Choline and Betaine – water soluble nutrients

Choline is a newer discovery in the nutrient world. It is considered to be a member of the water soluble B vitamins group which are nutrients involved in metabolism – the use of energy within the body. We can produce small amounts of choline so it isn’t considered a vitamin but as we can not produce enough for health it is considered an essential nutrient. (1) Betaine is a slightly different form of choline. Choline is found throughout the body but is particularly important within the brain and is needed for the neurotransmitter acetylcholine. Betaine is a metabolite of choline.

Choline, a water soluble nutrient. Foods Sources and symptoms of deficiency.

Choline is most typically found within phospholipids (such as phosphatidylcholine) which are important in membranes and as messenger chemicals within the brain and in the immune system. It may play a role in prenatal brain development but research on supplementation within pregnancy r to protect cognitive skills in the elderly is still in early stages. (1)

Choline is a  methyl donor (1) which means it can share a methyl group – essentially one carbon atom with three hydrogen atoms with an overall neutral charge.

An important role of methyl groups is in the release of energy from sugar within mitochondria. The methyl group is passed back and forth between nutrients and enzymes that are involved in breaking down a molecule of fat or sugar for use of the stored energy that is released when a double bond is broken. The methyl group is combined with an acetyl group when it is removed from the area on the chain of carbon molecules when a double bond is broken. An acetyl group is an atom of carbon combined with one atom of hydrogen and the group has a negative charge. The process for breaking down the glucose sugar molecule is called the Krebs cycle and most beginning level organic chemistry or nutrition students will remember having to memorize all of the steps involved. My summary may be inaccurate – college was a long time ago – the important point is that B vitamins and methyl donors are needed for mitochondria to be able to release energy from glucose/sugar molecules).

  • (The Krebs cycle is also known as the “citric acid cycle or the tricarboxylic acid (TCAcycle.” More info: Krebs cycle.)

Methyl groups are also important in controlling gene activity. They act like an on/off switch for genes. A gene that is fully methylated – all the available double bonds between carbon atoms are broken into single bonds with a methyl group added instead – is in the off position, the protein that the gene would encode is not being made. Genes that are unmethylated have double bonds and are in the on position, the pattern for assembling amino acids into a protein can be read by a matching strand of RNA and the protein can be formed (generally in the endoplasmic reticulum or Golgi apparatus areas of a cell).

Betaine and the more familiar B vitamins folate (B9 if anyone is counting), B6 and B12 are also methyl donors. Folate deficiency has been associated with less gene methylation (a histone is part of a gene). (2) More about methyl donors as a group is available here:  Methyl Donors and BPA.

  • The number system for naming B vitamins was derived at an earlier stage of research and some of the chemicals that were given numbers at the time were discovered to not be essential nutrients – meaning the body was able to form them within the normal health and didn’t essentially need to have them included in the diet (so that is why we don’t hear about a B4, B8, B10 or B11).

Excessive intake of choline above 7500 milligrams may cause a drop in blood pressure, sweating, vomiting and digestive upset, and change in body odor. The recommended Upper Limit is 3,500 mg/day. It would be difficult to reach that amount with food sources. (Safety information, lpi.oregonstate.edu)

Food Sources of Choline:

Good sources of choline include meats, fish & shellfish, eggs/egg yolks, cheese, milk, yogurt, broccoli, cauliflower, cabbage, kale, kohlrabi and other cruciferous vegetables, green leafy vegetables, pomegranate seeds, sesame seeds, tahini, peanuts,  soybeans, beans, brown rice, whole grains.

Food Sources of Betaine:

Sweet potatoes, meats, cheese, beets, basil, spinach, green leafy vegetables, brown rice, whole grains.

