As previously discussed, there are significant nutritional differences between the meat produced by cows that eat grass and those that subsist on grain. Beef from cows that eat only grass contains higher concentrations of essential nutrients, omega-3 fatty acids, and conjugated linoleic acid. It also has lower levels of hormones, antibiotics and other toxic remnants from the industrial production process, which can have significant ramifications on our health, ranging from the microbiome to cellular health. Additionally, grass-fed cows live out their lives more closely aligned with how nature intended—freely roaming pasture land and consuming grasses available to them in their immediate environment—which makes the process more humane and environmentally-friendly.
However, like many of the buzzwords surrounding healthy living, there’s a lot of confusion and outright deception that surrounds the “grass-fed” descriptor. While certain trade organizations do their best to impose uniform standards, the use of the term “grass-fed” is, unfortunately, not regulated by the Food and Drug Administration or the United States Department of Agriculture. This sadly leaves the label open to abuse by unscrupulous producers looking to harvest the benefit of the term without putting in the effort to truly raise grass-fed cattle. The process of getting the “grass-fed” label approved on packaging for a given farm’s beef is incredibly lax, and actually doesn’t even include a farm inspection! Essentially, the government takes farms at their word when determining whether or not their product should be labeled grass-fed. Continue reading

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, and if you choose to eat meat, then a three-to-four ounce serving of meat. However, 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
As we all know, allergic diseases, particularly in childhood, are becoming more and more common. It’s not just that we are becoming more aware of allergic diseases, think of the frequent announcements on airplanes about peanut allergies, or food allergy questions by the waiter at dinner. No, the reality of the situation is that, by and large, allergies are simply far more common than they used to be.
So, why is this happening? Let’s take a step back and recognize that the intestines, oddly enough, actually play an important role in determining our immune responsiveness. Specifically, we now understand that the gut lining itself actually plays an important role in regulating immune function. Permeability, or leakiness, of the gut lining is associated with alteration in immune function as well as changes to the set point of inflammation. Continue reading
Antibiotics play an important role in medicine. Without a doubt, they can be absolutely life-saving. However, our own CDC tells us that about 30% of antibiotics used in America are used inappropriately or unnecessarily. That said, we are all generally familiar with the consequences of antibiotic abuse, including the creation of antibiotic-resistant organisms, as well as changes that can happen to the gut microbiota.
But there’s a new discovery with reference antibiotics that is turning out to be very important. We as physicians have always been trained to believe that antibiotics, while affecting bacteria, have no effect on the cells of the human body. We are now learning that this may not be the case. As you will see in the video, new research is demonstrating that antibiotics may have a dramatic effect in terms of damaging mitochondria, the energy-producing organelles that live within our cells. When we recognize that problems with mitochondrial function underlie many of our degenerative conditions, including Alzheimer’s disease and Parkinson’s disease, the idea that commonly-used antibiotics might threaten mitochondrial function becomes quite important.
