Introduction
Nutritional needs change throughout life. As people get older, they may need less of some nutrients, such as iron and grains, and need more of others, like calcium and healthy fats, mainly to accommodate constantly changing hormone levels and metabolism. Including nutrient-rich foods in the diet can help get the vitamins, minerals, protein, carbohydrates, and fats needed in old age. A healthy meal plan can help prevent or manage various medical conditions that are often seen in older people, such as heart disease, diabetes, osteoporosis, etc.
What Role Does Nutrition Play in Healthy Aging?
A person's eating habits throughout life can have an impact on their health in old age. A balanced and varied diet full of nutritious food like fruits and vegetables, whole grains, legumes, nuts, lean protein, limited sugar, salt, saturated or solid fats, and alcoholic beverages is critical for good health. A healthy diet can help an older in the following ways-
-
Maintain a healthy weight.
-
Lower blood pressure.
-
Control blood sugar levels.
-
Manage arthritis.
-
Reduce the risk of cancer.
-
Reduces the risk of cardiovascular diseases.
-
Prevent and slow the progression of eye diseases.
-
Keep bones and muscles strong.
-
Help maintain brain health.
How Can Diet Plans Change With Increasing Age?
Age 50 to 70 (women)-
-
Boost the Dairy Intake- The average age for women to hit menopause is 51 years. At this time, the levels of the hormone estrogen begin to fall, resulting in increased bone loss and further leading to osteoporosis. As a result, women’s dairy intake needs almost doubles this time to ensure sufficient calcium. Hence the dairy intake should increase from two and a half serving to four serving after menopause.
-
Pick the Protein- After menopause, the need to replace iron lost through menstruation decreases. Iron intake can range from two to two and a half serving a day. It is recommended to replace red meat protein sources with fish and dairy. Fish consists of omega-3 fatty acids that are good for heart health, and dairy provides good bone health. After the age of 50 years, the recommended serving of grains and cereals should be four servings a day. Choosing whole meal grains such as whole meal bread, brown rice, oats, and quinoa is important to maintain a healthy state of the body.
Age 50 to 70 (men)-
-
Decrease the Meal Intake if Needed- Kilojoules of energy needed for men and women decrease with age because the metabolism slows down and activity levels commonly drop. Men, in particular, stick to the same meal size as they did when they were younger. Hence it is advisable to consult a dietitian to get a proper idea of the meal intake sizes.
-
Burn Up Healthy Fats- The risk of heart disease is more prevalent in males, so the use of healthy oils is important for cardiovascular health. It is recommended to replace trans fat found in deep-fried and baked foods, and saturated fat found in butter, meat, and coconut oil with healthy fats found in olive oil, nuts, and avocado.
Age 70 and above (Men and Women)-
-
Fiber Up- Maintaining a healthy bowel function is more challenging during this period as the overall muscles of the body become less efficient. Hence it is important to try and get an adequate amount of fluids, fresh fruits, and fibrous vegetables for healthy bowels.
-
Calcium- In males, the need for calcium also increases after the 70s. Men should increase their calcium intake from two and a half serves to three serves a day after the age of 70.
Age 80 and Above (Men and Women)-
It is important to maintain weight during this age period. Being overweight can cause several problems for people in their 80s as the appetite usually drops due to age and certain medications. The body mass index increase after the age of 65 years. So instead of focusing on weight loss, elderly people should try to maintain a balanced diet.
What Are the Challenges With Aging?
Older adults typically need fewer calories and more calcium, protein, fiber, vitamins, and minerals. There are certain conditions that pose a challenge while maintaining a healthy diet in older adults, such as
-
They are more likely to experience changes in taste, chewing, and swallowing.
-
They have more medical conditions.
-
They take more medications that can impact appetite, require diet changes, or may interact with alcohol.
-
They are frail with decreased mobility and often need help in preparing meals.
-
They also experience a decline in their sense of thirst and face bladder issues.
-
They are more likely to experience social isolation, which can impact their diet.
-
Older individuals have a decreased ability to absorb and use nutrients with age.
Why Is Healthy Eating Important for Older People?
Poor nutrition can lead to a weak immune system and make the person more vulnerable to infections, slower recovery, and wound healing. It also causes unhealthy weight changes and muscle loss. They can lead to frailty, falls, broken bones, disability, loss of independence, and disease complications. It can also lead to nutrition-related diseases and conditions, such as
-
Malnutrition- It is a consequence of non-getting the right nutrition and calories, becoming more common with age. It can impact anyone, including people who are obese or overweight. Malnutrition can lead to weight loss, muscle loss, frailty, falls, infection, and delayed healing of broken bones.
-
Sarcopenia- It is the progressive loss of skeletal muscle mass and functions caused by changes in the body, including our ability to convert protein into muscle. It is a serious condition that causes increased disability, hospitalization, need for long-term care, and even death.
-
Osteoporosis- It causes bones to become weak and brittle, leading to falls and fractures. While it can be caused by diseases and certain medications, it can also result from eating disorders or not getting enough calcium and vitamin D.
What Is a Healthy Meal Plan Advisable for Older People?
The first step is to limit food high in sugar, saturated fats, and sodium, such as highly processed foods, and check food labels to make healthy food choices. If a person chooses to eat highly processed food, it should be limited and in small amounts. An older person can easily divide certain food on their plate in the following ways-
-
One-half of the plate should be vegetables and fruits.
-
One-quarter of the plate should be proteins such as beans, lentils, nuts, seeds, milk, yogurt, cheese, lean, meat, and poultry.
-
One-quarter of the plate should be whole grain.
Conclusion
The food and beverages an individual consumes profoundly affect their health. Older adults should get recommended daily calories to ensure they get enough proteins. It is also important to avoid sodas and sweetened beverages, and alcoholic beverages, drink enough fluids to stay hydrated, and consult a nutritionist for more information.
