Prevalence of vitamin B12 deficient Korean centenarians on the traditional semi-vegetarian was not higher compared with those from Western nations with animal-oriented foods. Screening of vitamin B12 contents has revealed that some traditional soybean-fermented foods, such as Doenjang and Chunggukjang, also Gochujang, Ganjang (soy sauce), cabbage Kimchi, and seaweeds (laver , sea lettuce, sea tangle, sea mustard ) contain considerable amounts of vitamin B12. Soybeans (steamed) and tofu do not contain B12.
Laver, dried, seasoned & toasted - 55 -71 mcg in 100 g dry weight
Sea lettuce, raw - 85 mcg in 100 g dry weight
Lifestyle - interests, opinions, and behavioural orientations of an individual, group, or culture.
Personal lifestyle typically reflects individual attitudes, way of life, values, world view, and personal identity. Not all aspects of a lifestyle are voluntary. Surrounding social and technical systems can constrain the lifestyle choices available to the individual. Location is important factor of lifestyle. The nature of the neighborhood in which a person resides affects the set of lifestyles available to that person due to differences in degrees of affluence and proximity to natural and cultural environments.
Lifestyle may include views on politics, religion, health, and intimacy.
For example, "green lifestyle" means holding beliefs and engaging in activities that consume fewer resources and produce less harmful waste, and deriving a sense of self from holding these beliefs and engaging in these activities.
