Sweetcorn isn't typically fattening when enjoyed in moderation as part of a balanced diet. Here’s why:

1. Calorie Content: With just 90-100 calories per ear, sweetcorn is a low-calorie option compared to many other foods.
2. Nutritional Benefits: It's packed with essential vitamins and minerals like vitamin C, B vitamins, potassium, manganese, and magnesium, which support overall health.
3. Fiber Power: Each ear provides about 2 grams of fiber, aiding digestion, promoting fullness, and assisting with weight management.
4. Low in Fat: Naturally low in fat, with only about 1 gram per ear, it’s a great choice for those watching their fat intake.
5. Carb Count: While it does have around 19 grams of carbs per ear, it's still a healthy option if portion sizes are monitored, especially for those on low-carb diets or managing diabetes.
6. Preparation Matters: How you cook your corn matters. Boiling or grilling it without added fats keeps it healthy, while adding butter or oil bumps up the calorie count.
7. Weight Studies: A Harvard study noted a modest weight gain (2 pounds over 4 years) with daily corn servings, which is less than the gain from other starchy veggies like potatoes.

In essence, sweetcorn is a nutritious and low-calorie choice when enjoyed in moderation, making it a great addition to a healthy diet.

Is Canned Sweet Corn Healthy?

Canned sweet corn, especially when it’s just corn and water, is a convenient and healthy food option. Here’s what makes it great:

2. Low-Calorie and Low-Fat: A half-cup serving has only 77-100 calories and about 1 gram of fat, making it a light and healthy choice.
3. Protein and Fiber: Provides around 3 grams of protein and plenty of fiber, promoting a healthy digestive system.
4. Antioxidants: Packed with antioxidants like vitamin C, lutein, and zeaxanthin, which are great for your eyes.
5. Long Shelf Life: It lasts 3-5 years when stored properly, making it a handy pantry staple.

A few things to watch out for:

1. Sodium Levels: Some brands add salt, so check labels and opt for low-sodium versions.
2. Carbs: With about 15 grams of carbs per half-cup, it’s something to monitor if you're managing your carb intake.
3. BPA Concerns: While some cans may contain BPA, many manufacturers have moved away from using it.