Pantothenic Acid – Vitamin B5

Vitamin B5 is typically referred to by its chemical name Pantothenic Acid. Why some of the B Vitamins are called a name and some by the number may have to do with the variety of the forms commonly found in the body or in the food supply. Vitamin B6 has several important chemical forms as do vitamin D and vitamin E. Getting a variety of foods within the diet on a regular, daily, weekly or even monthly basis can help to provide some of the various forms. Vitamin E in a supplement might only provide one of the bioactive forms of the group of nutrients while eating nuts and seeds would be providing some of all of the group in addition to B vitamins and other minerals.

Pantothenic Acid – Vitamin B5. Food sources and symptoms of deficiency.

Pantothenic Acid is a water soluble B vitamin that is essential in metabolic pathways in all forms of life, plants, animals and microbes. It is a precursor chemical for coenzyme A which is involved in many reactions that help sustain life and is needed for other proteins that are needed for making fatty acids – fats of different lengths and types. It does have other active chemical forms but is not typically referred to by their names, pantothenol – may help with healing skin wounds, research is in early stages; and pantethine – may help lower cholesterol and lipid (fat) levels in the blood. (1)

Dietary deficiency of Pantothenic Acid is very rare as the vitamin is found in most animal and plant food products. There have been no known cases of overdose/toxicity so no Upper Limit for safety has been set. Deficiency is so rare it has only been documented in prisoners of war (POWs) and the symptoms relieved by supplementation of Pantothenic Acid were reported by the POWs to be “numbness and painful burning and tingling in their feet.” (1)

Pantothenic Acid is involved in converting the B vitamin folate into an active form so a deficiency in Pantothenic Acid might result in folate deficiency symptoms, (1) (megaloblastic anemia with fatigue and normal levels of iron but with fewer red blood cells that are immature, too large (macrocytic) and nonfunctional (2). Vitamin B12 deficiency can also be a cause with similar lab values but supplements or injections of that B vitamin wouldn’t help if deficiency of the active form of folate was the cause. Supplements of folic acid, the inactive form most commonly used in multi-vitamins or fortified foods, wouldn’t help either. Beans, peas and asparagus are good food sources of folate, more information about that B vitamin is available here: (Folate is essential and Folic Acid is commonly available)

Genetic differences may affect some individual’s ability to phosphorylate (add atoms of the mineral Phosphorus) to the molecule of Pantothenic Acid for the transformation of the vitamin precursor into the bioactive coenzyme A. The enzyme is needed for transporting fatty acids (lipids/fats) into the mitochondria for use for energy production. Someone with a genetic difference might not be able to use fats for energy as well as someone with typical ability to phosphorylate the Pantothenic Acid molecules in the production of Coenzyme A. One known gene that could inhibit the production of Coenzyme A is Pantothenic acid kinase II (PANK2) . Symptoms of people with a double gene difference in PANK2 may include changes in movement control (dystonia), and impaired vision, intelligence, speech, and behavior, and personality disorders (15). (1)

Symptoms of deficiency of Coenzyme A might include gaining weight more easily than average and more readily getting tired when exercising for longer amounts of time. That is my interpretation though.

I have a different genetic difference that affects phosphorylation so I may also have trouble producing Coenzyme A. Betaine-homocysteine methyltransferase (BHMTis a gene involved in protein metabolism that could cause reduced Dimethylglycine and methionine.  Chronic Fatigue Syndrome has been associated with a lack of Dimethylglycine (the amino acid – glycine). The metabolic pathways are very complex chemistry and it looks like this gene is more involved in the chemistry of the B vitamins choline and betaine. The phosphorylation problem is more specifically with phospholipids and  glycerophospholipids – both essential parts of membranes and cannabinoids. (Glycerophospholipid biosynthesis) (Phospholipid metabolism)

I will discuss betaine and choline in additional posts. An overview about phospholipids and food sources is available in the post Macro & micro-nutrients, an overview & food sources.

