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.

Intermittent Fasting – What the Science Says

IntermittentFastingSusan Brown Health and Wellness EditorIntermittent fasting for general wellbeing and weight loss may seem like a relatively recent dietary trend. However, the origin of intermittent fasting can be traced back to our hunter-gatherer ancestors, when a successful hunt was a time for feasting, and an unsuccessful one resulted in hunger or a period of fasting. Several hundred indigenous hunter-gatherer tribes remain in the Amazon forests, the African grasslands, the Arctic tundra and the remote islands of Southeast Asia. Their diets still consist of what they hunt or gather: game, fish, honey, and plant foods, such as tubers, berries, nuts, and fruit, and in most cases very little cultivated food. Studies of the Tsimane people, a forager-horticulturalist indigenous population of the Bolivian Amazon, reveal highly diverse microbiomes, the lowest levels of vascular aging for any population, and low levels of atherosclerosis and heart disease, likely associated with their low blood pressure, blood sugar and LDL cholesterol levels.

Perhaps it’s healthier to eat more sparingly, as our bodies are adapted to alternating phases of food abundance or scarcity. We would likely all be better off if we ate local fruits and vegetables, a little meat, fish and some whole grains, and were physically active for an hour or more a day. With the advent of bountiful agriculture and animal farming, the food supply became predictable and abundant, eventually leading to our current unhealthy highly processed modern diet. Today, food is continually available, and overeating is the norm. With the rising epidemic of obesity, diabetes and other diet related diseases, some wonder if we gave up a healthier diet, and consequently healthier bodies, in exchange for food security. In addition to a healthy varied diet, what if we were to skip a few meals each week, or fast every other day, or shorten the hours in which we consume food? Would we be stronger, leaner, healthier and  more energetic?

Animal studies have shown that reducing typical caloric consumption extends life span by a third or more. While the jury is still out on whether reduced intake will  increase human lifespan, data supports the idea that caloric restriction supports healthy weight maintenance, reduces the risk of developing age-related chronic and degenerative conditions, and lengthens the period of life spent in good health. Mark Mattson, head of the National Institute on Aging’s neuroscience laboratory believes that “intermittent fasting acts in part as a form of mild stress that continually revs up cellular defenses against molecular damage,” and ramps up our cellular detoxification system that rids the body of damaged molecules previously tied to Alzheimer’s, Parkinson’s and other neurological diseases. While not everyone agrees, researchers are focusing on intermittent fasting as a promising alternative to continuous caloric restriction for both weight loss and health promotion.

Intermittent fasting can be personalized to individual preferences:

  • The 16/8 method involves restricting your eating window to 8 – 10 hours and fasting for 14 – 16 hours daily. Hours can be flexible, but it basically means not eating until noon each day and finishing the last meal by 8 pm. Those who already skip breakfast may find this an effortless way to lose weight, as long as healthy foods are consumed during the eating hours. Those who are hungry first thing in the morning may initially find this method difficult.
  • The 5:2 diet involves eating normally five days a week and consuming two small meals totaling 500 -600 calories on two days of the week. This method may be more sustainable for long-term weight management.
  • Some choose the alternate day fasting method, which allows only 500 calories every other day. This is likely too restrictive and unsustainable long-term for most people.
  • The warrior method allows small amounts of vegetables and fruits to be eaten during the day and the consumption one large meal at night. With this method, paleo foods are preferred.
  • Spontaneous meal skipping is the least structured fasting plan where meals are skipped from time to time, essentially when one is not that hungry, can’t really decide what they feel like eating, or when stopping to eat is inconvenient. This method is basically effortless, but not the most effective for weight loss.

What happens when you fast? The body initiates important cellular repair processes, the metabolic rate increases, and insulin levels drop significantly, facilitating fat burning and weight loss. Lower insulin levels, higher growth hormone levels, and increased amounts of norepinephrine all enhance the breakdown of body fat, enabling its use for energy production. Fasting may also enhance the body’s resistance to oxidative stress and may help fight health damaging inflammation. While intermittent fasting can be a powerful weight loss tool, food quality is crucial. While some tout binging during the eating windows, to lose weight and improve health, a healthy whole food diet is necessary. In conclusion, intermittent fasting may be a reasonable alternative dietary strategy for those who find the more traditional daily caloric restriction difficult or time consuming.
