Softer Care for Harder Cases, of Ebola and Everything Else

(5) Comments | Posted October 16, 2014 | 10:03 PM

The evolving Ebola outbreak is very disconcerting, to say the least. The situation in West Africa is, obviously, truly dire -- with projections of the toll escalating from terrible to calamitous day by day. A dreadful, transmissible disease in a part of the world where access to...

A Taste for Stealth

Stealth nutrition can work for you or against you. Unfortunately, it has been used against you by the food industry for years.

First, we need a definition. Stealth, of course, refers to actions that are secretive or concealed. The term has been applied to health -- by yours truly,...

Unscrambling Our Eggs

I recently saw a patient in my clinic who made me think about the many other patients like him I've treated over the years. He had a rather dramatic family history of heart disease, and had himself undergone coronary bypass surgery before his 40th birthday. He had, of course, seen...

The Nature of Medicine, and the Medicine of Nature

It is Naturopathic Medicine week. Who knew? As it happens, it is also Drive Safely Work Week. I guess we've planted so many flags of ownership into our annual cycle of weeks and days that we are now obligated to share real estate. I haven't heard the naturopaths complain...

Our Sodas, Stars and Selves: Where the Buck -- and Calories -- Stop

(0) Comments | Posted September 29, 2014 | 10:48 AM

To the inevitable backdrop of John Philip Souza marches and presidential photo-ops, Big Soda has announced that it will do some vague kind of something about the excesses they contribute to our intake of calories and sugars over something like ten years. (Unless, of course, they don't.) Cue the 21-gun...

Seeking the Sweet Spot, from Mouth to Microbiome

(1) Comments | Posted September 23, 2014 | 11:07 AM

A study out last week in the top-tier journal Nature told us that non-caloric artificial sweeteners (NAS) may contribute to glucose intolerance by mucking up our microbiomes. That's a serious indictment, since these products are intended to help defend against glucose intolerance, and other ills related...

A Cacophony of Culinary Lunatics

Let's face it, ISIS is pretty scary. But it isn't especially scary because it represents something like 30,000 men under arms. The U.S. alone could field a force of a million if need be, and our arms are much better, too. What makes it scary is the...

Salt in the Wound

(2) Comments | Posted September 12, 2014 | 3:09 PM

We eat too much salt, and so do our children. We can reduce our intake by eating less highly processed food, which is the source of nearly 80 percent of the sodium in our diets. Doing that, and eating more foods direct from nature would be good for...

Lifestyle Medicine: Have Hammer, See Nails, Seeking Spoon

Lifestyle is the best medicine. The perennial challenge is figuring out what makes the best spoon.
