A, D, E, and K – The Fat Soluble Vitamins

FatSolubleVitaminsJacquie Eubanks RN BSNInfluenced by their molecular properties, the solubility of nutrients determines how well they will be absorbed by the body. Whether a vitamin is soluble (dissolvable) in water or in lipids influences where it can be utilized and whether any excess will be excreted or stored. Water-soluble B-complex vitamins and antioxidant vitamin C are quickly and easily utilized; any excess intake is eliminated so daily replenishment is required. Not surprisingly, fat-soluble vitamins A, D, E and K require some dietary fat in order to be absorbed and metabolized. Excess intake of these nutrients is stored in the liver and the body’s fatty tissues until needed. Dietary fats are also required for the conversion of carotene to vitamin A, for mineral absorption, and for numerous biological processes. Vitamins A, D and K cooperate synergistically, and also work in tandem with important essential minerals like magnesium, calcium and zinc.

Nutrient deficiencies are generally the result of dietary inadequacy, impaired absorption, increased requirement, or increased excretion. While a well-balanced diet containing a wide variety of nutrient dense whole foods can provide sufficient amounts of vitamins and minerals, nutrient deficiencies are incredibly common. Unlike vitamins A, E and K that have multiple dietary sources, very few foods naturally contain vitamin D. As food sources are limited, a deficiency can occur when dietary intake is insufficient over a period of time. Since vitamin D is synthesized through skin exposure to ultraviolet radiation from sunlight, restricting sunlight exposure can also create a deficiency of this nutrient. Additionally, low serum levels of vitamin D can result from inadequate digestive absorption, or the inability of the liver and kidneys to complete the synthesis of vitamin D from ultraviolet light.

Vitamin A

Also known as retinol, antioxidant vitamin A is critical for the maintenance of normal vision, as well as the growth and specialization of virtually all bodily cells. Vitamin A has important roles in embryonic development, normal immune functions, red blood cell production and free radical scavenging. Naturally present in foods such as organ meats, salmon, dairy products and colorful fruits and vegetables, vitamin A is actually a group of nutritional organic compounds that include retinol, retinoic acid, and provitamin A carotenoids, most notably beta-carotene. Although it is best known for the ability to support eye health, vitamin A also helps to relieve inflammation and supports bone, immune, skin and tissue health.

Vitamin D

All vitamin D, whether obtained through sunlight exposure, diet or supplementation, is biologically inert. To become biologically active it and must go through conversion, first in the liver, then in the kidneys. As optimizing vitamin D levels is important to disease prevention and long term health maintenance, one must expose large amounts of skin to the proper amount of sunlight, or supplement with vitamin D3, a highly potent, quickly converted bioactive form. Actually considered a prohormone, vitamin D has the potential to provide numerous health benefits when adequate levels are maintained. Among its many functions are the facilitation of calcium, phosphate and magnesium absorption, cell growth modulation, and inflammation reduction, as well as immune and neuromuscular support. Vitamin D may play a role in protecting against certain cancers, heart disease, diabetes, stroke, autoimmune diseases and depression. As many individuals either avoid sun exposure or block ultraviolet rays with sunscreen, supplementation with vitamin D3 may be a wise choice for those who with low serum levels of vitamin D.

Vitamin E

Required for the proper function of many organs, enzymatic activities and neurological processes, antioxidant vitamin E fights free radicals, helps reduce inflammation, and works to balance hormones naturally. Found in seeds, nuts, whole grains and some fruits and vegetables, vitamin E helps boost immunity and supports blood vessel health. Although more studies are needed, vitamin E may support cardiovascular health by helping to prevent platelet clumping and plaque buildup in blood vessels. Through its ability to fight the inflammation and oxidation linked to numerous health conditions, vitamin E may aid in the prevention of cataracts, arthritis and some cancers.

Vitamin K

Well known for its crucial role in proper blood clotting, vitamin K is also essential for building strong bones and preventing heart disease. Of the three types of vitamin K, K1, K2 and K3, natural vitamin K2 is synthesized in the digestive tract and is the form most often recommended for supplementation. Viewed as an important nutritional intervention for improved bone density, vitamin K2 aids the deposit of calcium and other important minerals into the bone matrix. Additionally, published research has indicated that optimum intake of vitamin K plays an important role in longevity. By aiding calcium placement in the bones, vitamin K helps to keep calcium deposits out of arteries and blood vessels, thereby preventing  arterial calcification, or atherosclerosis, that can lead to heart attacks and stroke. Primarily present in leafy vegetables, vitamin K can be found in fermented foods and animal products, such as meat and dairy.

