Nutrition to grow a healthy baby

Kim with Matthew Born July 2004

• If you are taking a prenatal vitamin, be sure that it is food based. New Chapter is one of our favorite brands.
• We strongly suggest that you take probiotics during pregnancy and breastfeeding (throughout life ideally). Our preferred brand is Jarrow Pearls.
• Eliminate fast food, fried foods, and other unnecessary fats
• Cook with Coconut oil or olive oil- NO vegetable oils or canola oils
• Salt food to taste- Himilayan, Celtic, or Mediterranean salt is best (no standard table salt)
• Consume lots of protein! 75-90 grams per day, taken in several snacks and light meals. Eggs are great, cottage cheese, lean red meats, chicken, hard cheeses, milk, ice cream, yogurt, legumes, beans, etc. You may also consider adding whey protein powder to smoothies or other foods that you enjoy if your protein is truly lacking.
• Go for greens!-leafy lettuces, spinach, vegatables, salads, avacado, green beans, broccoli, asparagus, peas, apples (red and green), and squash are all excellent choices.
• Wipe out Whites- avoid refined sugars, white flour products, white rice, white potatoes (red are fine), and white baked goods. If you are baking, use maple sugar or maple syrup.
• Opt for Oranges- Squash, yams and sweet potatoes, cantaloupe, oranges, peaches, apricots, and other fruits (dried friuts make a great snack).
• Drink LOTS of water! Especially before doctor's appointments near term!
• Delve into fruits and berries- strawberries and blueberries (especially good), honeydew melons, watermelon, kiwi, tangerines, pineapple, cherries, apples, bananas, and pears all make great snacks!
• Increase intake of Omega 3Taking one tablespoon of cod liver oil daily can be fabulous for health, not just in pregnancy, but always. Fish is one of the most beneficial proteins that you can consume, but it can be very toxic these days- Alaskan salmon is one of the safest you can eat. Watch for mercury levels in fish and also you should know if farm-raised fish are being fed suitable diets (most are not). Avoid all raw fish and oysters.
• Reach for roughage- Consuming enough fiber can keep your bowels regular and fend off hemorrhoids. Most fruits and veggies will supply fiber- asparagus, broccoli, cabbage, apples, canned beans,--also helps to keep blood sugar levels stable and to lowel bad cholesterol.
• When drinking liquids other than water, avoid carbonated drinks that leach calcium from bones and NEVER drink diet drinks, caffeine or alchohol. Juice is OK on occassion, but should not be from concentrate. Milk drinkers, should limit intake to 8-12 ounces daily. Calcium is richest in green leafy vegetables.
• This list of produce is most susceptible to pesticides and other toxins, so buy organic for these whenever possible to prevent these chemicals from being passed to your baby:
  • leafy vegetables (lettuce, celery, green onions)
  • spinach
  • culinary herbs
  • peas and beans
  • peppers
  • summer squash, eggplant or cucumbers
  • winter squash and pumpkins
  • bulb vegetables
  • root vegetables
  • carrots
  • melons
  • vine-ripe tomatoes
  • strawberries
  • apples
  • pears
  • citrus fruits
  • kiwi fruit
• If you are experiencing high blood pressure, swelling, or anything else that is out of the ordinary during pregnancy, or if you are vegan, contact us immediately for a list of additional nutritional considerations.

• Tetracycline (a commonly prescribed antibiotic, may retard bone growth and affect tooth development) and all other antiobiotics
• Over-the-counter medications including, but not limited to: decongestants, cough medicines, sleep medications, headache remedies, and asipirin
• paint fumes
• rug shampoos
• lawn chemicals
• cleaning solvents
• pesticides
• x-rays
• caffeine
• white potatoes (red potatoes are fine)
• diet drinks or any product containing aspartame (NutraSweet)- can cause severe birth defects and is very bad for any adult's health
• shell fish and other fish that may contain dangerous levels of mercury(i.e. swordfish)- also note that farm-raised fish is not always considered safe due to poor feed being used
• cat litter and garden soil, as Mom can contract Toxoplasmosis which can lead to sever birth defects if contracted during pregnancy
• cigarette smoke (including second hand)
• ALL alcohol and illegal drugs

