Raw Vegan Diet Promises Lightweight, Healthy Bones
http://www.medindia.net/news/view_news_main.asp?x=7340

Researchers from Washington University School of Medicine identify yet another reason to indulge in a vegetarian diet. Yes! Uncooked vegetarian food has been found to play a critical role in the development of lightweight, yet healthy bones. Surprisingly, individuals consuming such a diet have been found to have a low bone mass.

The study was conducted among a group of 18 individuals aged between 33 and 85 years, under a strict vegan diet, devoid of any animal product. The diet had however, an abundant supply of uncooked fruits, vegetables, sprouts, nuts, seeds and legumes in a dash of olive oil. All the study participants had been consuming the above diet for an average of 3.6 years.

The diet pattern and the health effects of this group were compared to those who ate a traditional American diet consisting of cooked food, animal products and refined carbohydrates. Care was taken to ensure that the control group was matched to the experimental group on the basis of age, sex and socioeconomic status.

Upon analysis of the obtained data, several important findings were uncovered. First, those who had been consuming raw food were found to have significantly lower body mass indices. Secondly, the bone mass in the hip and lumbar spine region was much lower compared to the control group. This meant an increased risk for fracture and osteoporosis.

Turning on to the other side, the experimental group was found to have lower levels of inflammation, as revealed by reduced levels of C-reactive protein. Inflammatory response triggers the production of this protein by the liver. In addition, lower levels of Insulin-like growth factor-1 (IGF-1) were also found. Increased levels of this protein have been linked to an increased risk for prostate and breast cancer. Vitamin D levels of those under the vegan diet were much higher.

Based on the above finding, the researchers have arrived at few important conclusions. People who consume raw food have a low body fat, lighter bones, higher levels of Vitamin D and reduced levels of inflammatory markers. The bone turnover, is however normal. In addition, they were more susceptible to osteoporosis and osteopenia (severe bone loss), which is clinically insignificant.

This observation in the raw food vegans is marked contrast to that observed in menopausal women who have reduced bone mass, increased fracture, osteoporosis risk and high levels of inflammatory markers in their blood (cytokines). More studies are clearly indicated to better understand the risk-benefit ratio associated with a raw vegan diet.

Healthy eating, sea to sky

For many of us, winter heralds the pleasure of travel. For some, it is the best season to visit exotic locations and escape from the cold and rain. For others, it’s an opportunity to reconnect with distant family members. Work-related projects recently took me to California and Barcelona, Spain, and this month’s column was inspired by KLM’s strict vegetarian meal, served on my return flight via Amsterdam.
My dinner consisted of roasted eggplant in a delicious sauce, couscous with currants and coriander, a diced beet salad with endive, and fresh fruit slices (pineapple, grapefruit, and kiwi) with a fruit sauce for dessert. Not bad for an airline.
Whether you are a vegetarian, vegan, or raw food enthusiast, or you have food sensitivities, or you simply want to enjoy healthy meals during your travels, a little pre-planning will help you meet your food requirements, wherever you go. Here are some pointers:
1. Specify food preferences in advance
Pack your own healthy lunch for short flights; on longer flights, most airlines offer a meal service that caters to special needs. You can request several types of vegetarian diets and order an appropriate meal for your food sensitivities. Whether you are travelling by train, plane, or cruise ship, discuss food restrictions when you book your journey. You will often be pleasantly surprised at how well these companies take care of you.
2. Research the internet
Conduct some internet research to find food establishments along your travel route and at your destination. Vegetarian restaurants typically serve meals that are free of fish, dairy, eggs, animal products, and gluten-free grains. These establishments can accommodate a wide variety of health conditions, including diabetes, heart conditions, and other chronic diseases. Visit www.vegdining.com, www.happycow.com, and www.ivu.org, and also check out some sites related to food allergies.
Before you arrive you may wish to contact restaurants , via phone or email, to explain your limitations and to ask whether they are equipped to accommodate your needs.
3. Check out the food guides
The Vegetarian Journal’s Guide to Natural Food Restaurants in the U.S. and Canada is handy during road trips (www.vrg.org). For information about vegetarian restaurants in Europe, visit www.vegetarianguides.co.uk. Our books, Becoming Vegetarian, Becoming Vegan, and Raising Vegetarian Children all include travel sections, as does the Food Allergy Survival Guide. (Available at Banyen, Chapters, and Amazon.com.)
4. Pack some containers
It can be immensely helpful to purchase a few spill-proof containers in suitable sizes for a serving of vegetable or bean salad, hummus, salad dressing, nut butters, or a non-dairy beverage to round out the foods available enroute. You may want to bring a plastic fork and spoon. (To my amusement, in the wake of increased airline security since 9/11, I once had my small, plastic fork confiscated before boarding a Hawaiian airliner, after which the airline supplied me with an identical plastic fork for its in-flight snack.)
Certain foods pack well for travel. Combine your favourite nuts and dried fruits to create a nourishing, and even exotic, trail mix. Bring small packages of non-dairy milk, although cereals, granola, and muesli also taste good with fruit juice. You’ll find delicious, fresh juices in airports throughout Europe and even in the departures area of our own Vancouver airport. For a protein boost, reconstitute individual portions of instant soup mix (black bean, lentil, or curry) with hot water. Mix ready-to-eat tofu with a little seasoning and chopped, raw veggies to make a dip or sandwich filling. When food foraging is challenging, add a multivitamin mineral supplement.
5. Plan your exercise program
Fitness profoundly affects how we feel, so it’s wise to include it in your plans. When I travel as a speaker or am visiting, I advise my hosts that I prefer to include an hour of exercise every day; I inquire about the proximity of beautiful parks, swimming pools, and recreational facilities. Fitness becomes a rich and integral part of our itinerary. In Barcelona, in addition to visiting a Gaudi park, we toured an interactive playground with an immense xylophone that allowed children and adults to leap from note to note, teeter-totters that triggered fountain sprays, and unique merry-go-rounds.
Travel in good health and bon voyage.
