Below examples:
1. Cucumber and tomato or paprika- enzyme ascorbinase contained in cucumber oxidizes vitamin C in tomato or paprika. This connection is popular used in salads. It’s not problem, only if we eat lots of different products rich in vitamin C.
2. Cottage cheese and tomato- it seems like great combination for breakfast, but truth is different. Acids contained in tomato as: citric, malic, coumaric connect with calcium from cottage cheese. After longer term diet will arise crystals which will accumulate in joints giving pain.
3. Tea and yeast-cake- cake is rich in vitamin B1 and lots of minerals; tannins from tea act on gastrointestinal mucosa and impedes absorption these substances and damages vitamin B1, so better to choose another drink or prepare very weak extract of tea.
4. Cheese and meat- phosphor contained in cheese impedes absorption of zinc from meat.
5. Mushrooms and alcohol- proteins from mushrooms will not be digested.
6. Red meat and tea, coffee or vine- limited absorption of iron, vitamins B and magnesium. Red meat is richest in iron, has much more best absorbed iron than spinach. After dinner better to wait 1h and than drink tea, vine or coffee.