Dietary Guidelines

1. Eat whole, unprocessed foods.
2. Eat beef, lamb, game, organ meats, poultry and eggs from pasture-fed animals.
3. Eat wild fish (not farm-raised) and shellfish from unpolluted waters.
4. Eat full-fat milk products from pasture-fed cows, preferably raw and/or fermented, such as raw milk, whole yogurt, kefir, cultured butter, whole raw cheeses and fresh and sour cream. (Imported cheeses that say "milk" or "fresh milk" on the label are raw.)
5. Use animal fats, especially butter, liberally.
6. Use traditional vegetable oils only--extra virgin olive oil, expeller-expressed sesame oil, small amounts of expeller-expressed flax oil, and the tropical oils--coconut oil, palm oil and palm kernel oil.
7. Take cod liver oil regularly to provide at least 10,000 IU vitamin A and 1,000 IU vitamin D per day.
8. Eat fresh fruits and vegetables--preferably organic--in salads and soups, or lightly steamed with butter.
9. Use whole grains, legumes and nuts that have been prepared by soaking, sprouting or sour leavening to neutralize phytic acid, enzyme inhibitors and other anti-nutrients.
10. Include enzyme-enhanced lacto-fermented vegetables, fruits, beverages and condiments in your diet on a regular basis.
11. Prepare homemade meat stocks from the bones of chicken, beef, lamb and fish and use liberally in soups, stews, gravies and sauces.
12. Use filtered water for cooking and drinking.
13. Use unrefined salt and a variety of herbs and spices for food interest and appetite stimulation.
14. Make your own salad dressing using raw vinegar, extra virgin olive oil and a small amount of expeller-expressed flax oil.
15. Use natural sweeteners in moderation, such as raw honey, maple syrup, maple sugar, date sugar, dehydrated cane sugar juice (sold as Rapadura) and stevia powder.
16. Use only unpasteurized wine or beer in strict moderation with meals.
17. Cook only in stainless steel, cast iron, glass or good quality enamel.
18. Use only natural, food-based supplements.
19. Get plenty of sleep, exercise and natural light.
20. Think positive thoughts and practice forgiveness.

Dietary Dangers

1. Do not eat commercially processed foods such as cookies, cakes, crackers, TV dinners, soft drinks, packaged sauce mixes, etc. Read labels!
2. Avoid all refined sweeteners such as sugar, dextrose, glucose, high fructose corn syrup and fruit juices.
3. Avoid white flour, white flour products and white rice.
4. Avoid all hydrogenated or partially hydrogenated fats and oils.
5. Avoid all refined liquid vegetable oils made from soy, corn, safflower, canola or cottonseed.
6. Do not use polyunsaturated oils for cooking, sautéing or baking.
7. Avoid foods fried in polyunsaturated oils or partially hydrogenated vegetable oils.
8. Do not practice veganism. Animal products provide vital nutrients not found in plant foods.
9. Avoid products containing protein powders as they usually contain carcinogens formed during processing; and consumption of protein without the cofactors occurring in nature can lead to deficiencies, especially of vitamin A.
10. Avoid processed, pasteurized milk; do not consume ultrapasteurized milk products, lowfat milk, skim milk, powdered milk or imitation milk products.
11. Avoid factory-farmed eggs, meats and fish.
12. Avoid highly processed luncheon meats and sausage.
13. Avoid rancid and improperly prepared seeds, nuts and grains found in granolas, quick rise breads and extruded breakfast cereals, as they block mineral absorption and cause intestinal distress.
14. Avoid canned, sprayed, waxed and irradiated fruits and vegetables. Avoid genetically modified foods (found in most soy, canola and corn products).
15. Avoid artificial food additives, especially MSG, hydrolyzed vegetable protein and aspartame, which are neurotoxins. Most soups, sauce and broth mixes and most commercial condiments contain MSG, even if not indicated on the label.
16. Individuals sensitive to caffeine and related substances should avoid coffee, tea and chocolate.
17. Avoid aluminum-containing foods such as commercial salt, baking powder and antacids. Do not use aluminum cookware or deodorants containing aluminum.
18. Do not drink fluoridated water.
19. Avoid synthetic vitamins and foods containing them.
20. Avoid distilled liquors.
21. Do not use a microwave oven.

