While potato allergies are considerably rarer than other common food allergies, they can trigger a range of serious symptoms in susceptible individuals. This guide explains what are the allergens in Simply Potatoes by examining their core ingredients and the potential risks beyond the potato itself.

Approximately 40% of the soluble protein found in a mature potato tuber is patatin. Patatin is the main storage protein in potatoes, meaning that its primary food source is potatoes and potato-derived products. For most people, patatin is a harmless nutrient, but it can trigger allergic reactions in sensitive individuals.

While potatoes are a global dietary staple, containing moderate amounts of protein and fiber, they also contain a family of small proteins known as LTPs. A study published in March 2023 identified 39 members of the lipid transfer protein (LTP) family in the potato plant, revealing their role in plant stress responses, but the risk for human allergy depends on individual sensitization and which specific LTPs are consumed.

Raw potatoes contain natural compounds called antinutrients, such as protease inhibitors and lectins, which can interfere with the body's digestion and absorption of nutrients. However, this leads many to question: **do potatoes inhibit protein absorption?** The answer is more nuanced than a simple 'yes' or 'no' and is largely dependent on how you prepare them.

According to scientific research, patatin constitutes up to 40% of the total soluble protein found in potato tubers. This versatile protein, also known as tuberin, is most famously found in potatoes, but its presence extends beyond the root vegetable to other parts of the plant and even to other plant species and organisms. Its unique enzymatic and storage properties make it a subject of extensive biological and nutritional study.

According to the YorkTest, sweet potatoes belong to a different botanical family than regular potatoes and do not contain the protein patatin, which is a major allergen in common potatoes. This critical distinction is vital for anyone managing a potato allergy, as it affects whether they can safely include sweet potatoes in their diet.

Did you know that patatin is the most abundant storage protein in potatoes, making up as much as 40% of the tuber's total soluble protein? For those wondering what foods have patatin, the answer is simple: primarily potatoes. This unique glycoprotein holds more than just nutritional value; it also has enzymatic activity and can act as an allergen.

While potatoes are often considered primarily a source of carbohydrates, their protein component offers a surprising array of nutritional benefits, including all nine essential amino acids. This makes potato protein a high-quality, complete protein, rivaling some animal-based options. Derived as a byproduct of the potato starch industry, this plant-based protein is gaining attention for its potential in food products and supplements.
