Digesting Animal Protein

Digesting Steak

“I’ve been treating eating disorders (ED’s) and obesity for nearly 25 years and have always had good outcomes.  My rate of success improved dramatically, however, when I discovered the critical role that processed food plays in causing as well as in preventing recovery from Anorexia, Bulimia, Bulimarexia, (a combination of the two) Binge Eating Disorder (BED,) Emotional Eating and Obesity. To this end, I find it of great importance to provide both my patients and readers with relevant nutrition information to aid in their recovery. You can view all my Nutrition, Fitness, and Health articles here.

Anytime we ingest food, our body releases digestive enzymes to break the food down or digest the food. Because animal protein (meat) is a more complex food, our body expends a much larger amount of digestive enzymes to digest it. The process of cooking meat destroys most of the naturally-occurring enzymes that are needed to break down meats complete proteins into amino acids that the body can utilize; the more the meat is cooked, the more naturally-occurring enzymes are destroyed. This is the main reason that a well-done steak is more difficult to digest than a rare steak. It’s also important to note that as we get older, our bodies naturally start to produce fewer digestive enzymes. Some meats take longer to digest than others; pork takes the longest to digest, followed by beef and lamb. The longer the meat takes to digest, the more digestive enzymes are exhausted.

Protein Digestion Times

There are several things we can do to make the digestion process of meat easier, especially when it comes to the harder-to-digest meats like pork, beef, and lamb. There are a few foods and supplements that naturally contain digestive enzymes including fresh, raw pineapple and fresh, raw papaya. By eating these fruits as accompaniment to meat, our bodies are less likely to be depleted of its own digestive enzymes. Fresh pineapple contains an enzyme called bromelain, while fresh papaya contains an enzyme called papain; both help the body to break down protein quickly. Sometimes, it may not be possible to eat fresh pineapple or papaya with your meal, especially if you are eating away from home.  In this case, there are combination bromelain and papain supplements available. Remember to always check the labels of your supplements for unwanted ingredients such as artificial sweeteners, MSG, and other neurotoxins.

Mercury in Seafood. Is it Really Unsafe?

“Making informed nutrition and fitness-related decisions can be somewhat overwhelming for those in therapy for eating disorders (anorexia, bulimia, bulimarexia, binge eating disorder) and obesity. To this end, I’ve compiled a set of handouts to provide handy reference guides to both my readers and clients. You can view all my Nutrition and Fitness Handouts here. Be sure to check back frequently, as I am always adding new handouts to my list!”

We’ve all seen headlines like this in the media, warning against the dangers of the mercury content of seafood. Are headlines like this completely true? Is eating a diet rich in fish truly going to lead to mercury toxicity?

Looking exclusively at the mercury content of fish is an inaccurate measure of “the dangers” of eating fish. In order to be accurate, it is essential to look at the big picture. Are there other components that play a role in the way our bodies process mercury? Let’s investigate.

Aside from mercury, what other important element does fish contain? Selenium! The USDA has released a report of the best food sources of selenium. Out of the top 25 food sources, 16 of these were fish.

Selenium is sort of a “magnet” to mercury. When we consume mercury with selenium, the mercury seeks out the selenium and binds to it. This binding makes it impossible for the mercury to bind to anything else in our body, such as brain tissue, organ tissue etc. Dr Nicholas Ralston, a top researcher in the “Selenium-Mercury” relationship in fish and seafood explains it like this:

“Think of dietary selenium as if it were your income and dietary mercury as if it were a bill that you need to pay. Just as we all need a certain amount of money to cover living expenses such as food and rent, we all need a certain amount of selenium … Only one major study has shown negative effects from exposure to mercury from seafood, and that seafood was pilot whale meat. Pilot whale meat is unusual in that it contains more mercury than selenium. When you eat pilot whale meat, it’s like getting a bill for $400 and a check for less than $100. If that happens too much, you go bankrupt. On the other hand, if you eat ocean fish, it’s like getting a check in the mail for $500 and getting a bill for $25. The more that happens, the happier you are.”

The Western Pacific Regional Fishery Management Council, released a really useful chart that shows the ratio of selenium:mercury content in the most commonly eaten types of fish. Print it out, put it on your fridge, refer to it often, eat fish!
