April 17, 2017

Glycine max, commonly known as soybean or soya bean, is part of the legume family, and native to East Asia. It is grown for its edible bean which has high levels of protein and has a wide variety of uses. Soybeans have only been introduced to the Western world since the 20th century, and are a relatively easy to grow and hardy plant, due to their adaptation to a variety of soils and climates. The most common type of soybean is a yellow colour, but rarer varieties can come in black, brown, or green colours. Some uses for this bean include: animal feed (defatted soybean meal), meat and dairy substitutes, industrial products such as lubricants, plastics, and waxes, and the production of foods such as soy vegetable oil, soy milk, tofu, tofu skin, soy sauce, fermented bean paste, natto, and tempeh.

SEASONAL AFFECTIVE DISORDER (SAD)

Seasonal Affective Disorder is a type of depression that is related to seasonal changes. This condition is also known as: winter depression, winter blues, summer depression, or seasonal depression. To be correctly diagnosed, the affected person should be known to have normal mental health throughout the rest of the year, with periods of depression occurring at the same time each year, usually winter. It is caused by the variation of light exposure in different seasons, most commonly, lack of light in winter. The lack of sunlight decreases the chemical serotonin (which regulates mood), and increases the production of the chemical melatonin (increases sleep and drowsiness). Cases of SAD are rare in Australia and are more likely to occur in places further from the equator where the days are shorter.

Symptoms include:

  • Lethargy
  • Oversleeping
  • Poor sleep
  • Difficulty getting up in the morning
  • Insomnia
  • Decreased libido
  • Body aches
  • Overeating
  • Weight gain
  • Sadness
  • Moodiness
  • Anger
  • Emptiness
  • Loss of interest in usual activities
  • Cravings for carbohydrates
  • Inability to concentrate
  • Restlessness and irritability
