Equine metabolic syndrome (EMS) is a collection of factors and events within the horse affected by food, stress, and sleep. This podcast summarizes information in general terms for most horse owners. While preparing it for broadcast, I realized that making a part two would help further understand the questions raised within this podcast. This podcast covers the ingested materials (air, water, minerals, fats, sugars, and proteins) and what they do within the body. It covers the role of insulin, insulin resistance, and its relationship to metabolic syndrome. Also discussed are the secondary diseases of EMS, including laminitis, muscle loss, and others. I make this all understandable for those without scientific minds. After all, if you can't understand how to feed them, how will you be able to Help Horses Thrive In A Human World? Unfortunately, we depend on misinformation from product marketing, causing most of the lameness and illnesses of horses today. We must get our horses' metabolism right to do "the best for our horses." Feeding them according to their evolution, adjusting to their current environment, reducing their stress, and improving their sleep are all necessary.
