Your body is made up of thousands of minerals, vitamins, enzymes, and other elements, but there is one nutrient that makes a powerful contribution to the formulation and function of almost every body part. Have you guessed what it is?
The Power of Protein
In a healthy human body, protein is present in proportions second only to water. It makes up approximately 17% of your body mass and has a direct effect on almost every organ and metabolic process. For this reason, many body-builders work to increase their protein intake because it has a noticeable effect on muscle growth. A deficiency in protein can have the opposite effect. After years of research in nutritional science, nutritionist Adelle Davis noticed the following symptoms of protein deficiency in her patients:
- Stooped shoulders and hunched posture
- Cracked, peeling fingernails
- Protruding abdomen
- Low blood pressure
- Sunken chest
- Flat feet
- Anemia
A combination of several or more of these symptoms could leave one looking and feeling shorter, smaller, and weaker. Fortunately, it is not difficult to reverse the symptoms of a protein deficiency; simply scrutinize your diet and make sure it is well-rounded with healthy portions of protein.
Sources
The amount of protein one should consume daily varies from person to person. Age, weight, and lifestyle can affect your daily requirements. A sedentary woman in her 50s who weighs 140 pounds may need considerably less than a heavy-set young man with a very active lifestyle. How much protein do you need?
At the time Adelle Davis was writing her book, the Food and Nutrition Board of the National Research Council recommended these amounts:
Children | Teens | Adults |
---|---|---|
Under 12 years | Over 12 Years | |
1-3: 40 grams | Girls 13-15: 80 grams | Men: 70 grams |
4-6: 50 grams | 16-20: 75 grams | Women: 60 grams |
7-9: 60 grams | Boys 13-15: 85 grams | Pregnancy: 85 grams |
10-12: 70 grams | 16-20: 100 grams | Lactation: 100 grams |
However, she also notes:
If one’s diet has been deficient in protein for some time, an intake of 150 grams or more daily is probably advisable for a month or more.
A rule of thumb given by some is to consume 20% – 30% of your daily calories in the form of protein to keep your body functioning optimally, inside and out. (Others recommend slightly lower percentages with high percentages of healthy fats). It is not difficult to incorporate protein into your diet. Plenty of foods provide healthy amounts of protein.
