I think potatoes are some of the healthiest foods you can eat. They’re full of potassium (40% more than bananas), vitamin C, and fiber. They’re low in calories and they’re fat-free. They provide resistant starch that feeds intestinal bacteria, supporting a healthy gut microflora, characteristics of which (e.g. production of short chain fatty acids) have been shown to lower blood glucose and body fat. And they taste great!
Here’s Dr. McDougall defending the potato:
And here’s Chris Voight, the man that Dr. McDougall mentioned who ate nothing but potatoes for 60 days, about 20 potatoes a day. He lost 21 pounds. His cholesterol dropped 67 points. He lost body fat. His blood sugar came down. His triglycerides came down. Every lab value measured “either stayed the same or got better.”
Voight says, and I agree, that against a backdrop of a high-fat diet, potatoes, actually most high-carb foods can be a problem. In a whole food, plant-based diet, where less than 15% of calories come from fat, potatoes stand out as an excellent food.
