The Genetics of Smoking

/in /by

The 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 /by

A 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 . . .

Curcumin: Question 3

/in /by

Most super herbs and juices come from other countries—açai from Brazil and noni from Southeast Asia to Australia. Curcumin seems to have been used in India for hundreds of years. As we finish this look on questions we should ask about the latest and greatest nutrient, juice, or herb, this is most likely the simplest question of all. Here’s the obvious question: do the people where the herb is traditionally used live longer than we do in the U.S.?

I’ll stick with curcumin and India. Although our official life expectancy just decreased a couple of . . .

Observations: Easy to Believe

/in /by

In the past few months, I’ve gotten many questions about my thoughts on a video series that claims to reveal the truth about cancer. I watched as much as I could. When some parts were absolute fabrications, I just fast forwarded. There was nothing really new; I’d seen everything before over the years.

One of the basic premises was that the pharmaceutical industry is suppressing cures for cancer so they can make money selling treatments that won’t work. That’s a degree of cynicism that I don’t understand, and yet it’s something many people believe . . .

Curcumin Research

/in /by

Curcumin is fast becoming one of the most researched phytonutrients in the world. As evidence, in 2000, there were about 100 papers published on curcumin; in 2015, there were 1,100 papers published. And in the first quarter of this year, there were over 400 papers published. Why all the attention on this yellow phytonutrient?

I mentioned the anti-inflammatory and antioxidant qualities on Tuesday. The focus of a lot of research is for curcumin’s use as a potential cancer treatment and preventive for Alzheimer’s disease. Most of these are test-tube studies. Researchers are trying to examine . . .

The Bottom Line on the Latest Sucralose Study

/in /by

“Sucralose causes cancer.”

“Sucralose prevents cancer.”

You’ve got to be confused when you read those recent headlines about the same research study! You read or listen to my messages because you want to know what I dig out of the original research to get past the confusion. Well, let’s get to it.

 

The Data

The data were messy (1). When you look at the numbers in the table that reported the incidences of cancers, the patterns were not clear. Using the data on the male mice, the incidence of cancers went . . .

Does Sucralose Prevent Cancer?

/in /by

After Tuesday’s message, I’m sure that you were reading labels and getting ready to throw out foods that contain sucralose based on that single study (1). I’d wait a while, at least until I get finished reviewing this study. Today let’s take a look at another headline that says sucralose prevents cancer in some mice (2). This was an article written by Emily Willingham, a regular contributor to Forbes. She did what I usually do: read the actual research paper and then check out the claims the authors made. I’ve read it, but . . .

Sucralose: A Tale of Two Headlines

/in /by

One of my biggest complaints about health news is science by headline. Over the weekend, the headlines exploded with the news that in a recently published study, sucralose caused cancer! You know that’s going to catch my attention. Artificial sweeteners are part of the third-rail of health topics that include GMOs, soy, and vaccinations. What made this so interesting was that there was another headline based on the same study that said sucralose reduced the rate of cancer. That’s what we’re going to talk about this week.

Let’s start with the “sucralose causes cancer” headlines . . .

Processed Meat and Cancer: The Science

/in /by

In response to the headlines about processed foods and colorectal cancer, I decided to look at some of the research on cancer and colorectal cancer. Rather then write a long drawn-out article, I’m going to give you the bottom line on what I found.

  • The risk of getting any type of cancer in a lifetime is one in two for men and one in three for women (1). The lifetime risk of getting colon cancer is 4.84% for men and 4.49% for women. If the risk is an average of 18% higher by eating . . .

Processed Meat and Cancer: The Headlines

/in /by

Processed Meat Causes Cancer! That was the type of headline that dominated the Internet news sites, newspapers, and local and network news. One very well known nutrition expert wrote this comment:

The just-released report from the International Agency for Research on Cancer judging processed meat as clearly carcinogenic and red meat as probably carcinogenic has caused consternation among meat producers and consumers.

Note the verbiage that says processed meat is clearly carcinogenic. More about that in a minute. California just announced it’s considering adding processed meat to the . . .
