FAQs about Ground Beef, Seasonings, Olive Oil, Lemon Wedges, and Fish

ground beefJudging by the questions sent to health websites and publications, it seems that the more consumers learn about food safety, the more anxiety they have related to this ingrained habit we have of eating. Here are some foods consumers have worried about recently: rare ground beef, imported spices, olive oil for cooking, lemon wedges in water, and farmed salmon. These Q/As provide some understanding of the issues and some techniques for getting around the risks of contamination. Many of the answers quote scientists on the Shelf Life Advice Advisory Board.

Is Cheese Addictive? Only If You Eat It

CheeseThe definitive answer to the title question is an emphatic, "Maybe." Why?  It depends upon whom you ask.  It depends upon your definition of addicted.  It even depends on the type of cheese you're continuously munching on. 

 

This obscure question was brought to my attention by my daughter, who regularly sends me newsworthy links to topics she thinks I should cover on Shelf Life Advice. This time, she sent me a Discovery Channel online article by Alice Truong, who talks about casomorphins, which, as you might surmise from the last two syllables, are related to the addictive painkiller.  Here's what Truong says, "The primary protein in milk is casein. When the human body digests casein, it produces casomorphins, which have an opiate effect on humans.  Because cheese is denser than, for example, milk, the casein is more heavily concentrated, meaning that eating cheese produces a larger amount of casomorphins in the body compared to eating other dairy products."

How long can a pie be left unrefrigerated?

The answer is this: It depends upon what type of pie you're thinking of.  Because cherry pie is acidic and contains a lot of sugar (which is a preservative), it’s probably safe to leave it at room temperature, covered, for as long as a day or two if it doesn’t contain any eggs or dairy products. But keep in mind that refrigerating it sooner than that will extend its shelf life. Also, in a warm climate, refrigerate it sooner.

FAQs on Food Safety and Nutrition

berriesSince Shelf Life Advice emphasizes ways to prevent food contamination and postpone spoilage, it's not surprising that most questions the website or its editor receives are about proper food handling.  We're also asked about nutrition and shelf life.  Below, you'll find some recent questions that have come our way; they're answered by scientists who are members of the Shelf Life Advice Advisory Board.  

How To Wrap Foods For Refrigeration

Here are some tips for wrapping foods for refrigeration:
  • When refrigerating pre-packaged raw meat, poultry, or fish, don’t remove it from its original packing.  Food scientist Susan Brewer, Ph.D., explains why:  “In the U.S., most meat in the retail case is packaged in ‘modified atmosphere packaging,’ which is high in carbon dioxide.  The purpose of the CO2 is to suppress microbial growth.  If you unwrap the meat, you lose this protection.  In addition, every time you handle the meat, it becomes contaminated by the air, hand, and contact surfaces. Leave it in its original packaging (unless you are breaking it down to freeze it, in which case, microorganisms won’t grow).“

“Fresh,” “Natural,” “Processed”—What Do These Words Mean?

PoultryWords commonly used to praise or damn specific foods—words such as “fresh,” “natural,” and “processed”—mean different things to different people. They can be defined in two different ways by answering these two quite different questions: 

 

1) What do they mean to the U.S. governmental agencies that oversee our food supply?  

 

2) What does the average consumer think these words mean?

Proper Handling Of Produce In The Crisper(s)

  • Fruit should be ripe before being placed in the refrigerator because cooler temperatures slow down ripening.  Allow fruit to ripen at room temperature before refrigerating. 
  • Once it’s ripe, in general, fruit should be refrigerated to extend its shelf life.

Defining Some Current Language about Food

people eatingDo you understand everything the news media toss at you?  Keeping your vocabulary current is a challenge since new concepts continuously lead to the creation of new language.  Vocabulary related to food may involve words totally new to you. Often, they're from the language and cuisine of other countries.  But sometimes we hear familiar words used in new ways and common words combined into phrases that are confusing. Context may give us a vague idea of the meaning but not a precise one. Below is some clarification of the following: "health halo effect", "functional food," "food desert," "food insecurity," "traceability" and "sustainable/renewable resources."
