When choosing your “better” protein source, it depends upon what you mean by the word “better”. Certain proteins are more concentrated than others. Beans, for example, are 20% protein, but eggs are 34 % protein, and nuts are less than 20% protein. Each of these foods have their own unique nutritional strengths beyond being a protein source – like fiber, healthy fats, and phytonutrients.
Protein from animal sources provide complete amino-acid profiles, while plant based proteins do not. Therefore, if you are a vegetarian or vegan, you need to make sure you are diligent in consuming enough proteins and amino acids. Plants contain less concentrated protein, so if you do have a plant based diet you will have to consume more volume to get your daily requirement, and eat a wide variety of whole foods to get all your essential amino acids.
Research Your Food
One thing to keep in mind is the potential toxins lurking in protein-rich foods. Consider purchasing non-GMO products, organic, and wild proteins free from artificial hormones and antibiotics. Look for fish lower in mercury and other heavy metals such as tilapia, salmon, freshwater trout, sardines, catfish, and sole.
Does Protein fuel Cancer?
Recent studies do suggest that there may be a connection between cancer and high protein intake in midlife. The key point is that this epidemiology study can only find associations, but cannot prove cause and effect. It is suspected that the cancer association could be due to toxins that make their way into conventional meat production. Many factory-produced meats come from animal fed diets high in GMO grain and soy, which is low in omega-3 fats and high in omega-6 fats. Omega-6 fats can fuel inflammation. It is known that chronic inflammation provided a landscape tolerant to malignant cell growth.
In other words, eating large quantities of low-quality meat can fuel inflammation or cancerous cells you may already have in your body.
Beware of chemical preservatives in conventional processed meats.
On the other hand, an animal protein rich diet from free-range, pasture fed sources which deliver omega-3 fats and other whole/organic foods, is much safer.
The whole picture is what individuals really need to look at. A complete diet, lifestyle choices, family history, and preexisting problems are all fuel to possible ailments and disease.
