Dr Martin Scurr of The Daily Mail suggests that eating three tomatoes can help with stickiness of the platelets. This is in the answer to a question in today's health section in the copy of the Mail
"Why won't they unblock my neck arteries?" This was identified by a ultrasound scan on the neck. Very interesting reading.
There are different packages offered by private medical people like "Blue crest" who offer this scan service and I had it done few years ago.
In the health section there is a comment on five a day and portion!