Symptoms of Pantothenic Acid deficiency in lab animals or other groups of animals found to have deficiency of vitamin B5 in their food supply included skin irritations, graying of fur or feather abnormalities, anemia due to reduced heme production,  nerve problems involving reduced myelin sheath, low blood glucose, rapid breathing and heart rate, and damaged adrenal glands. (1)

So it is good that Pantothenic Acid is readily available in many foods because clearly it is very important to our health. However supplements of Pantothenic Acid or rubbing it directly on the scalp or gray hair did not restore hair color in humans with gray hair. (1)

Food Sources for Pantothenic Acid (vitamin B5):

Organ meats (liver and kidney), Meats, Fish and Shellfish, Salmon, Egg yolk, MIlk, Yogurt, Cheese, Avocado, Broccoli Sweet Potato, Carrot, Celery, Mushrooms, Pomegranate Seeds, Sesame Seeds/Tahini, Beans, Nuts, Seeds, Almonds, Walnuts, Whole Grains, Brown Rice, Enriched Flour Products depending on the source – Canadian guidelines require it while the U.S guidelines do not.  (4, 5) “Processing and refining grains may result in a 35 to 75% loss. Freezing and canning of foods result in similar losses (16).” (1)

Riboflavin – Vitamin B2

Riboflavin (also known as vitamin B2):

Riboflavin, vitamin B2, food sources and possible symptoms of deficiency.

Deficiencies of other B vitamins can cause a deficiency of riboflavin and vice versa. Riboflavin is involved in the metabolism of vitamin B6, niacin, folic acid and iron.  Riboflavin is also needed for metabolism of drugs and toxins and is essential for releasing energy from food.

Alcoholics, anorexics, and people low in other B vitamins are at risk of deficiency but otherwise deficiency is rare.  Riboflavin is in many foods.

Deficiency symptoms may include decreased red blood cell count with normal sized red blood cells; sore throat; magenta/red inflamed tongue, mouth, and throat; sore cracks at the sides of the mouth; and skin rashes.  Deficiency may increase risk of pre-eclampsia and age related cataracts.  Supplemental riboflavin was found helpful for preventing migraines.

Food Sources of Riboflavin (B2) include:

Fortified flour & cereal, whole grains, meats, fish, milk, eggs, meat, fish, beans, nuts, and seeds, nutritional yeast flakes, asparagus, broccoli, yellow summer squash, spinach.

Risks of overdose for water soluble B vitamins and vitamin C are rare:

B vitamins and vitamin C are water soluble, so overdose is rare.  Deficiency is more common because the nutrients are not stored like the fat soluble nutrients:  A, D, E, and K; and water soluble vitamins are not conserved by the kidneys like the electrolyte minerals:  calcium, sodium, magnesium, and potassium.

Riboflavin is a bright yellow nutrient and when taking higher doses in supplements may cause a bright yellow colored urine – it is non-toxic and would be less noticeable, a paler shade of yellow, when plenty of water is also being drunk throughout the day. Any time dehydration is present the color of the urine will be a darker shade and is a good reminder to try to drink plenty of water – 6-10 glasses roughly depending on body size, and amount of exercise performed and the level of heat or humidity in the environment.

Macro and micronutrients: an overview and food sources

Nutrients:

There are two main groups of nutrients: the Macronutrients and the Micronutrients, both of which include many subgroups.  Water doesn’t officially get listed in either group but it is the most essential nutrient as we are mostly water, roughly 70%, with some of the other nutrients holding us together in the form of membranes, muscles, skin and bones. Water helps the blood carry nutrients to the cells and remove waste products to be excreted by the kidneys in the form of urine. Water helps us stay cool in the form of sweat on a hot day. Water is the best thirst quencher and is what our brain expects as a beverage. In nature there is no juice tree, only whole fruit with fiber slowing down digestion of the sweet fruit juice carbohydrates. We need about eight cups of water per day, more on a hot sweaty day and more if diuretic beverages such as coffee or alcohol are consumed. Without water we wouldn’t be able to digest our macro and micro nutrients. So drink and be merry with a glass of water, nature’s favorite thirst quencher! If you think you don’t like it you may just need to try a glass when you are very thirsty, and relax and remember how good it feels, then maybe next time you’re thirsty you’ll reach for a glass of water because it just sounds good.

