When you buy the packets they have sugar, or when you add sugar you are defeating the purpose of a meal to lowering total cholesterol because sugar will raise your
triglyceride level. Remember total cholesterol = LDL+HDL+1/5 triglycerides. Whenever adding sweetness, do whole food sweetness to get the most/total nutrition like fruit, dates, etc. The cardiologists that have had success with diet to control heart disease are the ones that prescribe a whole food plant based diet with no added oils.
Oatmeal is already 6% fat so be very carful on adding nuts. Optimum benefit, instead of nuts, add ground flaxseed meal.
"Flaxseed meal contains omega-3 essential fatty acids, lignans and fiber. Omega-3 essential fatty acids are “good” fats that have been shown to have heart-healthy effects. Each tablespoon of ground flaxseed contains about 1.8 grams of plant omega-3s. Lignans have both plant estrogen and antioxidant qualities. Flaxseed contains 75 to 80 times more lignans than other plant foods. Flaxseed Meal is high in dietary fiber containing both the soluble and insoluble types. It’s also a powerful natural cholesterol controller"
Whole flax seeds are hard to digest, ground flaxseed is better but optimum is freshly ground flaxseed that is refrigerated. I use my little bullet blender and put whole flaxseed in it and make a batch weekly.
Kiotikowboy, I'm not picking on you

Oatmeal and sugar and a handful of nuts is a better breakfast than eggs and bacon any day. I'm just looking for the optimum.
