QUESTION: Is it good to avoid using oils in cooking? And what about nuts?

ANSWER: By avoiding the use of added oil and minimizing your use of nuts,
you can greatly reduce the fat content of your diet. Although vegetable oils
and nuts generally contain less saturated fatty acids compared with animal
fats (with the exception of coconut and palm oil), when it comes to calories
and possibly even hormone production, total fat is what matters—
regardless of whether it’s a “good” or “bad” fat. There are many ways to
prepare foods without oil, such as using water or vegetable broth for stirfries
and substituting applesauce, banana, or soy yogurt for oil or butter in
baked goods and desserts.15,16
