Of course, that is usually said to those who want to maintain their homes, or their car.
It equally applies in the kitchen though.
Save money by eating out less, and eat more healthily.
Save money by cooking from scratch, and eat more healthily too.
It’s not a lot of use eating at home if all you do is eat take-out items or frozen TV dinners. For one, it won’t save you much money, and secondly, most take out food and packets of TV dinners are highly processed, with lots of added preservatives, colors, sodium and other junk like HFCS.
If you cook from fresh ingredients at home, you know exactly what you’re eating.
If you can buy organic meat, fruit and vegetables, it’ll still be less expensive, far healthier and much more nutritious than buying junk food.
Try planning ahead and you can save even more. For example, a larger chicken can last two days, and you oonly need to cook it once. As long as you properly refrigerate the leftovers you can have a healthy chicken salad the next day, or perhaps make some chicken fried rice (which will have a lot less sodium in than that from the Chinese take out). You an also use wholegrain rice, for added vitamins and fiber.
Try to work out what you’re going to eat for at least a few days, and then you won’t buy too much, and have it go bad before you eat it, particularly vegetables and fruit (as fresh meat can more easily be frozen as-is, whereas vegetables need to be prepared and blanched first before freezing).
