Chia Seeds

It is a myth that you have to eat animals to get enough protein. Nor do you have to eat lots of extra protein to build muscle, if muscle building is your goal. All proteins are made from a collection of 25 amino acids – the building blocks of the body; however, all 25 can be made from only eight essential amino acids.

As well as being essential for growth and repair of body tissue, amino acids are used to make hormones, enzymes and antibodies required for immunity, as well as neurotransmitters (chemicals of communication) such as adrenalin and serotonin, which control your stress response and mood respectively. Both the quality of the protein you eat, determined by the balance of these eight essential amino acids, and the quantity you eat, are important.

If you are building a house, you need a certain amount of bricks, cement, wood and so on. Imagine each essential amino acid as one of these building components. If one is lacking, you can’t build a house.

Having foods, or food combinations, that provide close to the perfect balance of amino acids is important. A food that naturally contains all the eight essential amino acids is called a complete protein. Of course, animal protein is complete protein but, in turn, it was made from what the animal ate. A vegetarian animal, such as a sheep, derives all its protein from vegetable sources, such as grass. The same thing is true with fish through the food chain: a carnivorous fish, such as mackerel, eats a smaller fish, which ate a tiny organism called plankton, which derived its protein from algae or seaweed.

Traced back in this way you can see that all protein ultimately derives from vegetable protein, which illustrates why vegetable protein is perfectly appropriate as a source of protein for everyone. Let’s start by examining which foods give you the best quality of protein before we look at how much you need, since the better the quality of protein the less quantity you will need.

It’s like building a house with less waste because you have everything you need and no more. High-class proteins The best foods to eat for protein are not necessarily those that are highest in protein to the exclusion of everything else. We don’t just eat food to get one specific nutrient. The pros and cons of a food’s other nutritional constituents have to be taken into account to enable us to make an informed decision about the healthiest foods to eat. Comparing animal and vegetable sources of protein is interesting: for example, a lamb chop provides 25 per cent of total calories as protein and 75 per cent as fat, much of which is saturated fat.

Therefore, even though it provides a lot of protein it also contains a lot of fat. Chia seeds provide only 18 per cent of total calories as protein, so they might be deemed a lesser source of protein, but what else do they provide? Forty-seven per cent of calories in chia is fat, primarily polyunsaturated fats, and the remainder (35 per cent) is in the form of slow-releasing carbohydrates (those carbs that release their sugar slowly, as I will explain in detail in Chapter 7). Also, although those carbs count towards the calories, much of it is in the form of insoluble fibre, which is the best kind of fibre, plus magnesium and other nutrients. So, chia seeds are a good all-round food.

I explain the protein options in more depth in my book Optimum Nutrition for Vegans.
