Vegetarian Diets

In recent times, there have been many scientific evidences which suggest that wholesome vegetarian diets offer significant advantages compared to diets containing meat and other foods of animal origin. The benefits ranges from lower intakes of cholesterol, saturated fats, animal proteins and higher intakes of dietary fiber, vitamin C and E, carotenoids, magnesium, folic acid,  and other phytochemicals. However, it is often said that vegetarian diet lacks the nutrients like vitamin B12, proteins, zinc, calcium etc., but if an “Appropriate diet with proper planning” involving supplements is consumed, these deficiencies will never exist. Through the present editorial, I would like to show few benefits of having a vegetarian meal.

Acid Detergent Fibre

Insects serve as a major source of nutrients for many animal species, but complete nutritional information of wild insects is lacking. Wild pallid-winged grasshoppers, rhinoceros beetles and white-lined sphinx moths were caught in Rio Verde, Arizona, in the summer of 2013 (grasshoppers and beetle) or the spring of 2015 (moths). Pallid-winged grasshoppers, rhinoceros beetles and white-lined sphinx moths were analysed for moisture, crude protein, fat, ash, acid detergent fibre, minerals, amino acids, fatty acids and vitamins and values compared the nutrient requirements for both rats and poultry as reported by the National Research Council (NRC). The acid detergent fibre was also analysed for nitrogen. When compared to the nutrient requirements as established by the NRC for growing rats, grasshoppers were deficient in calcium, vitamin A, vitamin D, thiamine and vitamin B12, beetles were deficient in calcium, vitamin A, vitamin E, thiamine, pyridoxine and linoleic acid and moths were deficient in calcium, sodium, vitamin A, vitamin D, pyridoxine and vitamin B12. In contrast when compared to the nutrient requirements as established by the NRC for growing broiler chickens, grasshoppers were only deficient in calcium, manganese, and vitamin A, beetles were deficient in calcium, manganese, vitamin A, vitamin E, thiamine and linoleic acid and moths were deficient in calcium, sodium, manganese, vitamin A, vitamin D, and linoleic acid. These data show that Pallid-winged grasshoppers, Rhinoceros beetles and White-lined sphinx moths were good sources of most known nutrients including all essential amino acids, most minerals and most vitamins.

Vegetarian Diets

There is an increasing number of people who go vegetarian. Some young parents also switch to this diet. The safety of vegetarian diets, especially vegan diets, is very important, especially during pregnancy. Unfortunately, reference publications do not provide coherent data on the safety of vegetarian diets during pregnancy. On the one hand, the vegan diet has advantages because it reduces the risk of heart disease and gestational diabetes. On the other hand, vegetarians/vegans should be aware of potential deficiencies of some nutrients (iron, zinc, vitamin B12, vitamin D, omega-3 fatty acids, calcium, iodine) and the clinical consequences for the fetus. For example, iron deficiency may affect cognitive abilities, behavior, intelligence and increase the risk of preterm birth and low birth weight of infants. Plant food contains non-haem iron with variable absorption. Therefore, the vegan diet should include nutrients increasing the bioavailability of iron, e.g. ascorbic acid, carotene and retinol. Due to the fact that animal food is the main source of vitamin B12, vegans are at a very high risk of vitamin B12 deficiency, which will affect the infant’s weight at birth. Low level of vitamin D, which is prevalent in animal food, is the most common deficiency among vegans and lacto-ovo vegetarians. This vitamin prevents gestational diabetes, reduces insulin resistance and guarantees normal function of the musculoskeletal system. Zinc deficiency during pregnancy may lead to preterm birth, neural tube defects or even miscarriage. In view of the clinical consequences of potential deficiencies of nutrients, the vegetarian/vegan diet should be well balanced.

Abstract In Western countries, vegetarian diets are associated with lower intakes of energy, saturated fatty acids and animal protein and higher intakes of fibre and phytochemicals, compared to omnivorous diets. Whether the corresponding health benefits in vegetarians outweigh the risks of nutrient deficiencies has not been fully clarified. It should be noted that vegetarians often have a higher socioeconomic status, follow a more health-conscious lifestyle with higher physical activity, and refrain from smoking more often than non-vegetarians. The nutritional needs of growing children and adolescents can generally be met through a balanced, vegetable-based diet; however, due to their higher nutrient requirements per kilogramme of body weight, vegetarian children have a higher risk for developing nutrient deficiencies than adults. With a vegetarian diet, the mean intakes of some nutrients, such as the omega-3 fatty acid docosahexaenoic acid (DHA), are lower than in omnivores or those eating fish. For other nutrients, such as iron and zinc, the bioavailability from vegetable foodstuffs is reduced when the intake of phytates and fibre is high; thus, the prevalence of iron deficiency can be increased despite high vitamin C intake. In addition, vitamin B12 is only found in animal-source foods. Vitamin B12 should be supplemented in people of all age groups who follow a strict vegan diet without consuming animal products. A vegetarian diet in childhood and adolescence requires good information and supervision by a paediatrician, if necessary, in cooperation with an appropriately trained dietary specialist.

The rumen degradability and postruminal digestion of rumen escape dry matter (DM), nitrogen (N) and metabolically essential amino acids (EAA) for canola meal (CM) from five different processing plants (samples 1–5) and one sample of soybean meal (SBM) were compared. Rumen degradability was estimated by incubating sample-filled small nylon bags in situ in the rumen of steers for 0, 4, 8, 12, 16 and 30 h. Postruminal digestion was estimated using a sequence of ruminal in situ incubations for 0, 4, 8, 12 and 16 h, in vitro incubation in an acid-pepsin solution and a mobile nylon bag technique distal to the abomasum. The rumen escape of nutrients for CM1 was consistently lower compared to other CM samples, while CM4 resulted in the highest escape of nutrients at 30 h. An estimate of maximum degradability of EAA measured at 30 h differed among CM samples, with the rumen escape of EAA being CM4 > CM2 = CM5 ≥ CM1 = CM3 > SBM. The DM, N and EAA content of mobile bag residues was relatively uniform among CM samples, particularly after 12 and 16 h of ruminal fermentation, but was higher for CM than for SBM, probably due to a low digestibility of CM hulls. The rumen degradability of CM from different processing plants differed and as a consequence the postruminal digestion of nutrients in CM differed.
