Selenium is a co-factor in helping the effectiveness of fruit and vegetables fight these diseases. Selenium is rare in British soils, but is common in manure and manure-based fertilisers, and so is present in soils fed with these substances.
Therefore if you make your own compost adding some manure to your stack should do the trick. See our page Gardening Diary for tips on how to easily manage a compost heap.
Freshness is a major factor in the effectiveness of fruit and vegetables to fight disease, and the best way of getting the freshest produce available is to grow and harvest your own. There is nothing like the taste of a corn cob picked, taken straight to the kitchen, plunged into boiling water, cooked and eaten. Tomatoes picked, washed and sliced up into a salad. New potatoes, without the high price – and so it goes on.
