This common fruit helps prevent heart attacks and stroke

Font Size:

A new study from the University of Alabama, Birmingham, USA, has found that adequate potassium-rich foods such as bananas and avocados prevent arteries from hardening and reduce the risk of fatal blockages.

The research found that when mice were fed potassium-rich foods, they experienced reduced stiffness in their aorta, the body’s main artery. Previous research has already revealed that stiff, inflexible arteries increase a person’s risk of suffering a heart attack or stroke, and researchers believe potassium regulates genes that maintain artery flexibility.

The study used mice who were at-risk of heart disease and each mouse received a high-fat diet. Different mice were then given either low, normal or high levels of potassium throughout the study.

“The findings have important translational potential, since they demonstrate the benefit of adequate potassium supplementation on prevention of vascular calcification in atherosclerosis-prone mice, and the adverse effect of low potassium intake,” said Paul Sanders, professor at the University of Alabama to the Daily Mail.

After reading the results of this research, will you start adding bananas or avocados back into your weekly diet?

      Triss it depends on where you are, they don’t like frost much or wet conditions so look it up on the net for your area. You may need to plant them on a mound and use cloth for frost when they are young. Theyre not cheap but considering how much I eat I’ll get it back.

    I have haemodialysis three times per week, and must have a LOW-potassium diet. The dialysis already puts a strain on my heart, and with the foods the article extols being ruled out for me, then I’m in a high-risk category of having a heart attack (I guess). Indeed, many on dialysis die of heart attacks.

    Never took either one out of my diet! Avocados are excellent all round and one of nature’s wonder foods. Bananas are also excellent.
    I count calories and use both of these as part of that count.
    Elderly people need to make sure they have enough protein as well.
    We spread avocados instead of butter a lot of the time.
    Maybe more about health on here instead of some controversial topics that set off some comments and arguments.

      What’s wrong with a bit of controversy – makes us think about things we otherwise just accept.

      I agree go veg. It’s good to hear diverse opinion. It’s important to challenge your opinion. In this PC world it doesn’t happen any more. Everybody seems to be offended by hearing an opinion that isn’t the same as theirs.

    Love Advocados, try them with vegemite on toast. They are too expensive tho’ $2-50/3.00 each else would eat them every day.

      Try to avoid supermarkets. I look for most of my vege and fruit at markets and local greengrocers where you can buy bags or in bulk cheaper. May not look as pretty but healthier
      Always have eaten bananas and avos. Also love berry fruit. Buy when cheap and throw in the freezer. I plant some vege too. Have bags of tomatoes in my freezer to throw in meals as i simmer.

    On a different health topic, but one that may interest Lifechoicers, I have just purchased a Hurom HH Series Slow Juicer. This superb South Korean product does not violently chop up fruit but slowly squeezes it with a device called an augur, which slowly revolves at 43rpm, and prevents the pulp flowing in thus making clean pure juice. You can check out its operation on Youtube or go to http://www.hurom.com for more technical information. At the moment I am not eating solid food as I am on a 3 day juice diet. This hopefully will remove unwanted toxins from my system and tone up my skin while at the same time providing me with all the vitamins I require during these three days. It is rather expensive at nearly $500, but if you weigh up its health benefits over a long period of use, perhaps you can justify the cost.

      There are many other cold press juicers for a lot less than $500 if you are interested. Just be careful though.

      Removing the pulp also removes much of the nutrition leaving a tasty drink that is high in sugar and high GI with none of the mitigating fibre and other nutrients. OK for short periods but care needs to be taken since we can drink more than we can eat (say 4-5+ pieces of fruit for a relatively small drink) making this a high calorie solution especially as most people will likely add way more fruit than vegetables (and the vegetables they do add are likely to more of the sweeter ones like beetroot and carrots).

      I agree KSS , eat the whole fruit.

      Sorry to say this, but juicing is not the best way to go. The body needs all the roughage (except the seeds) from the fruit. Juicing also concentrates the sugars which is not so good.

      Yes agree . Juice is way too much fructose without fibre . We’re supposed to only eat about 2 pieces of whole fruit a day. If you want to juice try veges rather than fruit but definitely only short term

    I like both these things, and will enlarge my intake of Bananas and Avocados!

      Yes like you John I too love both bananas and avocados – and will for sure increase my intake. Although my husband thinks avocados are totally tasteless whatever way I try to use them – thankfully he loves bananas.
      Just wish they would stay fresh longer in the dish – when they are cheaper would love to buy more, but it is keeping them fresh. Also wish Avocados were a bit cheaper – a little too expensive sometimes for us pensioners – so can only buy when on special.

    I used to love Avocados, until I developed what must be an allergy to something in them, and they cause me to vomit, however I do like bananas and a varied diet mainly vegetables. At 84 I still get around well and ride my bike when weather is nice.

    Avocado’s are a bit tasteless, but if you stuff them with something else you like, or spread on toast they are ok, I usually stuff them with prawns, don’t have them that often.

      A gourmet! I like that. Try avocado toast topped with lightly browned chicken livers. My grandma from old Russia taught me how to cook that!

    Sounds good, but I was told if I am taking arginine that you must not have foods with potassium. Do you know if that is true?
