## Step 1: Define the optimization problem
The goal is to maximize the objective function: $5 \times \text{milligrams of potassium} + 2 \times \text{grams of fat} + 4 \times \text{grams of fiber} + 5 \times \text{milligrams of calcium}$.

## Step 2: List all the constraints
The constraints are given in the problem description. They include:
- Immune support index constraints
- Cardiovascular support index constraints
- Cognitive performance index constraints
- Energy stability index constraints
- Upper and lower bound constraints for each variable and their combinations.

## 3: Translate constraints into mathematical expressions
Due to the complexity and the number of constraints, we will directly implement them in Gurobi code.

## 4: Implement the optimization problem in Gurobi
We will use Gurobi's Python API to model and solve the optimization problem.

```python
import gurobi as gp

# Create a new model
m = gp.Model("optimization_problem")

# Define the variables
milligrams_of_potassium = m.addVar(name="milligrams_of_potassium", lb=0)
grams_of_fat = m.addVar(name="grams_of_fat", lb=0)
grams_of_fiber = m.addVar(name="grams_of_fiber", lb=0)
milligrams_of_calcium = m.addVar(name="milligrams_of_calcium", lb=0)
