What is a Plant-Based Diet?
A plant-based diet focuses on whole, unrefined, or minimally processed plants, such as organic fruits, vegetables, tubers, whole grains, seeds, nuts and legumes. It excludes or minimizes animal protein, such as meat (including chicken and fish), dairy products, and eggs. This diet also exclude highly refined or processed foods like bleached flour, refined sugars and oil.
It’s very interesting that a vegetarian or vegan diet is often frown upon in the medical setting. I get lots of consults from concern pediatricians and parents.
A plant-based or vegan diet is almost synonymous as starvation or malnutrition or a cover for an eating disorder in teenagers.
Pediatricians freak out if parents is vegan, and the child is at eminent risk of malnutrition. Parents freak out if their child wants to be vegan. The consult is either for me to educate the family of a proper vegan diet or the parents want me to pursuede their child to change their mind.
Despite all the things we’re taught in school about risk of protein deficiency, iron deficiency, calcium deficiency, vitamin B12 deficiency in a vegan diet, I have never, in my professional life, see a vegan or vegetarian with any of these deficiencies.
I’ve seen iron deficiency in women, children and teenagers who eats a regular American diet. I’ve seen protein deficiency, calcium deficiency and calcium deficiency in very sick children who eats a regular American diet.
How Does the Plant-based Diet Work?
To understand how the plant-based diet works, we need to first understand the chemistry of the human body.
Don’t worry…I’m not going to pull out my organic chemistry or biochemistry hat and start lecture.
What I want to get to is that the human body is a giant water bag filled with interacting elements. The human body is kept alive and functioning by thousands of chemical reactions. Every single one of these reactions requires a “catalyst” to make the reaction happens.
And coincidently, these catalysts are minerals and vitamins found in lots of fruits and vegetables that God made for us.
So in order for the human body to function well to include staying focus, having energy, fight diseases, etc, we need all our chemical reactions to work at their best, which requires lots of minerals and vitamins.
Antioxidants found in fruits and vegetables also plays significant role in our body functions. Antioxidants help neutralize harmful free radicals and speed the healing process.
The living body is a dynamic structure where cells are constantly dying and being replaced with new ones. With proper nutrition (or ingredients) our body can build better replacement cells and tissues that works even better than the last.
And there’s something to say about “cravings”. We have always been right about cravings. It’s our body’s way to tell us that some important ingredients are missing. But we have been tackling cravings wrong all this time.
We’ve been told to drink water when you have a craving. Or try to figure the texture (crunchy, gooey) or taste (sweet or salty) of the food that you crave, and find the food with the right texture or taste to curb the cravings.
In fact, what our body is really craving for are nutrients. Vital nutrients, such as vitamins, minerals and antioxidants from fruits and vegetables, to facilitate life-supporting chemical reactions.
That’s the point we’ve been missing.
When your body is well-nourished, your cravings will stop. You can look at cravings as thirst or hunger. You need hydration when you’re thirsty, energy from food when you’re hungry, and nutrients when you have cravings.
Look at the United States, you think we’re a well-informed and well-fed nation. But look at our spending on healthcare, and statistics of people dying from lifestyle diseases, such as heart diseases, cancers, obesity, diabetes, etc.
The Healthcare costs well-exceeds the GPD. will eventually bankrupt this country. And 1.2 million deaths that could have been prevented.
All these are diseases of malnutrition (or overnutrition) and nutrient-deficiencies.
What About the Nutrients in Animal Protein? It’s true that animal protein does provide all 20 essential amino acids (building blocks of protein) in one source. However, it turns out animal protein is not the best or only source of protein or amino acid, or calcium, iron, zinc, etc.
High intake of animal protein (to include dairy and eggs) are associated with increased risk of certain cancers and chronic conditions.
According to the China Study, dairy products are not even a good source of calcium as we’ve been told by the Dairy Council.
It’s a big fat lie to get us drink loads of milk and eats tons of cheese so dairy farmers to make money.
In fact, the milk protein in dairy products increase risk of osteoporosis and osteopenia, and certain types of cancer. Studies have also shown that countries with the most dairy consumption also have the highest incidence of osteoporosis and osteopenia.
Red meat, as we know, increases risk of cardiac disease due to the oxidative effects of iron.
Despite the fact that plant protein is consider “incomplete”, it is the best source of protein. The human body does have 20 essential amino acids that we just can’t create on our own, and we need to acquire these essential amino acid from food that we eat. We’ve been told for decades that animal protein is ‘the best” source of protein because it provides ALL 20 essential amino acids. However, our body does not care where these amino acids come from.
Consuming animal protein to acquire these amino acids comes with a price – carcinogens, hormones, antibiotics, free radicals, etc. Therefore, animal protein should be consumed sparingly, such as once a week.
In Dr. Weston’s book Nutrition and Physical Degeneration, he discovered that native cultural diets that are free from modernized western influence has the most profound physical outcome, and that these native people consume a plant-based diet composed of mostly food found in their native environment and animal protein are consumed about only once a week.
Assuming you’re eating a wholesome plant-based diet with a variety of unprocessed fruits, vegetables, nuts, beans, seeds and whole grains, you’re guaranteed to have all your essential amino acids complete.
