February 2. 01. 5 Issue. Plan Healthful Vegan Diets. By Virginia Messina, MPH, RDToday's Dietitian. Vol. 4. 0Learn how to better counsel vegan clients and patients so they can meet nutrient needs and avoid shortfalls. People choose to become vegans for a variety of reasons. The number of vegans as a percentage of the population is relatively small—about 2% of US adults. In fact, most dietetics professionals can expect to work with vegan clients and patients periodically. Vegan diets exclude all meat, fish, poultry, dairy products, and eggs.

For example, most commonly available cane sugar is processed using bone char and may not be acceptable to some vegans. Evidence on the health benefits of vegan diets comes from two large prospective epidemiologic studies: The Adventist Health Study- 2 in North America, and the EPIC- Oxford study in England. Findings show that vegans typically have lower BMIs,2 a decreased risk of type 2 diabetes,2 reduced blood cholesterol levels,3 and a probable reduction in hypertension. Rates of heart disease are lower among vegan men but not women,5 and vegans may have a lower risk of certain cancers. ![]() The factors that may be responsible for these health benefits include a higher intake of fiber, fruits, vegetables, nuts, and legumes, and lower intakes of saturated fat and cholesterol. At the same time, research suggests that calcium intakes often are low in vegans. Those who don't supplement also may have low or marginal vitamin B1. D,1. 1 iodine,1. 2 and omega- 3 fatty acid status. ![]() Because of antinutrients in plant foods, there also are challenges in meeting needs for iron and zinc. As a result, RDs must take all of these nutrients into consideration when helping clients plan a vegan diet. The good news is that nutrient shortfalls are easily avoided on vegan diets as long as clients pay attention to food choices. Calcium From Plants. Several decades ago, the acid- ash hypothesis of osteoporosis suggested that calcium needs might be lower in diets that exclude or limit animal proteins. According to this theory, modern Western diets, which are rich in animal protein, result in higher endogenous acid production, which promotes higher rates of bone turnover. More recent research has challenged the acid- ash hypothesis of osteoporosis and newer theories suggest that protein is protective for bone health and not detrimental. Unfortunately, many popular vegan websites and books continue to suggest that vegans have lower calcium requirements due to the absence of animal protein from their diets. This may be one reason why many vegans don't meet the recommended dietary allowance (RDA) for calcium. Some evidence suggests that these lower intakes are associated with higher fracture risk. As a result, it's important for dietitians to assist vegan clients in identifying calcium- rich plant foods that can help them meet current RDAs for calcium. Bioavailability of calcium from plant foods varies over a wide range. Absorption of calcium from the cruciferous vegetables collards, kale, mustard greens, turnip greens, bok choy, and broccoli, can be as high as 6. Theoretically, vegans could meet the biological requirement for calcium with a lower total calcium intake if most of it comes from these highly bioavailable sources. For example, 1 cup of cow's milk contains nearly twice as much calcium as 1 cup of bok choy, but the amount of calcium absorbed from both is similar. Most plant milks made from almonds, soybeans, hempseeds, cashews, and rice are fortified with calcium in amounts similar to the levels in cow's milk, and absorption rates also are similar. Calcium- set tofu, made with calcium sulfate, also can be an excellent calcium source. Other foods such as white beans, soybeans, chickpeas, sesame tahini, navel oranges, and figs contribute moderate amounts of calcium. While grains, legumes, vegetables, nuts, and seeds provide all essential amino acids, their amino acid pattern is a poorer match to human needs compared with animal proteins. A longstanding recommendation was to consume plant foods in complementary combinations during meals to supply an optimal amino acid pattern. It's now recognized that complementary proteins don't need to be consumed at the same meal. Instead, a variety of plant foods consumed over the course of a day will provide adequate essential amino acids. Furthermore, the body maintains a pool of essential amino acids that are available for protein synthesis. These come from a number of sources, including sloughed intestinal cells and digestive enzymes. However, dietitians should be mindful of a couple of important issues regarding vegan protein needs. First, vegan diets that don't include legumes may fall short of meeting needs for the essential amino acid lysine even if total protein needs are met. Grains and beans typically are low in this amino acid, and consuming enough of these foods to meet the protein RDA wouldn't ensure that the RDA for lysine is met. Therefore, vegans should consume at least three daily servings of legumes, which are rich in lysine. A second issue is that protein needs may be