The Bottom Line on Cats and Dogs and Supplements

/in /by

One of my all-time favorite movie lines is by Bill Murray’s character in the original Ghostbusters. He goes on a rant about the coming plague of ghosts and says “…dogs and cats living together…” It’s the delivery more than the words, but it still makes me laugh. I often blurt it out when people talk about all the things that could go wrong if X happens.

I decided to search the literature for specific supplements that can benefit cats and dogs, whether they live together or not. There’s no research on multivitamins-multiminerals per se, although there’s some info on the use of vitamins and minerals as additives to food.

Cats and Supplements

There are two primary areas of research on supplements in cats. The first is the amino acid taurine and the other is joint issues. The lack of taurine in a cat’s diet can result in compromised immune systems, eye problems including blindness, deafness, cardiomyopathy and heart failure, and reproductive issues. Researchers have found that taurine supplementation can increase the taurine level in a cat’s cardiac tissue. One more thing: soy interferes with taurine absorption or utilization, so make sure that the food you feed your cat is soy-free.

The other issue is joint problems such as arthritis. In research on cats, the same blends used in humans that consist of glucosamine, chondroitin, Boswellia, and fish oil help alleviate pain as assessed by owner and veterinarian pain evaluations.

Dogs and Supplements

The big issue with dogs is joint problems such as osteoarthritis. Research shows that the same nutrients recommended for cats and humans are appropriate for dogs: glucosamine, chondroitin, Boswellia, and fish oil. When it comes to amino acids, dogs require 10 essential amino acids to be healthy. While they can get that from vegetarian protein, research shows that dogs can smell it when meals don’t contain all the essential amino acids and will avoid them. That’s some sniffer dogs have!

In the category of interesting research, the amino acid l-arginine together with antioxidants has been shown to benefit dogs with memory issues. Also medium-chain triglycerides are being tested in epileptic dogs to see if the supplement can help reduce seizures. Maybe a teaspoon of coconut oil every day can benefit these dogs—there’s no harm in it while waiting for the research to be completed.

The Bottom Line

We love our cats and dogs and want them to being as healthy as they can be. Targeted supplementation for specific issues is certainly warranted, and it’s probably good to use the same recommendations for us humans and for our best friends: eat better, eat less, and move more. You’ll both be healthier for it!

Can Medium-Chain Triglycerides Help with Alzheimer’s Disease?

/in /by

Medium-chain triglycerides are hot today. Derived from coconut oil or palm oil, they have the advantage of being used for energy without much processing by the liver. People doing the ketogenic diet use them, as well as athletes looking for more energy. From a medical perspective, MCTs are used for people with fat-absorption problems and to treat epilepsy in some people. For today, I’ll focus on the use of MCTs for preventing and treating Alzheimer’s disease.

From an examination of the research on those two specific areas, the research is sparse. There’s little to no research that MCTs will prevent Alzheimer’s disease. There are a couple of small studies that have been done to treat Alzheimer’s patients with coconut oil or MCTs, but the results are equivocal.

The reason MCTs may benefit the brain is energy production via a non-sugar-based pathway. Whether additional energy for the brain helps learning and memory is unknown. What seems clear is that prediabetes and type 2 diabetes contributes to the development of Alzheimer’s, so it seems more important to lower refined carbohydrates and eat a more plant-based diet. I think including extra virgin coconut oil in a better diet could be helpful. At this point, specific MCT products seem unwarranted due to the lack of research. They may prove to be useful for some groups based on genetics, phenotype, and microbiome. Just not yet.

The Downsides of Going Keto

/in /by

News stories about the side-effects of the still-popular ketogenic diet are showing up more frequently, so let’s review those this week and look at what you can do to address the issues while still attempting to stay in ketosis.

The first side effect is generally diarrhea. With the newer version of the ketogenic diets, the emphasis is on fats and oils, which make up the majority of calories, with protein second, and carbs last. Two things seem to contribute to diarrhea. The first is the use of fats containing high amounts of medium-chain triglycerides (MCT) such as extra-virgin coconut oil and other oil products made with added MCT. The reasons are unknown; it’s most likely related to changes in the microbiome due to the radical change in diet, but it may be that it’s a question of volume of MCT. Oils such as olive oil don’t seem to cause the problem. The solution to this problem may be experimenting with different oils to find the ones that work better for each individual.

The other reason the keto diet can cause diarrhea is a lack of fiber. The keto eating plan has no significant source of fiber in a diet without grains, beans and legumes, and vegetables; a couple cups of lettuce aren’t going to help very much. Soluble dietary fiber supplements may help, whether psyllium, inulin, or other fiber sources. Begin slowly by adding 5 grams a day mixed with water and slowly increase it to 15 or 20 grams spread out over the day. It can add bulk to the stool and stop what has been described as explosive diarrhea.

More on Thursday. Tomorrow is the Insider Conference call. There’s time for you to join before tomorrow’s call at 9 p.m. Eastern Time. What are you prepared to do today?

Sports Nutrition Before Your Workout

/in /by

With the Olympics around the corner, sports nutrition’s a timely topic. Many sports nutrition products are available, but I’ve wondered whether you understood why you might use some of these products. This week, I’ll cover three areas of sports nutrition.

Let’s begin with pre-workout products—what purpose do they serve? The first purpose is to increase fuel availability. When you exercise, you need sugar released from glycogen and fatty acids released from fat stores; that allows your body to be ready to use calories from those fuels at a higher rate when you begin your . . .
