Healthy diet according to your genetics.

Hi everybody

I am new, so not sure how I should start....

I am 38 years old and I want to make sure that I eat good and have a healthy lifestyle to prevent any sicknesses. My mum is very sick(a lot of different sicknesses) and I am really afraid that my life can look the same in the future. There are so many "healthy" diets that you can get easily lost. I found very interesting genetics and it makes really sense for me that we should eat according to our genes. Just found an online shop where I could buy DNA test. Is there anyone who try DNA test before? I will appreciate any comments. :-)

  • Mammal requirements are surprisingly similar; majority fat, carbohydrate for intense activity, with just sufficient protein for repair and maintenance. That said, it is the gut that determines how food is synthesised. Herbivores may have several stomachs, and long intestines that allow vegetation to ferment and turned into usable fat by bacteria. Carnivores have shorter intestines because animal flesh needs much less digestion. Omnivores are somewhere between the two.

    As humans, our bigger brains prefer slightly higher amounts of carbohydrate in proportion to other mammals, however we still use twice as much energy in the form of fat compared to carbohydrate, and since our long intestines are much shorter in comparison to other great apes, ideally we need to derive this directly from our food.

  • Thank you for your time but not sure if you understand my question ;-) Was wondering if anyone of the group have done some dieting according to the genes. I am thinking about buying that test newlifegenetics.com/test-fi... and keep my diet according to results.

  • Interesting, worth try if you have €299 spare - however, not convinced it is value for money though. This seems to be based on a saliva test, I have seen another test based on a stool test which looks at your micobiome - article in the Telegraph Stella magazine some weeks ago. This one is quoted as £279 and I would think this is better value as it looks at your gut bacteria and advises you as to food types your body may be deficienct in. I think this is a little more rigorous a test.

  • Hi :-) That is very interesting, I believe that gut bacteria is so important. However, I think it is very expensive test as I can really use it only one time and in the future will need to do it again as bacteria will change. I am looking more for some key I could use it forever and even DNA test sound a little expensive it is not if you think that you can use it for rest of your life. I think I will go for it ;-) Thank you for advice.

  • Nowhere on this site does it show links to research to indicate the efficacy of following these diets, although lots of claims are made. That alone would make me suspicious.

  • Did you try to read a little about nutrigenomics? Nutrigenomics is a multidisciplinary science. Nutritional genomics, or nutrigenomics, is the study of how foods affect our genes and how individual genetic differences can affect the way we respond to nutrients (and other naturally occurring compounds) in the foods we eat. It is really making sense to me. I am totally thrilled by it, that's why I need my genetic test ;-)

  • I understand your question; I was trying to give you a logical perspective.

    It makes sense that our guts are suited to what we ate during our evolution, so a palaeolithic diet with minor variations according to culture will suit best. You don't need a £300 test to tell you that.

    If you eat real-food instead of processed junk you'll be on the right track. My explanation above is for the ideal proportions. phcuk.org/wp-content/upload...

  • I really try to keep healthy and balanced diet. I have tried last year to fallow Palaeolithic diet as well and I do not feel good with it, I always try to listens to my body, so I stopped after 3 months.

  • Agreed. Although our guts are adapted to this food, it doesn't necessarily supply what we need in the right proportions. We need twice as much energy from natural fat compared to carbohydrate, and not too much protein.

  • My view is that although genes influence your health, they do not determine your health. if you have extremely high cholesterol levels through inheriting a particular gene it doesn't matter what you do diet wise, you will not reduce your cholesterol. But you wouldn't need to spend money in order to find that out!

    Environment,as much as genes matter, so maybe it could be helpful if the familial pattern indicate strong pattern of particular diseases such as diabetes or heart disease or kidney disease or cancer. But again I am not clear of how successful following a particular suggested diet, other than generally a well balanced one is going to help on its' own. Look for good research based evidence before committing. Remember that there are a lot of people wanting to profit from other people's insecurities.

    I agree with bobaxford reply - a far more useful test would be gut health and/or consultion with a nutritionist, which is what I am doing for my diseases,

    Living well means a lifestyle that includes regular daily exercise, eating plenty of organic vegetables and fruit and little processed food and meat, good sleep patterns and good relaxation and enjoyment of life.

    My view is that you can do all of this without knowing your genetic make-up and believe you need to have good genetic Counselling before you take any genetic testing as there are often many uncertainties which can be thrown up which may cause you more worry and stress, and stress is one of the worst antagonists for a lot of diseases.

    Nothing is simple or predetermined.

  • That's very true. Dr Ron Rosedale says the difference between male and female involves about 200 genes, whereas each meal affects about 8,000 genes; one of the most powerful influences we have over how our genetic heritage plays out.

  • That's do not matter so much. Dr. Ron Rosedale have his points but he base his diet on leptin levels and our genetics have a big impact on that so I am back again to my genetic testing. The more I read about, more concern I am that I really need that DNA test but thank you very much for shearing your thoughts :-)

  • One last try ;-) he explains that carbohydrate/insulin has the greatest effect on leptin.

  • Sure it dose, but it have different effect on different people. It is little like with drugs, they effect all people on different way ;-)

  • And yet we are all recognisable as homo sapiens :-)

  • I believe that we are what we eat and definitely nothing is simple. I will try to contact that company and find out more before buy that test. Thank you for advice. :-)
