What is the optimal ratio of omega-6 to omega-3 fatty acids for a healthy diet?

In summary: 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.

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. :tongue: 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...

1. Is butter really bad for you?

No, butter is not inherently bad for you. In moderation, butter can be a part of a healthy diet. However, it is important to consider factors such as the type of butter and your overall dietary habits.

2. What are the health benefits of butter?

Butter is a good source of fat-soluble vitamins A, D, E, and K, as well as conjugated linoleic acid (CLA), a type of fatty acid that has been linked to various health benefits such as improved heart health and reduced inflammation.

3. Is there a difference between salted and unsalted butter?

The main difference between salted and unsalted butter is the amount of salt added during the churning process. Salted butter has a slightly longer shelf life and can add flavor to dishes, while unsalted butter is more versatile in cooking and baking.

4. Can butter be a part of a weight loss diet?

While butter does contain a high amount of calories and saturated fat, it can still be a part of a weight loss diet if consumed in moderation and balanced with other healthy foods. It is important to consider your overall calorie intake and to choose healthier cooking methods, such as using butter in small amounts or opting for alternatives like olive oil.

5. Are there healthier alternatives to butter?

Yes, there are several healthier alternatives to butter such as olive oil, avocado oil, and nut-based spreads. These options are lower in saturated fat and may offer additional health benefits. However, it is important to consider the ingredients and choose options without added sugars or unhealthy additives.
