## Slice by slice

| Item | Per 100 g / 100 mL | Serve | Energy | Calories |
|---|---|---|---|---|
| White bread, toasted, one slice | 1,224 kJ/100 g | 35 g | 428 kJ | 102 Cal |
| Vegemite | 755 kJ/100 g | 5 g | 38 kJ | 9 Cal |
| Butter or dairy blend | 3,000 kJ/100 g | 9 g | 270 kJ | 65 Cal |
| Margarine spread, monounsaturated | 2,500 kJ/100 g | 9 g | 225 kJ | 54 Cal |
| Avocado, hass, raw | 653 kJ/100 g | 40 g | 261 kJ | 62 Cal |
| Egg, poached | 555 kJ/100 g | 50 g | 278 kJ | 66 Cal |

## How people actually eat it

| How it is eaten | Energy | Calories | Protein |
|---|---|---|---|
| One slice, Vegemite only | 466 kJ | 111 Cal | ~3.5 g |
| One slice, butter and Vegemite | 736 kJ | 176 Cal | ~3.6 g |
| Two slices, butter and Vegemite | 1,472 kJ | 352 Cal | ~7 g |
| Two slices with Vegemite, avo and a poached egg | 1,531 kJ | 366 Cal | ~14 g |

## The spread is the whole story

Vegemite itself is almost free: 5 g carries 38 kJ and nearly 1.3 g of protein. The butter underneath costs seven times more than the Vegemite on top. Scraping instead of spreading, or using a reduced-fat spread, takes 100 to 150 kJ off every slice without changing the taste much.

Wholemeal bread lands within about 20 kJ of white per slice but brings roughly double the fibre, which is the change worth making if you are choosing between them.