Macronutrients

Macronutrients are needed in larger amounts within a daily diet because they are used for energy and to build new cells and other body tissue. They include carbohydrates, proteins and fats.

Carbohydrates

Carbohydrates (G.18) are also known as sugars, starches, and fiber. They are all made up of individual molecules of sugars called monosaccharides (See Table 2.4 for images of all the types of monosaccharides: G.13)). Different monosaccharides can be connected to each other as disaccharides which include table sugar called sucrose, or they may be in long chains called polysaccharides which can be straight or branching in widely varied shapes.

Fiber is also made up of monosaccharides but the bond connecting them requires digestive enzymes that humans do not make, so they are considered indigestible but help with fluid balance within the small and large intestines and adequate fiber in the diet can help prevent both constipation or diarrhea. Bacteria ( known as our microbiome) within the digestive system  may be able to break down some types of fiber and convert it into more beneficial nutrients for us, called short-chain fatty acids, which are a type of fat. The types of fiber that can be converted into beneficial fats by beneficial bacteria are called prebiotics and include resistant starches, inulin, gums, pectins, and fructo-oligosaccharides.

Food Sources of Carbohydrates and Fiber: Fruits, vegetables, beans and whole grains are all sources of fiber and carbohydrates. Sources that contain a greater amount of the prebiotic fiber include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas, and seaweed. Raw forms of the vegetables contain more than cooked forms except resistant starches may be increased after the food, such as rice or tapioca starch, is cooked and then chilled. (G.19) Nuts and seeds also contain some carbohydrates and fiber but are more concentrated sources of fats and protein. (G.20)

Food Sources of Essential Monosaccharides (See Table 2.4: G.13):

  • Glucose: Honey from bees. It is one of the monosaccharides of table sugar, the sucrose disaccharide, along with a molecule of fructose. Table sugar may be made from beet sugar or sugar cane. Glucose is also one of the monosaccharides of lactose – milk sugar, and it is part of larger starches found in grains, seeds, and starchy legumes and vegetables such as beans, peas, corn, potatoes, sweet potatoes, and squash and some is found in fruits in addition to fructose. Glucose is also found in “Cocoa, Aloe Vera, Licorice, Sarsaparilla, Hawthorn, Garlic, Echinacea, Kelp.” (G.40)
  • Glucosamine: Animal cartilage released in bone broth – soup stock made with bones; supplements derived from the shells of shellfish such as shrimp, crab or lobster; a few fermented grains. (G.39) Vegetarian sources: “Shitake mushrooms and a red Japanese Algae called Dumontiaceae.” (G.40)
  • Galactose: One of the monosaccharides of lactose, milk sugar, that is found in dairy products or human milk. Some people make less of the enzyme needed to digest lactose and may require a digestive enzyme with dairy products to prevent discomfort and promote better digestion. Anyone may become temporarily lactose intolerant after a severe illness with symptoms of diarrhea as the enzyme is formed in surface cells of the intestine which may need a week or two to regrow after a severe intestinal sickness. Hard aged cheeses have a lower lactose content then soft cheeses or milk and butter products. It is also found in some fruits and vegetables, some herbs including “Echinacea, Boswellia, Fenugreek, and chestnuts.” (G.40) Sour cherries. (G.41)
  • Galactosamine: Beef or shark cartilage, and “a Red Algae called Dumontiaceae (as a constituent of dextran sulphate)” (G.40)
  • Mannose: “Gum Ghatti which is made from the sap of Indian Sumac; Black currants, red currants, cranberries, gooseberries, Aloe Vera Gel from the leaves, Fenugreek, soybeans, green beans, capsicum (Cayenne Pepper), cabbage, eggplant, tomatoes, turnip, Shittake mushrooms and kelp” (G.40) Sweet Cherries (G.41)
  • Xylose: Cranberries, raspberries. (G.15Guava, pears, berries, blackberries, loganberries, raspberries, Goji Berry; Aloe Vera, Echinacea, Boswellia; Psyllium Seeds; Broccoli, Spinach, Eggplant, Peas, Green Beans, Kelp, Okra, Cabbage, Corn.” (G.40)
  • Fucose: “Human breast milk, certain types of mushrooms, seaweed – kelp and wakane, beer yeast.” (G.40) Chanterelle and Penny Bun/porcini mushrooms. (G.42) Maitake, Shiitake, Reishi mushrooms. (G.43) Fucose in human breast milk helps a beneficial type of bacteria called Bacteroides (G.43) become established after the infant is born. It helps protect the infant from more harmful bacteria becoming established in the previously sterile intestinal tract.
  • Glucoronic Acid: Usually formed within the liver as it is a very polarized molecule. It is found in heparan sulfate, dermatin sulfate, and chondroitin 4, 6 sulfate. (G.44)
  • N-Acetylneuraminic Acid (Sialic Acid): “Human breast milk, dairy foods, whey protein isolate, and eggs.” (G.40). After infancy it is generally up to us to make it for ourselves internally. It is electrically polarized and helps stabilize vessel walls by lining the interior and repelling the opposite sides similar to magnets repelling each other.,