Confused About Fats?

The following nutrient-rich traditional fats have nourished healthy population groups for thousands of years:

For Cooking

• Butter
• Tallow and suet from beef and lamb
• Lard from pigs
• Chicken, goose and duck fat
• Coconut, palm and palm kernel oils

For Salads

• Extra virgin olive oil (also OK for cooking)
• Expeller-expressed sesame and peanut oils
• Expeller-expressed flax oil (in small amounts)

For Fat-Soluble Vitamins

• Fish liver oils such as cod liver oil (preferable to fish oils, which do not provide fat-soluble vitamins, can cause an overdose of unsaturated fatty acids and usually come from farmed fish.)

The following newfangled fats can cause cancer, heart disease, immune system dysfunction, sterility, learning disabilities, growth problems and osteoporosis:

• All hydrogenated and partially hydrogenated oils
• Industrially processed liquid oils such as soy, corn, safflower, cottonseed and canola
• Fats and oils (especially vegetable oils) heated to very high temperatures in processing and frying.

The Many Roles of Saturated Fat

Saturated fats, such as butter, meat fats, coconut oil and palm oil, tend to be solid at room temperature. According to conventional nutritional dogma, these traditional fats are to blame for most of our modern diseases--heart disease, cancer, obesity, diabetes, malfunction of cell membranes and even nervous disorders like multiple sclerosis. However, many scientific studies indicate that it is processed liquid vegetable oil--which is laden with free radicals formed during processing--and artificially hardened vegetable oil--called trans fat--that are the culprits in these modern conditions, not natural saturated fats.

Humans need saturated fats because we are warm blooded. Our bodies do not function at room temperature, but at a tropical temperature. Saturated fats provide the appropriate stiffness and structure to our cell membranes and tissues. When we consume a lot of liquid unsaturated oils, our cell membranes do not have structural integrity to function properly, they become too "floppy," and when we consume a lot of trans fat, which is not as soft as saturated fats at body temperature, our cell membranes become too "stiff."

Contrary to the accepted view, which is not scientifically based, saturated fats do not clog arteries or cause heart disease. In fact, the preferred food for the heart is saturated fat; and saturated fats lower a substance called Lp(a), which is a very accurate marker for proneness to heart disease.

Saturated fats play many important roles in the body chemistry. They strengthen the immune system and are involved in inter-cellular communication, which means they protect us against cancer. They help the receptors on our cell membranes work properly, including receptors for insulin, thereby protecting us against diabetes. The lungs cannot function without saturated fats, which is why children given butter and full-fat milk have much less asthma than children given reduced-fat milk and margarine. Saturated fats are also involved in kidney function and hormone production.

Saturated fats are required for the nervous system to function properly, and over half the fat in the brain is saturated. Saturated fats also help suppress inflammation. Finally, saturated animal fats carry the vital fat-soluble vitamins A, D and K2, which we we need in large amounts to be healthy.

Human beings have been consuming saturated fats from animals products, milk products and the tropical oils for thousands of years; it is the advent of modern processed vegetable oil that is associated with the epidemic of modern degenerative disease, not the consumption of saturated fats.

