If you are into your 60s and 70s, it would be a good idea to take a digestive enzyme pill with your primary meal, as these enzymes decrease with old age, so that without a supplement, you are getting much less value from the food that you eat because it doesn’t get thoroughly digested for lack of digestive enzymes.
Yet another problem with old age and digestion is that the hydrochloric acid produced by the stomach to breakdown food decreases with old age, so that food — and proteins in particular, which are more complex compounds — don’t get broken down as efficiently by digestion in the stomach for lack of this acid, which is another reason why the old should increase the amount of protein in their diet somewhat to compensate for this inefficient digestion. A sprinkle of lemon juice on your salad would help here with digestion in the stomach.
