BEWE and taxation link

How can the teenagers BEWE be linked to our taxation.
An individual's tooth erosion and how to treat it is more prevalent now than in the 1980s when I qualified. It's a gift that keeps on giving for our income stream. But if they become diabetic or obese with a reduced working lifespan which may affect their taxable income, and take up more NHS resources care in our old age?
While our grandchildren may ask, "why did you ruin our planet?", it will be more devastating to both of us when they ask why did you not promote healthy eating? We know UPFs( Ultra processed foods), and UPDs (Ultra Processed drinks)  cause increases in obesity, type 2 diabetes, and many other health problems. 
We are in a prime position to promote health. Long lectures on sugar's evils have rarely worked in the surgery environment. We need to give consistent nudges to support general health advice. We can influence our patients who trust us by using modern technology to support our messages, promote specific information, and allow the user to make their choices for the sake of their health and the health of our national economy. 
The food industry learnt from big tobacco how, when, and where to intervene to maintain their profits. For example, Save the Children withdrew its concerns about sodas following a $ 10 million payout for local Bangladesh funding. Multi-national food companies don't have to pay for the long-term health consequences. It made commercial sense to help maintain their $47 billion worldwide revenues ( from Soda Politics around 2010).
Is it different in the UK? Have we just backtracked on UPFs? Is the consumption of UPDs going down? Is history repeating itself? Can we do anything?

As the highest growth in obesity is in the teenage group, should we be concerned for their health, our pension, or both?
To help us all get better, why not help one another, similar to how Team GB won so many cycling medals in 2012. It wasn't one person. It was a team effort of coaches and diverse experts in their field, collaborating outside their specific areas with other professions and making many minor improvements. As we are in the sphere of influence and trusted health professionals, can't we suggest a few simple nudges to encourage the public to consider the consequences of their actions for themselves and their families?

More recently, due to global warming, governments worldwide have intervened and introduced policies that have promoted disruptive innovations such as electric cars and bikes.
Why not for health? With life expectancy decreasing, increasing the pensionable age does not seem like a great solution, although it will help balance the books. Many of us are retiring while we can. We could help those who may never make it? We can market healthy living at every opportunity using advanced digital media and digital sensors that weren't available in the 80s. 

It needs collaboration to agree on essential health advice that a consensus can decide on concerning oral health and general health.
We can deliver it for free with some focussed videos on oral health, as well as dietary advice with some reference to the evidence and how to self-monitor for other diseases such as Oral Cancer.
We don't need to be experts in all fields, but we can share our experiences and expertise to help improve our general health even if the government no longer has the funding to support dentistry, or mental health, or social care. It's worth a try. Do you want to help?
Perhaps our collective action on libertarian paternalism will prompt a government into prevention rather than cure. Governments worldwide have been brave enough to take on the motoring industry, promoting disruptive transport innovation ($2.7 trillion global market value 2021). Why not the food industry ($ 8.7 trillion global market value 2021).

Alternatively, could DLP focus their energy on bigger fish such as Coca-Cola and Pepsi, who inflict far more damage on our nation's smiles than any stressed-out individual dentist. The Tobacco companies settled for a minimum of $206 billion in 1998 in the USA.
