As we age, maintaining health is important, making small adjustments to your daily food can make a difference. Emerging research underscores the role diet plays in healthy ageing and reducing the risk of chronic diseases. The Alternative Healthy Eating Index (AHEI) is a great way to tick off foods to include. Developed by nutrition experts at the Harvard T.H. Chan School of Public Health, the AHEI offers a wholesome approach to evaluating diet quality, emphasising foods and nutrients linked to lower risks of chronic illnesses.

What is the Alternative Healthy Eating Index (AHEI)?

The AHEI is a scoring system designed to assess how well an individual’s diet aligns with key dietary recommendations associated with reduced chronic disease risk. Unlike the traditional Healthy Eating Index, the AHEI places greater emphasis on the quality of food choices, focusing on components known to influence health outcomes.

The AHEI evaluates dietary intake across several components, assigning scores from 0 to 10 for each, with a maximum total score of 110. Higher scores indicate better adherence to dietary patterns associated with positive health outcomes.

Key Components of the AHEI

The AHEI assesses the following dietary components:

• Vegetables: Aim for at least five servings daily, prioritizing green leafy varieties.
• Fruits: Consume four servings per day, focusing on whole fruits rather than juices for your nutrients.
• Whole Grains: Incorporate five to six servings daily to support cardiovascular and digestive health.
• Nuts and Legumes: Include a daily serving to provide essential nutrients and healthy fats.
• Fish: Add fish to your weekly meals to benefit from omega-3 fatty acids.
• Healthy Fats: Use unsaturated fats like olive or canola oil in place of saturated fats.
• Sugar-Sweetened Beverages and Fruit Juice: Limit intake to reduce added sugar consumption.
• Red and Processed Meats: Minimize consumption to lower saturated fat and sodium intake.
• Sodium: Monitor and reduce sodium intake to maintain healthy blood pressure levels.
• Alcohol: If consumed, do so in moderation, adhering to recommended guidelines.

AHEI and Healthy Ageing

Recent studies have highlighted the AHEI’s predictive power regarding healthy ageing. Research involving over 100,000 participants over 30 years found that individuals with higher AHEI scores had a significantly greater likelihood—up to 86%—of reaching age 70 without chronic diseases and with intact cognitive, physical, and mental health.

Moreover, higher AHEI scores have been associated with:

• A 19% lower risk of chronic disease.
• A 31% reduction in coronary heart disease risk.
• A 33% decrease in diabetes risk.

These findings underscore the AHEI’s utility in guiding dietary choices that promote healthy ageing.

Practical Steps to Improve Your AHEI Score

Enhancing your AHEI score involves making informed dietary choices:

• Increase Plant-Based Foods: Emphasize vegetables, fruits, whole grains, nuts, and legumes in your meals.
• Choose Healthy Fats: opt for unsaturated fats found in oils like olive and canola.
• Limit Unhealthy Options: Reduce intake of sugary beverages, red and processed meats, and high-sodium foods.
• Moderate Alcohol Consumption: If you drink alcohol, do so in moderation, following health guidelines.

Conclusion

The Alternative Healthy Eating Index serves as a valuable framework for assessing and improving diet quality, with a direct impact on healthy ageing.