The Fat-Soluble Activators

The crux of Dr. Price's research has to do with what he called the "fat-soluble activators," vitamins found in the fats and organ meats of grass-fed animals and in certain seafoods, such as fish eggs, shellfish, oily fish and fish liver oil. The three fat-soluble activators are vitamin A, vitamin D and a nutrient he referred to as Activator X, now considered to be vitamin K2, the animal form of vitamin K. In traditional diets, levels of these key nutrients were about ten times higher than levels in diets based on the foods of modern commerce, containing sugar, white flour and vegetable oil. Dr. Price referred to these vitamins as activators because they serve as the catalysts for mineral absorption. Without them, minerals cannot by used by the body, no matter how plentiful they may be in the diet.

Modern research completely validates the findings of Dr. Price. We now know that vitamin A is vital for mineral and protein metabolism, the prevention of birth defects, the optimum development of infants and children, protection against infection, the production of stress and sex hormones, thyroid function, and healthy eyes, skin and bones. Vitamin A is depleted by stress, infection, fever, heavy exercise, exposure to pesticides and industrial chemicals, and excess protein consumption (hence our warnings against the consumption of excess protein in the form of lean meat, lowfat milk and protein powders.)

Modern research has also revealed the many roles played by vitamin D, which is needed for mineral metabolism, healthy bones and nervous system, muscle tone, reproductive health, insulin production, protection against depression, and protection against chronic diseases like cancer and heart disease.

Vitamin K plays an important role in growth and facial development, normal reproduction, development of healthy bones and teeth, protection against calcification and inflammation of the arteries, myelin synthesis and learning capacity.

Modern health literature is rife with misinformation about the fat-soluble vitamins. Many health writers claim that humans can obtain adequate vitamin A from plant foods. But the carotenes in plant foods are not true vitamin A. Instead, they serve as precursors that are converted into vitamin A in the small intestine. Human beings are not good converters of vitamin A, especially as infants or whenthey suffer from diabetes, thyroid problems or intestinal disorders. Thus, for optimal health, humans require animal foods containing liberal amounts of vitamin A. Similarly, many claim that adequate vitamin D can be obtained from a short daily exposure to sunlight. But the body only makes vitamin D when the sun is directly overhead, that is, in the summer months, during midday. For most of the year (and even in the summer for those who do not make a practice of sunbathing), humans must obtain vitamin D from foods. As for vitamin K, most health books mention only its role in blood clotting, without recognizing the many other vital roles played by this nutrient.

Vitamins A, D and K work synergistically. Vitamins A and D tell cells to make certain proteins; after the cellular enzymes make these proteins, they are activated by vitamin K. This synergy explains reports of toxicity from taking vitamins A, D or K in isolation. All three of these nutrients must come together in the diet or the body will develop deficiencies in the missing activators.

The vital roles of these fat-soluble vitamins and the high levels found in the diets of healthy traditional peoples confirm the importance of pasture-feeding livestock. If domestic animals are not consuming green grass, vitamins A and K will be largely missing from their fat, organ meats, butterfat and egg yolks; if the animals are not raised in the sunlight, vitamin D will be largely missing from these foods.

Because it is so difficult to obtain adequate fat-soluble activators in the modern diet, Dr. Price recommended cod liver oil to provide vitamins A and D, along with a source of vitamin K, such as butter from grass-fed animals or what he called high-vitamin butter oil, made by low-temperature centrifuging of butter from cows eating rapidly growing grass. Consumed in liberal amounts during pregnancy, lactation and the period of growth, these nutrients ensure the optimal physical and mental development of children; consumed by adults, these nutrients protect against acute and chronic disease.

It is important to choose cod liver oil with care as many brands contain very little vitamin D, with potential toxicity of vitamin A. For recommended brands see westonaprice.org/basicnutrition/cod-liver-oil-menu.html.

What's Wrong With "Politically Correct" Nutrition?

"Avoid saturated fats."
Saturated fats play many important roles in the body. They provide integrity to the cell wall, promote the body's use of essential fatty acids, enhance the immune system, protect the liver and contribute to strong bones. The lungs and the kidneys cannot work without saturated fat. Saturated fats do not cause heart disease. In fact, saturated fats are the preferred food for the heart. Because your body needs saturated fats, it makes them out of carbohydrates and excess protein when there are not enough in the diet.

