…at least according to researchers in Denmark who did a review of the scientific literature.
“The identified studies do not provide convincing evidence to suggest an association between intake of potatoes and risks of obesity, type 2 diabetes, or cardiovascular disease. French fries may be associated with increased risks of obesity and type 2 diabetes although confounding may be present. In this systematic review, only observational studies were identified. These findings underline the need for long-term randomized controlled trials.”

The nightshade family includes potatoes (not sweet potatoes or yams), tomatoes, peppers, eggplant, goji berries, and even tobacco. Anecdotal reports indicate that consumption of these either cause or aggravate specific chronic medical conditions, such as arthritis, chronic fatigue, or irritable bowel syndrome.
Georgia Ede, M.D., has an article on medical effects of nightshades at her website. The potentially offensive chemicals in nightshades are called glycoalkaloids. I looked into this issue when deciding whether to include potatoes in my version of the paleo diet. (They’re included).
Dr. Ede’s writes:
As with any food sensitivity, the only way to find out is to remove nightshades from your diet for a couple of weeks or so to see if you feel better. There are ZERO scientific articles about nightshade sensitivity, chronic pain, or arthritis in the literature, however, the internet is full of anecdotal reports of people who have found that nightshades aggravate arthritis, fibromyalgia, or other chronic pain syndromes.
I bet I could eat a couple potatoes and tomatoes every day without ill effect. And there’s Chris Voigt, head of the Washington State Potato Commission, famous for his 60-day potato diet. As they say, your mileage may vary.
