Hidden dangers of fruit! Seriously read this....

Pandorian

Maybe if they'd stop processing so many of our real foods and "let" us use the diet my grandparents did, you know the real butter, fatty meats etc, it didn't stop them from reaching 90+ years of age, the increases that are "seen" in athsma, allergies etc have got to be at least partly from our diets, because I sure don't have the same environmental factors on my 10 acres a mile from the nearest neighbour that someone living in the downtown of a city does yet people are getting the "same" issues come up... diets potentially the only thing in common since all our store bought meats are processed (or so it seems here in Canada, at one or two massive plants and stickered with different company logos.

I am reading a book on the 80/10/10 diet which is a raw vegan diet

It talks about why fruit is so good and most other things bad

The diet is 80% carbs most of which are fruit. I think it was saying that you are fine on tonnes of fruit iff you don't have loads of fat

The book has a lot of testimonials about people who were raw or vegan already but had lots of health issue. Once they cut-out the high volume of nuts/seeds/oils ie the things high in fat, these things were cured

The meal plans are interesting eg 10 banana smoothie!!!

It is keen that u get in all your calories, to do this from fruit you have to eat a massive volume and fat must be no more than 10%

Martina navratalova and Scott jurek ( ultra marathon runner) are two elite athletes to follow this plan

one thing i would like to say about fruit.. (and yes i believe it is a healthy choice to include it)..

i wish nutritionists etc would stop advocating X number of servings of 'fruit and vegetables' every day.

i WISH they would say something like' 5 or more servings of vegetables and no more than 2 servings of fruit' per day

i know my diabetic husband took their recommendation (combining fruit and veg in one group) as being free license to eat as much fruit as he wanted and to heck with the vegetables.. and nothing i could say to try to get him to rethink his approach works cause.. 'that's what the food guide says!'

In Australia, the recommendation is 'go for 2 and 5' - 2 serves of fruit and 5 serves of veg. I have to say, I am much more comfortable recommending this approach.

It just generalising from a minority to the majority.

The vast majority of healthy people who are not pre-diabetic can happily eat 3-5 portions of fruit a day with no ill effects whatsoever, and will benefit greatly from the fibre and the vitamins.

Diabetics and pre-diabetics will have to watch this more, but fruit on it's own does not result in people becoming morbidly obese and anyone who believes that is deluded about what else they were eating at the time and their corresponding lack of activity at the time!

Quote "Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats."

Notice it is a study with rats on a high-fat, high-calorie diet, examining fructose.

For most of us that eat normal, but moderate, and are not rats, there is no evidence here to avoid fruit.

But if you are on high fat, high calorie diet, avoid fruit. But I am sure a high fat, high calorie diet even without fruit, is going to lead to health issues.

For people that are sensitive, it doesn't take much fruit to raise insulin levels and it is also a known fact that too much sugar whether it is in the form of fructose or sucrose can lead to leptin resistance which makes losing weight and getting insulin levels under control.

I had an A1C of 8.9% and extremely high triglycerides. Limiting fruit to 1 small serving no more than 3 times a week, raising protein and fat intake and eating a lot of vegetables has my triglycerides down to 46 and my A1C is now 4.7%.

I was told by both an endocrinologist and a registered dietician to limit my fruit intake that much and to increase my vegetable intake, along with protein and natural fats.

If this article is more towards the more sensitive people then it should be stated that way. Not everyone is effected by fruit that way that you have been. You're all for this and saying that everyone needs to cut back on fruit, but not everyone has this problem that you had with fruits.

You can't just cut back or leave out a food group UNLESS, like you, you have a medical need for it. Not everyone has it, so there is no need to say that everyone should cut back. Its fruit, it's good for you! Yes it's filled with sugar, but those sugars are better than the sugar you would get from chocolate or a big bowl of ice cream.

I don't think it's right to say that everyone should cut back just from an effect it had on you.

I for one did not get overweight from fruit, and in fact I've been eating more fruit and have lsot weight. I don't think I could go without my apples, pineapples, grapes, or oranges.

My doctors had told me they have seen a lot of people that have went from having no issues to having issues with blood sugar and getting leptin resistance.

There is a direct correlation with people developing leptin resistance from eating too much fruit. There are a lot of vegetarians that have leptin resistance due to eating too much fruit.

There are more people that have blood sugar issues than anyone really knows. There are so many people that are undiagnosed it is not even funny.

Also, if you have anyone in your family that has Type 2 Diabetes - you are suspeptible to developing leptin and / or insulin resistance.

If your goal is to have optimum helath, then fruit intake should be curbed to be a "treat" or a dessert type item. That is all I am saying. If you don't care about being at your best health, then by all means continue with what you are currently doing.

And it is a known fact that sugar is sugar - no matter the source. The impact on blood sugar and release of insulin is the same no matter if it is fruit or a candy bar.

I am quite sure my doctor did not read an article and then tell me this. I have had more than 1 doctor talk to me about this and how it can start affecting people of normal weight or those that are not that over weight.