Proteins

Proteins (G.17) are made up of molecules called amino acids which, unlike the monosaccharides, can only be connected together in straight chains. The protein chain of amino acids may spiral like the DNA molecule of genetic material or bend in some other way rather than being perfectly straight, and it can then be folded into different 3-dimensional shapes and combined with other protein chains to form larger 3-dimensional shapes. The basic structure is straight though like a string of beads or a sentence of letters.

The monosaccharides can connect to each other in multiple places and form more complex shapes like a crossword puzzle of letters or a branching tree made up of letters. This difference is important for the immune system as the complex antigen/antibody recognition seems to be based on the language spelled out by the types of monosaccharides on the antigens found on the surface of cells. Antibodies are made by immune cells to help the immune cell recognize foreign proteins or mislabeled or defective human cells. Antigens and antibodies contain monosaccharides and proteins or lipids. The combined molecules are known as glycoproteins and glycolipids. The combination makes it possible for them to do more complex chemical functions within the body than a simpler protein, carbohydrate or fat molecule. (G.14)

Food Sources of Protein: Dairy products, eggs, meats, poultry, and fish provide all the essential amino acids that humans can not convert from other molecules. Grains, beans, peas and lentils, nuts and seeds, and other vegetables provide protein but most are missing a few of the essential amino acids that we need to consume from our daily diet. (G.17) Fruits and other vegetables also provide some protein but in smaller amounts. Avocado, dried figs, melon and nectarine, artichokes, broccoli, Brussel sprouts, corn, mushrooms, spinach and potatoes are slightly better sources than other fruits and vegetables. (G.23) (G.24)

  • The nine essential amino acids are:  histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. (G.21) Beans/ legumes and nuts/seeds and grains provide balance within a meal by providing some of each of the essential amino acids. Grains are good sources of methionine, tryptophan and cysteine while legumes/beans/nuts/seeds are lower in those amino acids except for soy beans and nuts/seeds which are a good source of tryptophan. Grains, nuts, and seeds are low in isoleucine and lysine while legumes/beans are a good source of them. (G.22)
  • Conditional amino acids  may not be able to be made during illness or stress and would be required from the diet for better function and health: arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine. (G.21)
  • Non-essential amino acids can be regularly produced in the body and include: alanine, asparagine, aspartic acid, and glutamic acid. (G.21)  Excessive amounts of aspartic acid and glutamic acid from dietary sources may have negative health effects due to their ability to increase activity within brain cells and are also known as excitotoxins. Mono-sodium glutamate and other seasoning ingredients are sources of glutamic acid and the artificial sweeteners Nutrasweet/Aspartame/Neotame are sources of aspartic acid.

