Dietary Intake Profile

Estimated daily intake of key dietary risk factors in Tonga vs. optimal ranges from the Global Burden of Disease study.

⚠️ Approximate. Intake estimated from FAO food supply ÷ caloric density. Values reflect food availability (not consumption) and include waste. "Cereals" includes all grains, not only whole grains. Sodium excluded because food supply data cannot capture added salt.

Dietary Health Impact

Deaths attributable to dietary risk factors in Tonga (GBD 2023). These are modeled estimates — not direct counts.

In 2023, an estimated 141 deaths in Tonga were attributable to dietary risk factors (GBD 2023). The leading dietary risk was low whole grain intake, linked to 41 deaths.

vs. EAT-Lancet Reference Diet

How Tonga's food supply compares to the EAT-Lancet Planetary Health Diet — the scientifically-derived dietary pattern for human and planetary health.

⚠️ Approximate comparison. FAO food supply data measures availability (not intake) and uses different food group definitions than the EAT-Lancet framework. Bars show directional patterns, not precise gaps.

Estimated Nutrient Adequacy

How well Tonga's food supply meets estimated average requirements (EAR) for key micronutrients.

⚠️ Rough estimate. Derived from FAO food supply × USDA nutrient composition — not from direct dietary intake surveys. Values represent supply-level adequacy and will overestimate actual intake (food waste reduces intake ~20–30%).

Frequently Asked Questions

How many calories per day does Tonga produce?

Tonga's food supply provides approximately 3,059 kcal per person per day as of 2023, according to FAO Food Balance Sheets. This measures food availability, not actual individual consumption — household-level waste typically reduces actual intake by 20–30%.

How has Tonga's diet changed over time?

Between 2019 and 2023, Tonga's total calorie supply changed from 2,898 to 3,059 kcal/capita/day (an increase of 6%). Protein supply went from 130.7g to 129.3g per day. Fat supply changed from 117.0g to 124.1g per day.

Where does Tonga rank globally?

Tonga ranks #86 out of 200 countries by calorie supply per capita. The world average is approximately 3,016 kcal/capita/day.

How does Tonga's diet differ from the world average?

The butterfly chart above shows the difference in food supply composition between Tonga and the global average. Bars extending to the right indicate food groups where Tonga consumes more than the world average, while bars extending left show deficits. These differences reflect agricultural production, cultural food traditions, income levels, and trade patterns.

What are dietary risk factors?

Dietary risk factors are eating patterns linked to chronic disease and premature death, as modeled by the Global Burden of Disease (GBD) study. The five major dietary risks are: high sodium intake, low fruit intake, low vegetable intake, low whole grain intake, and low nut and seed intake. These are population-level statistical estimates — not direct counts of individual deaths.
