Preventing Colorectal Cancer

Preventing Colorectal Cancer

okay so we've made it to the afternoon I just want to preface this that there are way too many slides to do this all in 15minutes so you do have the opportunity to get a copy of all the slides so that you can look at them and read through them in leisure especially the part that's more about the tips so we know that there are general guidelines for preventing cancer some by the American Cancer Society,

Preventing Colorectal Cancer

 others from the American Institute for cancer research and theWorld Cancer Research Fund look at more specific diet and cancer but we're here to talk about colon cancer and it just it's still true iron exercise is really probably the most important part of what we need to do this is some data from the recent update in looking at nutrition and colon cancer and looking at what evidence is actually pretty convincing and what is still only probable so we've combined the recommendations specifically for colon cancer from both the American Institute for cancer research and from the American Cancer Society,

 into these seven recommendations the first three are the kind of bad actors and the next are they more positive one so obesity we know that it does affect risk there have been several studies that have looked at this and there are a series of mechanisms that are proposed to be part of the reason why it can in caught what can cause cancer but the important thing then is so what do we do about it and how does it help and we do know that intentional weight loss is associated with the reduced in your risk increased is your sensitivity to insulin changes or hormones and it reduces that inflammatory state that may be contributing to the problem and there are classic ways to think about but you should look at and in your slide in your handouts you do have a nomogram,


Preventing Colorectal Cancer

 you can estimate your own BMI and the goal is to be within the normal range in addition to that in specifically for colon cancer there seems to be some association with abdominal fatness and so looking waist measurement is another aspect that you could think about measuring and can help in addressing your risk now easy to say how do we do that there are lots of different mechanisms, I'm sure you've heard about and have tried to implement but one of the things that are new that I think is really interesting and important are some of the new apps that are available either on your smartphones or you're on your computer things like losing it My Fitness Pal super tracker they're free on their places where you can go and input your what you're eating and it is that awareness of what you're eating each day that can actually really help keep your weight under control and lose if need be of course physical activity is part of helping you control and keeps the weight off as well as losing it,

 I think we have to remember that this is the environment that we live in before you can have a coffee and a muffin and it might have been 250 300 calories now if you have a latte and some of the bigger muffins it can be 800 calories in a day that's a500 calorie difference so just the sneaking portion sizes are something that we really have to think about when we'rethinking about weight this for you to look at what is a portion and for me one of the most important things to look at to remember to look at the facts labels on the products that you may be considering it's not just how many calories are in the serving,


Preventing Colorectal Cancer

  its how many servings are in the package I had somebody come up to me and they said well you know this drink only has 50calories right but she didn't understand that the drink contained two and a half serving so that drink had 10025 calories if she drank the whole thing understanding you're the number of servings and anything that you buy again important the next factor is the look is looking at red meat, there does seem to be data that soup continues to support the fact that red meat at red and processed meats may add to colon cancer risk and there are a variety of mechanisms that may be at the source of this some of it the fact that it has my urn which is linked to cell damage it could be the night Rossa means it could impart some of the ways the foods are processed but also to most of their process products you have extra salt and have nitrates,


Preventing Colorectal Cancer

which we know and nitrites associated with a risk so what to do the question is you don't have to completely avoid red meat that we're missing something here lamb so red meats include beef pork veal venison and lamb and it's not that you have to avoid it completely but the recommendation is to stay under 18 ounces per week and I think that's a fairly decent amount you could still have red meat in a reasonable size several times a week there is no recommended size and servings for your process meats so you know it's a continuum and we need to think about what we're going to choose more often if you've been to other talks that we've given here this you might have seen this slide before it is from the American Institute for cancer research and the idea,


Preventing Colorectal Cancer

 is can you move slowly from a plate that has been your traditional American plate 21 where at least half of your plate is vegetable quarter perhaps a whole grain and only a quarter of your plate a animal protein but the goal is you can move there slowly over time you don't have to do this right away so consuming a diet with an emphasis on plant foods has been recommended some data has shown get more Mediterranean diets their nature can have better outcomes and less risk even in patients who have colon cancer studies have been done by heart in his group and he showed that the western-style diet was actually assload associated with less recurrence and less mortality so the idea is kind of move slowly away from your standard American plate including more whole grains in your diet as well as fruits and vegetables and then the third actor seems to be alcohol and there's several mechanisms that may be involved with alcohol being a carcinogen what people often forget there is actually a very large contributor of calories in the US adult population,