"Limit cholesterol."
Dietary cholesterol contributes to the strength of the intestinal wall and helps babies and children develop a healthy brain and nervous system. Foods that contain cholesterol also provide many other important nutrients. Only oxidized cholesterol, found in most powdered milk and powdered eggs, contributes to heart disease. Powdered milk is added to 1% and 2% milk.

"Use more polyunsaturated oils."
Polyunsaturates in more than small amounts contribute to cancer, heart disease, autoimmune diseases, learning disabilities, intestinal problems and premature aging. Large amounts of polyunsaturated fats are new to the human diet, due to the modern use of commercial liquid vegetable oils. Even olive oil, a monounsaturated fat considered to be healthy, can cause imbalances at the cellular level if consumed in large amounts.

"Avoid red meat."
Red meat is a rich source of nutrients that protect the heart and nervous system; these include vitamins B12 and B6, zinc, phosphorus, carnitine and coenzyme-Q10.

"Cut back on eggs."
Eggs are nature's perfect food, providing excellent protein, the gamut of vitamins and important fatty acids that contribute to the health of the brain and nervous system. Americans had less heart disease when they ate more eggs. Egg substitutes cause rapid death in test animals.

"Restrict salt."
Salt is crucial to digestion and assimilation. Salt is also necessary for the development and function of the nervous system. Table salt in it's common form is basically poison. Select only a high quality sea salt. IT's role is especially essential in pregnancy.

"Eat lean meat and drink lowfat milk."
Lean meat and lowfat milk lack fat-soluble vitamins needed to assimilate the protein and minerals in meat and milk. Consumption of lowfat foods can lead to depletion of vitamin A and D reserves.

"Limit fat consumption to 30 percent of calories."
Thirty percent calories as fat is too low for most people, leading to low blood sugar and fatigue. Traditional diets contained 30 percent to 80 percent of calories as healthy fats, mostly of animal origin.

"Eat 6-11 servings of grains per day."
Most grain products are made from white flour, which is devoid of nutrients. Additives in white flour can cause vitamin deficiencies. Whole grain products can cause mineral deficiencies and intestinal problems unless properly prepared.

"Eat at least 5 servings of fruits and vegetables per day."
Fruits and vegetables receive an average of 10 applications of pesticides, from seed to storage. Consumers should seek out organic produce. Quality counts!

"Eat more soy foods."
Modern soy foods block mineral absorption, inhibit protein digestion, depress thyroid function and contain potent carcinogens.

Myths and Truths About Nutrition

Myth: Heart disease in America is caused by consumption of cholesterol and saturated fat from animal products.
Truth: During the period of rapid increase in heart disease (1920-1960), American consumption of animal fats declined but consumption of hydrogenated and industrially processed vegetable fats increased dramatically (USDA-HNIS).

Myth: Saturated fat clogs arteries.
Truth: The fatty acids found in artery clogs are mostly unsaturated (74%) of which 41% are polyunsaturated (Lancet 1994 344:1195).

Myth: Vegetarians live longer.
Truth: The annual all-cause death rate of vegetarian men is slightly more than that of non-vegetarian men (.93% vs .89%); the annual all-cause death rate of vegetarian women is significantly more than that of non-vegetarian women (.86% vs .54%) (Wise Traditions 2000 1:4:16-17).

Myth: Vitamin B12 can be obtained from certain plant sources such as blue-green algae and fermented soy products.
Truth: Vitamin B12 is not absorbed from plant sources. Modern soy products actually increase the body's need for B12 (Soybeans: Chemistry & Technology
Vol 1 1972).

Myth: For good health, serum cholesterol should be less than 180 mg/dl.
Truth: The all-cause death rate is higher in individuals with cholesterol levels lower than 180 mg/dl (Circulation 1992 86:3).

