Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of water channels or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
Sulfates & Additives. Sulfates added into processed foods and occurring naturally have been shown to trigger asthma attacks. These can be found in lemon juice, processed potatoes, dried fruits and vegetables and pickled foods.
Some foods, colourings and preservatives may trigger asthma symptoms or make them worse. Some people may also experience hives, rash, nausea, vomiting and diarrhoea. It may help to keep a food diary to track what's causing allergic or asthma reactions. Talk to your doctor if you have concerns.
