Condensed milk has 3.2 kcal = 13 kJ/g, 13 MJ/kg. To lift 1 kg 1 km under Earth gravity takes 10 kJ. So enough energy to lift the milk through a 1,300 km long straw. Allowing for human muscle and digestive inefficiencies and friction in the straw that might reduce to 130 km. Of course you can't lift a liquid more than 10 metres by suction in 1 bar atmospheric pressure.
This reminds me of the Pringle calculation: one Pringle contains 40 kJ, if you use about 100 J per metre walked on flat ground, you'd theoretically need to put your Pringles 400m apart to burn one Pringle's worth of energy. Allowing for muscle inefficiencies etc and background metabolism you could probably survive indefinitely, if not healthily, on one Pringle every 40 metres. A lot further for tins of condensed milk though.