Fats

Fats are also known as oils, lipids, and as essential fatty acids, or trans fats which may be formed during processing of other fats or found ins some animal products naturally. The artificially produced trans fats may increase heart disease risk and it is recommended to limit their use in the daily diet. Molecules of fats can be found as short chain fatty acids or long chain fatty acids which may be then be joined into small groups called triglycerides. Branched chain amino acids are also possible but the branching is somewhat different than the type formed by monosaccharides.

The chains of fats may include more or less hydrogen molecules. Saturated fats have more hydrogen molecules, monounsaturated fats are missing one hydrogen molecule and polyunsaturated fats are missing several along the chain. The point in the molecule without a hydrogen is more reactive. Saturated fats are more stable than polyunsaturated fats. Monounsaturated fats may be more helpful for reducing risk of heart disease while saturated fats may increase risk. However we do need a variety of the types as each type is involved in different ways throughout the body. Omega 3 fatty acids and omega 6 fatty acids are polyunsaturated fats that have important roles in health and help reduce risk of chronic illness. Phospholipids are a combination of a lipid with the mineral phosphorus. They are important for helping make flexible membranes and play a role in immune health and energy metabolism.

Food Sources of Fats: Avocado, coconut, coconut oil, olives and olive oil, nuts, seeds, and oils, butter, dairy products, egg yolk, meats, poultry, fish.

While all the sources have a mixture of specific types of fats some sources have more of one or two of the types:

  • Food Sources of Saturated Fats: Animal products such as butter, cheese, and other high fat dairy products; marbled beef and higher fat processed meats; palm oil and palm kernel oil; coconut and coconut oil. The effect on the body can vary based on the source while too much of any fat is a problem the coconut products have other healthy nutrients while the palm oil and palm kernel oil may promote increased insulin levels and increase appetite. The production of palm and palm kernel oil also may be worse for the environment and cause loss of wild animal habitat. (G.27)
  • Food Sources of Mono-unsaturated Fats: Olives and olive oil, canola, sesame, safflower and sunflower oils, peanut oil and peanut butter, almonds, avocados, cashews, peanuts, eggs, red meat, tea seed oil (Camellia seed). (G.33) (G.34)
  • Food Sources of Poly-unsaturated Fats: Nuts and seeds and oils made from them; salmon and shellfish (G.28).
  • Food Sources of Trans Fats: Margarine and other products made with hydrogenated oils such as coffee creamer,(G.35), commercial baked goods such as frosted desserts or cookies, biscuits, doughnuts, crackers, microwaveable breakfast foods, microwave popcorn, frozen pizza, fried fast foods, cream filled candies. (G.36)
  • Food Sources of essential Omega-3 Fatty Acids, including EPA and DHA: Fatty fish such as sardines, tuna, herring, lake trout, and salmon, omega 3 enhanced eggs, omega 3 fortified dairy products, and seaweed,(G.37), shellfish, (G.28) krill and krill oil, (G.38), and vegetarian sources that contain a precursor include flax seeds, walnuts, canola, soybean and walnut oils, beans and tofu and other soy foods, and leafy greens.(G.37)
  • Food Sources of essential Omega-6 Fatty Acids, including Gamma Linolenic Acid (GLA): Borage oil, black currant oil, hemp seed oil; butter made from milk from cows that were grass fed; spirulina/blue-green algae. (G.25)
  • Food Sources of Phospholipids and other phospho-nutrients: Hemp seed kernels and oil; Artemisia turanica/wormwood leaf; amaranth seed; asparagus; avocado fruit or the inner kernel, dried and powdered; beans/legumes; cardamom seeds and powder; carrots; celery stalks and leaves; cocoa beans and cocoa powder, baker’s chocolate, dark chocolate and to a lesser amount milk chocolate and chocolate syrup; coconut; cumin seed/powder; fennel seed, flax seed, pine nuts; sesame seeds, pumpkin seed kernels, squash seeds; butternut squash and pumpkin; gingko leaf; grapefruit and orange juice with the pulp; Jerusalem artichoke (this is a root vegetable rather than a green artichoke); lettuce, spinach and mustard leaves and other leafy green vegetables and herbs; nuts/peanuts, cashews, walnuts; oats; okra seeds; onion root, leek leaves, garlic;  parsnip root; pomegranate seeds and pomegranate peel extract;rice, white or brown but the bran is the best source; rosemary; sorghum;  sweet potato or yam; buckwheat (a seed botanically that is not wheat and is gluten free); wheat. (G.26)

