What is Avg Food Quality?
Avg Food Quality measures the nutritional value of the foods you log in your diet. It reflects how well your eating habits align with high-quality nutrition — favouring whole, nutrient-dense foods over processed or refined options.
Why does it matter for long-term health and wellbeing?
Maintaining a high Avg Food Quality supports balanced energy, nutrient sufficiency, and healthy metabolic function. Studies consistently show that higher diet quality is linked to improved overall wellbeing, reduced inflammation, and better physical performance. Tracking this biomarker gives insight into how your daily food choices influence your long-term vitality.
What’s an optimal level of Avg Food Quality?
- Optimal: 100% (average 9–10)
- Very good: 80% (average 8–9)
- Good: 60% (average 6.5–8)
- Sub-optimal: 40% (average 5–6.5)
- Pay attention: 20% (average 5)
These ranges are based on validated dietary quality frameworks used in Australian nutrition research and provide a practical guide for lifestyle improvement.
What influences Avg Food Quality levels?
- The proportion of whole vs processed foods in your diet
- Intake of fruits, vegetables, legumes, and whole grains
- Frequency of discretionary foods high in added sugars, fats, or sodium
- Meal planning, variety, and portion sizes
- Hydration, alcohol intake, and consistency across meals
What does it mean if Avg Food Quality is outside the optimal range?
Scores below 80% suggest your diet may include more processed or nutrient-poor foods than recommended. This doesn’t mean poor health — it simply signals an opportunity to improve balance and variety. Adjusting portion sizes, adding colourful produce, and reducing packaged foods can help lift your score over time.
How can I support healthy Avg Food Quality levels?
- Choose whole, unprocessed foods most of the time
- Increase daily servings of vegetables, fruits, and legumes
- Swap sugary or refined snacks for nuts, seeds, or yoghurt
- Prepare meals at home to have more control over ingredients
- Track your food choices regularly to stay aware of your progress
