Fish Oil vs. Cod-Liver Oil

Many people today are getting extra omega-3 fatty acids in their diet with fish oil. Omega-3s have decreased in our diets today largely because of vegetable oils and corn-feeding of our livestock. From beef to chicken and now, even our farm-raised fish, unless a person chooses to get their food from a farm co-op that pastures their animals, foods that used to have a balance of omega-3 to -6 fatty acids are now overabundant in omega-6. In fact, because of today’s foods, omega-6 fatty acids can dominate omega-3 fatty acids by as much as between 20 to 1 or 30 to 1! (Another important reason to purchase pastured foods.)

An overabundance of omega-6 fatty acids can sometimes be a factor in inflammation as it may cause an imbalance in the production of important hormones called prostaglandins. Because of this, many people turn to omega-3-rich fish oil supplements like salmon oil. These are beneficial, but when you take a high quality cod-liver oil you will not only get the omega-3 fatty acids, but you will also get both vitamins A and D, which are critical to nutrient absorption. Dr. Weston A. Price’s research of healthy populations worldwide found that these cultures consumed 10 times the amount of vitamin A and D compared to diets of his patients in the US–in the 1930s! So that figure now would be much higher today considering how depleted our food supply has become.

Unfortunately, commercial cod liver oil is not the  always the best choice, as the natural vitamin A and D has been removed in processing and a synthetic version of these vitamins is put back. The Weston A. Price Foundation recommends fermented cod liver oil from as an excellent choice for this supplement. It is the only cod liver oil in the world that is  made in a traditional way. It is also much more dense in vitamin A and D than commercial brands so the dose is much smaller.

Cod liver oil has been recorded as being an elixir for good health by cultures all over the world as far back as in the Roman empire. Even your great-grandmother took cod liver oil! So take your cod liver oil!! And while you are at it, take it with high-vitamin butter oil, which was Dr. Price’s prescription for healing (also available at

What does the government and media say are the top 14 foods?

According to the government and media health pundits the top 14 foods are:

  • Beans
  • Blueberries
  • Broccoli
  • Oats
  • Oranges
  • Pumpkin
  • Salmon
  • Soy
  • Spinach
  • Tea (green or black)]
  • Tomatoes
  • Turkey
  • Walnuts
  • Yogurt

This uninspiring list reflects the current establishment “angels” (anti-oxidants and omega-3 fatty acids) and “demons” (saturated fats and animal foods). Unfortunately, a diet containing only these foods is a fast track to nutritional deficiencies.

All proteins are not created equal.

When you are deciding which foods to eat, choosing a diet where most of the foods give you the most nutrients per gram makes good sense for building and maintaining good health doesn’t it? In fact Dr. Weston A. Price found through his research of healthy populations worldwide that “All disease comes from malnourishment.” (see

Next, it makes sense to choose proteins that are easy-to-digest so that the nutrients that they contain are available to the body, which was another aspect of the work that Dr. Price did. When he sought to find cultures of people that had perfect health, he was hoping that he would find one that was vegetarian as he believed in the principle of vegetarianism. Unfortunately, he was very disappointed to find that cultures whose protein sources were from plants displayed degenerative conditions. This is because proteins from legumes, nuts and seeds are difficult to digest and do not have the nutrient-density of animal foods as they do not have the full array of amino acids.

As you can also imagine, fractionated proteins like “whey protein” and other protein powders are highly processed, difficult to digest and are therefore poor choices for nutrient-dense foods. These are among the “new-fangled” food  inventions of today that rob your pocketbook and promise results, when in fact, they are not real food!

So shopping for foods that will comprise a good diet is at best confusing when there is so much conflicting health advice–especially when we have been literally brainwashed into believing that a healthy diet is low-fat and high-fiber.

How can we go about making an educated choice about what proteins to include in our daily fare. If we are looking at nutrient-density alone, the foods highest in nutrients are not only organic, but they come from animals eating their natural diets. So finding a source of eggs, dairy, meat and fish from good sources is critical to good health as there is a remarkable difference in the nutrients in for instance, eggs from a pastured chicken and even an organic egg from a “vegetarian-fed” chicken (chickens are not vegetarian by the way–their natural diet is comprised of bugs and worms). Price also noted that in all cases healthy cultures ate ample amounts of traditional fats with proteins like butter, meat with its fat, cream, lard, coconut oil or palm oil.

