The Portsmouth Historical Society presents Michelle Moon in her original program, Food For Thought, at the Discover Portsmouth Center on Sunday, Oct. 25, at 2 p.m.

Organic. Conventional. Eat Local. Free-range. Food Miles. Grass-fed. Slow Food. These and other buzzwords are popping up more and more recently, as Americans begin to reflect upon the sources of food and its journey to our plates.

It’s a current topic — but it has roots in our past.

Join Moon to discover how and why our food system has developed as it has, and how new partnerships among local museums, historic sites, and food organizations are helping people learn from the past to build a healthier food future.

Moon has been interested in food history and folklife since she learned to cook in the kitchens of her two grandmothers, one Yankee and one Texan. As director of education at Strawbery Banke, she oversaw the development of the Foodways Program, in which a team of skilled interpreteres researches and prepares dishes dating from the 1790s to the 1950s.

She is co-leader of Slow Food Seacoast, an active community group seeking to promote good, clean, and fair food on the Seacoast and worldwide. A graduate of Connecticut College, she has worked in museums and educational settings for more than 15 years.

Tickets are $10 ($7 for PHS members) and may be purchased at the door. The Discover Portsmouth Center is located at the corner of Middle and Islington streets in downtown Portsmouth.
