* Produce 5 kids in the first place.
* Take care of the kids that they were able to produce, making survival of even half them much less likely.
But in actuality, best we are able to determine hunter-gathers who made it into adulthood lived longer, healthier lives than those in agrarian lifestyles.

H-G societies tend to be smaller groups where everyone in the village helps with childcare, so if a parent was out of action for a while the children could still be gathered.
This is covered in the book Hunt, Gather, Parent by Michaeleen Doucleff, specifically with the Hadzabe people (Tanzania).
The adults getting sick and being undernourished was one of the leading causes of infant mortality.
They were getting sick and died more often than us, but still enough survived to keep the population alive. There's no contradiction.
I admit they probably had a stronger immunologic system on average, by virtue of relying on it and "exercising" more often. Alternatively, people prone to getting sick just died early.
