Evaluation of the effect of inhibitors in black tea and green tea on the digestion of milk proteins, lipids and starch by the enzymes trypsin, lipase and amylase:
My experiment was to investigate whether green or black tea (Camellia sinensis) can act as inhibitors and affect the action of digestive enzymes (trypsin, lipase, and amylase) in vitro. This was done by measuring the zones of digestion around wells in protein, lipid, and starch agar plates where black or green tea was added. The results showed large zones of digestion around the control wells with only the enzymes and the zones were significantly smaller for the wells that contained both the tea and enzymes, that showed that tea inhibited the digestion of each of the substrates by the enzymes. However, the inhibition for green tea on amylase was not significant. The results of this investigation showed that black tea and green tea do inhibit the enzymes trypsin and lipase however, only black tea inhibits amylase.

Should I stop drinking tea now? Also is coffee better?
Hi!
No, it does not mean you need to stop drinking tea as these are very different concentrations to those that would occur if you were to drink tea with meals. So further investigations would have to be made to determine if it had an effect in vivo rather than in vitro as in this investigation.
I don’t know if coffee would be better, but it would be interesting to find out if it has a similar effect to tea. I had a quick look and the polyphenols in coffee do seem to inhibit some of the digestive enzymes similarly to how polyphenols in tea are thought to be responsible for the digestion by these enzymes.
