Nutrition plays a pivotal role in the ageing population to fuel their natural ageing process. All over the world, people are living longer, and healthy ageing is a priority for the public health sector. As ageing is the natural trait of human beings, healthy ageing is the disease-free natural ageing process. 

In most cases, ageing brings along deadly and chronic non-communicable diseases, making old age a burden for the elderly. In addition, the financial and social obligations have levied enormous stress on older adults, which are solely responsible for various age-related problems. 

Common Diseases Associated with Ageing

The most common diseases like cardiovascular diseases, diabetes, cancer, and neurodegenerative diseases collectively contribute to 70% of global mortality.

There are several factors responsible for the complex process of healthy ageing. The factors responsible for healthy ageing are diets and eating habits, genetic receptiveness, and various environmental and behavioural factors.

The habit of overeating, following unhealthy diets and sedentary behaviour, and cigarette smoking increase the chances of obesity, hypertension, modified lipid metabolism, and diabetes.

Research has revealed that healthy ageing is a multidimensional phenomenon that is not regulated by one single nutrient but by a combination of foods and lifestyles together.

Vegetarian Green Diet and Healthy Ageing

According to research conducted in 2020, over 700 million people worldwide are above the age of 65, which is increasing yearly. In Hong Kong, life expectancy is high, and experts believe that the proportion of the elderly population will reach up to 38% in 2069 from 18% in 2019. 

In the intervening period, there is a lot of focus on the dietary regime. It includes less amount of fruits and whole grains with higher sodium intake.

On the other hand, the emphasis on prudent and occident influenced dietary patterns consists of a fair amount of protein and refined grains. The availability of these high-quality foods for almost everyone hinders following healthy nutritional habits.

The Green Diet

Individuals who live on plant-based foods without any animal meat consume less salt. The rapid acceptance of a “green diet” based on plant-based foods without excessive sodium and non-animal proteins also helps reduce food waste. It is significant in maintaining a green environment which is a prominent factor in healthy ageing. 

Individuals are developing cautious mindsets against excessive and unnecessary purchases of food items. The association of red meat in the diet is often the reason behind colorectal cancer and diabetes. 

The Practice of Green Diet and Its Importance

The practice of a green diet is of paramount importance for healthy ageing. Research conducted by the Centre for Health Protection (2015) revealed that people above 15 consume one processed food daily. Even people keep less than five portions of fruits and vegetables in their daily dietary regime. This dietary pattern reflects that people are more prone to foods containing excess sodium, fat, and calories than nutrients. 

The nuts and seeds provide essential amino acids in our bodies while satisfying our daily protein intake of 10%-15% of our body mass. In addition, fruits and vegetables can be a great source of dietary fibre. Doctors recommend consuming at least 25 grams of dietary fibre daily as an adult or adolescent. 

A green diet emphasises the consumption of leafy vegetables and olive oil to reduce the scope of cardiovascular diseases and arterial stiffness. Vegetables and fruits are also full of antioxidants that help prevent chronic diseases. It is necessary to eliminate the free radicals and reduce cancer risk. Every increased consumption of vegetables can reduce the chances of cancer by 15%, cardiovascular disease by 30%, and mortality by 20%. 

Benefits of Adding Fruits and Vegetables to Our Diet

Fruits and vegetables are good sources of antioxidants that help promote healthy ageing. It prohibits the chances of chronic diseases and takes care of skin ageing too.

Here are some instances:

  1. Tomatoes contain antioxidants like beta-carotene, lycopene, potassium, folate, vitamin C, flavonoids, and phenolics. However, if fried or cooked, it loses its nutrients.
  2. Green leafy vegetables contain vitamins A, B, and C, phenolic and ascorbic acids. As a result, it maintains healthy skin and prevents cancer. 
  3. Potato contains ascorbic acids, especially in marble variety of potatoes is rich in ascorbic acids. However, the level decreases due to storage, processing, and cooking. 
  4. Cruciferous Vegetables: Vegetables like cabbage, broccoli, and Brussel sprouts are rich in polyphenols, flavonoids and glucosinolates. Hydrolysis products of these vegetables contain antioxidant, antibacterial and anti-cancer elements. 
  5. Chilli and Sweet Pepper contains Vitamin A, C, and E and is also neutral and acidic phenolic acid. Carotenoids are present in the mature stages of pepper, but the level of lutein declines eventually with maturation. 
  6. Bulb and Root Crops: Leaves and stems of these vegetables, like garlic and radish, are enriched with antioxidants like syringic acids, vanillic acids, ferulic acids, and sinapic acids. Carrots especially contain carotenoids, vitamins C and E, and phenolics. 
  7. Leguminous Vegetables: These vegetables are filled with phenols, phytate, and Vitamin C. while snow peas contain beta carotene and ascorbic acid along with phenol and Vitamin C. 
  8. Drumstick: This tree’s mature and tender leaves are potent antioxidants that prevent oxidative damage to biomolecules and our bodies. 
  9. Citrus Fruits: Most fruits are packed with antioxidants and have many health benefits. Fruits like peach, raspberry, strawberry, cranberry, red grapes, red currants, figs, cherry, pears, guava, orange, mango, apricots, cantaloupe, papaya, watermelon, and tomatoes are rich in various antioxidants. 

According to research, there is a balance between our bodies’ oxidants, antioxidants, and biomolecules. The oxygen-derived free radicals, responsible for the ageing process, cause damage to our tissues and cells.

The antioxidant prevents those free radicals from damaging our tissues and cells. Therefore, our skin remains healthy and supple. Antioxidants are essential to prevent premature ageing. We can consume vegetables and fruits to gain antioxidants and protect our bodies from cell and tissue damage. Hence, in the case of healthy ageing, antioxidants are a must.

Obtaining healthy ageing is a process of keeping the body fit and feeding our body with easily digestible, nutritious foods. Old age or ageing is not a disease. It is a biological process obtained by every human being. The way it can be made seamless, painless, and disease-free is our goal.

A healthy diet, especially the green diet, is suitable for people of every age if they are not allergic to any of the ingredients mentioned. The ageing process might be complex but attaining healthy ageing is not that hard. It is a process through which the eating habits, lifestyle, and perceptions of our life change and reach an optimum state.

Not only food habits but also little freehand exercises are good for health. Staying active in old age will help you stay healthy. However, being active does not necessarily mean indulging in strenuous activities. Hence, everybody can make their life healthy through a few changes in their outlook and habits.
