What the right foods for people over 90 years old?

Light food like porridges, cornflakes, light snacks, sandwitches are best recommended for old people over 90yrs. Their digestive system is very weak at this age and having light food makes it easy for digestion. But you cannot compel old people to have light food. Some old people have regular food just like any other individual of all ages, while some others would prefer to have a light diet.
