The capsules have been developed to help this, too. I recommend after opening a fish oil supplement, you refrigerate them to ensure limited oxidation or destruction of the fatty acids. That's a good question. All fish aren't created equal, meaning all fish are not high in omega-3 fatty acids. Most foods contain saturated fat, monounsaturated fat, and polyunsaturated fats.
Vegetables primarily contain monounsaturated fat and polyunsaturated fat.
Again, these are the least harmful in cardiovascular disease. There is not a specific numeric value for fiber recommendation. However, I do like to see participants eating at least 30 grams of fiber a day. This usually means they are getting enough fruits and vegetables and whole grains, and beans or legumes, in their diet, which is a priority in the efficacy of the program. The average person in the US eats about 10 to 15 grams of fiber a day.
