The boiling temperature of nitrogen is â195.8 Â°C (â320.4 Â°F), about 13 Â°C (â23 Â°F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen.
Acidic foods like citrus fruits can stimulate acid production and increase heartburn. Avoid oranges, grapefruit, lemons and their juice. Like citrus fruits, tomatoes and products made from tomatoes (tomato sauce and paste, tomato juice) can stimulate the stomach to produce more acid.
Tomatoes are rich in lycopene, which helps reduce inflammation in the lungs and throughout the rest of the body. Cooked tomatoes provide even more lycopene than raw ones, so tomato sauce works, tooâand a 2013 Iranian study found that tomato juice consumption was also beneficial for reducing systemic inflammation.
