To eat or not eat meat

After watching a program from Norwegian television (NRK) called Line fikser maten (Line makes food), I am even more convinced that cutting out meat and fish from our diet is good for both my body and the planet.

I first became aware of the problems caused by the consumption of meat when reading, Diet for a Small Planet, back in the 1970s. The author, Frances Moore Lappé, was concerned that eating meat was not sustainable on our planet and she showed how one could use plant products to supply the protein we humans need to consume. She showed how to combine foods to create good nutrition and give enough protein on a daily basis. She also provided lots of recipes so that one could get started with creating a new healthier diet.

Published by Friends of the Earth and Ballantine Books, New York, 1971. My copy is from the 12th printing in 1974.

Already at that time, I went over to a diet that used proteins from plant products and reduced my intake of meat, fish and poultry. It has since been shown that one doesn’t need to complement foods in the way that Lappé suggested to get adequate protein, though one should still think carefully about which types of foods should be eaten during the day.

In 1980, my husband and I moved to Norway and had very little money to live on. We lived on the coast, so fresh fish was affordable, but meat was not. We rarely ate meat, except for the occasional ground beef. Poultry was also not nearly so common back then and not particularly cheap, at least for our income level. A wide variety of legumes was not available either, so we lived on quite a restricted diet. I never felt that we had poor nutrition though I do remember trying to buy everything on sale, especially canned goods.

Once we started working in Norway, and our income improved we also started eating more meat and poultry. The cost of meat became relatively cheaper and certainly poultry became cheaper and easier to get hold of. Over the last forty years, the availability of a variety of food has improved and imported food has became much more common.

Now we eat a wide variety of legumes, most of which are imported from Asian countries. Though I do prefer to buy vegetables that are grown locally, not everything is in season year round. As an example I was able to buy the first locally produced tomatoes today and they haven’t been available for several months. Much of our fresh produce comes from Spain, Israel or South Africa.

We live in an agricultural area, surrounded by farms. We have an egg farm as one of our nearest neighbors and we walk up there to buy farm fresh eggs. Some of the farms nearby are meat producers, either beef or pork. Potatoes, carrots and other vegetables may come from neighboring communities. But bananas, oranges and grapefruit are still not grown in Norway. However with climate change and the increasing use of greenhouses to produce plants, there may come a change in what is locally grown in the future.

Nutrition – Proteins

When we want to eat healthily, we have to get the correct combination of food types. There are three main types of food: proteins, carbohydrates and fats. This article is about proteins.

We need to eat protein as part of our diet on a daily basis. It is one of the building blocks of the cells of our body. Our body uses the proteins in the food we eat to build muscle and to provide energy for our use. Protein has the same number of calories per gram of food as carbohydrates, 4 kcal per gram (17 kJ).

A lot of research has been done so that it is now known about how proteins work in the body, how they are converted, etc. The chemistry of this is beyond the scope of this article and I suggest anybody that is interested in learning more about that to look it up on Wikipedia.

There are nine essential amino acids which humans must obtain from their diet. Animal proteins will usually include all nine and are thus considered “complete” protein. Plant proteins may be missing one or two of these proteins so that foods have to be combined to make sure one gets all the amino acids every day.

My interest in proteins has to do with getting sufficient in my diet. Most people will think of meat, fish and eggs as the normal sources of protein, but there are many plant sources as well, such as lentils, chick peas, black-eyed beans, almonds and sunflower seeds. Understanding the sources of protein in the foods we eat will help us plan a better diet, at perhaps a lower cost.

Where I live in Norway, meat and fish, as well as the processed products made from them are expensive. My husband and I have now reduced our consumption of meat and fish to about once each a week, and on the other five days of the week rely on other good sources of protein.

How much protein you need in a day depends on your height, gender, age, muscle mass and lifestyle (such as sedentary or active). According to healthline.com the average male needs about 56-91 grams of protein and the average female needs about 46-75 grams of protein per day.

Let’s look at the protein content of various types of food. The numbers given below are grams of protein in 100 grams of food. My source is The British Nutrition Foundation (https://www.nutrition.org.uk) or the packaging of the items I have in the house. Remember that many packaged foods will give you the amount of protein per 100 gr on the label.

Animal foods:

  • Beef – 31 gr
  • Pork – 31 gr
  • Chicken – 32 gr
  • Salmon – 24.2 gr
  • Tuna – 23.5 gr
  • Cod – 20.8 gr
  • Eggs – 12.5 gr
  • Whole milk – 3.3 gr
  • Cheddar cheese – 25.4 gr
  • Cottage cheese – 12.6 gr

Plant foods:

  • Red lentils – 23.8 gr
  • Chickpeas/garbanzo beans – 8.4 gr
  • Kidney beans – 6.9 gr
  • Black-eyed beans – 23.1 gr
  • Alubia beans – 22.5 gr
  • Peanut butter – 26 gr
  • Sunflower seeds – 23 gr
  • Pumpkin seeds – 25 gr
  • Sesame seeds – 18 gr
  • Almonds – 21 gr
  • Pecans – 9.2 gr
  • Hazelnuts – 15 gr
  • Walnuts – 15 gr

Remember that not all servings are of equal size. I hope you would never have 100 gr of peanut butter at one sitting, though 100 gr of meat is common. As you can see, many plant foods give a reasonable amount of protein.

Black-eyed beans

In North America these are also called cowpeas or black-eyed peas but they are actually beans.

Here are some of the health benefits of black-eyed beans:

  • 23.5 grams of protein per 100 grams of dry seed
  • a good source of dietary fiber (8 gr)
  • 353 kcal (1478 kj)
  • gluten-free
  • 58.2 gr of carbohydrates but only 1.4 grams of sugar
  • excellent source of B-vitamins and folates
  • source of minerals such as calcium, copper, iron, magnesium, manganese, phosphorus, selenium and zinc
  • low in cholesterol
  • good source of potassium

I use one deciliter of dry beans for two people. This weighs about 90 grams so will give about 160 kcal for each person.

I soaked the beans overnight in water and then cooked them for about 30 minutes. They were soft enough to eat, but still a bit crunchy in a salad.

Black-eyed beans are also excellent in soups, but if overcooked they become pureed. You can use them in stews, or mash them and use them in patties.
