Adjusting and image Size to fit a div (bootstrap)

Try this way:

<div class="container">
    <div class="col-md-4" style="padding-left: 0px;  padding-right: 0px;">
        <img src="images/food1.jpg" class="img-responsive">
    </div>
</div>

UPDATE:

In Bootstrap 4 img-responsive becomes img-fluid, so the solution using Bootstrap 4 is:

<div class="container">
    <div class="col-md-4 px-0">
        <img src="images/food1.jpg" class="img-fluid">
    </div>
</div>

You can explicitly define the width and height of images, but the results may not be the best looking.

.food1 img {
    width:100%;
    height: 230px;
}

...per your comment, you could also just block any overflow - see this example to see an image restricted by height and cut off because it's too wide.

.top1 {
    height:390px;
    background-color:#FFFFFF;
    margin-top:10px;
    overflow: hidden;
}

.top1 img {
    height:100%;
}

Just a heads up that Bootstrap 4 now uses img-fluid instead of img-responsive, so double check which version you're using if you're having problems.
