Y tu hwnt i waharddiadau: Sut y gall dull sy'n seiliedig ar ganlyniadau fynd i'r afael ag argyfwng gordewdra Cymru

Mae amgylchedd bwyd Cymru ar groesffordd. Gyda chyfraddau gordewdra ymhlith plant yn uwch nag yn unrhyw ran arall o'r Deyrnas Unedig, nid yw'r angen am newid systemig erioed wedi bod yn fwy brys.

Yn 2025, cyhoeddodd llywodraeth y Deyrnas Unedig 'safon bwyd iach' newydd -polisi yn seiliedig ar gynnig Nesta ar gyfer targedau iechyd gorfodol i fanwerthwyr mawr. Drwy roi cymhellion i fusnesau bwyd mawr, gan gynnwys archfarchnadoedd, wneud newidiadau bach i'r hyn maen nhw'n ei stocio a'i hyrwyddo, mae gan y polisi hwn y potensial i leihau gordewdra o un rhan o bump heb gynyddu costau i ddefnyddwyr.

Ond sut mae'r polisi'n wahanol i bolisïau blaenorol sy'n wynebu'r diwydiant? Yn wahanol i bolisïau cyfarwyddebol blaenorol, sy'n aml yn canolbwyntio ar wahardd tactegau penodol fel prynu lluosog neu losin wrth y ddesg dalu, mae'r safon newydd hon yn seiliedig ar ganlyniadau. Nid yw'n dweud wrth fanwerthwyr sut i redeg eu busnes; yn hytrach, mae'n gosod targed iechyd clir ar gyfer eu cyfanswm gwerthiannau ac yn rhoi'r rhyddid iddynt ei gyrraedd boed hynny drwy addasu ryseitiau, prisio ffrwythau'n well neu gynlluniau siopau mwy craff.

Gyda Deddf Llesiant Cenedlaethau'r Dyfodol yn gosod dyletswydd gyfreithiol i wella iechyd ein cenedl, mae angen dull polisi arnom a all symud y nodwydd mewn gwirionedd.

Ddydd Mercher 25 Mawrth rhwng 12:00 a 13:00 GMT, aethom ati i ddarganfod pam na all Cymru fforddio cael ei gadael ar ôl ar bolisïau dylanwadol, fel y safon bwyd iach, a fydd yn sbarduno newidiadau i wella'r amgylchedd bwyd.

Roedd Andy Regan, pennaeth Nesta Cymru, yng nghwmni Sara Elias, cynghorydd polisi, a Manny Narula, pennaeth cyflawni polisi, yn archwilio:

  • Pam mae gwahardd 'prynu un, cael un am ddim' yn ddechrau da, ond targedau iechyd gorfodol yw'r hyn a fydd mewn gwirionedd yn ailgydbwyso basgedi siopa yng Nghymru
  • Pam mae cyfraddau uwch o ordewdra ac anghydraddoldeb iechyd yng Nghymru yn gwneud yr achos dros y polisi hwn hyd yn oed yn fwy brys nag yng ngweddill y Deyrnas Unedig
  • Sut y gall y safon ledled y Deyrnas Unedig ddarparu llinell sylfaen genedlaethol y gall Cymru wedyn adeiladu arni gyda'i strategaethau iechyd datganoledig ei hun
  • Sut mae'r polisi hwn yn ffitio i dirwedd etholiad 2026 a cham nesaf Pwysau Iach: Strategaeth Cymru Iach

Roedd y digwyddiad hwn ar gyfer llunwyr polisi, gweision sifil, ymchwilwyr a phawb sydd â diddordeb mewn trawsnewid yr amgylchedd bwyd yng Nghymru i wella iechyd y genedl.

The food environment in Wales is at a crossroads. With childhood obesity rates higher than in any other part of the UK, the need for a systemic change has never been more urgent.

In 2025, the UK government announced a new ‘healthy food standard’ - a policy based on Nesta’s proposal for mandatory health targets for large retailers. By incentivising large food businesses, including supermarkets, to make small changes to what they stock and promote, this policy has the potential to reduce obesity by a fifth without increasing costs for consumers.

But how is the policy different from previous industry-facing policies? Unlike previous directive policies, which often focus on banning specific tactics like multibuy or checkout sweets, this new standard is outcomes-based. It doesn’t tell retailers how to run their business; instead, it sets a clear health target for their total sales and gives them the freedom to reach it whether that’s through recipe tweaks, better pricing of fruit or smarter store layouts.

With the Well-being of Future Generations Act setting a legal duty to improve the health of our nation, we need a policy approach that can actually move the needle.

On Wednesday 25 March from 12:00-13:00 GMT, we found out why Wales cannot afford to be left behind on influential policies, like the healthy food standard, that will drive changes to improve the food environment.

Andy Regan, head of Nesta Cymru, was joined by Sara Elias, policy advisor, and Manny Narula, head of policy delivery, to explore:

  • Why banning ‘buy one, get one free’ is a good start, but mandatory health targets are what will actually rebalance shopping baskets in Wales
  • Why Wales’ higher rates of obesity and health inequality make the case for this policy even more urgent than in the rest of the UK
  • How the UK-wide standard can provide a national baseline that Wales can then build upon with its own devolved health strategies
  • How this policy fits into the 2026 election landscape and the next phase of the Healthy Weight: Healthy Wales strategy

This event was for policymakers, civil servants, researchers and all those interested in transforming the food environment in Wales to improve the nation’s health.
