The Sugar Conundrum
/in Memos/by Chet ZelaskoDuring the holiday season, there are plenty of sugary snacks available. Candy, cookies, pies, all kinds of treats. But can something as simple as jam on toast, let alone the holiday treats, be an issue for someone with prediabetes or type 2 diabetes? With close to half of all adults afflicted with one condition or the other, any kind of sugar stops them in their tracks. I see people reading labels carefully in the grocery store and often hear the words “No good. It has sugar!” In the prediabetes and diabetes groups I . . .

Dreading Thanksgiving?
/in Memos/by Chet ZelaskoThursday is America's biggest eating holiday, and a lot of us who need to watch what we eat are dreading all the choices we'll have to make. How do you handle it?
Here's my suggestion: give yourself a moderate serving of everything that appeals to you and enjoy it thoroughly. If you absolutely must take a serving of Aunt Minnie's casserole, take a tablespoon or two; as long as you eat some, tradition is maintained and no feelings are hurt.
Then take a breather. Sit and talk with everyone for 10 or 20 minutes. If you . . .

Power Up with Vitamin B12
/in Memos/by Chet ZelaskoThe final supplement I’ll cover this week is vitamin B12, sometimes called the energy vitamin. Many vitamins are involved with energy production, but a lack of B12 can certainly cause problems with energy and other issues.
Vitamin B12 is also known as cobalamin and if you’re wondering, yes, this vitamin does include the mineral cobalt. There are two primary functions of B12 in the body. The first is to help reduce the chemical homocysteine to methionine while helping folate be converted into a usable form in the same reaction. Without enough B12, homocysteine increases inflammation in the body . . .

Do You Make Enough Coenzyme Q10?
/in Memos/by Chet ZelaskoThere’s one major difference between coQ10 and other vitamins, minerals, and nutrients such as omega-3s: we can produce coQ10 ourselves. The problem is that we may not produce all the coQ10 we need, especially as we get older.
CoQ10 is used in the production of energy from both carbohydrates and fat in the mitochondria of the cells. You remember mitochondria from science class; they’re often called the powerhouse of the cells. And coQ10 is the substance that’s used to produce that power. It’s critical in the steps where oxygen is used to produce ATP, the . . .

What You Need to Know About Omega-3s
/in Memos/by Chet ZelaskoThis week I’m covering basic information about three supplements. One of my favorites and one I don’t ever leave home without is omega-3 fatty acids.
There are three basic forms of omega-3 fatty acids: eicosapentanoic acid or EPA, docosahexaenoic acid or DHA, and alpha-linolenic acid or ALA. The body cannot make omega-3 fatty acids, so they have to come from food and supplements. ALA is an essential fatty acid—the body can make EPA and DHA from it but not very well—so getting EPA and DHA from diet and supplements is critical.

The Genetics of Smoking
/in Memos/by Chet ZelaskoThe study I’m examining this week is profound for a number of reasons. Identifying the genes that are affected by direct contact with the toxins in cigarette smoke provides one piece of a very complex puzzle. For example, they showed the difference in genetic mutations in the same type of tumors between smokers and non-smokers. The smokers had the genetic mutations while the non-smokers didn’t. So why did they get that type of cancer? That’s why I said it’s one piece of a puzzle. There are undoubtedly other factors involved.
With the information that . . .

Smoking and Cancer Update
/in Memos/by Chet ZelaskoA fascinating research paper was recently published in which researchers compared the genetic mutations found in 14 different types of tumors from chronic cigarette smokers and those who never smoked. They were attempting to see the differences in the genetic damage that occurred in tumors from the same organs between people who smoked and those who had never smoked. While they occur less frequently in non-smokers, some types of lung cancers still occur in those who never smoke.
This was complicated research to say the least. The research group had developed an algorithm that would look at over 90 . . .

The Bottom Line on a Low-Fat Diet
/in Memos/by Chet ZelaskoIn this final look at the opinion article in JAMA, I’m going to cover another statement the author made along with some thoughts on the article and why it matters.
In the article, he suggests that, based on the theory that carbohydrates do not cause weight gain, public health policy was changed to encourage the use of more starch and sugars (1). Specifically he cited Healthy People 2000 Nutrition Goal 2.15, which recommended that food manufacturers “increase to at least 5,000 brand items the availability of processed food products that are reduced in fat and saturated fat . . .

As Much Sugar As You Want!
/in Memos/by Chet ZelaskoContinuing the topic from Tuesday’s message, I’m going take a look at one specific statement that the author made in his article in JAMA (1). I chose it because he specifically stated it was used to justify the increase in carbohydrate recommendations in public health policy. I also had never heard of it before—and I’ve been around awhile. The inner quote was taken from an article written in 2001 (2) that was used as a reference in . . .

Low Fat: A Failed Public Policy?
/in Memos/by Chet ZelaskoThe recent series of messages on health hooligans was something I’ve wanted to write about for a long time. No sooner did I finish it than I got an email from JAMA announcing an opinion piece on the low-fat diet we’ve been told to follow for over 40 years (1). I spent some time over the past few weeks checking the piece and the research behind it.
The opinion was written by an expert in endocrinology, a physician and researcher. He has the credentials. But he is one of a number of scientists who’ve become critics . . .
