Thanks for contacting with your health concern and at her age [70 years] initially some physiological factors which have to be kept in mind are:
i. As the age progresses people tend to produce less acid [HCl] called as
hypochlorhydria resulting in impaired/slower digestion. [and veggies are most affected since vegetarian diet are low in protein which can result in decreased production of HCl]
ii.
Lactose intolerance.
iii.
vitamin B12 deficiency [intrinsic factor] level also decrease as the age progress and thus they are more prone to atrophic gastritis
2. So it is best to put her on a dietary regime which is free from causing stomach upset/burping, like
- Lactose-free product like soy milk, lactose-free milk, potato, rice, barley, margarine without butter/milk, fruit and vegetable juice, plain herbs and spice, jellies, jams
- maintain a diet with low glycemic index/low fat.
- eat smaller meals regularly and chew food thoroughly.
- take a
multivitamin which includes B3 and B12.
. increase intake of fiber and omega 3 fatty acids
PS. check with her vitamin B12 level
