Despite the availability of nutritious foods, much of the modern developed world today eats a much less than optimal diet.
In fact, the incidence of heart disease and cancer is higher in more developed countries and still kills about 80% of all adults, despite the fact that the nutritional causes of these illnesses have been explained by scientific studies.
Unfortunately, our society has developed to the point where half of all caloric intake today comes from refined or processed foods and about 40 percent from animal products. Both processed food and animal products lead to heart disease and cancer, according to scientific literature.
The most commercially successful diet books in our country appeal to America’s love-affair with saturated, fat-rich animal products and still leave the public with a relatively dangerous solution to their growing waistlines.
These books encourage a higher percentage of animal products in people’s diets in spite of the preponderance of evidence showing the links to heart disease and cancer.
There are three main problems with diets that contain significant amounts of animal products:
More than a thousand well-designed studies have led to all major health authorities around the world to conclude that saturated fat is a leading contributor to high cholesterol, heart disease, and many cancers. In spite of that, some still believe the earth is flat, and saturated fat is not harmful.
Fat soluble petrochemicals such as PCB’s and dioxin, as well as other toxic elements such as mercury are transferred to humans predominantly via the fatty portions of fish, dairy, meat, and poultry and in that order.
Fatty fish that are rich sources of omega-3 fats are also typically heavily contaminated with harmful pollutants.
Animal products contain no fiber, and almost no antioxidant vitamins such as vitamins C, K, E and folate. They also are lacking in all the anti-cancer phytochemicals, bioflavonoids, lignins, and carotenoids that are so essential to protect us against chronic illnesses, immune system disorders, and a premature death.
With animal products occupying a major caloric percentage of the diet, less remains for natural, unrefined plant produce, nutritious foods essential to our health.
The inclusion of sugar, white flour, oil and other low-nutrient calories in an omnivorous diet virtually guarantees phytonutrient deficiency and the occurrence of late life cancer.
So the low levels of certain essential nutrients are inevitable, unless an omnivorous diet is carefully designed to include substantial amounts of fresh fruits, vegetables, beans, raw nuts, and seeds to supply crucial food elements for optimal health.
The amount of produce necessary to afford a considerable degree of protection would automatically necessitate animal products be a significantly smaller percentage of ones dietary intake, rather than a main portion.
After that, the type of animal products chosen is crucial to minimize their potential harmful effects. The animal products that are lowest in saturated fat are egg whites, low fat fish, skinless white meat turkey, and chicken. The highest saturated fat animal products are butter, cheeses, and red meat.
Because animal products do not contain significant omega-3 fat it is important for those omnivorous diet to consume walnuts, flax, hemp, and other plant sources of omega-3.
The valuable omega-3 fats should not be derived exclusively from the regular consumption of fatty fish, which are such a polluted food. Instead, I recommend the lower fat (less polluted) fish such as flounder, sole, and tilapia and using the cleaner, plant sources of omega-3.
In addition, a multivitamin and a DHA supplement would still be a good idea, for the assurance that optimal levels of these nutrients are met.
Is a vegetarian or vegan diet safe for children?
Parents often ask me whether their children should be eating a vegetarian or vegan diet. A diet optimally designed for the human species, would naturally be ideal for the children of that species too. There are no special needs children have that would make them require a different diet.
Even at the time of rapid growth and brain development the optimal supply of energy and essential fats can be met by and appropriately planned vegetarian or vegan diet.
According to the American Dietetic Association and the Institute of Food Technologists vegan diets can provide adequate nutrition for children.
In May 1998, the seventh edition of Dr. Spock's Baby and Child Care was published. In it, Dr. Spock recommends a vegan diet for children. Dr. Spock was concerned that the diet we fed our children, rich in animal products and dairy fat set them up for adult disabilities and a premature death.
He wasn’t wrong. But this sparked a long overdue discussion about the scientific and practical issues of optimal diets for children.
Clearly children of all ages need an adequate supply of healthy fats to fuel their growth and energy needs and for brain development.
