Let’s talk about laminitis and why diet absolutely does matter! 🍏🌱
Recently, I saw a post circulating that claimed laminitis isn’t caused by diet, and that it’s due to bad confirmation causing the P3 bone to rotate. Unfortunately, this is not factually correct, and it worries me to see misinformation like this continuing to be shared, especially when it could influence how horse owners feed and manage their horses.
Laminitis is a serious, painful, and potentially life-threatening condition. In severe cases, it can result in the need for euthanasia. Suggesting that diet has no role in laminitis isn’t just wrong, it is dangerous.
Here’s what the science actually tells us:
Laminitis is the inflammation and damage of the laminae - the tissues that connect the hoof wall to the pedal bone (P3). When these tissues weaken, P3 can rotate or sink. That rotation is a result, not a cause.
🥕 Diet-induced laminitis is well-documented in research. High intakes of non-structural carbohydrates (NSCs), e.g. sugars, starch, and fructans, can trigger laminitis in susceptible horses and ponies.
• Laat et al (2012) showed that excessive NSC intake (could be from bucket feeds or forage) leads to metabolic and inflammatory changes in the hoof’s laminae.
• Horses with equine metabolic syndrome (EMS) or PPID (Cushing’s) are at particularly high risk, as they can have an exaggerated insulin response to high-sugar feeds or rich grazing.
Management and diet go hand in hand. Controlling pasture intake, providing low-NSC forage, using balanced vitamin/mineral support, maintaining a healthy weight, and regular trimming of the hooves to keep them balanced are proven, evidence-based strategies for preventing laminitis.
So please be cautious with online advice. The wellbeing of horses depends on us basing decisions on science, not opinions.
If you ever feel unsure about your horse’s diet or laminitis risk, speak with an independent equine nutritionist or your vet. It’s always better to prevent than to treat ❤️🐴
