Dietary habits and meal timing impact blood sugar levels

Recent studies highlight how dietary choices and meal timing significantly influence blood sugar levels and metabolic health.

A study involving healthy individuals found that consuming 250ml of lemon juice with 100g of bread can reduce postprandial blood sugar peaks by approximately 30% and delay the peak by about 35 minutes compared to consuming bread with water or black tea. Experts suggest the acidity of lemon juice may inhibit alpha-amylase, the enzyme responsible for breaking down starch, thereby slowing glucose absorption. However, this is not a substitute for medical treatment for diabetes.

Additionally, research from Johns Hopkins University indicates that meal timing plays a critical role in metabolic efficiency. In a study of 20 healthy adults, those who ate dinner at 10:00 PM experienced higher blood sugar spikes and lower fat metabolism rates compared to those who ate the same meal at 6:00 PM. This effect is attributed to rising melatonin levels at night, which can interfere with glucose regulation. Experts recommend eating dinner between 5:00 PM and 7:00 PM, ensuring at least a two-hour gap before sleep to maintain metabolic health.
