According to Ayurveda, one must start meals with something sweet, eat something sour and salty in the middle and end with bitter or astringent flavours. Following this order can help alleviate health issues and promote wellbeing. Sweetness is a quality that has a generally positive effect on the expression of appetite, and this can lead to a facilitation of eating.
The taste buds to recognize sweetness is at the tip of the tongue. Sweet foods or desserts stimulate acid secretion. Acid secretion in the stomach facilitates release of hormones and enzymes that helps in breakdown of food. It is helpful to ignite the digestive fire at the beginning of the meal which is facilitated by eating something sweet. However, if this acid secretion occurs at the end of meal (for e.g. having dessert at the end of meal) it is likely to cause indigestion or bloating
When we are hungry, eating sweet helps overpower the vayu (wind) in the stomach, then sour and salty foods in the middle of the meal help stimulate the absorption in the small intestine. Finally, the pungent, bitter, and astringent taste helps subdue kapha dosh (earth).
Use jaggery, raw cane sugar or unheated honey as sweeteners for preparing desserts and traditional mithai. Excess of anything is bad, so moderation is needed while choosing sweets as well. But we are proposing that starting your meal with sweet foods is more likely to help regulate food intake and also improve digestibility of the food consumed.
