~ some current developments and practicals
An apple a day keeps the doctor away, this could be more than just an old wives tale. It has been shown that an antioxidant found in apples significantly reduces the risk of colon cancer.
That ‘nice cup of tea’ could be helping to improve memory. Researchers at Newcastle University found that both black and green teas affect enzymes in the brain associated with memory, although the effect of the green tea was longer lasting.
Fruits and vegetables
A study of 43 fruits and vegetables suggest that their nutritional value has declined in the past 50 years, scientists say. The researchers suggested the decline may result from the fact that farmers have been planting crops designed to improve traits other than nutritional value, such as size. The researchers said the study also raises the possibility that similar declines might have affected other food crops, such as grains. More research is required to check whether this is so, said Donald Davis, the study’s lead author.
Davis and colleagues studied U.S. Department of Agriculture data on garden crops. “Considered as a group, we found that six out of 13 nutrients showed apparently reliable declines between 1950 and 1999.”
These nutrients included protein, calcium, phosphorus, iron, riboflavin and ascorbic acid. The declines, which ranged from 6 percent for protein to 38 percent for riboflavin, raises significant questions about how modern agriculture practices are affecting food crops.
Life experiences vs. material goods
Through a series of surveys and experiments spanning several years, the researcher Van Boven found that people from various walks of life were made happier by investing their income in life experiences than in material goods. “We found that people receive more enduring pleasure and satisfaction from investing in life experiences than material possessions”, said Van Boven.
In a national survey more than 12,000 Americans were asked about purchasing both consumer goods and experiences, and it was found that when asked which made them happier, most respondents chose their experiential investment over their material possession.
