Despite all the hype about “low-carb” diets, many people have an incomplete understanding of carbohydrates. It helps to look at a Nutrition Facts label, which lists quantities per serving of total carbohydrates, dietary fiber, and sugars.

“Why am I always hungry?” Is that a question you often ask yourself, even after meals? Feeling hungry after eating could be due to leptin resistance. Leptin, a hormone produced by body fat, controls whether or not you feel full after eating.

When we think about depression, lack of motivation, or difficulty focusing and concentrating, the well-known brain chemical serotonin often comes to mind. While it’s true that serotonin deficiency is a problem for many people with depression and other mental health issues, researchers have known for years that other neurotransmitters such
Moderate drinking (one or two glasses a day) shouldn’t affect your cognitive function and may even provide some mild benefits. But chronic alcohol abuse can lead to alcohol-induced dementia due to the combined toxic effects of alcohol and the nutritional deficiencies often associated with alcoholism. In fact, heavy drinking (more
Although our conscious mind is closed to the outside world when we sleep, the rest of our body is not at rest. If you think of the body as a machine, sleep puts it in “idle” mode so that repairs can be made. Hundreds of biological processes continue: The heart
The science of whether some dietary choices are really “brain food” continues to unfold. Given the long time frames of conditions such as Alzheimer’s disease and other dementias, it’s challenging to prove any cause-and-effect relationship between specific foods and brain health. Most such associations are drawn from observational studies, in
With 16 million people expected to have Alzheimer’s disease (AD) by the year 2050, researchers are in a race against time to find an effective treatment, or better yet, a cure. However, progress on a drug that might halt or reverse dementia has been slow, and largely disappointing. Over the
Despite the tremendous amount of research that has been done and is ongoing, there is still no single definitive test for diagnosing Alzheimer’s disease (AD). In fact, the official diagnostic criteria most recently updated in 2011 by the National Institutes of Health and the Alzheimer’s Association rely primarily on clinical
Although it has likely been around since the start of humanity, it has only been in the past century that we’ve known about Alzheimer’s disease (AD). The growth in our knowledge and understanding of the disease combined with our increasing lifespan and the aging of the baby-boomer generation has led
Q: I recently started taking a proton pump inhibitor (PPI) for heartburn, but I have heard conflicting news about the safety of these medications. Are there risks of cognition problems and depression associated with PPIs?
A: PPIs work by reducing the amount of acid produced by glands in the stomach lining.
