If you’ve been watching your health and nutrition, you’ve no doubt wondered if you were getting enough protein.
Before answering that question, it’s important to understand what proteins are, and how they function in our bodies.
Proteins are Macronutrients, along with Carbs and Fats.
Proteins are made up of amino acids.
Once consumed and digested, the body breaks apart the amino acids, and then they are reconnected to form structures such as: bone, skin, muscle, organs, hair, and nails.
They are also used in other areas and functions of the body that we are not as aware of, such as enzymes, hormones, hemoglobin, the immune system, repair, brain function, genes, and much more.
The amino acids from proteins also help vitamins and minerals to be utilized properly.
Complete Proteins/ Incomplete Proteins
There are Complete Proteins and Incomplete Proteins.
Complete means that we are getting the full profile of amino acids essential to us.
Any time we say essential in nutrition, it means that the body cannot synthesize it and we need to get it from our diet.
We get Complete Proteins from meat, fish, eggs, and dairy.
We get Incomplete Proteins from legumes, vegetables, grains, nuts, seeds, and vegetables.
So, if you have decided to be vegan (which is a good way to save the planet), it is very important that you combine foods to get the full profile of essential amino acids.
A deficiency in any essential amino acid can lead to serious illnesses.
These are just a few of the combinations:
- almonds / buckwheat
- barley / kidney beans
- corn tortillas / beans
- lima beans / brown rice
- cauliflower, spinach / cashews
- hummus / Pita bread
- mixed vegetables / pumpkin seeds
Do you notice some traditional combinations?
Generally, if you combine beans, whole grains, nuts, and seeds you will get the compete profile of the essential amino acids.
A disruption in the synthesis of essential amino acids can also be caused from pollution, alcohol, processed food, smoking, drugs given to animals that provide us with meat sources, and pesticides
If you have been reading my blogs (are you?) you will recall that in my “Why Do We Need Carbs?” post, I mentioned that carbs were the primary source of energy, the secondary source being fat. If the diet is low in carbs and fats, the body will break down tissue. The body does not store amino acids in reserve the way it stores fats.
There are two other important functions of protein in the body. One is to maintain fluid/salt balance. This is how your heart, lungs and nervous system functions properly.
The second function is maintaining Alkaline/acid balance so that the blood is kept at a Ph of 7.5.
Protein deficiency can happen if we are not consuming enough protein or not digesting it properly.
A deficiency in proteins would most likely occur because of starvation. Causes include: unavailable proper nutrition, eating disorders, alcoholism, an undiagnosed digestive disorder, or general poor digestion.
Any of these causes could lead to weight loss (tissue loss), water retention (extremely bloated abdomen), general weakness, hair loss, and an inability to heal wounds.
If one is consuming too much protein, they run the risk of developing kidney stones: both uric and calcium stones.
Kidney stones occur when calcium is released from the bones. Now remember, we need to keep calcium in the bones in order not to develop osteoporosis, therefore Osteoporosis can also be a risk factor in a high protein diet.
There is an abundant selection of protein powders on the market.
It is important to choose the right one according to the results one needs or wants.
Is it a meal replacement?
Is it for bulking up? This one is for those building muscle (and hopefully accompanied by weight training) otherwise – guess what? – you’ll just get fat.
Read labels carefully when choosing a protein supplement to make sure you are getting one without additives, food colouring, or ingredients you may be allergic to.
The average adult needs about 0.37 gr per lbs weight or 0.08 gr. per kgs weight. That’s about:
- 56 grams per day for the average sedentary man.
- 46 grams per day for the average sedentary woman.
Pregnant and lactating women need more
A 4-ounce serving of grilled chicken breast, that’s a little bigger than the palm of your hand, has 35 grams of protein.
So, those of you on a high protein diet – are you overdoing it?
Those that have hypoglycemia (low blood sugar) have a higher requirement for protein.
During any kind of illness or injury, as the body is trying to repair itself, our need for protein increases.
If you need more information about your specific protein needs, consult with a nutritionist.
They will take your whole health and physical needs into consideration to make the proper recommendations.
If you are an athlete, consult with a nutritionist that specializes in sports nutrition, for the same reason as above.
Now, please remember, this blog is NOT to promote a high protein diet.
As Michael Pollan says, “Eat food (not too much), mostly plants.”
