Streeting said: "GPs have really embraced this. You would think from listening to some of the moaning minnies in the BMA that GPs have been resistant, they're not doing this.
"Actually the overwhelming majority have, and I'm thankful to them," he said.
According to new figures from the Office for National Statistics (ONS), a higher proportion of people in England are now contacting their GP surgery online than by phone.
Data covering three weeks from mid-September suggest just over 43% of people went online to contact their GP - an increase of a percentage point from the previous month - compared with 41% percent on the phone.
Streeting has heralded the figures as "a massive step" towards meeting the government promise to end the "8am scramble for appointments".