Micronutrients

Micronutrients are needed in smaller amounts within the diet and some can be stored by the body and reused so they may not be needed in the diet everyday as long as they are being eaten occasionally; while others can not be stored and are needed in the diet everyday. Micronutrients include vitamins and minerals. Minerals may be needed in slightly larger amounts or smaller amounts and the ones needed in smaller amounts are also known as trace minerals – because we only need them in trace amounts. Vitamins are grouped into fat-soluble vitamins which can be stored in the body and may not be needed in the diet everyday as long as they are included weekly or monthly depending on the nutrient. Water-soluble vitamins can not be stored and need to be included in the diet everyday for ideal health.

Minerals

Food Sources of some important Minerals:

  • Calcium: dairy products and fortified substitutes made from almond, soy, rice or hemp. Sesame seeds, almonds and other nuts, seeds and beans. Canned salmon and sardines.
  • Magnesium: oat bran, beans, nuts, seeds, whole grains, leafy green vegetables, chocolate, and molasses.
  • Phosphorus: most foods contain this nutrient, particularly dairy and protein rich foods, also cereals, nuts and beans. An excess may be provided if carbonated beverages are used regularly.
  • Potassium: all fruits and vegetables and juices are the richest sources, but animal products also contain some potassium.
  • Sodium: processed foods containing salt and added table salt are the main sources but use of “softened” water can also increase a person’s daily intake of sodium.
  • Chloride: table salt and processed foods also provide the electrolyte, chloride.
  • Iron: meat, poultry and fish and shellfish (G.28) contain a form called heme iron which is more readily absorbed. Vitamin C eaten along with whole grain or beans, nuts and seeds can help increase absorption of non-heme iron.
  • Iodine: iodized salt and processed food made with iodized salt. Seaweed and coconut products and any other produce grown near the ocean may contain more iodine than produce grown inland.
  • Selenium: selenium is also more available near coastal waters. Seafood and meat can be better sources and Brazil nuts provide more than other foods. Two Brazil nuts per day may provide the 200 mcg recommended for daily needs. Excess intake regularly may cause toxicity symptoms. One milligram or more per day may cause vomiting, loss of hair and nails and skin lesions. (Nutrition & Diet Therapy, 8th Ed.)
  • Zinc: shellfish, (G.28), beef, dairy products, nuts, beans, pumpkin seeds. (G.zinc)
  • Copper: shellfish, (G.28); organ meats such as liver and kidney; cocoa and chocolate; beans such as lentils, nuts such as almonds, sunflower seeds, potatoes, asparagus and leafy greens; mushrooms, dried fruits such as apricots and prunes; blackstrap molasses, black pepper, and yeast. (G.29) (G.30) The modern diet may tend towards too much copper and not enough zinc and the two minerals need to be in balance with each other for optimal physical and mental health. Excess copper and deficient zinc is associated with mental illness symptoms.

Vitamins

Food Sources of some important Vitamins:

  • Thiamin (B1): fortified flour or rice, whole grains, pork, beans, nuts, nutritional yeast, eggs, cantaloupe, green vegetables.
