* there are also changeCalories, * changeFat, changeCarbohydrate,
* changeCalories functions
*/
food.changeAmount(23);
// get current nutrition values of rice
const {
calorie,
amount,
fat,
carbohydrate,
protein
} = food.getCurrentValues()
// get base nutrition values of rice
const {
calorie,
amount,
