Can potatoes be consumed safely?

Potatoes can generally be consumed safely, but there are some considerations concerning their glycoalkaloid content, specifically solanine, which can pose health risks if consumed in large amounts.

1. Green Potatoes:

   • Potatoes that have turned green or started sprouting contain higher levels of solanine, which can lead to digestive issues such as nausea and vomiting. It is advised to avoid consuming green potatoes or ones that are sprouting 1 2.

2. Cooking and Preparation:

   • Cooking and processing potatoes reduce solanine levels and make them safer to eat. Hence, eating raw potatoes is not recommended, but cooking them thoroughly is safe and recommended 3.

     Tomatoes have long been misunderstood due to their resemblance to other nightshades, leading to irrational fears. While they contain a compound called tamatine, humans are largely unaffected by it, and many myths surrounding tomato toxicity, such as lead poisoning from plates, are likely exaggerated. Historical tales of tomato-related fears, including those involving George Washington, are probably fabrications, highlighting how misconceptions can persist over time.

3. Inflammation and Sensitivity:

   • While some worry about nightshades (like potatoes) being inflammatory, the evidence suggests that unless you consume large quantities of green potatoes, they are unlikely to cause significant inflammation. Additionally, certain compounds in potatoes can have anti-inflammatory properties and help inhibit cancer cell growth 2 4.

4. Nutritional Benefits:

   • Potatoes are rich in resistant starch, particularly when cooked and then cooled, which can benefit the gut microbiome by promoting the production of short-chain fatty acids like butyrate, beneficial to overall health 5 6.

5. Food Safety:

   • In terms of food safety, it is better to avoid keeping cooked potatoes at room temperature for extended periods to prevent bacterial growth. They should be stored properly to avoid foodborne illnesses 7.

Overall, potatoes, when properly prepared and consumed in normal amounts, can be a safe and nutritious part of your diet.
