The concept involves using technology, such as smartphones and software, to help people chose food and drink best suited to their health needs.
UHI believes it could offer protection from allergies and too many calories.
The idea is similar to the "internet of things" which sees domestic products, such as washing machines, being controllable via online tools.
Prof Maged Boulos, an expert in digital health at UHI, who is leading the research, said: "A new breed of automated food scanner apps, devices and methods is emerging which aim at identifying the nature of food and drinks in our diet.
"Methods include barcode scanning, weighing with portable electronic scales, measurement of weight/portion size with smartphone photos and remote food and drink recognition by crowdsourced volunteers or dieticians.
"However, these methods are of limited value if we cannot reason with the identified food and drink items in the context of a user's health conditions and preferences."
Prof Boulos said increased use of technology to help people make selections of food and drink could greatly improve health.
However, he added that it would require further research and funding.
Prof Boulos said: "This will be a huge academic undertaking involving multiple research centres, universities and industry.
"Based on the development of other technologies of similar scale, it will likely require several years and millions of euros of funding to complete an initial base version."

Crawford Falconer will take up the post of chief trade negotiation adviser at the Department for International Trade.
Leaving the single market would mean the UK would have to establish new bilateral trade agreements, but cannot formally do so until after Brexit.
However, one economist suggested Mr Falconer would already be "building bridges" with the European Commission.
The UK faces a huge challenge in resetting its trading relationship with the EU and other countries when Brexit takes effect.
Trade pacts that have been negotiated by the EU with the rest of the world will no longer apply to the UK, while Britain will also need to define new trading relationships with the EU itself.
Membership of the EU has meant the UK does not have a large bank of trade negotiators with recent experience.
A New Zealander, Mr Falconer has more than 25 years trade experience. He has represented New Zealand at the World Trade Organization (WTO) and held various posts in foreign and trade affairs in his home country.
Prof Alan Winters, from the University of Sussex's UK Trade Policy Observatory, said Mr Falconer's experience and contacts at the WTO would mean the groundwork for separating UK trade policy from Brussels would be made easier.
"He knows quite a lot of the main players at the WTO and can build bridges at the European Council, which is good as there is work to be done right now," he said.
"There is work he can do, such as discussions on whether the UK uses replicas or changes trade agreements that we have with nations by way of membership with the EU."
One suggestion has been that initially trade agreements could be adopted by the UK in their current form - replicating them - at the point of Brexit, to be altered subsequently as new deals are agreed.
International Trade Secretary Liam Fox said of the new appointee: "Crawford Falconer brings a wealth of international trade expertise to our international economic department, ensuring that as we leave the EU, the UK will be at the forefront of global free trade and driving the case for international openness."
Mr Falconer will lead trade policy and negotiation teams at the DIT. His appointment was first announced in June.
University of the Highlands and Islands (UHI) scientists have been exploring the idea of the "internet of food".
