Introduction

Milk tea, commonly known as chai, is a beloved beverage across many households, made by brewing black tea with milk, sugar, and often warming spices like ginger, cardamom, or cloves. For many people, it's more than just a drink — it's a daily ritual tied to comfort, hospitality, and conversation, often enjoyed multiple times a day.

While chai is culturally significant and genuinely comforting, its combination of caffeine, tannins, milk, and sugar means that drinking it in excess every day can bring a few notable health considerations. Understanding these effects can help you enjoy your daily cup while staying mindful of how much you're having and when.

What is milk tea?

Milk tea, widely known as chai in India, is made by brewing black tea with milk, sugar, and often warming spices like ginger, cardamom, or cloves. It's a daily ritual for many households, valued for its comforting taste and mild energising effect from caffeine.

While a cup or two can be part of a balanced routine, milk tea's combination of caffeine, tannins, and added sugar means regular overconsumption can bring on a few unwanted side effects over time.

Drinking milk tea in excess, especially daily, may lead to the following effects:

1. Digestive discomfort: Tannins can increase stomach acid production, leading to acidity or indigestion, especially on an empty stomach.
2. Reduced iron absorption: Tannins bind with non-heme iron in the digestive tract, potentially reducing its absorption over time.
3. Weight gain: Added sugar and full-fat milk can contribute meaningfully to daily calorie intake.
4. Caffeine dependence: Regular consumption can lead to mild dependence, with symptoms like headaches or irritability if skipped.
5. Sleep disruption: Caffeine can stay in the body for 6-8 hours, potentially affecting sleep quality if consumed later in the day.
6. Dehydration: Caffeine has a mild diuretic effect, which may contribute to fluid loss if fluid intake isn't balanced.
7. Increased heart rate: Excess caffeine may cause palpitations or anxiety in sensitive individuals.
8. Dental issues: Added sugar can contribute to tooth decay with frequent consumption.
9. Constipation: High tannin intake has been linked to constipation in some individuals.
10. Blood sugar fluctuations: The sugar and caffeine combination may cause an energy spike followed by a crash.

Certain groups should moderate or avoid milk tea, particularly in larger amounts:

• Pregnant women: Due to caffeine limits recommended during pregnancy.
• People with iron deficiency or anemia: Tannins may further reduce iron absorption from food.
• Those with acid reflux or GERD: Milk tea's acidity may worsen symptoms.
• People with anxiety or heart rhythm concerns: Caffeine sensitivity may worsen symptoms like palpitations or restlessness.
• Individuals with insomnia or sleep issues: Caffeine's stimulating effect can further disrupt sleep patterns.

For most healthy adults, moderate milk tea consumption is generally considered safe:

• A common guideline is 1-3 cups of milk tea per day, depending on individual caffeine sensitivity.
• Spacing milk tea at least 1-2 hours away from meals can help reduce its effect on iron absorption.
• Reducing added sugar and opting for low-fat milk can help limit calorie intake from regular consumption.

Conclusion

Milk tea is generally safe to enjoy in moderation, but daily overconsumption can lead to digestive discomfort, reduced iron absorption, and disrupted sleep due to its tannin, caffeine, and sugar content. Sticking to around 1-3 cups a day, spacing it away from meals, and being mindful of added sugar can help you enjoy chai without the downsides. Those with anemia, acid reflux, or caffeine sensitivity should be especially mindful of their intake.
