Plant-based protein sources
LOOK at any part of your body: You are made up of proteins, every nerve, muscle fibre, skin cell, organ, hair, nail, enzyme, immune cell, blood vessels, every one of your 37.2 trillion-plus cells is made up of proteins.
Protein is one of the three major macronutrients, along with carbohydrates and fats, that is necessary for functionality, growth and repair of all your life-sustaining systems.
Contrary to some beliefs, protein is required for much more than muscle building. Proteins are literally the building blocks of life. This, in part, explains why modern society is obsessed with protein intake.
There is some debate regarding how much is required for sustaining health, but no matter how much we think we need, the fact is, proteins are essential nutrients.
If you are interested is weight loss, it is known that protein:
• Has been shown to be the best of the three macronutrients to increase fullness;
• Increasing protein to 30 per cent of total caloric intake adds to greater feelings of satiety and fullness;
• Higher protein diets result in test subject consuming 441 fewer calories per day;
• Yes, higher protein and low carbs does help, but eliminating carbs has been shown to lessen overall health and shorten lifespan.
Benefits of plant proteins
The big difference between many other organic molecules and protein is nitrogen. Only plants can extract nitrogen from the atmosphere and combine it to produce proteins. Plants are the origin of all nutrition on the planet, protein included, and natural plant — source protein is the cleanest, safest and healthiest available.
There are advantages in having plant-based proteins in your diet, such as:
• A diet higher in fibre, essential for gut health and lowers the risks of cardiovascular disease;
• A wide spectrum of essential micronutrients, needed for immunity and all other body functions;
• Increased antioxidants, fighting the daily threat of your free radical-triggered cell damage;
• Researchers have confirmed that diet of plant-source proteins or a diet consisting of days with animal-source proteins and days with plant-source proteins is beneficial to overall health and longevity;
• Significantly less saturated fats than animal source proteins;
• The World Health Organization (WHO) reported that processed red meats are carcinogenic (cancer-causing);
• People on a predominantly plant-based diet tend to have healthier lifestyles and are more mindful of their foods (still, remember to avoid processed plants, flour and refined sugars);
• Plants can and do provide enough protein and iron;
• Replacing one to two servings of animal-based protein with plant-based protein can reduce cholesterol markers by roughly five per cent;
• Better hair, nails and skin; and
• Increased plant and decreased animal agriculture is highly beneficial to the environment and climate.
Opting for all plant-based eating at least two days per week will positively affect your wellness. To help you get started, I have compiled a list of plant protein sources (with a few animal sources for comparison), most of these items are completely natural, a few are mildly processed, and even fewer are manufactured.
Important point of note:
• Compared to the available animal protein, some plant sources may be relatively high in: Calories — the same quantities of plant protein will usually have more calories than animal sources; carbs — animal proteins are not carb sources but plant proteins are also sources of carbs, therefore, your macronutrient ratios must be adjusted for plant protein sources; sugar — plant proteins usually have sugar, sometimes significant amounts, so remember to include their sugar content when keeping below your safe 25 grams of sugar per day maximum.
• Most plant sources are high in micronutrients, but it is a good idea to tend towards those with good mineral and iron content.
• If you choose a full vegan diet, it is advisable to take a B12 supplement as there is no plant sources which provides a reliable supply of this highly essential vitamin. However, they are artificially fortified products.
There have also been cases of non-supplementing vegans who appear to get sufficient dietary B12, perhaps from insects, worms, eggs, larvae and other animal materials often found with vegetables, in any case, make regular medical check-ups a part of your yearly routine.
In choosing a plant protein source, attempt to focus mainly on plant sources with the higher protein levels, and relatively less calories and carbohydrates.
And, always remember, utilising the widest spectrum in plant source proteins is strongly advised, as the nine essential amino acids (the building block of proteins) are practically never found in any one plant source. The last thing you want is for even one negative to outweigh the many benefits.
