Glycemic Index
GIA low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
A simple, calorie-free hot drink of green tea steeped at the right temperature, with a squeeze of fresh lemon. GI 20, GL 0, just 7 calories — the ideal daily ritual.
Green tea is the most consumed tea in the world, with a tradition stretching back thousands of years in China and Japan, where it is drunk plain and with reverence for its delicate taste and clarity. The addition of lemon juice is a simple touch that brightens the flavour and, importantly, stabilises the catechins — the main antioxidant compounds in green tea — making them easier for the body to absorb.
Green tea arrived early in the Gulf alongside trade routes, though it sits alongside the stronger tradition of black tea and Arabic coffee. It has found a new audience in the region as a lighter, calorie-free alternative, drunk between meals and in the morning before breakfast.
Heat the water until it reaches approximately 80°C — just below boiling. If using a kettle without temperature control, boil the water and let it sit for 2 to 3 minutes before pouring. Boiling water (100°C) burns green tea and makes it bitter; the lower temperature extracts the delicate flavour and antioxidants gently.
Place the green tea bags or loose tea in the teapot or cups. Pour the 80°C water over them and steep for exactly 2 to 3 minutes. No longer — even 30 extra seconds can add unwanted bitterness. Remove the tea bags immediately or strain the loose tea.
Squeeze the lemon juice into the tea and stir gently. The acid from the lemon helps stabilise the catechins (the main antioxidant compounds in green tea) and makes them more absorbable. It also brightens the flavour.
Add the teaspoon of honey if desired and stir until dissolved. Add the fresh mint leaves as a garnish. Serve immediately while hot.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.

The most common problems when preparing Green Tea with Lemon, and how to fix them:
The water was too hot or the steeping time too long. Use 80°C water and steep for exactly 2 to 3 minutes. If already brewed, add a thin slice of fresh lemon to the cup — the acid cuts through bitterness.
Too little tea or too much water. Use 1 bag or 1 teaspoon of loose tea per 200 ml of water. Check that the tea is not stale — green tea loses its flavour quickly if stored improperly.
Oxidation from water that was too hot or tea that is past its best. Use the correct temperature and check the tea's best-before date. Store green tea in an airtight container away from light.
Store green tea bags or loose tea in an airtight container away from light, heat and moisture. Keeps for 12 to 18 months from the date of packaging. Green tea loses its delicate flavour faster than black tea if stored poorly.
Best consumed immediately after brewing. If making ahead, brew without the lemon, refrigerate in a sealed jar for up to 1 day, and add the lemon just before drinking. Do not leave brewed tea at room temperature for more than 2 hours.
For cold brew: place tea bags in cold water and refrigerate for 6 to 8 hours. Cold brewing extracts a sweeter, less bitter flavour. Add lemon and honey as normal before serving over ice.
| Original Ingredient | Tested Substitute | Ratio | Flavor Difference |
|---|---|---|---|
| Green tea bags | Japanese matcha powder | 1/2 teaspoon per cup | Matcha is powdered green tea that is whisked into hot water rather than steeped — the entire leaf is consumed, giving a higher concentration of catechins and caffeine. Use a bamboo whisk or small regular whisk. |
| Fresh lemon | Fresh lime juice | Same amount | Lime provides the same acid benefit with a slightly different aroma — more fragrant and tropical. Works well with mint. |
| Honey | Stevia drops or a pitted date steeped in the cup | To taste | Zero-calorie sweetening option for those monitoring blood sugar. A date adds a gentle sweetness and Gulf character. |
| Hot preparation | Iced green tea with lemon | Same amounts, then pour over ice | Brew the tea as normal, allow to cool, then pour over ice. Refreshing in hot Saudi summers. |
| Number of cups | Tea | Water | Lemon |
|---|---|---|---|
| 1 (single) | 1 teaspoon | 1 cup | 1/2 spoon |
| 2 (base) | 2 teaspoons | 2 cups | 1 tablespoon |
| 4 (pitcher) | 4 teaspoons | 4 cups | 2 spoons |
| 6 (guests) | 6 teaspoons | 6 cups | 3 tablespoons |
The most important thing about brewing green tea is the water temperature: 80°C, not boiling. Boiling water destroys the delicate catechins and produces bitterness. Lemon juice adds a practical benefit beyond flavour: the citric acid stabilises the catechins and research suggests it increases their absorption in the small intestine. Avoid adding milk — milk proteins bind to the catechins and reduce their bioavailability. And note: green tea contains caffeine (about 25 to 35 mg per cup, versus 80 to 100 mg in coffee) — suitable for daytime but avoid close to bedtime for those sensitive to caffeine.
