Complementary combinations create complete protein

The combination of wheat or rice with beans or lentils is referred to as complementary because they create a nutritionally complete protein.

To explain this, consider that proteins are an essential part of every cell, tissue and fluid in our bodies. Proteins are made from amino acids, which can be thought of as building blocks. The body uses 20 different amino acids to make its proteins. There are some amino acids that the body cannot make in required amounts and these are called essential, and they must come from the diet.

Complete protein foods have all the essential amino acids. In general, animal foods such as meat, poultry, eggs, dairy and fish are complete protein sources. Incomplete protein sources have low amounts of some of the essential amino acids. Combining two or more foods with incomplete proteins to provide adequate amounts of all the essential amino acids are referred to as complementary proteins. They do not need to be eaten together, so long as the day’s meals supply them all.

Some common food pairings that make a complete protein are:

  • pulses with grains, nuts, seeds or dairy
  • grains with dairy
  • dairy with nuts
  • dairy with nuts/seeds and pulses

In some information, the term legume is used rather than pulses. Pulses are part of the legume family (any plants that grow in pods), but the term “pulse” refers only to the dry edible seed within the pod. Beans, lentils, chickpeas and split peas are the most common types of pulses.

Punch down and form into loaves, place in well-oiled or buttered loaf pans. Oil or butter top of loaves, cover and allow to rise until double in size.

Bake in preheated 350F (180C) 30 to 40 minutes.

Cool on rack, remove from pans after 30 minutes, cool completely.

HomeFamily.net website updated

Arabic, French and Somali translations of some basic home economics videos will soon be available on the www.HomeFamily.net website.

The Manitoba Association of Home Economists has updated the website with new home economics resources for families, newcomers, Indigenous peoples and Manitobans living in northern communities.

Written and reviewed by home economists in Manitoba, HomeFamily.net provides consumers with relevant information and tools that can support them in preparing healthy, low-cost meals using locally sourced ingredients, and building confidence in making everyday decisions.

As an extension of the HomeFamily.net website, a printed booklet, Helping Families Live Well in Manitoba, will be distributed to Manitoba households in Harvest Manitoba food hampers throughout April.

The booklet contains affordable healthy eating tips, food shopping advice, food preservation information, and a mix of recipes using local ingredients. Additional copies of the booklet will also be available to community agencies and public health dietitians around the province.

This home economics project was funded by the governments of Canada and Manitoba through the Canadian Agricultural Partnership Ag Action Manitoba program in response to the increased financial pressures for families, the need for basic nutrition and cooking information, and a rise in food supply concerns in Manitoba.

In the late 1990s, the Association of Saskatchewan Home Economists (ASHE) created a website to honour the work of long-time Western Producer columnist Emmie Oddie upon her retirement.

Funds donated by readers and home economists from across Canada have continued to support the site though the Emmie Oddie Website Fund at the Canadian Home Economics Foundation/CHEF.

ASHE transitioned the site to MAHE in 2011 and it was given a new look. The mandate of the site is to provide home economics information of interest to consumers in Canada, and specifically on the Prairies.

Betty Ann Deobald is a home economist from Rosetown, Sask., and a member of Team Resources. Contact: team@producer.com.
