The cows will soon be in. They are starting to spend hours gazing over the gates across the lane from the foldyard, dreaming no doubt of self service at the silage clamp, but they can dream on for a while yet.

There is still lots of grass in the fields for them, so until the grass has stopped growing completely, and the cows have eaten up and need an excessive amount of supplementary hay, it is Cold Comfort Farm for them.

And despite all the horror stories of cows producing excessive amounts of methane gas and being the destroyers of the world etc, science, bless its heart, has found a silver lining to that particular cloud. Never mind the flatulence and statistics about methane emissions. There is good news, especially for cows like ours that are grass fed. The bonus is that, not only can dairy products from grass-fed cows be beneficial, but their meat is as well. I knew it was good to guzzle milk and slather butter on my crumpets. No double entendre intended.

Apparently scientists from leading universities here and abroad cannot find any convincing evidence linking eating saturated fats to a greater risk of heart disease. Even better, there are higher levels of a particular saturated fat that you get in cheese, milk and butter and any other diary product; margaric acid, which is associated with a lower risk of heart disease. Bring it on for the dairy industry. And even better than that, these lovely boffins could find no clear link coronary disease from eating beef or red meat reared on grass. Love ’em.

But, and there is always a but, meat from mainly corn fed cattle, as in the US, do demonstrate a higher rate of heart disease association. Probably emit more gas too. So, that is another good reason to only Buy British. Our grass fed cows are little stars and significantly good health providers. Pass the full fat cheese.

Even better, and you wonder can it get better, the scientific world has demonstrated through many studies that because you feel fuller, or satiated from a diet based around butter, high fat milk and cream, you are not replacing your calories on a low fat diet with refined carbs, such as pasta, bread or rice.

Coincidently, the Mediterranean diet, which is relatively high in fat with its reliance on olive oil, full fat yoghurt and cheese (and pasta, I can hear the muttering), with wine, is better than a spartan, no fun and frills low fat diet. Folk in the Med, have fewer strokes and a 30 per cent lower risk of a heart attack. So to me, and mine, all the sums about methane and dangerous dairy production from the trumps, burps and diets of our lovely cows, are just that. Hot air. Smelly though, I will admit.
