To determine which food contains the most kcal/gram based on the saturated fat content, we need to evaluate the data provided for each food. The provided data tabulates the amount of saturated fat in various foods.
Here's the list:
- Olive oil: 2 grams of saturated fat
- Margarine: 2 grams of saturated fat
- Butter: 7 grams of saturated fat
- Lard: 5 grams of saturated fat
- Canola oil: 1 gram of saturated fat
Since fat provides approximately 9 kilocalories (kcal) per gram, we can find the kcal/gram for each food by multiplying the amount of saturated fat by 9.
Now, let's review each food:
1. Olive oil
[tex]\(2 \text{ grams of saturated fat} \times 9 \text{ kcal/gram} = 18 \text{ kcal/gram}\)[/tex]
2. Margarine
[tex]\(2 \text{ grams of saturated fat} \times 9 \text{ kcal/gram} = 18 \text{ kcal/gram}\)[/tex]
3. Butter
[tex]\(7 \text{ grams of saturated fat} \times 9 \text{ kcal/gram} = 63 \text{ kcal/gram}\)[/tex]
4. Lard
[tex]\(5 \text{ grams of saturated fat} \times 9 \text{ kcal/gram} = 45 \text{ kcal/gram}\)[/tex]
5. Canola oil
[tex]\(1 \text{ gram of saturated fat} \times 9 \text{ kcal/gram} = 9 \text{ kcal/gram}\)[/tex]
By comparing all the kcal/gram values, we see that butter has the highest amount of kilocalories per gram due to its saturated fat content.
Therefore, the food that contains the most kcal/gram, based on the data in the table, is:
Butter
