Canola Oil
Is canola oil a healthy fat? Rightfully so since it had a bad reputation for awhile due to its association with a toxic acid called eurucic acid. More currently due to newer breeding processes reulted in its removal of this acid, making canola on the list of what is now called “healthy fats.” It is primarily an unsaturated fat and very low in omega-6 (fat and contain the same type of oil found in olive oil. However, Americans are awash in omega-6 fats and should be attempting to increase their intake of omega-3 fats instead.
But to its credit, it has a very mild flavor (unlike olive oil) and has been called a “neutral” oil so its very versatile for cooking and stands up fairly well to heat.

Roasting Vegetables
Roasting has become a cooking favorite lately, but questions do arise due to the higher temperatures (400 degrees) needed for best results. Many people wonder if this type of cooking can destroy some nutrients, especially in some originally healthy vegetables? This may help.
All forms of cooking can destroy some nutrients. It’s impossible to avoid. However, there is some good news since cooking actually helps by releasing the nutrients from plant cell walls. These include lycopene (iin tomatoes), red peppers and beta-carotene in carrots, spinach, and kale. Therefore, eating cooked tomaotes as a sauce or juice should be the preferred way for optimum health. Mushrooms, asparagus, and cabbage all supply more antioxidants when cooked.
Vitamin B6 and folate in broccoli and the polyphenols in onions that help protect against cancer and heart disease are better eaten as raw vegetables.
