Reducing Calories Improves Immunity

The two-year results from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) clinical trial—the first controlled study of calorie restriction in healthy humans—were released last week. The purpose of the study was to determine the benefits and hazards of calorie restriction. Animal studies have demonstrated that reducing calories up to 40% […]

The Price You Pay

On Tuesday, I asked where you’re spending your time. There’s a price for everything that we do and what we don’t do, even if the outcome will ultimately be positive. Here’s a personal example. It’s no surprise to any reader that I had a knee replacement just before Christmas and have been spending time rehabbing […]

The Right Choices

What do you think is more important: the state of your garage or the state of your clothes closet? The state of your basement or the state of your car? The state of your desk or the state of your pantry? Do you want them neat and organized, or are you okay with going through […]

Update: E-Cigarette Safety

As the European Respiratory Society held their annual convention, several research studies made the health news, including e-cigarettes and vaping. The appeal of e-cigarettes is that they seem to be safe–you’re not actually burning tobacco with its associated chemicals and inhaling that into your lungs. E-cigarettes remove all that bad stuff and associated negative health […]

B6, B12, and Lung Cancer

The overwhelming message from the study I’ve been reviewing this week: don’t smoke cigarettes. Period. That’s the true cause of most cases of lung cancer. There was no increase in lung cancer in subjects taking high doses of B6 or B12 who never smoked or in those who quit more than 10 years before the […]

Behind the Misleading B Vitamin Headlines

Headlines are designed to be provocative. With so many sources of news to choose from, something must get you to click on that link. The problem is when the articles and posts are misleading and, in some cases, just wrong. There were primarily two things wrong about the two online articles I cited in Tuesday’s […]

Do Vitamins B6 and B12 Cause Cancer in Men?

The headline in The Atlantic said: “Vitamin B6 and B12 Supplements Appear to Cause Cancer in Men.” The Huffington Post said: “Men: Taking Vitamins B6 and B12 Could Increase Your Risk of Lung Cancer.” There were few news sources that didn’t pick up this provocative headline. As you might expect, I started to get questions […]

How Does Alternative Medicine Affect Cancer?

The final study this week is an analysis of survival data on people who selected only alternative medicine as treatment after being diagnosed with a non-metastatic cancer. The subjects declined any conventional cancer treatment defined as surgery, chemotherapy, radiation, and hormone therapy. Let’s take a look at this observational study. Researchers used the National Cancer […]

A Cancer Blood Test Gets Closer to Reality

Noninvasive detection of early stage cancers has long been a goal for researchers because earlier detection means earlier treatment. For some cancers such as ovarian and lung cancer, that can increase the five-year survival rate, the benchmark used to determine whether someone is cancer free. Here’s what researchers did: they developed a blood test that […]

How Vitamin C Can Stop Leukemia

Three recent studies related to cancer diagnosis and treatment, including alternative treatments, contain solid, meaningful research. That’s this week’s focus. The first study was published in the journal Cell. The title is the best way to describe the paper: “Vitamin C May Encourage Blood Cancer Stem Cells to Die.” The biochemistry in this paper is […]
