Based on available biochemical, clinical and epidemiological studies, the current US recommended daily allowance (RDA) for ascorbic acid ranges between 75 - 120 mg per day, to achieve cellular saturation and optimum risk reduction of heart diseases, stroke and cancer in healthy adults.
- Males - 90 mg a day,
- Females - 75 mg a day,
- Smokers - +35 mg a day (35 mg/day more)
Fresh fruits, vegetables and also synthetic tablets supplement the ascorbic acid requirement of the body. However, stress, smoking, infections and burns deplete the ascorbic acid reserves in the body and demands higher doses of ascorbic acid supplementation.
Ascorbic acid and its derivatives are widely used as preservatives in food industry.
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.