Myth: Animal fats cause cancer and heart disease.
Truth: Animal fats contain many nutrients that protect against cancer and heart disease; elevated rates of cancer and heart disease are associated with consumption of large amounts of vegetable oil (Federation Proceedings July 1978 37:2215).

Myth: Children benefit from a lowfat diet.
Truth: Children on lowfat diets suffer from growth problems, failure to thrive and learning disabilities (Food Chemistry News 10/3/94).

Myth: A lowfat diet will make you "feel better...and increase your joy of living."
Truth: Lowfat diets are associated with increased rates of depression, psychological problems, fatigue, violence and suicide (Lancet 3/21/92 Vol 339).

Myth: To avoid heart disease, we should use margarine instead of butter.
Truth: Margarine eaters have twice the rate of heart disease as butter eaters (Nutrition Week 3/22/91 21:12).

Myth: Americans do not consume enough essential fatty acids (EFAs).
Truth: Americans consume far too much of one kind of EFA (omega-6 EFAs found in most polyunsaturated vegetable oils) but not enough of another kind of EFA (omega-3 EFAs found in fish, fish oils, eggs from pasture-fed chickens, dark green vegetables and herbs, and oils from certain seeds such as flax and chia, nuts such as walnuts and in small amounts in all whole grains) (American Journal of Clinical Nutrition 1991 54:438-63).

Myth: The "cave man diet" was low in fat.
Truth: Throughout the world, primitive peoples sought out and consumed fat from fish and shellfish, water fowl, sea mammals, land birds, insects, reptiles, rodents, bears, dogs, pigs, cattle, sheep, goats, game, eggs, nuts and milk products (Abrams, Food & Evolution 1987).

Myth: A vegetarian diet will protect you against atherosclerosis.
Truth: The International Atherosclerosis Project found that vegetarians had just as much atherosclerosis as meat eaters (Laboratory Investigations 1968 18:498).

Myth: Lowfat diets prevent breast cancer.
Truth: A recent study found that women on very lowfat diets (less than 20%) had the same rate of breast cancer as women who consumed large amounts of fat (New England Journal of Medicine 2/8/96).

Myth: Coconut oil causes heart disease.
Truth: When coconut oil was fed as 7% of energy to patients recovering from heart attacks, the patients had greater improvement compared to untreated controls, and no difference compared to patients treated with corn or safflower oils. Populations that consume coconut oil have low rates of heart disease. Coconut oil may also be one of the most useful oils to prevent heart disease because of its antiviral and antimicrobial characteristics (Journal of the American Medical Association 1967 202:1119-1123; American Journal of Clinical Nutrition 1981 34:1552).

Myth: Saturated fats inhibit production of anti-inflammatory prostaglandins.
Truth: Saturated fats actually improve the production of all prostaglandins by facilitating the conversion of essential fatty acids ("Tripping Lightly Down the Prostaglindin Pathways," westonaprice.org).

Myth: Arachidonic acid in foods like liver, butter and egg yolks causes production of "bad" inflammatory prostaglandins.
Truth: Series 2 prostaglandins that the body makes from arachidonic acid both encourage and inhibit inflammation under appropriate circumstances. Arachidonic acid is vital for the function of the brain and nervous system (Ibid).

Myth: Beef causes colon cancer
Truth: Argentina, with higher beef consumption, has lower rates of colon cancer than the US. Mormons have lower rates of colon cancer than vegetarian Seventh Day Adventists (Cancer Research 1975 35:3513).

Myths and Truths About Soy

Myth: Use of soy as a food dates back many thousands of years.
Truth: Soy was first used as a food during the late Chou dynasty (1134-246 BC) only after the Chinese learned to ferment soy beans to make foods like tempeh, natto and tamari.

