The Inca Indians in Peru were the first to cultivate potatoes around 8,000 BC to 5,000 B.C. and they were only bought to Europe in the 1530’s by the Spanish. They are now the most important non-cereal crop globally.

Are potatoes healthy for dogs?

Potato protein is recognised as one of the most valuable non-animal proteins due to its high level of digestibility and high content of essential amino acids. It not only has a balanced Amino Acid profile but also a higher Essential Amino Acid score than egg and casein.

It is excellent source of many important vitamins and minerals including iron, a high vitamin C content that promotes iron absorption. Also, a good source of vitamins B1, B3 and B6 and minerals such as potassium, phosphorus and magnesium, and contains folate, pantothenic acid and riboflavin.

Potatoes are rich in antioxidant compounds like flavonoids, carotenoids and phenolic acids which neutralise potentially harmful molecules known as free radicals. When free radicals accumulate, they can increase the risk of chronic diseases like heart disease, diabetes and cancer.

10 Science Informed Reasons to Include Potato Protein in Your Dog’s Diet:

1. Excellent Nutritional Value – Potato protein is an excellent source of several nutrients, including vitamin C, which acts as powerful antioxidant and iron absorption enhancer, and beneficial plant compounds, including phenolic acids and flavonoids, that can help prevent chronic diseases. (4, 5, 6, 7)
2. Excellent Amino Acid Score and Balance – Potato protein has a balanced and excellent amino acid score. Higher than other plant proteins and egg and casein, the standard bearers for animal proteins, whilst closely resembling human skeletal muscle protein. (3)
3. Can Improve Blood Sugar Control – Potato protein has been shown to offer improved glycaemic and insulinemic responses than whey and rice protein, which is helpful in mitigating diabetes. (8)
4. Naturally Gluten-Free – This makes it ideal for those who suffer from gluten-allergy or are looking to eat a gluten-free diet for other reasons.
5. May Help Inhibit Cancer Cells – Potatoes antioxidant compounds, particularly chlorogenic acid, have been shown to inhibit cancer cell proliferation. (9, 10, 11, 14)
6. Supports a Reduction in Inflammation – studies have confirmed the systemic anti-inflammatory effect of potato which reduces the incidence of diabetes, heart disease, cancer and arthritis. (10)
7. Helps Repair Muscle Damage – Recent research showed that potato protein stimulated muscle protein synthesis both at rest and after exercise helping to retain or increase muscle mass. (12)
8. Supports Weight Management and Satiety – studies show that potato protein increases satiety and provides a better weight-reducing effect than other plant proteins. (13, 17)
9. Supports Healthy Eyesight – Phytonutrients lutein, zeaxanthin, and violaxanthin are known to be beneficial for eyes. (14, 15, 16)
10. Low Environmental Impact – as a waste product in the production of potato starch, potato protein has low global warming potential and is considered a ‘climate smart’ crop. (18, 19)
