Continuing on the topic of the best path to obtaining an education in nutrition.... Just like in most professions, the formal education mostly sets the stage and gives someone basic preparatory skills to go out and function in the profession. In addition, graduate work, and post graduate work, will give provide more education and preparation. The education needed to get an RD, or to get a BS or a MS or a PhD in nutrition, is valuable and helpful but can never cover everything. As someone continues on in the process of graduate work, they can pick a specific area to focus more on, and so their education in that specific area, would become greater. Also, once they get the basics, there is specialized education, training and continued education available, but again, one would have to really look for it, and it is usually broad scoped or a narrow perspective. I have taken some excellent continuing education classes in the traditional fields. |

Agave: Health Food, Health Fad or Health Fraud? Agave has become the sweetener of choice for many health enthusiasts. It is appearing on store shelves everywhere, in many new products and being promoted in magazines and cooking shows. One of the main benefits we hear is that it is lower in the gylcemic index. Is Agave really a health food and something you should be including in your diet? No, but to understand why, let us take a closer look at the issue. To begin with, we have to understand some points about fructose which is the main form of sugar in Agave. Fructose is metabolized differently than other sugars. Instead of going into the blood stream (where it could raise blood sugar), most of it goes directly to the liver. This is why Fructose has a lower Glycemic index as the GI is based on a foods influence on blood sugar. While many promote this as a positive, as the consumption of fructose tends not to raise blood sugar, fructose, or any concentrated caloric sweeteners high in fructose, can cause elevated levels of triglycerides and increase someones risk for heart disease. It may also somewhat increase the risk of metabolic syndrome/insulin resistance. And these effects are most likely in those who are insulin resistant, and/or overweight and/or obese. It also may not effect the satiety mechanism as well as pure sucrose. For the record, these are all the reasons we are being told to avoid High Fructose Corn Syrup (HFCS) as it has a higher level of fructose than regular table sugar or regular corn syrup. Here is the real irony in all of this. |