Also, all healthy cultures that Dr. Price studied had sacred foods for good health, couples who wanted to conceive and growing children.  One of the sacred protein foods that they consumed was organ meats like liver. Liver from a grass-fed cow or other pastured animal is one of the most nutrient-dense animal foods that you can eat. If you consume liver just once a week, you will greatly magnify the nutrients available to your body for building and maintaining good health. Some people think the liver stores toxins, but in fact it acts as a filter. However, it is also very important to get liver from good sources-see for a list of local Weston A. Price chapters in your area to locate farm coops that carry naturally raised foods.

Below is a fascinating list of the comparative vitamin content of various kinds of liver. From this list, you will see just what nutrient-density really means.

Carbohydrate addictions–it’s not all in your head.

Food addictions can be much more than just talk–they can be real biochemical dependencies that may be signs of health issues. Today, many people are addicted to carbohydrates, like breads, chips, cookies, candy, soda pop, etc. From the aisles of “organic” junk food products in our health food stores to literally hundreds of  junk foods that sit on the shelves of grocery, discount and countless other stores, and the billions of dollars that are spent on advertising these products especially to growing children, it is almost unfathomable that these types of “foods” were by-and-large created in the last 60 years. But why do people crave them?

Because there was no refrigeration, our ancestors consumed many foods that were preserved through lacto-fermentation like yogurt and kefir and fermented vegetables, such as traditionally prepared sauerkraut and pickled beets, which contained probiotic bacteria that helped to maintain a healthy digestive system. With refrigeration and the industrialization of our food supply we stopped making these probiotic foods and started consuming more and more new-fangled food creations. These new fascinating “foods” have wreaked havoc on our digestion and the health of our population as they are very nutrient deficient and hard to digest.

When we consume foods that are hard to digest–even organic foods, digestion slows down in our stomach and stomach acid diminishes. Low acid in the stomach can cause an overgrowth of candida . In addition, without adequate stomach acid, the gluteomorphine proteins in gluten containing grains may not to be properly broken down before they reach the small intestine. In the small intestine the resulting byproduct of poorly digested carbohydrates is alcohol and acetaldehyde as well as morphine-like chemicals. We all know that alcohol and morphine are extremely addictive substances. Acetaldehyde is a very toxic chemical that can bind itself to proteins and make them unusable as nutrients. Therefore, carbohydrate addiction is a real chemical problem and without healthy digestion, candida overgrowth and poor gut flora will ultimately cause intestinal damage and malnourishment.

The best way to end the candida cycle and food addictions is to focus on eating a diet of easy-to-digest, nutrient-dense foods. Foods with real nutrients will eventually help you end the cravings as digestion and nutrient absorption improves.

Do you get hungry two hours after eating breakfast?

If you are getting hungry two hours after eating breakfast, you may be choosing the wrong kind of foods for your morning meal and this may be a sign that you have absorption problems as well. Let’s look at both of these important issues.

First, a breakfast of cereal, toast or a bagel with non-fat spreads and a piece of fruit may not be the breakfast of champions! For years before I got deathly ill with a digestive disorder, my favorite breakfast was bagels, no-cholesterol “buttery flavor” spread and a piece of fruit. Another choice was a bowl of cold cereal. However by 10AM, I was very hungry again. This is not good. A healthy breakfast is not one that would leave you hungry in just a few hours.

Instead, a breakfast with higher amounts of protein and fat from traditional foods will literally nourish you until the afternoon and will offer far greater levels of nutrients. In our book we recommend a few great breakfasts that besides being nutrient-dense, will also help improve digestion. Smoothies made with 16 oz. whole fat kefir or yogurt (preferably raw milk from grass-fed animals), 2-4 raw egg yolks (from pastured chickens–not commercial eggs), fruit and 1 T. coconut oil are a fabulous breakfast. Another is old fashioned bacon (organic, no-nitrate) and eggs (from pastured chickens). Nutrient density is the key to building optimal health and maintaining blood sugar meal to meal. Nutrient-dense foods have ample high-quality traditional fats, protein and carbohydrates.

However, another reason that you are hungry just two hours after eating may be that you are suffering from inflammation in your intestinal tract. Inflammation is usually caused from bacterial imbalances in the gut flora like a candida overgrowth. When inflammation is present, nutrient absorption will be hampered and a person will feel hungry very quickly after eating a meal. After years of malabsorption, malnourishment is sure to follow.

