Determining the nutritional value of a specific vitamin in a specific food

My quest to understand vitamins concludes with this post. In reading The Vitamins by Combs and McClung, I sought answers to popular questions on the topic. What I found was that we are asking the wrong questions. It’s not about natural or synthetic. It’s about bioavailability and biopotency. It’s not about deficiency diseases. It’s about maintaining vitamin stores. It’s not about curing or preventing chronic … Continue reading Determining the nutritional value of a specific vitamin in a specific food

Vitamins: finding a spot between not enough and too much

My quest to understand vitamins has taken some interesting turns. Two weeks ago, I learned that whether a vitamin is natural or synthetic is not important.

This week, the third in a series of four, I turn my attention to vitamin bioavailability and … Continue reading Vitamins: finding a spot between not enough and too much

How much of a vitamin do we really need?

When I was growing up in the 50s and 60s, healthy eating was about a balanced diet. We got our nutrients from foods not from vitamin tablets. My dietary pattern included whole and processed foods.

Animal-based protein without the animal

The problem with meat is that it comes from an animal slaughtered and cut up to pieces for cooking and eating. Some animals have limited freedom before killing. Others don’t. Would it make a difference if meat was not associated with lives on a factory farm or in the slaughterhouse? There may be a solution on the horizon. It involves only choice cuts, less food … Continue reading Animal-based protein without the animal

Growing insects for food. Another alternative protein?  

My father used to talk about things coming in two sizes—too big and too small. When it comes to protein much of the world’s population fits into two categories—too much or too little. The Western Diet emphasizes meat at the center of the plate. That concept leads to overconsumption of protein. As incomes around the world have increased, more people have gained access to meat. … Continue reading Growing insects for food. Another alternative protein?