approximately 1. This translates to 0. This amount of protein is easily supplied when vegans consume a variety of plant foods, meet calorie needs, and include legumes in their meals. Enhancing Iron and Zinc Absorption Legumes, whole and enriched grains, and some vegetables and dried fruits are especially rich in iron. Vegan diets often are higher in iron than omnivore diets and are frequently higher in iron than lacto- ovo vegetarian diets since dairy foods are a poor source of this nutrient. The issue in vegan diets is iron bioavailability, since the nonheme iron in plant foods is often bound to phytates, resulting in poor absorption. Other dietary factors, especially vitamin C, counter the effects of phytate. A meal including just 5. C (the amount in 1/2 cup of cooked broccoli) can significantly affect absorption. Importantly, the vitamin C must be present at the same time as the iron. Therefore, vegans should give some attention to including good sources of vitamin C in as many meals and snacks as possible. The best sources of zinc in vegan diets are legumes, nuts, and seeds. Vegan diets often are lower in zinc compared with diets that include animal foods, however, and zinc from plant foods has lower bioavailability. Both minerals are better absorbed from leavened bread through the fermenting action of either yeast or sourdough. Toasting nuts and seeds also can improve zinc absorption as can sprouting legumes and grains. Dietary Fat. Vegan diets typically are somewhat lower in total fat than diets containing animal products and are significantly lower in saturated fat. Even with their reduced fat intake, vegans have no trouble meeting needs for the essential omega- 6 fatty acid linoleic acid, which is widely available in the food supply. In contrast, the essential omega- 3 fatty acid alpha- linolenic acid (ALA) is found in significant amounts in only a handful of plant foods. The best sources are ground flaxseed (the fat is poorly absorbed from whole flaxseed), and walnuts. Walnut, canola, and flaxseed oils also provide ALA. One or more of these foods should be included in vegan diets daily. Like all people who don't eat fish, vegans have low blood levels of the long chain omega- 3 fatty acids DHA and EPA. Although these fats can be synthesized from the essential fat ALA, the process is inefficient in many people. It's unclear whether the lower levels in vegans are harmful, but it may be wise for them to follow recommendations of major health organizations to supplement with these fats. Vegan supplements of DHA and EPA derived from microalgae are available. Fat- rich plant foods such as nuts, seeds, and healthful vegetable oils, including olive, walnut, soy, and canola, also can help vegans meet nutrient needs, provide phytochemicals for reducing chronic disease risk, and improve absorption of fat soluble nutrients and phytochemicals. Nuts and seeds are particularly important for providing zinc. Essential Supplements All vegans need to take a vitamin B1. There are no known plant foods that are natural sources of vitamin B1. Some foods that have been credited with providing vitamin B1. B1. 2 analogues that have no actual vitamin activity. But misinformation on popular vegan websites and in books may encourage vegans to depend on these foods to meet their requirements. Not surprisingly, research consistently shows suboptimal B1. Vegans should choose supplements containing cyanocobalamin, which is the form of the vitamin that has been well studied. Limited research suggests that methylcobalamin can be effective in maintaining a healthy B1. Because vitamin B1. The RDA of 2. 4 mcg assumes consumption of small amounts of vitamin B1. Those who consume fortified foods, including breakfast cereals, plant milks, and vegetarian meats can opt for two servings per day of foods fortified with at least 1. B1. 2 per serving. For vegans who get all of their B1. Most B1. 2 supplements contain much higher doses than this, however, and some vegans may prefer to take a supplement providing 1,0. Vitamin D supplements or fortified foods are recommended for anyone who lacks adequate sun exposure regardless of the type of diet followed. Ethical vegans may opt for supplements of vitamin D2, ergocalciferol, which is derived from yeast or mushrooms exposed to ultraviolet rays. The more common vitamin D3, cholecalciferol, is derived from animals. Both forms of the vitamin are absorbed and raise blood levels of 2. D, although vitamin D3 is somewhat more effective than D2. Because levels of vitamin D2 may decline more quickly than those of vitamin D3, it's important for vegans to take daily supplements rather than larger doses less frequently.

Because of the desire for options beyond surgery, chemo and radiation for dog cancer, I chose to look in areas that I would have ignored just a few years back. One of the hottest topics in cancer research right now is the dietary flavonoid group. In this way big pharma protects profits. Secondly, curcumin has some bioavailability problems. This means that the stuff doesn’t, to a large extent, get absorbed into the blood after it is taken by.
