When your horse has laminitis, every bite matters. You already know to skip the lush grass and sugary treats, but what about vegetables? Many owners want to offer a crunchy reward or a little variety in the bucket, but fear accidentally triggering a painful episode. The good news: there are several safe, low-sugar vegetables that can be a welcome addition to a laminitic horse’s diet. Here is a practical, owner-to-owner guide to the best choices, what to avoid, and how to feed them safely.

Why Sugar and Starch Matter in Laminitis

Laminitis is often tied to an overload of non-structural carbohydrates (NSC) , sugars and starches , that disrupt the gut and trigger inflammation in the hoof laminae. For a horse prone to laminitis, keeping the diet low in NSC is the cornerstone of management. Vegetables vary widely in their sugar and starch content. Some, like carrots and beets, are surprisingly high in sugar and should be limited. Others, like leafy greens and watery stems, are very low in NSC and can be fed more freely. Always introduce any new food slowly and in small amounts, and check with your veterinarian or equine nutritionist before making changes.

Top Safe Vegetables for Laminitic Horses

Celery

Celery is a fantastic choice. It is mostly water and fiber, with very low sugar content. The crunchy texture makes it a satisfying chew, and you can feed the whole stalk, including the leaves. Just wash it well and cut it into manageable pieces to prevent choking. Many horses love the crispness, and it is a great way to add moisture to the diet during hot weather.

Cucumber

Cucumbers are another excellent, hydrating option. They are virtually sugar-free and have a mild flavor that most horses accept readily. Slice them into rounds or long strips. Because they are so low in calories and sugar, you can use them as a frequent training reward or a boredom buster while your horse is on stall rest. You can even freeze cucumber slices for a cool, refreshing treat on a hot day.

Zucchini and Summer Squash

Zucchini and yellow summer squash are very low in sugar and starch. They have a soft texture that is easy to chew, making them suitable for older horses or those with dental issues. Grate a little over their regular feed or chop into cubes. These vegetables are also a good source of potassium and vitamin C, which support overall health without spiking insulin.

Lettuce (Romaine, Butter, or Red Leaf)

Dark, leafy lettuce like romaine is a safe, low-sugar green. Avoid iceberg lettuce, which has very little nutritional value. Romaine offers some vitamin A and K. Rinse the leaves, tear them into pieces, and mix them into your horse’s hay or feed. It adds bulk and moisture, which can help with digestion, especially if your horse is on a restricted hay ration.

Bell Peppers (Any Color)

Bell peppers are surprisingly low in sugar compared to many fruits and root vegetables. Red, yellow, and green peppers are all safe, though red peppers are slightly sweeter. Remove the stem and seeds, then slice into strips. Peppers are rich in vitamin C and antioxidants, which can support hoof health. Many horses enjoy the bright color and crunchy texture.

Pumpkin (Plain, Cooked)

Plain, cooked pumpkin (not the sugary pie filling) is a low-starch, high-fiber treat. Canned pure pumpkin (with no added sugar or spices) is convenient. Pumpkin is gentle on the digestive system and can help maintain a healthy gut. Feed only a few tablespoons per day as part of a balanced diet. The fiber content is beneficial for horses prone to hindgut issues.

Fun Fact

Celery and cucumber are so low in sugar that many equine nutritionists consider them “free feed” vegetables for laminitic horses. You can offer a whole cucumber or several celery stalks daily without worrying about NSC overload. Just remember to wash them thoroughly to remove any pesticide residue.

Vegetables to Avoid or Limit

Carrots

Carrots are a classic horse treat, but they are relatively high in sugar (about 5-6 grams per medium carrot). For a laminitic horse, this can be problematic. If you want to give a carrot, limit it to one small carrot per day, preferably cut into thin strips. Better yet, swap it for celery or cucumber as your go-to reward.

Beets (Root)

Beetroot is high in sugar and should be avoided. However, plain, unflavored beet pulp (the shredded byproduct) is actually low in sugar if it has been thoroughly rinsed and soaked. Many laminitic horses eat soaked beet pulp as a fiber source, but never feed the whole root vegetable.

Potatoes and Sweet Potatoes

White potatoes contain solanine, which is toxic to horses in large amounts, and they are also high in starch. Sweet potatoes are slightly lower in starch but still too sugary for a laminitic diet. Skip both entirely.

Corn

Corn is very high in starch and sugar, even when cooked. It is a common ingredient in many horse feeds, but for a laminitic horse, even a few kernels can upset the balance. Avoid feeding corn on the cob or loose kernels.

“The safest treat for a laminitic horse is one that looks more like a salad than a dessert. Stick with greens and watery stems, and your horse will thank you with sounder feet.”

How to Safely Introduce Vegetables

Start with a single vegetable type, offering just a small piece (about the size of your thumb) once a day. Watch for any changes in manure, appetite, or hoof sensitivity over the next 48 hours. If all is well, you can gradually increase the amount. Rotate between safe options to provide variety. Always wash vegetables to remove dirt and potential pesticides. Chopping into small, manageable pieces reduces the risk of choking, especially for horses that gulp their food.

If your horse is on strict stall rest, you can use safe vegetables as part of their enrichment. For example, place a few cucumber slices in a horse treat dispenser to encourage slow feeding and mental stimulation. This can help alleviate boredom without adding sugar to their diet.

Vegetables and Overall Hoof Care

While diet is critical, managing laminitis also involves consistent hoof care. Regular trimming by a skilled farrier is essential to maintain proper hoof angle and support. You can also support hoof health with topical products. A good horse hoof conditioner can help keep the hoof wall flexible and hydrated, which is especially important when your horse is on restricted turnout. Additionally, having the right tools for daily hoof cleaning makes a difference. A quality horse hoof pick allows you to clean the hooves thoroughly after any turnout or exercise, removing debris that could cause pressure or infection.

Always remember that every horse is an individual. What works for one laminitic horse may not work for another. Work closely with your veterinarian and farrier to create a comprehensive plan that includes diet, exercise (when safe), and proper hoof maintenance. Offering safe vegetables is just one piece of the puzzle, but it is a piece that can bring a little joy to your horse’s day without compromising their health.
