Some researchers believe that environmental pollutants and industrial chemicals are to blame for the obesity epidemic. This, of course, bucks the conventional wisdom that our increasing girth is simply the result of eating too much and exercising too little. What’s the evidence to support the idea that chemicals are the true cause of our ever-expanding waistlines? Find out in this week’s Nutrition Diva podcast.
Q. I have seen a lot of conflicting information about the safety of farmed-raised fish. I stopped buying farm-raised salmon years ago because of the concern. How does farm-raised trout stack up to other fish in terms of nutrition and safety? Where does most of the supply come from in USA?
A. Unfortunately, this issue is a moving target. Exponential growth in aquaculture and the pressure to control costs means that procedures are constantly evolving. If watchdog groups make enough noise about a safety or nutrition concern, the industry often changes practices in response. So, something that was a concern a few years ago may no longer be a problem. (See, for example: Farmed salmon gets an anti-inflammatory makeover.) However, newer concerns may have cropped up in the meantime.
The best resource I’ve found to keep up with these issues is Seafood Watch. These guys are working hard to stay on top of all of these issues and to provide up-to-date resources for consumers trying to make safe and responsible choices. They have a number of tools for consumers, including a mobile app for your smart phone or a low-tech wallet card, as well as in-depth reports on individual fish. According to the fact-sheet on farmed trout, most of the farm-raised trout in the U.S. is produced in Idaho, with a minimum of negative environmental impacts. They consider it an excellent choice.
You’ll usually only find carob at health food stores or in the “healthy food” aisle of the regular grocery store. So, what are the advantages of substituting carob for chocolate? How do the two compare nutritionally? Find out in this week’s show.
I’ve gotten half a dozen requests from readers to weigh in on krill oil, an omega-3 supplement that’s supposed to be even better for you than fish oil! Of course, it’s also more expensive. So let’s take a closer look at what advantages krill oil might (or might not) offer and whether it’s worth the premium price. Read or listen to it here.
We hear a lot about the importance of eating a varied diet, but is it truly essential? Why couldn’t you just eat the same healthy meal plan every day? I discuss the advantages (and potential disadvantages) of a varied diet in this week’s episode. Read or listen to it here.
