Dietary Management: Balancing Symptomy a d Nutrition

Low- - Lactose vs. Dairy- Free

Ne all dairy is high in lactose. Hard cheeses like cheddar, Parmesan, and Swiss contain very little lactose because mogt of the whey (where lactose resides) is removed during procesing. Butter and clarified butter (ghee) are also low in lactose. Yogurt and kefir, evellythose consiing live active cultures, can beaeasiear to digeset becausese their their own lacattase. Howeveur, in Crohn 's eeeeeeeeeve low-lactosi may may poorly gratate guif.

Calcium and Vitamin D Alternatives

Avoiding dairy can lead to sufficient calcium and acredin D intaxe, which is particarly concerning for Crohn 's patients who o already have e increared risk for metabolic bone diseasease. Non -dairy sources of calcium include:

  • Mléčné výrobky z fortifiedu plantu (almond, soy, oat, rice)
  • Rostlinné rostliny (kale, collard greens, broccoli)
  • Calcium- set tofu
  • Canned fish with bones (sardines, salmon)
  • Calcium- fortified orange juice and cereals

Vitamin D can be dosaged from sun exposure, fatty fish, egg yolks, and supplements. Ingrese absorption may be compromised in Crohn 's, blood levels should d be monitored regularly.
