They start their three-match series at Trent Bridge after a 2-1 defeat in the T20 matches.
England set a new ODI record of 481 for six when they beat Australia in Nottingham last month.
Another big score is expected but Root has dismissed suggestions England are ready to break their own marker.
He said: “It’s dangerous to think too far ahead. One thing we have been good at is assessing things early on an planning an innings.
“It might be the case, it might not, but ultimately it’s about winning the series and coming out of what has been an impressive white ball summer.”
England are the number one ranked ODI team in the world and whitewashed Australia 5-0 in their most recent series.
India sit second in the rankings and Root expects a difficult tussle following the T20 series defeat.
He added: “India have been a really strong team in this format for a long time. Ultimately it’s good marker to see where we’re at.
“It’s an important series, we have played some really strong cricket in one day format and India are one of the best in the world.”
Meanwhile, India vice-captain Rohit Sharma insists their one-day international tour will be crucial to their World Cup preparations.
England and Wales host the World Cup next year with Sharma eager to get some early practice in.
He said: “It is very important, since the World Cup is going to be played in this part of the world.
“In terms of preparation it’s very important, in terms of our combinations and what our targets are going to be.
“We have seen England against Australia and they were really high scoring games, it’s gong to be crucial to see where we are as a team.
“In the last year or so we have played some good cricket, in and out of India, this tour brings another challenge for us.”

Roger Federer is not only one of the greatest tennis players of all time, he is also one of the most beloved athletes of the 21st century. Sports enthusiasts and players from across disciplines look up to him for his spectacular achievements and the grace with which he carries himself and plays the game.
The Swiss great eased past France’s Adrian Mannarino to reach his 16th Wimbledon quarter-final on Monday. During the match, Wimbledon’s Twitter account posted a video of Federer playing what resembled a cricket shot.
The All England Club tournament asked the International Cricket Council what it thought of Federer’s ‘forward defence’.
The ICC’s social media responded by bumping Federer right to the top of Test ranking for batsmen.
They weren’t done as the governing body wondered, in a following tweet, how Federer will fare against England seamer Stuart Broad.
Federer and cricket have crossed paths in the past. Sachin Tendulkar has called the 36-year-old his favourite player and the two met at SW19 in 2011. Sachin and Virat Kohli attended Wimbledon matches together in 2015.
Which is why the India batting great had his say in Federer’s ‘rise’ to the No1 ranking. Tendulkar took to twitter and asked Federer if they can exchange notes ‘after you win your ninth Wimbledon title’.
