Limit trips to the grocery, cut down on your prep time, and serve a week full of delicious and nutritious meals. Keep dishes interesting. Use chicken, fish, seafood, vegetable, rice and pasta cooked in different ways such as fried, baked, grilled, boiled, braised, and steamed. Try out at least one new dish a week.
Keep meals healthy and simple. For breakfast, try pancakes and fruit shake; chocolate oatmeal and apples; cereals, fruit and milk; banana muffins and hot chocolate; yogurt, cheese and hot bread. Have at least two sets of 5 to 6 combo breakfast meal and rotate this on a weekly period. Jot down your grocery list. Categorize items into fresh produce, dairy, meat/fish, canned/bottled, etc. Have a grocery day and stick to it.
However, as we get older we need detoxification to avoid diseases. Eat only healthy food and supplements. This will flush dangerous toxins, cleanse and purify system, and increase vitality and energy.
