Grain-Fed vs Grass-Fed and Finished Beef — Why Does it Matter?

By the Dr. Perlmutter Team

Americans eat a lot of meat. In 2018, the United States Department of Agriculture projected that the average person would consume over two hundred pounds of chicken, pork, and beef by year’s end. That’s more than half a pound daily per capita, every day of the year! While it is possible to consume an omnivorous diet and maintain a healthy lifestyle, we recommend viewing meat as a garnish or side dish rather than the focus of your meal. The perfect plate is full of colorful, above-ground leafy vegetables and healthy fats, with a three-to-four ounce serving of meat. Furthermore, should you choose to consume meat, it’s very important to remember that not all meat is created equally.

One of the most important factors in determining the overall quality of meat—especially red meat—is the dietary patterns of the livestock that produced it. When you think about it, this makes perfect sense: the food an animal consumes is used by their body to grow and develop, and, ultimately, becomes the very food that we consume. Feeding cattle a nutrient-poor diet will, in turn, produce a nutrient-poor food source, compared to cattle fed a natural, nutritious diet.

As it turns out, the age-old adage “You are what you eat” applies to cattle, too! Continue reading

Thanks to hosting The Empowering Neurologist, I’m always receiving copies of some of the latest and greatest works of scientific study from colleagues across the globe. As I was doing a bit of spring cleaning recently, I came across countless titles that have inspired and shaped my perspective on health over the past several years. Before I put these away, and in honor of today, National Doctors Day, I wanted to share some of these titles with you. Continue reading

Benefits of Probiotics for your Mood, Gut, and Immune System

By: The Dr. Perlmutter Team

One of the most exciting developments in lifestyle science over the last decade has been the sharpening focus on the central role that our resident microbes (bacteria) play in regulating overall health. These microbes, together with their genetic material and metabolic byproducts make up what is collectively known as the microbiome. It is becoming readily apparent that the trillions of microbes living on and within us play a fundamental role in almost all of the systems of the body. Even as recently as 10-20 years ago, we did not understand the extent to which the gut microbiome can influence a person’s mood, regulate appetite, produce essential vitamins, regulate the immune system, and influence systemic inflammation.

There is even evidence to suggest that the microbiome affects us on such a fundamental level that it can regulate the expression of our DNA! Continue reading

Vitamin D and Alzheimer’s Disease: Could Deficiency Increase Your Risk?

Vitamin D and Alzheimer’s Disease: Could Deficiency Increase Your Risk?

You know, we’ve explored, several times now, the relationship between vitamin D levels and risks for severe health complications, including dementia. Notably, my colleague Dr. Dale Bredesen has written and researched much on this topic, particularly with regard to the relationship between vitamin D levels and Alzheimer’s risk. In fact, Dr. Bredesen even includes vitamin D supplementation in his protocol for treating Alzheimer’s and dementia. Continue reading

Today we are going to review a new book, The Longevity Solution, written by Dr. James DiNicolantonio and Dr. Jason Fung. Much about this book can be learned from its subtitle: “Rediscovering Centuries Old Secrets to a Healthy, Long Life.” The point being that much of what this book describes was known by our ancestors, and it’s our job to unlearn what we’ve come to know about aging, and relearn this crucial ancient wisdom.

This fascinating book does a deep dive into the mechanisms that are involved in aging and then takes up some very interesting topics that are currently a part of our day-to-day discussions relating to aging, including the notion of fasting, the importance of understanding health implications of foods like like tea, red wine, and coffee, the controversial ideas of consuming dietary salt, why magnesium matters, what makes for a healthy versus unhealthy fat, and even explores Blue Zones, areas in the world in which there is extended lifespan.

So let me invite you to move on to our interview and learn more.