It can be nutritionally challenging to get the macro- and micro-nutrients the body requires, particularly when one is elderly or dieting, or has illnesses, allergies, or dietary restrictions that require the elimination of entire food groups. The result of sub-optimal intake of nutrients is a sub-optimal state of health. RDA’s, known also as Daily Values (DV), are typically based on a 2,000 calorie per day diet. With diet alone, the average American will fail to meet RDA’s for B vitamins, vitamin D, and minerals such as iron, magnesium and zinc. Even those who consciously eat a nutritious diet each day may fall alarmingly short of their RDA’s for maintaining optimal health.

Nutrients for Optimum Oral Health

NutrientsOralHealthJacquie Eubanks RN BSNIncreasing evidence shows that the state of overall health is directly linked to the health of the oral cavity. Oral hygiene, eating patterns and food choices all play important roles in oral health, including the health of teeth and gum tissue, as well as cavity and disease prevention. Poor oral hygiene raises the risk of cavities, halitosis, gum disease, and tooth and bone loss. Salivary fluid and many mouth surfaces host a vast and highly diverse microcosm of bacteria, some associated with the digestive process, and others with oral health or disease. Heavily influenced by inadequate nutrition, poor oral hygiene, age, illness, medications, hormonal changes and tooth eruption or loss, pathogenic bacteria can cultivate and cause swollen and bleeding gums, and lead to more serious periodontitis.

Periodontitis is defined as a gum infection that damages the soft tissues and destroys the bone that supports the teeth, resulting in tooth loss. Largely preventable, periodontitis generally results from improper brushing and flossing, the failure to have regular dental checkups and tobacco use. Symptoms of unsightly red, swollen, tender, receding, and bleeding gums warrant a visit to a dentist to halt the progression and permanent destruction of connective tissues and bone. The threat of tooth loss from periodontal disease is traumatic on its own. Perhaps even more worrying, science shows that periodontal pathogens can enter the blood stream and contribute to inflammation and other serious health complications, including coronary artery disease, respiratory problems, rheumatoid arthritis, certain cancers, and endocarditis, an infection of the lining of the heart.

As the relative risk of cardiovascular disease may be doubled in people with periodontal disease, investing in your oral health is an investment in your overall health. Nutrition is an integral component of oral health, as diet affects the integrity of the tooth structure, the composition of saliva and pH balance. Science confirms the relationship between a diet high in refined carbohydrates, sugars and starches and the production of plaque acids, that attack tooth enamel. Reducing between meal snacking, cutting back on starchy refined carbs, and avoiding sugary foods and drinks, helps to prevent tooth decay by limiting the time that sugars are available to microorganisms. Fiber-rich fruits and vegetables help to stimulate saliva flow that provides natural cavity defense and helps to neutralize acids that harm the teeth.

To support your oral health, avoid foods that have a high potential for tooth decay, including hard and soft candy, baked goods and dried fruit, as well as foods that have a moderate potential for decay, such as fruit juice and other sugary beverages. If you are going to have juice, soda or desert, its best to have them with a meal and when possible, brush immediately or at least swish with water afterwards. Eat more foods that have low potential for decay, such as raw vegetables, whole fruit, and dairy without added sugars. Foods that have a very low potential for decay include meats, fish, poultry, fats and oils. Certain foods, such as cheese, xylitol and nuts, may have the ability to actually prevent decay.

A well-balanced diet, along with sufficient intake of the following nutrients, vitamins and minerals can support and promote oral and dental health:

Vitamin C and quercetin work synergistically to reduce inflammation, fight against cell damage and build, protect, repair, and maintain gum tissue health. As a powerful antioxidant, vitamin C supports immune health and the healing process. Clinical evidence supports the role of vitamin C in preserving periodontal heath.

CoQ10 and its reduced form, ubiquinol, promote tissue health and healing, support energy production and help prevent free radical damage.

Calcium and phosphorus work to build and strengthen bones and teeth and provide structural support for bones. Calcium is stored in bones and circulates in small amounts throughout the blood stream. Sufficient intake of calcium supports bone strength and tooth enamel integrity.

Potassium works with magnesium to help boost bone mineral density and may keep calcium from becoming too acidic, helping to prevent calcium leach from bones.

Vitamin D helps regulate musculoskeletal heath by mediating calcium absorption and mineral homeostasis. Vitamin D insufficiency affects bone mineral density, and increases the risk of infectious and inflammatory chronic diseases. Vitamin D supports oral health by positively affecting bone metabolism, functioning as an anti-inflammatory agent, and stimulating the production of anti-microbial peptides.

Vitamin K2 works synergistically with calcium and vitamin D to help move calcium into bones and teeth, and helps to produce osteocalcin, a key protein used in bone remodeling. Vitamin K2, particularly in MK-7 form, may help to keep chronic inflammation at bay.

Vitamin A promotes saliva production, helping to prevent potential cavity-causing dry mouth, and helps to maintain healthy mucous membranes that coat gum tissues and cheeks.

