Seems like the majority of fats are unsaturated so how is this different for exmaple from peanuts? Aren't unsaturated fats good in general? And it also has some of the Omegas, albeit very little of the important Omega 3.
So why is this so bad? Low fat mayonnaise mostly replaces the fats with carbohydrate (I'm guessing simple ones).
The reason why you'll see people express caution about mayonnaise and weight loss relates primarily to portion size. One tablespoon of mayonnaise is a very small portion, and I suspect that its very easy for people to exceed reasonable portion sizes without realizing their error.
Basically because the fat in mayonnaise is a processed fat, that's why it's unhealthy. There are some examples below that I found on the net (for comparison to your original question).
All saturated fat - solid fat from land animal products
All processed fats/oils - cooking oils, margarine, hydrogenated fat
All fats exposed to high temperature - fried, deep fried foods
Tropical oils - coconut, palm oils.
They make you fat
They make you tired
The shut off fat burning
They cause heart disease, strokes, cancer
Margarine (of any kind)
Salad dressings (Ranch, blue cheese etc)
All cream sauces: Alfredo, Bernaise, Hollandaise
Lunch meats and all processed meats
All commercially raised red meats
Regular whole eggs (free range are good)
Whole dairy products (milk, sour cream, cream)
Low fat dairy products (2% milk = 37% fat)
All processed oils (Canola oil, on-shelf vegetable oils)
All roasted nuts and roasted seeds
All peanut butter
Thanks for the post. But I also noticed on the list that there are peanuts and nut butters which are highly touted by health experts. Also, I wonder what "processing" actually does to the chemical stucture of these fats.
I honestly don't know to much about the specifics. To be honest, what 'really' is good for you these days???
Diet plans are so 'varying' that it's hard to really know what you should and shouldn't have. Some say 'apples' are perfect for a intake plan, others say you should STAY AWAY from them as well as other things like corn because they have a very high sugar content and don't 'break' down properly in the body. Seems everyone has a varying opinion on what is deemed 'healthy' and 'ok' to eat.... honestly there are some things that come up time to time that are recommended by many of the different plans so I stick with them. Things like cottage cheese for example, seems to be on most of the 'lists'.
I just watch the 'fat amounts' in everything I eat and eat sensible the whole time and that is what 'seems' to be working the best for me.
As far as the 'processing' as far as I feel, as soon as something is 'processed' it's a sign that you should watch what you are eating (in general). Not all processed food is bad but alot is. Think of it as a 'warning flag' in a way....
Ketchup is low in calories (around 15-20 calories per heaping tsp) but ketchup for the most part is high in sugar and average in sodium. There are alternatives but you do have to be reasonable and go easy. If your dumping a cup of ketchup on your food, that's a bad thing but what wouldn't be.
Mustard is extremely low in calories (around 3-5 calories per heaping tsp). It does have a very very small amount of total fat but nothing significant. Mustard also contains about 1/4 the amount of sodium compares to ketchup.
