even using natural healthy ingredients to bake fresh homemade dog biscuits and cookies for their dogs. Many dog owners are concerned about preservatives and additives that are found in commercial dog treats at the supermarket.

The good news is that there appears to be a growing number of alternatives when it comes to purchasing dog food. You can head to a natural pet health food store or a locally owned pet supply store. Dogs can be allergic to grains too. Purchase gourmet grain free doggie treats that are high in protein and low in carbohydrates. You can even find vegetarian dog snacks that are made with whole fruits and vegetables.

Online, you can purchase all natural pet foods from Only Natural Pet Store or Thrive Foods. Why shouldn't pet owners be concerned with their pets' diet? To me, the trend towards natural pet food makes sense. What do you think?

Are you feeling opinionated on a range of food topics, notably diets? On the website Opposing Views, you have the opportunity to view experts' arguments for and against low-carb diets, caffeine use, biotech foods, and on becoming a vegetarian. Afterwards, you can post your own comments.

There are so many overbearingly opinionated blogs. What a relief to finally find a site where doctors and scientists debate over hot topics. And, rather than totally ignoring what everyone else has to say, it fosters continued discussion with comments. Also, the site provides news headlines dealing with the various questions.

From all the food-related issues that Opposing Views thoroughly covers, I found the topic on caffeine the most interesting. This is no doubt due to my over sensitivity to caffeinated products. Also, increasingly we hear stories in the news stating that coffee can reduce our risks of diabetes, Parkinson's disease, and colon cancer. Just this past January, the media stated that doctors confirmed that while coffee helps fight type two diabetes, caffeine makes it worse. Such a contradictory study gives one an even stronger reason to check out this debate on Opposing Views.

When we learn about nutrition, we tend to focus on calories and vitamins. We're taught about which foods may prevent cancer and help our immune system. We normally concentrate on the physical effects of food on our body. It turns out however that foods have many more properties. According to a recent article from The Economist, foods also affect our cognition. They can enhance our mental health. Not only can certain foods improve our memory, but they can also prevent many of the negative effects of aging and even increase our lifespan.

Dr Fernando Gómez-Pinilla, a professor of neurosurgery and physiological science at the University of California, Los Angeles, conducted research on the way antioxidants and vitamins work with synapses in the brain. Based on his study, below are certain foods that can lead to a healthy brain:

As someone with an insatiable sweet tooth, I was fascinated when I found out that hormones in our body affect how we perceive and crave sweetness. They do this according to our body's nutritional needs. Since I have a pretty bad sweet tooth, does this mean my body needs more of it? Not exactly. A recent article in The Economist explains that scientists have done the first step; they've isolated hormones that affect our palate's sensitivity to sugar.

The reason why this study is so important is because it may lead doctors and nutritionists to find a solution for ways of reducing the desire for sugar-heavy foods, and thus reduce calorie-intake. Yuzo Ninomiya, a neuroscientist at Kyushu University in Japan, researched the effects of leptin, a hormone that regulates appetite and metabolism. His results show that when leptin levels are low, we are more sensitive to sugar, which means something tastes sweeter than when our leptin levels are low. The level of the hormone increases over the day. This might explain why we tend to eat lots of sugar in the morning ('cause it tastes so good!).

So, it seems, if scientists can figure out how to raise leptin levels (or at least keep them steady) throughout the day, then all of us sweet-tooth types might have a chance at eating less cake!

In a world full of sweets, it's not easy to avoid them. What are some ways you control your sugar intake?

Let's face it, all you food-loving, regular meal-eating types reading this site, you are the lucky ones. Most of you are blessed with a stove, maybe some ingredients in your cabinet, a bottle of wine half drunk atop your fridge. But if you're a city guy like me, always on the hustle for a dollar, always one dime short of a cup of coffee, always standing out in the rain in front of a hot food story, watching through rainy windows, then it's all about how to stay full and focused on the street, to not pass out while racing from one job interview to another, how to keep your nutrition at a full gallop while never actually sitting down. 

So God created the food bar! 

I'm sure to the average foodie these things are pox, a blight on nutrition and the gourmand's worst nightmare, but to us who dreamt as children of a future where we could eat candy bars for dinner, the nutrients in chocolate-flavored soy logs, are our life's blood; they keep our blood full of something other than caffeine and nicotine and urban despair. Trapped like jungle rats in a maze of dead-eyed salesman and bloodthirsty wall-streeters on their way to steakhouses and unemployment lines, we duck into the 42nd street bodega and grab our fix to go.

Here are some of the personal favorites:

Other than the cereal box treat, I've always been curious about the "recipes" that appear on boxes of cereal. Sure, I've seen people make fried chicken with corn flakes, but what about the other stuff?

My box of multi-grain flakes and nuts and fruits has a recipe for muffins. I tried it, but made several adjustments for taste and texture. I had to add more chopped nuts and raisins because let's face it, there aren't that many to begin with in a box of cereal, but other than that, the muffins weren't too bad. You just have to make sure that you crush up the flakes and let them soften before mixing into the batter, for who wants a flaky muffin?!

In the end, they taste okay, and work well if you're on the go, but I think eating cereal in a bowl with milk tastes better to me.

Now, if you'll just have this healthy beer for breakfast and for lunch, and a sensible dinner...

Beer. It could be the next product to use heart health benefits as one of its key marketing attributes, if the diet-blog's interpretation of new FDA rules catches on. According to a recent FDA announcement, "whole grain barley and barley-containing products are allowed to claim that they reduce the risk of coronary heart disease (CHD)." As we all know, beer contains barley! Next thing you know, your favorite brew will contain a label that says, "drinking this beer contributes to a healthy heart and may attract bikini-clad women!*"

Naturally, there's a catch. Evidently the beer is a bit too low on fiber to qualify. Oh well, maybe 2006 will bring more and looser FDA rules. We can but hope.

*That last part hasn't been vetted by the FDA. Yet.
