According to nutrition scientist Merja Suominen from the University of Helsinki, attention to diet should vary with age. For younger individuals, excessive protein consumption can be unnecessary, while for older adults, protein intake is often insufficient. She notes that middle age is a crucial time for managing weight, particularly for women who should focus on maintaining muscle strength.

Suominen advocates a balanced diet aligned with nutritional guidelines as the best choice for promoting health. However, she reminds that different life stages warrant particular attention to specific nutritional aspects. For example, preventing cardiovascular diseases should begin early, as these illnesses develop over time. This suggests a proactive approach to dietary habits can have long-term health benefits.

To support heart health and brain function, avoiding saturated fats while incorporating healthy fats, such as oils and margarine, along with a variety of vegetables is essential. Thus, adapting dietary habits accordingly throughout life can be advantageous in sustaining overall health, as emphasized by Suominen's findings.