I don't avoid fruit, I just eat small quantities and very low glycemic.

That_Girl

This is absolute BULL!!!!. Yes your science is correct but your reasoning is flawed. Fruit is good for you. And part of the reason it doesn't raise insulin levels is because of all of the fiber and water in fruit makes the glucose absorbed at a slower rate. Unless you eat like 4 watermellons in a single sitting you will not be sending the glucose from fruit out of the liver as adipose tissue. We use the glucose from fruit fairly fast as it gets realeased from the intestine to the liver. Don't believe this anyone! 3-4 healthy servings of fruit a day is good for anyone. I agree that you shouldn't eat the whole watermellon is one sitting but its a hell of a lot better than eating the whole bag of chips. I eat lots of fruit, and have a 1400 calorie diet with a 1900 calroie BMR. I lose anywhere from 3-7 pounds a week when i stick to it. I am a pre-med student and i don't believe this crap you are trying to fed people. I have had so many biology classes and biochemistry classes and i don't believe your reasoning is correct. You have the right science but it would take huge amounts of fruit for the body to send it out of the liver as fat!!!! Limit refined sugar because that is the culprit here!!!!

:laugh: BRAVO!

I noticed that the OP only has about 7 posts at the time of posting this. So...whatever. I take it with a grain of salt..while I eat my apple. NOM!

ivyjbres

Pay special attention to this line: "If it is not needed for energy immediately, then it is converted into glycogen in the liver or muscles. The liver has the capacity to store 100 grams of glycogen. The muscles have the capacity to store between 250-400 grams of glycogen, depending on muscle mass and physical condition. Liver glycogen supplies energy for the entire body. Muscle glycogen only supplies energy to muscles."

That means that before any fructose can be stored in your fat cells, its must first fill up every cell in the body. Brain, intestinal lining, finger nail beds, skin, sweat glands, bone marrow, spine, nerves, growth plate, ligaments, tendons, everything. That means that to even gain a pound, I'd have to eat approximately 70 apples (BMR=1692+3500, divide by an average apple=75). That's if, and a very big if, my body even gets a chance to digest it all because the high fiber and water content means that well things will be moving through my system pretty quickly, and my bathroom ain't gonna be pretty.

Avoiding sugar (of all kinds, not just fruit) before a body building competition gives results because the body cells have to use more fat than is healthy to fuel itself because there isn't space fuel to borrow from the muscles, and the body cells have had their stores depleted. It may give results for a few weeks, but its not a healthy option in the long run. You'll start to see your hair, skin and nails get dull after a few months, and then it will get worse after that.

kaityray

Absolutely right! People are very jaded thinking that there is some sort of difference in fructose and refined sugar, its all stored as the same kind of sugar, bottom line.

Yes, the majority of people listen to the USDA, FDA and the corn counsil too much.

So... can we please have a show of hands from all those people who became morbidly obese from snacking on too many apples??? :huh:

lol so true!!

leslielove

Yes, the majority of people listen to the USDA, FDA and the corn counsil too much.

Yes yes yes yes yes. Why do you think whole grain products are so heavily advocated? Same with dairy and corn. The government wants people to eat that stuff (regardless of health benefit, which I am NOT trying to get into) because it so heavily subsidizes the production.

Fruit isn't all that its cracked up to be.

Pandorian

Maybe because the whole grains are "complete" not this enriched flour crap where they remove the good stuff and replace it with chemicals so the companies with subsidies can move their product.

Ever wonder why corn is in darn near every PROCESSED product?

I'll keep eating my fruit, avoiding refined products where I can. It's still a work in progress but choosing a fruit over my former choices IS healthier than what I used to be doing.

Corn and soy seem to be heavily subsidized, at least looking at the local farms around me for what they are growing, if there were money in the wheat, oats etc they'd be growing them but corn or soy are just so much more lucrative, it's almost all you see growing on any large farm.

Woodman725

Yes, I can say the amount of fruit I used to eat lead to my weight gain due to being insulin resistant and then becoming a full blown diabetic.

I used to eat at least 4-5 servings of fruit per day, plus a lot of low fat and low protein foods and I ended up gaining about 140 pounds.

Yes, this can obviously happen, you are proof. But your story, while relevant, is anecdotal. Can you gain lots of weight while eating a lot of fruit? Sure. Is it likely to happen? Probably not. I understand the article to say that eating fruit in moderation is okay, but excess fruit, juice or derivatives is not. It just proves that almost anything can be bad for you if you overdo it. If you drink too much water, you can die! That's a fact, but how much water do you have to drink for that to happen. Lets just agree that everyone's body reacts differently and eating fruit, even too much, is likely way better for you than eating a chocolate bar or having a whopper and milkshake.

soysos

one quick correction to your article. monosaccharides rarely exist in nature, and usually require a refinement process. the primary sugar in most fruits is sucrose, a disaccharide composed of fructose and glucose. almost every plant contains sucrose on some level. white table sugar is also sucrose extracted from sugar cane, or sorghum, or beats, believe it or not, but mostly sugar cane. it could jut as easily, and via the same process be extracted for apples, or oranges. if you are trying to watch your sugar, cutting back on fruity is a good idea.

all that being said your average serving of fruit contains less than half a serving of pure sucrose so two to three servings per day is not unreasonable.

