Re: Sat Fat Ratios

[Guest guest]

Tony, All,

Below, mentions his friend had limited her saturated

fat intake to 16g. This got me wondering. Which is more

important, the amount of saturated fat as a percentage of

total fat or total calories or neither (i.e., some constant

limit)?

Thanks,

The Hegsted equation is based on fatty acid ingestion as percentages

of total calories. This is why I said:

> the following effect on cholesterol for these oils at 10% of total

The only way to be able to quantify the amount (as grams) of fatty

acids would be to specify the total fat consumption. Knowing that a

2000-calorie diet has 30% fat, now you know that 600 calories come

from fat and this is equivalent to 67 grams of fat. If 60% of the

calories come from fat, these numbers double. In a diet with 134

grams of fat (1200 calories), 16g is only 12%.

Of course, when I read " 16g of saturated fat " I think of something

like coconut oil which is only 8% unsaturated. Most people think of

" saturated fat " as lard which is 54% unsaturated and they avoid it.

Instead, they eat butter which is only 32% unsaturated, and worse than

lard.

The important thing is to balance the amount of saturated fats with a

compensating amount of polyunsaturated fats while keeping the total

number of fat calories within the appropriate range for the diet.
