Consumption usually appears as a singular collective to mean generally to use a resource and especially to ingest food. The plural consumptions is found but is quite rare, its uses far less than 1% of the singular form consumption, even taking into account that the latter is an old-fashioned name for tuberculosis. The plural occurs in two settings, the first when the things consumed are disparate.
From Energy Pricing in India by H Sarkar and G K Kadekodi (1988):
Second, while primary energy consumptions (consisting of solid fuels, oil, gas, nuclear and hydropowers) have increased both on per capita and GNP basis, the non-commercial energy consumptions (consisting of firewood, agricultural waste, animal dung etc.) declined between the same period.
The second, when the consumers are distinct:
From Wild Otters: Predation and Populations by H Kruuk (1995):
Wayre (1979) weighed the food for two captives [otters] over 1 week, and found daily consumptions of 12.2 and 12.8 per cent of body weight.
The plural is also employed to distinguish between what is being consumed and who is doing consuming. From Opinions and Decisions of the Railroad Commission of Wisconsin (1980):
The application of the proposed lighting schedules to the 1924 consumptions of lighting customers indicates that these schedules will produce about 10 per cent more total revenues than the schedules now in effect.
The singular could lead to the interpretation that it was lighting customers who were being used every day to produce the lighting.
You'll have to decide for yourself whether beef, lamb, and fish are sufficiently different as foodstuffs to warrant the plural or whether they are sufficiently alike as comestibles to stick with the singular.
