Some Final Words

If you are planning to make one or more of these nuts as your primary source of iron then you must think twice about it. Say, for example, an adult woman needs about 18 mg of iron in a day and for that, she would have to eat approximately 269 grams of cashews.

That is more than 100 cashews a day and this practice is certainly not healthy because nuts are usually high in calories.

  • 100 grams of nuts usually packs around 617 calories, accounting for a significant portion of your daily recommended calorie intake.
  • Excessive nut consumption may result in bloating.
  • On top of that most nuts have a high omega 6 content that messes up the omega 3 to omega 6 fat ratio. This is why overconsumption of nuts can cause inflammation.

Although, it should be mentioned again that it depends on the quantity as the inflammatory qualities of nuts are far outweighed by the other nutrients. So, eating 5 walnuts a day won’t harm your health but eating 100, will.

Therefore, the wise thing to do would be to make nuts one of the many iron sources for a balanced and healthy diet.
