Vitamin A - The Grass Vitamin


Vitamin A – “Grass Vitamin”


Dr. Weston Price confirmed the value of vitamin A in traditional diets of primitive peoples during his studies in the 1930s and 40s

Functions of Vitamin A  (Retinol) in the Body


      Sufficient vitamin A needed for mineral uptake / utilization of water-soluble vitamins;


      Essential for good eyesight (retinal component) - Vitamin A is called “retinol” because of its presence in the retina;


      Builds muscle


      Utilizes protein – initiates gastric juice secretion; (High-protein diet depletes vitamin A - e.g. heavy meat-eating);


      “Beauty” Vitamin - keeps the skin smooth and soft


      Improves growth in nutrient-deprived children


      Powerful inhibitor of prostate cancer


      Antioxidant controls free radicals in body fats, and its presence in Cod liver oil protects against lipid peroxide damage;


      Growth/repair of body tissues - used in cell division;


      Helps build strong bones/teeth, rich blood


      Protects mucous membranes of mouth / nose / throat / lungs / entire digestive tract / bladder / kidneys


      Immune system builder


      Vitamin A protects against possible dioxins and pesticides - a useful ingredient in cod liver oil;


      Reproduction - necessary for sperm production. Used in cell division and differentiation (i.e. cell decides what it will be), and prenatal development (Aids RNA production); Prevents spontaneous abortion;


      Sex Hormone Production – needed for conversion of cholesterol into steroid hormones.



      Vitamin A stores are rapidly DEPLETED by EXERCISE, FEVER and STRESS


      Goose bumps on skin (mostly at back of upper arm);


      Night blindness;


      Keratomalacia (severe nutritional deficiency, corneal ulceration, extreme eye dryness);


      Increased rate of infection


      Increase in mortality


      Advanced deficiency affects mucous membranes of respiratory/gastro-intestinal/genito-urinary tracts


      Deficiency in pregnancy causes malformations in baby – eye-defects, displaced kidneys, harelip, cleft palate, heart abnormalities, larger blood vessels. 




Vitamin A, Where are you?

 - This important vitamin is disappearing from today’s mainstream diet


We can Obtain Vitamin A from the Fat of Animals, Birds and Fish


      But… only in significant amounts if their diet includes vitamin A or carotenes - as found in diets of green pasture, insects, fish meal and plankton. Retinol (converted by the body to retinal, retinoic acid, + others) is the most usable form of vitamin A and is found in the following sources of animal, bird or fish fat:


         Oily fish

         Liver and other organ meat (e.g. kidney)

         Whole milk and products (e.g. butterfat, cream, cheese) from grass-fed animals - Low fat milk has synthetic vitamin A added (because it doesn’t contain much fat).

         Egg yolks and chicken (from pastured hens, i.e. grass-fed, insect-eating hens)

         Shellfish (not recommended because of their possible toxicity).


      And… Current Mass Farming Methods Mostly Eliminate Vitamin A from the Livestock Diet

The current farming practice of keeping livestock in confinement results in an absence of vitamin A in their fat.  If present however, the fat-soluble vitamins (A, D, E and K) are relatively stable and essentially will survive the pasteurization process.  




(Confined Animal Farming Operations)


      80% of the 35 million beef cattle slaughtered annually in the U.S. are in the hands of four huge corporations

Most beef cattle spend the last few months of their lives at feedlots, crowded into dusty, manure-laden holding pens, breathing in air rife with bacteria.

Feedlot cattle are routinely implanted with growth-promoting hormones, given antibiotics, and fed unnaturally rich (typically herbicide/pesticide-containing corn and soybean) diets to make them gain weight faster. 

The unnatural existence of a CAFO dairy cow, milked 10 months out of 12, lasts an average of 3½ years, compared to 12-15 years for a pastured cow.


Cattle, with their multi-chambered stomachs, are designed

to “chew the cud”, and eat a grass-based, high fiber diet


      Compared with grass-fed cattle beef and milk products, CAFO raised animal products have:


-       More total fat, saturated fat, cholesterol and calories


-       Less beta-carotene, vitamins A, E, C, and Omega-3 fatty acids (Fresh forage has 10-12 times more Omega-3 ALA than cereal grains)


-       Less conjugated linoleic acid (CLA) - French researchers compared CLA levels in the breast tissues of 360 women to find that the women with the most CLA had a 74% lower risk of breast cancer than the women with the least CLA

Bougnoux et al, Inform, 10:S43, 1999    


Beef from grass-fed cattle contains about twice

the amount of beta-carotene as grain-fed beef.


      Pasture-raised cows produce only a third of the milk of CAFO animals - and so their milk is more nutrient dense because it has not been “watered down” by greater production quantities (The cow has eaten only so many nutrients to transfer to her milk). The butter made using milk from a cow fed on 100% pasture will be bright yellow and taste delicious! The creamiest milk comes from pastured Jersey or Guernsey cows.


      Hope for the future - In the last few years, the number of U.S. farms raising pure pasture-fed beef has increased from 50 to >1,000 and climbing, but still represents only about 1% of the nation’s supply.


