No meal can beat a homecooked one, one in which you have complete control over in terms of nutrition. This equates to control over a large part of your health and wellbeing.
Tips:
Make sure you have enough food from all five food groups.
Make sure your portions are small, but filling.
Always read the label on products when shopping.
Some frozen foods are almost as healthy as their fresh alternatives, such as frozen vegetables
Browning foods, through burning or charring, will make your food carcinogenic.
Lighter meals:
Porridge with sliced fruit and nuts.
Steamed vegetables, particularly nutritionally dense ones like broccoli.
Beans salad with wholemeal toast or brown rice.
As for condiments, I don’t usually season my food to reduce my salt intake. However, a tiny amount of iodised salt is recommended for your iodine intake.
(I also don’t use oil in my cooking, and my only cooking methods are steaming and boiling. If I do use oil, I use extra virgin olive oil that is cold pressed, this is a cooking or salad oil that contains a good balance of healthy oils like monounsaturated and polyunsaturated oils and undergoes minimal processing.)
Drink:
As a vegan, I lack omega 3 fatty acids, I get this from flaxseed meal. So frequently, I drink a glass of psyllium husk with flaxseed meal mixed into it. I am also an avid consumer of tea, particularly matcha tea. I generally drink low fat alternative milks like soy and oat milks, aiming for, if you are from Australia, a government approved 5-star health rating on all the products I consume.
Snacks:
Seeds, nuts, fruits of all types.
