www. superfoodhealthyliving. com www. superfoodhealthyliving. com One universally recognised effect of a high raw diet is weight loss, and many leading exponents of raw diets report being overweight on a conventional diet but achieving a desirable weight on switching to a raw vegan diet. This effect is no mystery as raw plant foods are generally low calorie density high fibre foods which are very filling – ideal for weight loss – and was confirmed by a six-month trial in South Africa. A common reason for abandoning raw food diets, however, is excessive weight loss. Including sufficient tropical fruits such as bananas and avocados, or nuts and seeds and cold pressed oils, is important for maintaining a healthy weight once any desired weight loss has been achieved. Increasing the consumption of raw fruits, nuts and salad vegetables considerably beyond current UK average intakes can be expected to be benefit individual health and to benefit the environment if locally produced. However, evidence to date does not justify a general recommendation of raw vegan diets in the sense of more than 80% of food being consumed raw, particularly for children who need a relatively high calorie density. The Vegan Society recommends the consumption of a wide variety of plant foods, including raw fruit and salads and cooked foods including a wide range of vegetables and whole grains. It also strongly recommends the consumption of 3 micrograms per day of vitamin B12 from fortified foods or . . .

www. superfoodhealthyliving. com www. superfoodhealthyliving. com Food processing destroys some nutrients, but can also inactivate toxins and increase the availability of other nutrients. Conservative cooking such as steaming or boiling causes only modest loss of some nutrients, such as folate, while enhancing the bioavailability of others, such as carotenoids. Lycopene, which appears to have profound protective effects on health, is better absorbed from cooked than from raw tomatoes. Liquidising or juicing also increases carotenoid availability from carrots. Cooking increases the energy available from starchy foods such as potatoes and grains and inactivates certain food toxins, thereby increasing the range of foods available to us. Whether such foods belong in an optimal diet remains to be established. The longest-living population in the world, the Japanese Okinawans, make extensive use of cooked grains, sweet potatoes, vegetables and soy products and little use of raw fruit. However, there is no large group of long-term raw food vegans to provide a direct comparison. There is good direct evidence that large amounts of refined grains are associated with increased risk of heart disease and diabetes in Western populations. However, higher consumption of whole grains is associated with reduced risk of heart disease and diabetes, so this evidence suggests that grain should be consumed in unrefined (whole) form rather than eliminated altogether, at least for most people.

www. superfoodhealthyliving. com www. superfoodhealthyliving. com Many of David Wolfe’s proposed B12 sources have been directly tested and shown to be inadequate. Nori and spirulina failed to correct deficiency in macrobiotic children and did not maintain adequate blood B12 levels in a Finnish raw food community. Probiotics did not consistently correct low B12 availability in Hallelujah dieters. A UK raw food vegan went B12 deficient while growing his own food and eating it unwashed: based on measured B12 levels in soil this is unsurprising. Other proposed sources have not been tested so directly, but the only two published studies of B12 levels in raw food vegans both showed inadequate B12 levels. Low B12 levels give rise to elevated homocysteine levels with an associated increased risk of many illnesses, including stroke and heart disease, without any classical B12 deficiency symptoms. In children the onset of full-blown deficiency can be very rapid with much greater risk of long-term damage or even death. At least 3 micrograms per day of B12 from fortified foods or supplements is needed to minimise homocysteine levels in adults. Breast milk is an adequate source for infants only if the mother’s intake is adequate. The main argument for the desirability of high raw diets derives from comparison with our evolutionary diet and the diets of our great ape relatives. All the great apes eat diets centred on raw fruit (chimps, bonobos, orangutans, lowland gorillas) or raw leaves . . .

www. superfoodhealthyliving. com www. superfoodhealthyliving. com In selecting fruits, there is no need to rely on unusual or exotic items. Bananas are a good energy food, being relatively low in fibre and high in potassium. Oranges are rich in calcium, folate, potassium and vitamin C. The high potassium and low sodium content of raw vegan diets reduces the need for calcium by reducing calcium losses and can be expected to reduce blood pressure and risk of stroke. The various raw vegan dietary schools differ in their approach to B12. Some recommend that B12 supplements should not be taken unless clear deficiency symptoms occur. David Wolfe (Nature’s First Law) recommends seven different potential B12 sources, including unwashed or wild plants, nori, spirulina, fermented foods or a probiotic, with a B12 supplement as an alternative if these are not available. George Malkmus has recommended regular use of a B12 supplement since a study of Hallelujah dieters showed signs of inadequate B12 in most of them and showed that a B12 supplement or fortified nutritional yeast corrected this reliably while probiotics did not. The confusion in this area arises from a conceptual error. Many raw food or natural hygiene advocates believe that our evolutionary diet and that of our great ape relatives did not include an external source of B12 and then conclude that humans shouldn’t need such a source. In fact, all the other great apes – even the gorillas – consume insects incidentally along . . .

www. superfoodhealthyliving. com www. superfoodhealthyliving. com Getting 30% of calories from green vegetables is probably unrealistic for most people, even with the use of blended salads and juices. For instance, 900 g of lettuce plus 450 g of kale provides just 300 kcal or about 15% of calories. Fortunately, however, such high intakes are unnecessary for nutritional adequacy. Green leafy vegetables and broccoli contain higher levels of zinc, calcium and protein than fruit and are therefore an important part of raw diets, but about 500 g per day of green vegetables, including a mixture of lettuces, broccoli and darker leaves such as kale and spinach, is sufficient to bring mineral and protein intakes into line with general recommendations. Such vegetables also provide vitamin K, which promotes healthy bones. Other raw vegetables can be useful: for instance, carrots are a good source of calcium and peas a good source of zinc and protein. The best balance between sweet fruit and fatty foods is probably a matter of individual constitution. Some people experience dental problems with a very high fruit intake. This can be a particular problem for young children. Many people will struggle to maintain weight if they do not include significant amounts of high fat foods. More than 10% of calories as polyunsaturated fat is not recommended. Olives, avocados, almonds, hazelnuts and macadamias are all dominated by monounsaturated fats, which are the safest fats to consume in large . . .

www. superfoodhealthyliving. com www. superfoodhealthyliving. com A raw food vegan diet may be defined in various ways, but usually entails at least 80% by weight being raw plants. Many people report feeling healthier and more energetic on adopting such diets, but there are too few long-term raw food vegans for direct evaluation of the success of raw vegan diets versus other diets. We can, however, evaluate such diets against known human nutritional requirements to gain a better understanding of the ways in which appropriate raw vegan diets could benefit health. www. vegansociety. com Raw vegan diets comprise three key food groups: sweet fruit, high-fat plants and green leafy vegetables. Raw food authorities differ in the proportions recommended, some suggesting that 2% of calories from green leafy vegetables (about 300 g of lettuce per day) is sufficient while others recommend that about 30% of calories should come from green vegetables. Similarly, recommendations on high fat foods such as avocados, olives, nuts, seeds and cold-pressed oils range from a few percent to about 40% of calories. The Hallelujah diet founded by George Malkmus puts particular emphasis on carrot juice and barley grass, which contribute about 15% of calories.
