Today, we cover three foods to avoid for better horse health. This topic ties into our last discussion, where we explored toxicity in horses and how accumulated toxins can build up over time and lead to serious health issues.

Sources of Toxicity in Horses

Horses get exposed to various sources of toxicity, mainly through chemicals and preservatives in their food and water, medications, vaccinations, and deworming agents. Over time, the toxins build up and can overwhelm the immune system, leading to chronic health issues like inflammation, allergies, and sensitivities. Addressing the diet and removing toxic elements is often the first step toward recovery when horses are unwell.

Corn

Corn has high-calorie content and energy density, making it a common ingredient in horse feed. However, corn lowers digestive pH, leading to leaky gut and immune issues. It is also high in starch, which can overwhelm the small intestine if fed in excess, as the undigested starch can reach the hindgut, where it ferments, potentially causing acidosis, colic, or laminitis. Its low fiber content and imbalance of protein and amino acids make it less suitable as a standalone feed. There is also a risk of mold contamination when corn is improperly stored. While corn can be an energy boost for horses with high caloric needs, it is best to use it sparingly.

Wheat Middlings

Wheat middlings, a byproduct of milling wheat for flour, are often used as a source of fiber and protein in horse feed. They can be high in phosphorus and low in calcium, creating an imbalance that can affect bone health in horses if consumed in excess. Wheat middlings can also ferment in the hindgut, leading to digestive upsets like colic or laminitis. High levels of non-structural carbohydrates in wheat middlings can also be problematic for horses prone to metabolic issues like insulin resistance or equine metabolic syndrome. While middlings can be part of a balanced diet, feed them in moderation and combine them with other sources of fiber and essential nutrients.

Processed Oils

Canola, soybean, corn, or hydrogenated oils are not ideal for horses as they undergo high-temperature processing that generates free radicals, harming the immune system and leading to various diseases. Soybean oil can also create hormonal imbalances due to its phytoestrogen content. It is essential to choose cold-pressed, high-quality oils and only add them to the diet when necessary.

High-Fat Diets

High-fat diets can provide energy for horses doing heavy work or needing to gain weight, as fats are calorie-dense and provide slow-burning energy without the risks associated with high-starch feeds. However, horses lack a gallbladder and are biologically unsuited to process large quantities of oils. So, high-fat diets can cause digestive issues, malnutrition, and liver strain, slowing gut motility and worsening conditions like colic or ulcers.

Balancing Nutrition

While some challenging cases, like underweight or elderly horses, may require short-term use of problematic foods or oils, the goal should always be to provide high-quality, minimally processed nutrition in the long term. Horses thrive on a natural diet that aligns with their biology. For optimum health and resilience in your horse, pay attention to sensitivities and make adjustments where necessary.

Final Thoughts

Avoid ingredients like corn, wheat middlings, and processed oils. Focus on natural, high-quality feeds, and tailor the feeding strategy to fit the specific dietary requirements of your horse and support its long-term health and vitality.