For optimal health we need eat foods that are high in nutrients and also those that will support good digestion. For more information on building health and healing with nutrient-dense foods see Performance without Pain and our new e-book on healing acid reflux.

What does the health of cats and humans have in common?

Concurrent pivotal  research in the 1930s by Dr. Weston A. Price and Dr. Francis Pottenger determined that there was a profound relationship between nutrition and fertility in both humans and cats. Dr. Price found that in the 14 healthy populations he studied, women had no fertility issues or problems in pregnancy or childbirth, and their children were very sturdy. In fact he noted that the Eskimo women had one healthy baby after another. However, people from these same cultures who had moved away and obtained access to “modern foods” –pasteurized milk, white flour, refined sugar and vegetable oils, had fertility and pregnancy problems, and the children born from these mothers had structural imperfections like narrowed faces and crooked and crowded teeth as well as health problems–the very same issues that he had seen in his own patients in the United States.

During this same time period, Dr. Francis Pottenger was working with nutritional healing for the treatment of tuberculosis and other diseases at the Pottenger Sanatorium in Monrovia, California. He always focused healing on a proper diet based on the principles discovered by Weston A. Price, and served liberal amounts of liver, butter, cream and eggs to his patients.

He also kept colonies of cats who had had their adrenal glands removed to help him determine how much adrenal cortex to give to his own patients. He found that when the cats consumed a species appropriate diet of raw milk and raw meat that they thrived from one generation to the next. However, if they received either a diet of pasteurized milk and raw meat, raw milk and cooked meat or pasteurized milk and cooked meat that the cats developed degenerative conditions. In fact, with these problem diets, in the second generation, the cats had narrowed faces and crooked and crowded teeth, and in the third generation, the cats could produce no more young!

These astonishing independent yet parallel outcomes between both Dr. Price and Dr. Pottenger can teach us the keys to the exponential percentage of fertility problems that we are seeing today. Both humans and cats who have superior nutrition will have no fertility problems and their offspring will be healthy. But when nutrition is inadequate, the first sign is in fertility problems, structural problems and the presence of health issues.

What we must wake up to understand is that widespread fertility problems are truly a sign of something very wrong with our foods and nutritional beliefs. And if we are really honest, by not choosing and supporting a supply of nutrient-dense foods, this lack of fertility really will ultimately translate into extinction. What both Pottenger and Price revealed can help us to be determined to help to turn the clock back.

Vitamin K-2–found in foods from pastured animals–is critical for proper calcium absorption and deposition.

Today we are seeing an exponential increase in health conditions like osteoporosis and atherosclerosis that are caused by poor calcium absorption or calcium going in the wrong places in the body–like in the arteries and organs and not in the teeth and bones.  This is partly due to a deficiency of foods that contain both vitamin A and D and also vitamin K-2, which is found abundantly in foods from pastured animals like raw butter and cheese. This vitamin works with vitamin A and D to promote the  proper deposition of calcium. Historically, when people consumed foods from naturally raised animals, these deficiencies were not seen. Dr. Price called this special vitamin “activator X’ as it worked as a “mortar” for the building blocks of vitamin A and D foods like cod liver oil to create the correct genetic expression of the skeletal structure. Here is an excerpt from the Weston A. Price Foundation website that further explains this principal:

In 1945, Dr. Weston Price described “a new vitamin-like activator” that played an influential role in the utilization of minerals, protection from tooth decay, growth and development, reproduction, protection against heart disease and the function of the brain.

Using a chemical test, he determined that this compound—which he called Activator X—occurred in the butterfat, organs and fat of animals consuming rapidly growing green grass, and also in certain sea foods such as fish eggs.

Dr. Price died before research by Russian scientists became known in the West. These scientists used the same chemical test to measure a compound similar to vitamin K.

Vitamin K2 is produced by animal tissues, including the mammary glands, from vitamin K1, which occurs in rapidly growing green plants.

A growing body of published research confirms Dr. Price’s discoveries, namely that vitamin K2 is important for the utilization of minerals, protects against tooth decay, supports growth and development, is involved in normal reproduction, protects against calcification of the arteries leading to heart disease, and is a major component of the brain.

