Why Dr. Wallach Advises Against Eating Baked Potato Skins

Dr. Joel Wallach, a pioneer in holistic health, has long advocated for dietary choices that support optimal well-being. One specific recommendation he makes is to avoid consuming the skins of baked potatoes. Let’s delve into the reasoning behind this advice and what it means for your health.


The Risk of Toxins


Dr. Wallach highlights that potato skins, particularly when baked, can accumulate high levels of toxins. Potatoes naturally produce glycoalkaloids, a type of toxin that serves as a defence mechanism against pests and diseases. These toxins are more concentrated in the skin, especially in potatoes that are not organically grown. When baked, these toxins can become more potent, posing potential health risks.


Nutrient Absorption


Another concern raised by Dr. Wallach involves the high fibre content in potato skins, which, while generally healthy, can interfere with the absorption of essential minerals. Potatoes are rich in iron and zinc, but the phytates found in potato skins can bind these minerals, making them less available to the body. This can particularly impact individuals with existing mineral deficiencies.


Pesticides and Contaminants


The skins of non-organically grown potatoes are often exposed to pesticides and other chemical treatments. These substances can linger on the skin, even after washing, making them a potential source of harmful chemicals. Dr. Wallach advises that if one chooses to eat potatoes, peeling them can reduce the intake of these unwanted contaminants.


How to Safely Enjoy Potatoes


Dr. Wallach doesn’t dismiss the nutritional benefits of potatoes altogether. They are a good source of vitamins C and B6, potassium, and energy-providing carbohydrates. However, he stresses the importance of how they are prepared. Here are a few tips:

  • Peel Potatoes: Removing the skin eliminates most of the glycoalkaloids and reduces exposure to pesticides.
  • Choose Organic: If you prefer to eat the skins, opt for organic potatoes, as they are less likely to be contaminated with harmful pesticides.
  • Cook Safely: Avoid overcooking potatoes to the point where the skins harden and char, as this can increase the concentration of harmful substances.




Dr. Wallach’s advice is grounded in his commitment to preventive health care. By understanding the potential risks associated with eating baked potato skins, you can make informed decisions that align with a healthful lifestyle. As always, balancing your diet with a variety of nutrients while considering food safety recommendations is key to maintaining good health
