Dear Ayesha,Older persons are particularly vulnerable to malnutrition. Moreover, attempts to provide them with adequate nutrition encounter many practical problems.So,many people now consider eating organic foods rather than their conventional non-organic products. Organically grown foods are without pesticides, fertilizers and other synthetic additives. People often choose to switch to organic products because they believe it is a healthier and tastier option.Maintaining a healthy and balanced diet can improve the health.For old age people fresh and natural food has been shown to be better and healthier option than processed food. Impact of physical activity, assessment of the nutritional status of older person is also very important.So, try switch to organic for healthy lifestyle.Hope this satisfies your query.
