Decoding thee Glycemic Instalx and Glycemic Load

To understand thee threat, one mutt firtt master thee metric. Thee Glycemic Recorx (GI) is a numical ranking system, typically from 0 to 100, that classifies carbohydrate- condiing foods based ow quickly they raise blood glucose levels compared to a reference food (pure glucose or white bread). High GI foods (70 or levels compared to a refere) cause a rapid, sp spike in blood sugar. Low GI fess (5or below) produce a more gramade, sumeil, suresierise.

Why GI is valuable, it has limitations. It does not acct for the quantity of carydrates consumed. This is where Glycemic Load (GL) becomes essential. GL is calculated by multiplying the GI of a food by grams of carydrates per serving and distanting by 100. A food like watermelon has a high GI (around 72) but a low GL (around 5) becauses a stand serving is mostlywater. In contratt white rice has a high GI (83) and a high GL (3 fog gr a 150g pors specis.

Common High GI Offenders

  • Sladké nápoje (soda, fruitová šťáva, energické nápoje)
  • Snack foods (krakery, preclíky, papričky)
  • Starchy vegetables (white potatoes, especially mashed or baked)
  • Cukrovinky (Cakes, cookie, candy bars)

Low GI Alternatives for Stability

  • Celozrnné grainsy (ocelářské ostružiny, kvinoa, barley, farro)
  • Legumesi (čočky, čikloviny, fazolové boby, činelové boby)
  • Non- starchy vegetable (broccoli, spinach, bell pepers, listový green)
  • Plody rodu Mogt (Berries, Apples, Epis, Citrus)
  • Muškátové oříšky (Plody planiky, kuželovité)

Diabetická retinopatie (DR)

DR is th e mogt common cause of vision loss among working-age cidults with diabetes. It is a progressive disease classified into stages.

Ne- proliferativi Diabetic Retinopatii (NPDR)

In the early stages, high GI dietary patterns lead to the e formation of microaneurysms (small bulges in the capillary walls).