Vitamin K2 works synergistically with the two other “fat-soluble activators” that Price studied, vitamins A and D. Vitamins A and D signal to the cells to produce certain proteins and vitamin K then activates these proteins.

Vitamin K2 plays a crucial role in the development of the facial bones, and its presence in the diets of non-industrialized peoples explains the wide facial structure and freedom from dental deformities that Weston Price observed.

By eating traditional foods from pastured animals, you can help protect yourself from common degenerative conditions. For more information on traditional diets, see our book at

Can the Body Convert Beta Carotene in Vegees to Vitamin A?

We have discussed the critical importance  of the vitamins A and D from natural sources. Dr. Weston A. Price found that without adequate amounts of these nutrients you could not absorb the nutrients from your foods no matter how good the diet. The best sources of these vitamins are from Green Pasture fermented cod liver oil, pastured animal foods like egg yolks, liver, butter, lard and from fish eggs. Healthy cultures consumed these foods liberally and yet today we are told to avoid most of these because of their cholesterol levels.

But what about getting vitamin A from the beta-carotene in vegetables? The following article by Sally Fallon discusses this issue.

Vitamin A Vagary

by Sally Fallon

This article has since been expanded and updated on the Weston A Price Foundation site as Vitamin A Saga

“Eat carrots for vitamin A.” Such statements, found in many popular diet and nutrition books, create the impression that the body’s requirements for this essential nutrient can be exclusively met with plant foods like carrots, squash, green leafy vegetables and orange colored fruits. The low fat school of nutrition benefits greatly from the fact that the public has only vague notions about vitamin A; for the family of water-soluble nutrients called carotenes are not true vitamin A, but are more accurately termed provitamin A. True vitamin A, or retinol, is found only in animal products like cod liver oil, liver and other organ meats, fish, shell fish and butterfat from cows eating green grass.

Under optimal conditions, humans convert carotenes to vitamin A in the upper intestinal tract by the action of bile salts and fat-splitting enzymes. Of the entire family of carotenes, beta-carotene is most easily converted to vitamin A. Early studies indicated an equivalency of 4:1 of beta-carotene to retinol. In other words, four units of beta-carotene were needed to produce one unit of vitamin A. This ratio was later revised to 6:1 and recent research suggests an even higher ratio.1 This means that you have to eat an awful lot of vegetables and fruits to obtain even the daily minimal requirements of vitamin A, assuming optimal conversion.

But the transformation of carotene to retinol is rarely optimal. Diabetics and those with poor thyroid function, a group that includes at least half the adult US population, cannot make the conversion. Children make the conversion very poorly and infants not at all —they must obtain their precious stores of vitamin A from animal fats —yet the low-fat diet is often recommended for children.2 Strenuous physical exercise, excessive consumption of alcohol, excessive consumption of iron (especially from “fortified” white flour and breakfast cereal), use of a number of popular drugs, excessive consumption of polyunsaturated fatty acids, zinc deficiency and even cold weather can hinder the conversion of carotenes to vitamin A3, as does the low-fat diet.

Carotenes are converted by the action of bile salts, and very little bile reaches the intestine when a meal is low in fat. The epicure who puts butter on his vegetables and adds cream to his vegetable soup is wiser than he knows. Butterfat stimulates the secretion of bile needed to convert carotenes from vegetables into vitamin A and at the same time, supplies very easily absorbed true vitamin A. Polyunsaturated oils also stimulate the secretion of bile salts but can cause rapid destruction of carotene unless antioxidants are present.

It is very unwise, therefore, to depend on plant sources for vitamin A. This vital nutrient is needed for the growth and repair of body tissues; it helps protect mucous membranes of the mouth, nose, throat and lungs; it prompts the secretion of gastric juices necessary for proper digestion of protein; it helps to build strong bones and teeth and rich blood; it is essential for good eyesight; it aids in the production of RNA; and contributes to the health of the immune system. Vitamin A deficiency in pregnant mothers results in offspring with eye defects, displaced kidneys, harelip, cleft palate and abnormalities of the heart and larger blood vessels.