Myth: Asians consume large amounts of soy foods.
Truth: Average consumption of soy foods in China is 10 grams (about 2 teaspoons) per day and up to 60 grams in parts of Japan. Asians consume soy foods in small amounts as a condiment, and not as a replacement for animal foods.

Myth: Modern soy foods confer the same health benefits as traditionally fermented soy foods.
Truth: Most modern soy foods are not fermented to neutralize toxins in soybeans, and are processed in a way that denatures proteins and increases levels of carcinogens.

Myth: Soy foods provide complete protein.
Truth: Like all legumes, soybeans are deficient in sulfur-containing amino acids methionine and cystine. In addition, modern processing denatures fragile lysine.

Myth: Fermented soy foods can provide vitamin B12 in vegetarian diets.
Truth: The compound that resembles vitamin B12 in soy cannot be used by the human body; in fact, soy foods cause the body to require more B12.

Myth: Soy formula is safe for infants.
Truth: Soy foods contain trypsin inhibitors that inhibit protein digestion and affect pancreatic function. In test animals, diets high in trypsin inhibitors led to stunted growth and pancreatic disorders. Soy foods increase the body's requirement for vitamin D, needed for strong bones and normal growth. Phytic acid in soy foods results in reduced bioavailabilty of iron and zinc which are required for the health and development of the brain and nervous system. Soy also lacks cholesterol, likewise essential for the development of the brain and nervous system. Megadoses of phytoestrogens in soy formula have been implicated in the current trend toward increasingly premature sexual development in girls and delayed or retarded sexual development in boys.

Myth: Soy foods can prevent osteoporosis.
Truth: Soy foods can cause deficiencies in calcium and vitamin D, both needed for healthy bones. Calcium from bone broths and vitamin D from seafood, lard and organ meats prevent osteoporosis in Asian countries--not soy foods.

Myth: Modern soy foods protect against many types of cancer.
Truth: A British government report concluded that there is little evidence that soy foods protect against breast cancer or any other forms of cancer. In fact, soy foods may result in an increased risk of cancer.

Myth: Soy foods protect against heart disease.
Truth: In some people, consumption of soy foods will lower cholesterol, but there is no evidence that lowering cholesterol lowers one's risk of developing heart disease.

Myth: Soy estrogens (isoflavones) are good for you.
Truth: Soy isoflavones are phyto-endocrine disrupters. At dietary levels, they can prevent ovulation and stimulate the growth of cancer cells. Eating as little as 30 mg isoflavones (from about 30 g soy protein) per day can result in hypothyroidism with symptoms of lethargy, constipation, weight gain and fatigue.

Myth: Soy foods are safe and beneficial for women to use in their postmenopausal years.
Truth: Soy foods can stimulate the growth of estrogen-dependent tumors and cause thyroid problems. Low thyroid function is associated with difficulties in menopause.

Myth: Phytoestrogens in soy foods can enhance mental ability.
Truth: A recent study found that women with the highest levels of estrogen in their blood had the lowest levels of cognitive function; in Japanese Americans, tofu consumption in mid-life is associated with the occurrence of Alzheimer's disease in later life.

Myth: Soy isoflavones and soy protein isolate have GRAS (Generally Recognized as Safe) status.
Truth: Archer Daniels Midland (ADM) recently withdrew its application to the FDA for GRAS status for soy isoflavones following an outpouring of protest from the scientific community. The FDA never approved GRAS status for soy protein isolate because of concern regarding the presence of toxins and carcinogens in processed soy.

Myth: Soy foods are good for your sex life.
Truth: Numerous animal studies show that soy foods cause infertility in animals. Soy consumption lowers testosterone levels in men. Tofu was consumed by Buddhist monks to reduce libido.

Myth: Soybeans are good for the environment.
Truth: Most soybeans grown throughout the world are genetically engineered to allow farmers to use large amounts of herbicides, creating toxic runoff.

Myth: Soybeans are good for developing nations.
Truth: In third world countries, soybeans replace traditional crops and transfer the value-added of processing from the local population to multinational corporations.
