WHY TO LIMIT IT ON KETO
- High net carbs (~18.7g/100g) exceed typical keto budgets
- Starchy profile (mostly glucose-yielding) raises glycemic load
- Even small servings can push you out of ketosis
- Lower-carb vegetables offer similar nutrients with fewer carbs
HEALTH BENEFITS
- Provides some fiber that supports digestion (outside strict keto)
- Contains B vitamins for energy metabolism
- Supplies lutein and zeaxanthin for eye health
- Includes antioxidants that may reduce oxidative stress
- Contains minerals like magnesium and potassium
- Cooling then reheating can increase resistant starch (still high net carbs)
PREPARATION SUGGESTIONS
GRILLED (OCCASIONAL TREAT)
Grill in husks 15–20 minutes, turning. Brush with butter and herbs; reserve for special occasions.
BOILED (LIMITED)
Boil 5–7 minutes until tender. Keep portions very small—use a spoonful of kernels as garnish.
SALSA GARNISH
Fold 1 tbsp kernels into salsa for color/texture. Track carbs carefully.
SOUP TOPPER
Sprinkle a few kernels on low-carb soups for contrast; measure to manage carbs.
