A diet that’s high in sugar leads to weight gain, high blood pressure and even cardiovascular disease. If you have a sweet tooth, Equal Stevia may be a healthier alternative. The natural sweetener is derived from the stevia leaf and each serving contains only 0.4 calories. One stick or tablet is as sweet as one teaspoon of sugar. $7.40 for a pack of 40 sachets; $12.35 for 200 tablets. Available at leading supermarkets and pharmacies.
