RIO - Seguir uma dieta vegetariana pode ser uma boa maneira de diminuir o risco de doenças crônicas como diabetes, obesidade, hipertensão e câncer, afirma a Associação Dietética Americana (ADA), que publicou esta semana uma atualização de suas recomendações sobre alimentação saudável no "Journal of the American Dietetic Association". Segundo os nutricionistas da ADA, não há dúvidas de que uma dieta vegetariana bem planejada é uma opção saudável para crianças, adolescentes e adultos.

"A Associação Dietética Americana reconhece que uma dieta vegetariana bem planejada, incluindo o vegetarianismo completo (que exclui todo tipo de carne e ovos) e o veganismo (que exclui carnes, ovos e laticínios), pode ser saudável, nutricionalmente completa e traz benefícios na prevenção e no tratamento de certas doenças. As dietas vegetarianas são eficazes em todas as fases da vida, incluindo na gravidez, na lactação, na primeira infância, na adolescência e para atletas", divulgaram em nota os nutricionistas Winston Craig e Reed Mangels, conselheiros da ADA.

Os nutricionistas aproveitaram para enfatizar o bom resultado de inúmeros estudos que ligam uma dieta com menos carne a um risco menor de uma série de doenças. Quem é vegetariano ou exclui a carne do cardápio alguns dias da semana tem menos colesterol alto, problemas cardiovasculares, hipertensão e diabetes tipo 2, afirmaram Craig e Reed. 

Quem segue este tipo de dieta também tende a comer menos gorduras saturadas e mais fibras.

CHICAGO – The American Dietetic Association has released an updated position paper on vegetarian diets that concludes such diets, if well-planned, are healthful and nutritious for adults, infants, children and adolescents and can help prevent and treat chronic diseases including heart disease, cancer, obesity and diabetes.

ADA’s position, published in the July issue of the Journal of the American Dietetic Association, represents the Association’s official stance on vegetarian diets:

It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life-cycle including pregnancy, lactation, infancy, childhood and adolescence and for athletes.

ADA’s position and accompanying paper were written by Winston Craig, PhD, MPH, RD, professor and chair of the department of nutrition and wellness at Andrews University; and Reed Mangels, PhD, RD, nutrition advisor at the Vegetarian Resource Group, Baltimore, Md.

The revised position paper incorporates new topics and additional information on key nutrients for vegetarians, vegetarian diets in the life cycle and the use of vegetarian diets in prevention and treatment of chronic diseases. “Vegetarian diets are appropriate for all stages of the life cycle,� according to ADA’s position. “There are many reasons for the rising interest in vegetarian diets. The number of vegetarians in the United States is expected to increase over the next decade.�

Vegetarian diets are often associated with health advantages including lower blood cholesterol levels, lower risk of heart disease, lower blood pressure levels and lower risk of hypertension and type 2 diabetes, according to ADA’s position. “Vegetarians tend to have a lower body mass index and lower overall cancer rates. Vegetarian diets tend to be lower in saturated fat and cholesterol and have higher levels of dietary fiber, magnesium and potassium, vitamins C and E, folate, carotenoids, flavonoids and other phytochemicals. These nutritional differences may explain some of the health advantages of those following a varied, balanced vegetarian diet.�

The position paper draws on results from ADA’s evidence analysis process and information from the ADA Evidence Analysis Library to show vegetarian diets can be nutritionally adequate in pregnancy and result in positive maternal and infant health outcomes. Additionally, an evidence-based review showed a vegetarian diet is associated with a lower risk of death from ischemic heart disease.

A section in ADA’s paper on vegetarian diets and cancer has been significantly expanded to provide details on cancer-protective factors in vegetarian diets. An expanded section on osteoporosis includes roles of fruits, vegetables, soy products, protein, calcium, vitamins D and K and potassium in bone health. “Registered dietitians can provide information about key nutrients, modify vegetarian diets to meet the needs of those with dietary restrictions due to disease or allergies and supply guidelines to meet needs of clients in different areas of the life cycle,� the authors said.

The American Dietetic Association is the world’s largest organization of food and nutrition professionals. ADA is committed to improving the nation’s health and advancing the profession of dietetics through research, education and advocacy. Visit the American Dietetic Association at www.eatright.org.