Preventing Colorectal Cancer

 so the recommendation is to you are going to drink to do so in moderation and I always think well after you've had two glasses of wine who cares about the diet so you really want to think about it so what is a serving my friend here conveniently has found one that fits his bill but these are your standards what can standardly consider a serving of alcohol 12 ounces of beer five ounces of wine and 1.5 ounces of spirits the other is to again the calories I thought this was pretty interesting that a pina Coladas bet as many calories as a quarter pounder so the calories can sneak up on you physical activity that's one of our things one of the things we can do to help ourselves lots of different ways which it may decrease our risk it helps maintain our weight it improves the immune system it changes a hormonal,


Preventing Colorectal Cancer

 you and remember all of these things that we are talking about are things that can actually help us not only prevent perhaps colon cancer but other chronic diseases so the issue is can you think in terms of your leisure and occupational time as areas where you can add in some more physical activity and so everybody thinks of these right go into the gym and you know going for your walk but there are other things that you can do I actually have an exercise Ballin my office and I find I have much less back pain and discomfort with the ballon this is the pedal bikes these are other ways other combinations that you can think of how you can add a little activity into your day fiber has come and gone about being thought to actually work being convincing in reducing colon cancer it was out and then it's been back in but recently some more studies have seemed to cement if it's a benefit in reducing your risk and there's a different mechanisms definitely one is moving things more through more quickly through,

 the colon but other things may be changes in your gut bacteria so what can you do the the idea would be to increase your fiber intake and again you have a handout on ways todo that including also more whole grains because there's some interest specifically wheat brant as possibly being helpful so again the idea is to think about a healthy diet a varied dietless Western in its processed foods and more of an asst own focus on a plant-based diet and we know unfortunately single studies of nutrients have not been that successful but I will touch on a number that we have looked at vitamin D as mentioned before what we do

Preventing Colorectal Cancer



know is that vitamin D status tends to be low in patients who have been diagnosed with colon cancer but we don't know if it's causal we don't know whether it's the low vitamin D that causes the colon cancer is colon cancer-causing vitamin D but it does seem to make sense to think in terms of having your vitamin D level check and making sure that you can get yourself into normal range calcium and specifically, milk have both been associated with the decreased risk of ADnomas which are your precancerous lesions for some reason milk but not other forms of dairy seem to be associated with this and there's several ways that it can we think it can act but what is important to think about is that you know when you take a nutrient there are complications so the American the cancer society is very careful in recommending calcium for cancer,




Preventing Colorectal Cancer


 prevention because we do know that excess calcium is associated with increased prostate cancer risk something if you've been listening to the news we know that excess calcium may be actually bad for the heart so the idea is to try to stay within the guidelines of about 1,200 milligrams of calcium total from the day from your diet mostly and if you must supplement a load of the supplement so you don't go above and then garlic other than harming vampires what can garlic do as negative but there are a lot of different nutrients that are out that they were investigating that still, have not had enough data to be presented forward there's a little bit of data that shows that garlic can be helpful the interesting thing that I did not realize was that they actually do recommend that you cut the garlic chopped,

 it let it sit for 15 minutes and then cancer prohibiting enzymes seem to work a little a bit better if you do that soI never get a lecture without people asking you about well what foods what about organic and non-organic it's more important that you eat the fruits and vegetables that you get the fiber if you're if you're concerned about pesticides there is a great website from the Environmental Working Group and they call it you can just look up clean15 Dirty Dozen it's in your handout, they update,

Preventing Colorectal Cancer

 this every year and if you eat regularly the ones on this list well then maybe you want to consider at least half the time changing for organic again no single food can prevent you from getting cancer it is really an important lifestyle and there are somethings that I always think it's great for people to do want to think about regularly take advantage of the foods that are out there that are better that will make your life easier frozen vegetable example bring your sneakers with you so you can always have that opportunity to walk whether it's at lunch or after work don't waste your calories never travel without workout clothes and weigh yourself often and these are just some great websites for you to go to if you're looking for more specific information on diet and cancer thank you