Oishii

Did anyone else notice it mentioned 'three 8oz glasses of orange juice'? Now THAT is a lot of fruit sugar! It would take a lot of oranges to make that much juice. Warning off fruit JUICE would make more sense, if the rest of the article is correct.

I've never cared for this mantra. Arsenic in moderation will eventually kill you. Smoking in moderation can lead to cancer.

That being said, I still think that fruit is a better alternative to a chocolate bar because you're not just getting sugar, but also other vitamins and minerals that would have to be artificially added to a candy bar. Maybe in an ideal world, fruit would be considered a 'treat' but reality says that we should probably steer them away from heavily indulging in the cakes, candies, and other high colorie, low nutrient foods first.

you'd be surprised how much arsenic one consumes in a lifetime.

chocolate contains a lot of valuable vitamins and minerals as well, a couple of bites ever now and then is good for you.

And it is a known fact that sugar is sugar - no matter the source. The impact on blood sugar and release of insulin is the same no matter if it is fruit or a candy bar.

Sorry but sugar is not sugar irrespetive of source, because we use the term too generally. Sugar = sucrose (which is fructose and glucose). That is what is meant by sugar.

Fructose can occur on its own (monosaccharide), as can glucose.

The metabolic pathways for fructose and glucose are different. Fructose has a lower glyceamic index (19) compared to sucrose, and fructose (in the quantities one would get from a normal serve of fruit - which nature has so wonderfully packaged for us) does not trigger the same insulin response in the normal population, (and I exclude those predisposed to diabetes because there are other issues that have to be considered).

Fructose has gained a bad name from high fructose corn syrups, which have been used to sweeten many processed foods (which make us fat). These deliver fructose in an abnormally high level (ie not as nature intended). This causes problems, but it is not a "fruit" problem.

I love my fruit, and as I am not diabetic or pre diabetic, or overweight any more continue to enjoy my 3 or more serves each day.

Fruit did not get me fat before, neither did veggies. It was my eating way too much of a range of high calorie processed "stuff", once I stopped eating that and started with good fruit and veg on my plate, I killed my addictions to the stuff that made me overweight.

myofibril

I think the important part in the article is this sentence:

"If your goal is to exclusively to minimize bodyfat, then it is advisable that you consume more complex carbohydrates, which will go to replenishing muscle glycogen stores rather than fruit, which will only replenish liver glycogen stores, and is useless in muscle glycogen replenishment."

with emphasis on the part about your goals being EXCLUSIVELY minimising body fat or centered around that.

If you are on a short term "cutting" diet (12 weeks or less in my view) where one of your principal or only goals is to strip BF% then by all means cut out fruit and / or fruit juice fully.

However, if you are at the point of maintaining a healthy lifestyle and/ or dieting for more than a couple of months then the benefits of eating fruit outweighs the downside significantly for MOST people (although not all.) What that article fails to address are the benefits that fructose has in bringing liver glocogen back up to normal levels as well as the drawbacks.

If you are living with calorie restriction and exercising hard then you are probably in a liver glyocgen depleted state a lot of the time. Refuelling this store sends a "full" signal to the brain making over eating less likely. In addition, the fibre in fruit also promotes feelings of being full making over eating less likely. Let's also not forget the nutrients and vitamins found in fruit as well.

Finally I think that most people, even if they are on this type of diet or not, should key a close eye on their fruit JUICE intake (as opposed to fruit in its natural and solid state) as it is high in calories and sugar.

In short, the advice in the OP is useful for a small minority of people but not the majority.

I have many servings of fruit every day. In addition to the pounds I have lost, my blood sugar is no longer in a dangerous range, my cholesterol is now at a helthy level, and my body fat percentage has dropped drastically (more than 20% lost)

Fruit is good for you. Whole grains are good for you. A varied, produce filled diet is good for you.

Eliminating a whole food group, or restricting intake on it's perceived "bad" qualities is absurd.

I agree wholeheartedly. I also don't like when someone comes on here declaring they know the best, newest secret to health. It is stated as if everybody else is wrong, and if we just listen to them our bodies will morph into muscle bound atletes bodies.

Maybe if you are trying to lose every bit of fat for a competition, or some such goal, but for your average person who wants to lose weight, eliminating fruit as a snack or menu choice I feel is absurd. I'm not doubting the science behind glucose metabolism, but let's appreciate fruit for the healthy smart food choice that it is. Personally if I eliminated fruit as a snack, or side dish, it would likely be replaced with something less beneficial and be counterproductive to my goals.

Definitely!!
