Olive oil and potatoes more filling

High-Monounsaturated fats such as olive oil and canola oil are more filling that high-polyunsaturated fats such as corn oil, and potatoes are more filling than rice according to a recent study from S. E. Specter at Pennsylvania State University and his French colleagues.
Once a week for four weeks, 12 young Parisian men were fed identical breakfasts followed several hours later by a lunch of chopped steak, bread, cheese, and apple and a starchy side dish of either rice or mashed potatoes, each served two of the four weeks.
To every 100 grams of rice and mashed potatoes the researchers added 48 grams of either a high-monounsaturated fat oil such as olive oil or a high-polyunsaturated fat oil such as corn oil.
The men then rated their desire to eat once an hour for the next four hours.
The men were less hungry after consuming the meal containing the high-monounsaturated fat than after the one containing the high-polyunsaturated fat.
The subjects also invariably felt less hungry after they had eaten the potatoes even though blood sugar levels were higher than after they had eaten the rice.
The researchers warned that the data was preliminary but wondered if monounsaturated fats such as found in olive oil might reduce the desire to snack.
Editor???s Note: Beware of potatoes. If I remember correctly ??? I cannot find it in their book right now ??? in the book “Protein Power”, Drs. Michael and Mary Dan Eades note that many years ago someone observed that people who ate certain foods were heavier than others, and people who talked about how they loved potatoes tended to be the heaviest of all.
