To graph the data in a bar graph, we will place the food items on the x-axis and the tryptophan mg per 3 oz serving on the y-axis.

Here is the bar graph:

```
Tryptophan mg per 3 oz serving

250 +
|
200 + cheddar cheese
| |
150 + |
| |
100 + peanuts |
| | |
50 + | |
| | |
0 +-------+-------+-------+-------+-------+-------+
turkey chicken beef banana oats
```

The x-axis is labeled with the food items: turkey, chicken, beef, peanuts, cheddar cheese, banana, and oats.

The y-axis is labeled with the tryptophan mg per 3 oz serving scale from 0 to 250.
