I doubt rent and food can go up much because of UBI as the basic versions of both seems more controlled by supply than demand. For areas where demand is higher than supply I do suspect that thing will get magically get more expensive in order to class distinguish between poor people under UBI and rich people.
Utilized farm land and output per farmer has steadily gone up each year with basic food prices falling as an result. I guess I could imagine that if more people would want to become farmers because of UBI it could lead to farm land becoming more expensive which in turn would lead towards higher food prices. UBI will likely also increase prices for status food where there is a low supply and high demand, so I would expect a rise in cost for food that get associated with wealth and status.
For rent it is more complicated. Low income jobs tend to force people to live in cities that are near industries. UBI would allow said people to live outside cities which tend to have significant lower rent as there is significant more supply of cheap houses and cheap land to build cheap houses. Being poor however tend to have a behavior impact where people want to live close to relatives, which in turn often has the result of people staying in cities even if they have cheaper living elsewhere. It is a possible risk with UBI that in cities the rent will go up a bit in low income areas, and significant in high income areas in order to keep people with UBI from living there.