Nutrition pioneer Weston Price considered the fat soluble vitamins, especially vitamin A, to be the catalysts on which all other biological processes depend. Efficient mineral uptake and utilization of water-soluble vitamins require sufficient vitamin A in the diet. His research demonstrated that generous amounts of vitamin A insure healthy reproduction and offspring with attractive wide faces, straight teeth and strong sturdy bodies. He discovered that healthy primitives especially value vitamin-A-rich foods for growing children and pregnant mothers. Working in the 1930’s, he found that their diets contained ten times more vitamin A than the typical American diet of the time. This disparity is almost certainly greater today as Americans have forsworn butter and cod liver oil for foods based on polyunsaturated oils.

In third world communities that have come into contact with the West, vitamin A deficiencies are widespread and contribute to high infant mortality, blindness, stunting, bone deformities and susceptibility to infection.4 These occur even in communities that have access to plentiful carotenes in vegetables and fruits. Scarcity of good quality dairy products, a rejection of organ meats as old fashioned or unhealthful, and a substitution of vegetable oil for animal fat in cooking all contribute to the physical degeneration and suffering of third world peoples.

Supplies of vitamin A are so vital to human health that we are able to store large quantities of it in the liver and other organs. Thus it is possible to subsist on a diet low in animal fatfor a considerable period of time before overt symptoms of deficiency appear. But during times of stress, vitamin A stores are rapidly depleted. Strenuous physical exercise, periods of physical growth, pregnancy, lactation and infection are stresses that quickly deplete vitamin A stores. Children with measles rapidly use up vitamin A, often resulting in irreversible blindness. An interval of three years between pregnancies allows mothers to rebuild vitamin A stores so that subsequent children will not suffer diminished vitality.

One aspect of vitamin A that deserves more emphasis is its role in protein utilization. Kwashiorkor is as much a disease of vitamin A deficiency, leading to impaired protein absorption, as it is a result of absence of protein in the diet. High protein, lowfat diets in children induce rapid growth along with depletion of vitamin A supplies. The results —tall, myopic, lanky individuals with crowded teeth, and poor bone structure —are a fixture in America. Growing children actually benefit from a diet that contains more calories as fat than as protein.5 Such a diet, rich in vitamin A, will result in steady, even growth, a sturdy physique and high immunity to disease.

So it’s a bit embarrassing to the low-fat people, especially as the truth is beginning to come out, even in orthodox publications. A recent New York Times article noted that vitamin-A-rich foods like liver, egg yolk, cream and shellfish confer resistance to infectious diseases in children and prevent cancer in adults.6 A Washington Post article hailed vitamin A as “cheap and effective, with wonders still being (re)discovered,” noting that recent studies have found that vitamin A supplements help prevent infant mortality in third world counties, protect measles victims from severe complications and prevent mother-to-child transmission of HIV virus.7 The article lists butter, egg yolk and liver as important sources of vitamin A but claims, unfortunately, that carotenes from vegetables are “equally important.” So vagueness about vitamin A continues, even among science writers.

Those familiar with the work of nutrition pioneer Weston Price are not so easily fooled. They know that vitamin-A-rich foods like liver, eggs, and cod liver oil are vital to good health. If you–or your children–don’t like liver, eggs and cod liver oil, don’t despair. Studies show that the best and most easily absorbed source of vitamin A is butterfat,8 a food relished by young and old alike. So use plenty of butter and cream from pasture-fed cows for good taste and wise nutritional practice.

Why are vitamin A and D from natural sources so important to good health?

There is so much information about this or that vitamin–but Dr. Weston A. Price’s pivotal research on the diets of healthy populations worldwide determined the critical importance of foods that contain ample vitamin A and D. He found that while the 14 healthy cultures that he studied had different diets, one common element were foods rich in these two nutrients. These cultures consumed more than 10 times the amount of vitamin A and D than people in the US–in 1930! And this level would be much higher today. Foods that are particularly dense in these nutrients are high quality fermented cod liver oil (see, egg yolks, liver and butter (from grass-fed animals) and fish eggs.

Dr. Price found that without adequate amounts of these two nutrients that a person could not absorb the other nutrients in the diet no matter how good the diet. In fact, he found that deficiencies in these vitamins caused noticeable genetic changes in the skeletal structure–a narrowing of the skull and face causing crooked and crowded teeth. We are seeing this narrowing in almost every child born today.

Vitamin A and D are the only vitamins that function as hormones. They help express the correct genetic material in the cells. When there is a deficiency, genetic changes can occur.

The best way to insure that your diet is rich in these fat-soluble vitamins is to eat traditional, nutrient-dense foods–foods from animals eating their natural diet.