Interest in probiotics for oral health is steadily growing, as probiotic bacteria appear to beneficially affect both oral microbiota and the immune response. Some studies have found the probiotics may improve overall gingival health by decreasing gingival inflammation and reducing gum bleeding.

Eye Health Support

EyeHealthJacquie Eubanks RN BSNDesigned as an adjunct to a healthy diet, researched backed nutritional supplements have been shown to be beneficial for the maintenance of vision and eye health. Ongoing research continues to explore health protective nutrition in prevention of age-related eye changes that can cause visual disturbances and the loss of visual acuity. Beginning around age 40, adults may start to notice vision changes, such as an inability to focus on near objects, the need for brighter lights in reading or work areas, and changes in color perception, as well as reduced tear production, resulting in dry, irritated eyes. As we continue to age, the risk for developing eye and vision problems increases. Early warning signs of eye health problems can include:

Vision fluctuation – Vision that fluctuates throughout the day can be attributed to several causes, including general fatigue, eye muscle spasms resulting from intense focusing for an extended period, or progressing presbyopia, a common age-related inability to focus on near items, such as a newspaper or menu, especially in dim light.

Eye floaters and flashes of bright light – Specks or thread-like images that appear in the field of vision are generally harmless and may become less noticeable with time. Floaters indicate that the vitreous humor, a gel-like substance that makes up a large majority of the eye behind the lens, is slowly shrinking with age, creating strands that cast their shadows on the retina. Flashing occurs when the vitreous gel tugs or bumps the retina. Although floaters and flashers can be annoying, they are generally considered harmless. However, a new onset of floaters or increased flashes can signal more serious vision problems, such as retinal detachment or a retinal tear, requiring a visit to your ophthalmologist as soon as possible.

Loss of peripheral vision – Peripheral or side vision is the ability to see movement and objects located outside your central or direct line of vision. Also known as tunnel vision, loss of wide angle vison is commonly the result of optic nerve damage, resulting from glaucoma, a detached retina, brain or neurological damage or a head injury.

Distorted images – Wavy or blurred images or loss of central vision may be signs of age-related macular degeneration, the leading cause of vision loss among adults aged 50 and older. Although there are exceptions, macular degeneration generally progresses slowly. The greatest risk factor is aging, making regular comprehensive eye exams crucial for seniors. Additional risk factors include diabetes, genetics, and side effects of medications taken for chronic conditions.

A colorful and varied diet, rich in omega-3 fats, whole fruits and dark green leafy vegetables is emphasized for eye, vision and overall health. As well, protecting your eyes from ultraviolet light, avoiding smoking, reducing screen related eye strain, exercising regularly, and maintaining a healthy weight along with normal blood pressure and cholesterol levels, may help to prevent macular degeneration or slow its progression. Age Related Eye Disease (ARED) studies revealed that antioxidant multivitamins can help to protect against progression to advanced stages of macular degeneration in those who have been diagnosed with the condition.

Poor diet resulting in inadequate nutrition is associated with many serious health conditions including vision loss. Research shows that vitamins and nutrients that help reduce inflammation and control oxidative stress are beneficial for maintaining eye and vision health and may offer protection from degenerative diseases, including macular degeneration and cataracts.

Vitamin A promotes good vision, especially in low light. Well known for its supportive role in healthy vision and prevention of night blindness, vitamin A helps to protect the cornea and mucous membranes of the eye surface, helping to reduce the risk of eye infections.

B Complex vitamins help to reduce chronic inflammation and elevated homocysteine levels associated with retinal vascular problems. B vitamins may also help reduce the risk of macular degeneration.

Vitamin C has powerful antioxidant properties that help protect the eye lens by preventing oxidation, which can result in a clouded lens associated with cataract formation.

Vitamin D sufficiency is associated with a lower risk of macular degeneration, while a deficiency is strongly associated with dry eye and its level of severity.

Lutein and zeaxanthin are carotenoids that are found in the eyes. Many studies have shown that lutein and zeaxanthin support eye health and reduce the risk of chronic eye diseases, including cataracts and macular degeneration.

Omega-3 essential fatty acids, DHA and EPA, are among the most important nutrients for proper visual development, retinal function, and life-long eye maintenance. DHA is found in the highest concentration in the retina. Omega-3 deficiency is linked to dry eye syndrome, diabetic retinopathy and age related macular degeneration. Essential fatty acids help to restore and maintain tear formation and eye lubrication.

Bioflavonoids are pigments responsible for giving plants, fruits and vegetables their vibrant colors. These biologically active antioxidant and anti-inflammatory compounds aid the absorption of vitamin C, help increase antioxidant efficiency, and support capillary health, including eye capillaries.
