It takes too many clicks to enter data!

When entering a food item you first have to scan or search for it, then you choose number of units and then the unit type (if you are not so lucky that the person who entered this particular food item in the first place is or could have been yourself). Example: When I scan my favorite food, the default is 1 unit of 100 ml. Then I have to enter the number of grams I want, and then try to find grams in the abundance of units (10) which has been entered (alas, no grams), then choose ml and move on. Every. Single. Time.

With user defined defaults for values and unit type, this would be scan and enter. This should be a piece of cake (300 kcal/100g) to implement!
