Thing is most apes are obligate herbivores (orangutans, gorillas) and those that aren't, such as chimps and bonobos, suffer from many CVD issues (in fact captive chimps commonly live longer when given zoo based diets). As for obligate carnivore predators the meaning behind what I posted is that they have evolved to not suffer from their main food sources compared to us as omnivores (or more likely originally herbivore derived ancestry) that try to juggle diets that we likely aren't fully meant to have (or least aren't meant to eat 100% of the time like insane carnists would claim). Note also that animals living in captivity have the benefit of many external stressors removed from them which greatly increases their lifespan and leading to suffering from diseases such as cancer (which increase in risk with aging).
