Discussion Overview

The discussion revolves around the optimal ratio of omega-6 to omega-3 fatty acids in a healthy diet, touching on the implications of dietary fats, particularly in relation to butter and oils. Participants explore various claims about the health impacts of different types of fats, including saturated and unsaturated fats, and their sources.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants question the health implications of butter compared to low-fat oils, suggesting that oils may be healthier due to lower saturated fat content.
  • Others argue that the nutritional content of butter, including its saturated fat percentage, is often misrepresented, with some claiming it is 100% saturated fat.
  • A participant provides specific nutritional data comparing butter and olive oil, highlighting differences in saturated and unsaturated fat content.
  • There is a discussion about the necessity of saturated fats in the diet, with some participants noting that certain fatty acids are essential and cannot be synthesized by the body.
  • One participant mentions the excessive ratio of omega-6 to omega-3 fatty acids in modern diets, suggesting that a ratio over 4:1 is unhealthy.
  • References to sources of omega-3 fatty acids, such as cold water fish, walnuts, and flaxseed, are made as potential dietary recommendations.

Areas of Agreement / Disagreement

Participants express differing views on the health implications of butter versus oils, the accuracy of nutritional data, and the necessity of saturated fats. There is no consensus on the optimal ratio of omega-6 to omega-3 fatty acids or the overall healthiness of butter compared to oils.

Contextual Notes

Participants reference various nutritional data sources, but there are discrepancies in the interpretation of fat content and health implications. The discussion reflects a range of opinions and uncertainties regarding dietary fats and their effects on health.

I see this article about a school dept. cracking down on the use of even small amounts of butter in cooking. Is there really medical evidence that "low" fat oils are healthier than the equivalent about of 'butter' in a balanced diet with normal amounts of daily exercise?

A shallow and quick google search for "is butter bad for you" shows mainly links showing it's actually better than most replacements.

I don't know but that article doesn't make sense: the school must use low-fat oil? I think oil contains more fat than butter per unit. Also, they should serve "peanut butter, jelly and cream cheese with bread", because it's less fattening than butter? Peanut butter contains lots of fats and oils, jelly lots of sugar. Cream cheese doesn't sound that healthy either.

However, I think it's good to limit the use of butter as an ingredient, often I had the impression that US restaurants use a couple of sticks per serving. Oil would be a healthier option, since one doesn't use the same amount and it lower on saturated fats.
 
I remember some years back when I studied nutrition a bit to learn how to eat healthier, I paid a lot of attention to how much saturated fat various foods have because my dietician had told me that was one of the things, along with sodium, that I wanted to keep to a minimum.

I was quite startled when I looked up butter and it said amount of saturated fat = 100%

In other words, as far as saturated fat goes, there ISN'T anything that can possibly be worse than butter (or taste better)

That can't be right.

According to USDA Food-A-Pedia

1 tbsp butter: 102 cal. 7 g saturated, 3 g unsaturated fat
1 tbsp olive oil: 119 cal. 2 g saturated fat, 11 g unsaturated fat

Hm ... maybe I misremember and what it said was FAT = 100%, not saturated fat.
 
While olive oil and canola oil are high in total fat, these oils are high in monounsaturated fat. Together with polyunsaturated fats, these are referred to as the "good fats". Saturated fat and trans fats are the so called "bad fats" which have been linked to atherosclerotic cardiovascular disease. As already shown, butter has higher proportions of the bad fats while the oils have the higher proportion of the good fats. It's not black and white. Polyunsaturated fats are a mixed bag and there is still controversy about their impact on heart disease. My Trader Joe's olive oil has 10g of monounsaturated fat, 1.5g of polyunsaturated fat, 2 g of saturated fat and 0 cholesterol and trans fat per serving.

Butter also contains about 16% water, so this can't be true either.

Ok, I've got it. The % of CALORIES is 100% fom fat!

No, because butter contains protein (milk solids) in addition to fat.

You can see it here. It's a small amount.

Huh. The site I looked at really quickly did say calories from fat = 100% so I guess they were throwing out what almost amounts to being a rounding error.

Still wrong. :-p If you look at a tiny amount, say a tablespoon, they do round it.

Maybe it's the butter content that was 100%

Saturated fats are also necessary...

There are just two essential fatty acids: alpha-linolenic acid (an omega-3) and linoleic acid (an omega-6). All others can be synthesized by humans. Both are polyunsaturated fatty acids (PUFAs). In modern Western diets, there is a considerable excess of omega-6 over omega-3 PUFAs (20-30:1). Current research indicates a ratio over 4:1 is unhealthy. Cold water fish, walnuts and flaxseed are good sources of omega-3 PUFAs.
