It is preventable through lifestyle changes.

Simply eat a well balanced diet.

No proof any of that stuff prevents colon cancer.

Eating lots of fiber may even cause colon cancer.

Majority of studies seem to point in the direction that a balanced diet free from processed meats and rich in grains, vegetables and fruit to be benefitial.

Former healthcare here and I would agree.  I'll provide some additional context:

1) most/all disease would be improved or even cured with lifestyle changes.  As i'm sure you can imagine, american adults aren't real good about making lifestyle changes - just look at allthe people who are overweight.  So you do the next best thing which is manage it via medication .. far easier to pop a pill than to eat better or exercise.

2) medical interventions that aren't pharmaceutical-based are gonna be labor- and time-intensive.  Hospital networks are looking to maximize their bottom line so they run bare-bones staffing numbers, which means you wont have staff on hand to carry out these other interventions.

With Covid, the data could not have been more clear that obesity was a primary factor yet the issue wasn’t even addressed,  and vaccines were deemed the be all end all.

Inflammation/irritation of the bowels is suspected as a cause of colon cancer.

Fiber appears to cause inflammation.  There is a lot of info about this on the web.

It goes against the accepted theories about dietary fiber.

"Red meat is a nutrient dense food providing important amounts of protein, essential amino acids, vitamins, and minerals that are the most common nutrient shortages in the world, including vitamin A, iron, and zinc.  Despite claims by the World Health Organization (WHO) that eating processed meat causes colon cancer and red meat probably causes cancer, the observational data used to support the claims are weak, confounded by multiple unmeasured factors, and not supported by other types of research needed for such a conclusion. Although intervention studies are designed to test the validity of associations found in observational studies, two interventions of low-fat, low-meat diets in volunteers that failed to find a benefit on cancer were not considered in the WHO decision.

60% carbohydrates is way too much and isn't balanced.  And unless it's mostly ultra-processed carbs, that's way too much fiber and plant anti-nutrients messing with your digestion and long-term health.

15% fat is way too low and isn't balanced.  You won't get enough essential fatty acids and fat soluble vitamins unless you supplement.

25% protein is too low for a bodybuilder, natty or not, or for any athlete.  That isn't balanced.  Protein should be minimum 30% for anyone, and that's pushing it.

There are essential amino acids we must get from dietary protein.  There are essential fatty acids and fat soluble vitamins we must get from dietary fat.

However there are no such things as essential carbohydrates:

“The lower limit of dietary carbohydrate compatible with life apparently is zero, provided that adequate amounts of protein and fat are consumed.”

Avoid sugar and flour, done.

Ill still get it done though. My uncle and my brother (47) both died from it, and normally its (can be) hereditary.
I did take some blood test where some can have "the gene" for it where its almost guaranteed you'd get it (or something like that).
(And was negative).
Both very east tests and Ill continue w/ them every 5-10 years. It has saved some people when caught early...

Nah, man, you're smart to do that.  My late father (RIP) and I clearly inherited intestinal diseases, and both of us were treated for diverticulitis.  In both our cases, our first rounds at the hospital saw us recover with antibiotics; five years later, we both had to go the colostomy bag route and, after a time, have part of our colons removed.  Didn't have the bag anymore and things are okay, but it was still a major setback for us both.

I'd just caution you to pick your surgeons veeeeeery carefully.  One local gal performed a colonoscopy on my aunt and wound up perforating her colon :/

Hmm...but what is a "balanced diet"?

The diet recommended by the Western medical establishment is about 300 grams of carbs a day.  Is that balanced?

But then why are obesity, diabetes, and gut issues an ever-growing problem in America?

Watch the video in my above post to find out.

https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/carbohydrates/art-20045705

The Dietary Guidelines for Americans recommend that carbohydrates make up 45% to 65% of total daily calories.

So if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbs a day.

Eggxactly!



By the definition of the word, a "balanced" diet would be

33.3 % Fat
33.3 % Protein
33.3 % Carbs

and

50% animal based
50% plant based

The 33.3% carbs with 33.3% fat would be perfect for making anyone obese and unhealthy very quickly.

Because Americans are lazy and stupid. Anything can be recommended but most will still stuff their faces with donuts and ice cream, and they won't exercise.

Yeah, where the hell are the health experts, TV shows, and books describing what we knew months into the spread of C-19?  Lose weight and exercise to reduce comorbidities and you’ll stay out of the hospital and live.  This should be shouted from the roof-tops.  We’ve moved from don’t fat-shame, to fat-acceptance, to fat is healthy.  FTN.

I think a balanced diet is just that. A good balance between all the essential foods.

There will never be a precise measurement, but just ensuring that one gets enough of good food and a blend of it, is the best we can do.

I don’t think there is any special diet. We have likely over complicated things. But, really, the best we can do is be conscious of what we eat and exercise. There is some part of luck involved in all of it.

If I had to throw out a ballpark number it would be Protein 20-25% with the rest split evenly between carbs and fat.

That said, it’s really a total calorie issue. A large surplus over an extended period of time is the main culprit in lifestyle related issues.

[loco]

If I had to throw out a ballpark number it would be Protein 20-25% with the rest split evenly between carbs and fat.

In my opinion, protein should be 30%-35% minimum, especially as we age.

As for mixing carbs and fat evenly, that's a recipe for disaster.  Choose low fat, or choose low carb.  Can't go low with both at the same time, can't go high/moderate with both at the same time.

Maintaining independence, quality of life, and health is crucial for elderly adults. One of the major threats to living independently is the loss of muscle mass, strength, and function that progressively occurs with aging, known as sarcopenia. Several studies have identified protein (especially the essential amino acids) as a key nutrient for muscle health in elderly adults. Elderly adults are less responsive to the anabolic stimulus of low doses of amino acid intake compared to younger individuals.

However, this lack of responsiveness in healthy older adults can usually be overcome with higher levels of essential amino acid (EAA) consumption.

The addition of nonessential amino acids to a supplement containing EAA does not result in additional stimulation of muscle protein synthesis [27], indicating that the quality of the protein, or its amino acid profile, is a key determinant of the functional potential of protein in muscle health. This is supported by several studies demonstrating that the ingestion of milk proteins, compared with the ingestion of soy protein stimulates muscle protein synthesis to a greater extent after resistance exercise, owing to the higher content of EAA in milk protein [28,29,30,31]. The data from the Health, Aging and Body Composition study support these findings [31], showing that intake of animal protein (with greater content of EAA), but not plant protein, was significantly associated with the preservation of lean body mass over three years in older adults.

The discrepancies in quality between animal and plant protein sources go beyond the amino acid profiles. When the energy content of the protein source is accounted for, the caloric intake needed to meet the EAA requirements from plant sources of protein is considerably higher than the caloric intake from animal sources of protein [36]. This is important to consider since obesity, especially with aging, is a major public health concern. Obesity is the most predominant factor limiting mobility in the elderly.

The consumption of dietary protein consistent with the upper end of the AMDRs (as much as 30%–35% of total caloric intake) may prove to be beneficial, although practical limitations may make this level of dietary protein intake difficult. The consumption of high-quality proteins that are easily digestible and contain a high proportion of EAAs lessens the urgency of consuming diets with an extremely high protein content.
