Olive oil is rich in antioxidants. Eating plenty of antioxidants has been shown to be effective in fighting free radical damage that can cause certain illnesses, including dementia.
The vitamin E found in olive oil plays a big part in brain health, as it protects cell membranes from free radical damage. Vitamin E may be the most important antioxidant for dogs.2
Several human studies have also determined such a link. One such study found that the consumption of extra-virgin olive oil, or olive oil, appeared to protect memory and learning ability, and reduce the formation of plaques involved in dementia.3
Given these results, it would appear that olive oil might help to protect your dog’s brain from mental decline. Adding a bit of olive oil to your pup’s daily diet could prove beneficial for brain health, especially if your dog is getting on in age.
