Earth Balance, or any other new fangled tub spreads are not healthy. Even though they don't contain hydrogenated oils, they contain soy protein isolates which are not healthy.
I acutally don't recommend replacing butter in the diet. What I do recommend is that the butter you eat be organic so that you don't also eat hormones and pesticides that get absorbed into cow's milkfat and subsequently into the butter made from that milkfat.
My question to you would be why don't you want to eat butter? Have you (along with the rest of America) been a victim of the disinformation campaign that butter and tropical saturated fats are the root cause of heart disease and cancer? If so, then read on.
For millenia, butter has been a staple of the diets of supremely healthy peoples, and valued for its life-sustaining properties. Butter does not cause diseases, but rather protects against them. Heart disease was rare in America a hundred years ago. At that time the average amount of butter people ate was 18 pounds per year. Imagine, eating 18 pounds of organic butter per year and still being healthy!
Unfortunately, between 1920 and 1960 the amount of butter people were eating dropped to only 4 pounds per year. During that same time, heart disease rose to become the number one killer in America. How can it happen that when people eat less butter they develop heart disease at alarmingly higher rates than at any other time in human history?
Because butter (and it has to be organic butter these days) actually contains many nutrients that protect us from heart disease. First among these is vitamin A which is needed for the health of the thyroid and adrenal glands, both of which play a role in maintaining the proper functioning of the heart and cardiovascular system.
Butter also contains lecithin, a substance that assists in the proper assimilation and metabolism of cholesterol and other fat consituents.
Butter contains a number of anti-oxidants, especially Vitamin A, Vitamin E and the mineral Selenium, that protect us against the kind of free radical damage that weakens the arteries.
Butter also helps strenghten the immune system. The vitamin A in butter is essential in this role as well. The short and medium chain fatty acids (also found in coconut oil), have immune strenghtening properties. But hydrogenated fats and and excess of long chain polyunsaturated oils and many butter substitutes both have a deleterious effect on the immune system.
If you want to replace butter in your diet with an oil that is even more supremely effective, use extra virgin coconut oil. I recommend a combination of the two.