      And anyway… processors prefer to utilize vegetable oils (containing  ß-carotene), instead of animal fats 



We can Obtain Vitamin A by converting dietary carotenes


      But… optimal conversion NEEDS FAT and is influenced by other factors - We are taught that we may obtain vitamin A by eating and converting provitamin A carotenes (such as ß-carotene) in brightly colored fruits and vegetables. The problem is that this conversion only takes place when fat is present, and then inefficiently without optimal conversion conditions. (An estimate of the absorption rate for carotene is 20%-50% of that of retinol, which itself is estimated at 70%-90% Olson JA. Carotenes are converted in the upper intestines by the action of bile, which reaches this area only when its production is stimulated by fat in the meal. Here lies the wisdom of putting butter on your vegetables and adding cream to the soup!


-       Other concurrent dietary factors influencing carotenoid bioavailability and absorption - include the amount of dietary carotenes, interactions with other carotenes, presence of dietary fiber, nutritional deficiencies of zinc and/or protein, and disease states.

 Erdman J. The physiologic chemistry of carotenes in man.


Absorption efficiency OF β-Carotene is estimated to be between 9–22%. The absorption and conversion of carotenoids may depend on the form that the β-carotene is in (e.g., cooked vs. raw vegetables, or in a supplement), the intake of fats and oils at the same time, and the current stores of vitamin A and β-carotene in the body. WIkipedia


-       Carotenes are found in: dark leafy vegetables, algae, red and yellow vegetables /tubers (E.g. carrots), red and orange fruits/flowers /juices, and is especially high in red palm oil (a common, strong-flavored cooking oil used in W. Africa), and is even up to 10 times higher in buriti palm oil.


      Thoughts on the Edenic diet - Before the Great Flood, people had a vegetarian diet, however, there were certainly shepherds at this time, since Abel, son of Adam and Eve was one. In addition to sacrificing meat, we assume that people used the other sheep products, such as wool, milk and skins (we know God clothed Adam and Eve in animal skins in the garden of Eden).  We surmise that man also availed himself of other animal products, such as cows’ and goats’ milk, butter, cream, cheese. These animal fats would therefore have provided the needed fat catalyst to effect carotene conversion.


      Other carotene tidbits


         Both vitamin A and carotene content are reduced by cooking


         Carotenes do not convert to retinol when the body already contains sufficiently high levels


         FDA regulations currently allow product labels to list carotenes as vitamin  A


         Approximately one third of the retinol in the American diet is derived from provitamin A carotenes



We can Obtain Vitamin A from Fortified Foods


      Dietary vitamin A intake in the U.S. is an estimated 25% ß-carotene and 75% vitamin A (mainly from dairy products and synthetically fortified foods)


      A synthetic vitamin A is usually added to low-fat/skim milk but not usually to whole milk – since vitamin A is naturally present in milk fat, more so from pastured cows, and survives pasteurization


Daily Dosages of Natural vitamin A




Daily Dosages of Vitamin A

 (as Recommended by Weston A. Price Foundation)

Children 3 months - 12 years – 5000 IU

Children over 12 years and adults – 10,000 IU

Pregnant/Nursing Women  20,000 IU

Under stress or treating disease condition – Up to 90,000 IU for several weeks

Example Food Amounts of Vitamin A

3oz. Cooked beef liver – 30,325 IU

3oz. Cooked chicken liver – 13,920 IU

1 tsp. Green Pastures® Cod Liver Oil – 11,500 IU

1 tsp. Radiant Life® Cod Liver Oil – 10,000 IU

2 Tbsp. Heavy Cream – 440 IU

1 Tbsp. Butter – 355 IU

1 Cup Whole milk (3.25% fat) – 249 IU

1 oz. Cheddar cheese – 300 IU

1 large, fried egg – ~335 IU

2 oz. cottage cheese – 184 IU

1 Tbsp. low fat cream cheese – 56 IU

4 oz. low fat yogurt – 58 IU



Vitamins A and D work hand-in-hand with each other

 and must be present in balanced amounts


      It is important to realize that vitamin A and D work hand-in-hand - both protecting and supporting one another. Human studies not taking this into account produce skewed results, and animal studies show that even moderate amounts of vitamin D (from any source) increases the body's need for vitamin A.



Vitamin A Toxicity Reports have been distorted


Various studies seem to support the idea that dietary vitamin A contributes to an increased risk of bone fracture and birth defects, even at low doses.


      These alarming study results did not:


(1)         Take into account the need for concurrent balanced vitamin D intake –The evidence suggests that the negative effects of excess vitamin A are actually the consequence of a vitamin D deficiency. When a basic level of vitamin D is provided to balance adequate vitamin A intake (as found in high-vitamin cod liver oil), as well as other nutrients, we exhibit optimum skeletal health, including improved bone mineral density.


(2)         Differentiate between using natural or synthesized vitamin A - To promote healthy development of her baby, it used to be that a pregnant mother was generally advised to eat a portion of cooked beef liver once a week, which contains ~35,000 IU vitamin A.  And yet, a moderate dose of 10,000 IU or more of a synthetic version, such as water-soluble, solidified, emulsified retinyl palmitate, seems to negatively affect embryonic development.  It should be emphasized that research shows that an appropriate, smaller dose of even synthetic vitamin A supplementation prevents birth defects, blindness and protein deficiency disease (since the body can not utilize dietary protein without vitamin A).


Dr. Weston Price discovered that butterfat from grass-eating animals protects against vitamin A toxicity.