Some people believe even a B12 supplemented vegan or vegetarian diet would not supply enough essential fats for comfort. This could be a concern if the diet is essentially carbohydrate-based, comprised of foods such as bread, potato, rice and fruit.
Conversely, raw nuts, seeds and avocados are rich in protein, fat, vitamins and minerals. Whole nuts, such as peanuts, should be avoided in young children as the shape makes them possible to get stuck in a toddler’s windpipe, if not chewed. But nuts can be safely utilized in the diet after one year of age utilizing nut butters, dressing, sauces and desserts to meet these concerns of fat adequacy.
Nuts are rich in protein and also a clean source of nourishment as they grow on deep-rooted trees and do not contain chemical residue. Avocados are appropriate food for infants starting at six months and can be mashed with bananas and mixed with other foods to add a nutritious fat source.
The addition of fortified soy milks and tofu, beans, and green vegetables assures complete nutrition for toddlers and children on vegetarian diets.
Of course, informed parents know that if children are to maximize their intellectual and health potential they must be breast fed. Breast feeding should be continued to at least the first and preferably the second birthday to maximize benefits at reducing cancer incidence for both the baby and the mother doing the nursing.
The real question is : Is an omnivorous diet safe for children?
Clearly the omnivorous diet that most children consume today is particularly dangerous to their future health.
The most recent scientific evidence is both overwhelming and shocking—apparently what our parents choose to feed or not feed their children during childhood has a greater effect on the cause of certain cancers than dietary intake over the next 50 years.
Today it is well recognized that our children eat less than 2% of their diet from natural plant foods such as fruits and vegetables.
American children move into adulthood eating 90% of their caloric intake from dairy products, white flour, sugar, and oil.
Then many develop autoimmune illnesses as young adults before heart disease and cancer strikes later. Diseases of nutritional ignorance flourish, but they have not been connected to their cause—childhood diets—until now. The diet rich in cheese, whole milk, white flour and sugar is implicated.
High dairy fat and animal food consumption in childhood assures unnaturally high levels of hormone promoters that raise our children’s blood level of estrogen and testosterone, induce an earlier maturity, and initiate changes that promote adult cancers.
It is well accepted that an earlier puberty significantly increase the adult risk of both prostate and breast cancer. Animal fats (especially dairy and fish) also contain contaminants that place children at increased risk.
One could make an omnivorous diet safer if dairy fat were removed, if one avoided the potential pollutants in fish, if processed food were significantly limited and if an abundance of produce were consumed.
I would rather a young child added eggs to her diet than fish or dairy, because of the potential for transmission of chemicals mercury and PCB’s in the fish and dairy.
Therefore I encourage consumption of a carefully planned vegetarian diet or one that includes a small amount of animal products, perhaps 10% of total calories or less, rather than 40 -60 % that children eat today. An animal-product-rich omnivorous diet cannot be considered nutritious food or called healthful.
If one is to utilize animal products in their family and children’s diet they should only choose low-fat or nonfat varieties of dairy products, if they are included in the diet at all.
I still recommend substituting nuts, seeds, and avocados as the major sources of fat in the diet.
Fruits, vegetables, avocados, nuts, seeds, beans/legumes, and whole grains are the optimal foods for children. Here are some of the long-term advantages of plant-based diets:
Vegetarian diets prevent and reduce high blood pressure Cholesterol levels are much lower in vegetarians
Cancer rates are much lower in vegetarians
Vegetarians are leaner and have less obesity in adulthood
Plant-based vegetarian diets encourage a later menarche, which has been shown to be associated with reduced risk of prostate and breast cancer
Both vegetarian and omnivorous and diets can be made healthful or harmful; nutritious food choices, wise supplementation and nutritional sophistication will make the difference in the type of diet you choose.
Following a strict vegetarian diet is not as important as eating a diet rich in fruits and vegetables. Inclusion of high nutrient produce, including nuts, seeds, fruits, vegetables and beans are an essential part of every healthy diet.
