What is TasteOverTime?

TasteOverTime is a website focused on taste and aging! We aim to be a go-to for:

  • Advice on great tasting foods and beverages for health and well being
  • Know-how, tips and techniques about the sense of taste
  • Resources for eating and drinking while aging tastefully

TasteOverTime Mission

To be the go-to website for state-of-the-art information and services about taste and aging for:

  • Consumers and the public
  • Food, nutrition, health, medical and science professionals
  • Advertising and public relations agencies
  • Food and beverage manufacturers
  • Media and social media

Why TasteOverTime?

The global population is aging faster than any other demographic. Since taste diminishes with age, many people may not have information, tools and techniques to address changing tastes.

As a result, nutrition, health and well-being may suffer. The target audience of TasteOverTime is aged 50+ years; however, tasteful recipes, tools and techniques will have broader appeal to people of all ages and circumstances.

TasteOverTime is primarily designed for people who shop and cook. We also appeal to people who use pre-packed foods and beverages to “cook off” from food retailers, or “add on to” from restaurants.

TasteOverTime also aims to serve care providers responsible for food and nutrition decision-making, and healthcare professionals who provide food and beverage advice to their patients and clients.

My Story

I’ve always had discriminating taste. But not all good.

Growing up, I was expected to eat everything, so I manipulated my foods to make sure everything tasted “just right”.

This usually involved condiments, like BBQ sauce, ketchup, soy sauce, Worcestershire sauce—and all things pickled. Who knew these tasty pleasures deliver the fifth taste of umami?

Fish was on the weekly menu. The only way I could stomach it was with sour cream and lemon juice, while I held my nose! Strangely enough, I was an early adaptor of sardines—again with lemon. Who knew acid balances the sweetness of fish?

I loved long-cooked dishes, like stews and casseroles. And most foods overcooked, since my mother only knew one degree of doneness. This meant browned crusts on everything crustable—and yes, burnt toast. Who knew slow cooking and browning makes foods yummy?

Fast forward to my career in culinary nutrition, when I was approached by an ingredient company to teach everything about taste, with an emphasis on taste and aging. It’s been a 30-year adventure—the passion of my life’s work, and the inspiration for this website. Who knew taste matters?

My early taste preferences for umami-rich and acidic ingredients foretold my sense of taste today—like why I like chocolate after Mexican food, and aged Parmesan cheese as a taste uniter. I now love all the basic tastes (acidic, bitter, salty, sweet and umami or savory), and how they masterfully shape food desires, health and well-being. Who knew taste could be so vital?

Basic tastes tend to change over the years—often unknowingly. It’s my goal to be your go-to resource for tasteful ideas, recipes and meals to ensure great tasting, desirable foods and beverages as time marches on.
