Nutritional Comparison for Bread, Rice, Pasta, Potatoes, Tortillas and Fortified Cereal


I love carbohydrates;  large bowls of rice, pasta or cereal, tortillas with cheese melted on top, and baked potatoes with butter.  A few weeks ago I bought some GMO free bread and ate four slices per day until the loaf was gone.

Because I eat a lot of carbs I decided to find out which ones are the healthiest.

I compared nutrition information for bread, rice, pasta, potato, tortilla and cereal side by side in a table (see below).  I did not include sugar and fat in the table because they are similar.  Fat grams ranged from 0.2 - 3 grams per serving and sugar ranged from 0.1 - 2 grams per serving.

I was surprised to learn that in addition to cereal;  bread, pasta, and rice are fortified with nutrients and minerals such as iron, folate, thiamin, niacin, and riboflavin.

Comparison summary for bread, rice, pasta, potato, tortilla and cereal: 
  • Tortillas have the most sodium (200 mg) and pasta has the least (0 mg)
  • Rice and pasta have the most calories (206, 200 calories respectively)
  • Rice has the most carbs (45 g) and bread has the least (15 g)
  • Potatoes have the most fiber (4.7 g) and rice has the least (0.6 g) 
  • Pasta has the most protein (7 g) and tortillas (2.5 g) have the least 
  • Tortillas have the lowest Glycemic Index (GI) (30) and potatoes have the highest (85)
  • Potatoes have a lot of Vitamin C and potassium
  • Cereal (Cheerios) has the most added iron (45%)

Typically I eat cheerios for my carb fix, 2 - 3 bowls every day.  However, based on this investigation I am going to eat baked potatoes instead of cereal because of the significant amount of Vitamin C and potassium in potatoes. 

Although cereal has quite a bit of sodium (140 mg) compared to pasta, rice and potatoes I don't eat many other foods with sodium and I don't have any issues with high blood pressure.  Although potatoes and cereal have a high Glycemic Index (GI) (85 and 74 respectively) I am careful to monitor what I eat if I feel hungry again shortly after eating.

You should decide what is best for you based on your diet and body.   I hope this summary table helps! 

Background Info

Dietary Guidelines for Carbohydrates -  Carbohydrates should make up 45 to 65 percent of your total daily calories.  So, if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbohydrates a day.  Mayo Clinic   But if you need to lose weight, you will get much faster results eating around 50 to 150 grams of carbs. HealthLine  

Glycemic Index (GI) - Glycemic index rates foods that contain carbohydrates on a scale of 1 to 100. Foods on the lower end are considered low-glycemic foods, while foods closer to 100 are high-glycemic foods. Foods with a GI rating closer to 100 cause your blood sugar to spike suddenly and then drop to a lower level than it was in the first place. When this happens, you may feel hungry again shortly after eating.  Healthy Easting 

Benefits of Potassium - Potassium supports blood pressure, cardiovascular health, and bone and muscle strength.  Adults should consume 4,700 mg per day.  Medical News Today
