Diabetes It is a metabolic disorder caused by low or no secretion of insulin harmone which is secreted by the B-cells of langerhans of Pancreas in the body. By the deficiency of insulin, glucose is not-converted into glycogen leading to increased level of glucose in blood. This disease causes weakness and loss of weight of the body.

Dietary Management for hypertension is

• Calories People suffering from hypertension should maintain their body weight to avoid workload on arteries. Therefore, their diet should be of less calorie value.
• Fats Due to hypertension, the flexibility of arteries is reduced because of deposition of cholesterol in them. Therefore, hypertension patients should avoid animal fats and saturated fatty acids. Intake of unsaturated fats should be restricted to 40 gms.
• Proteins Hypertension patients should also avoid protein rich diet such as — meat, fish, egg and milk because protein rich food contains more of sodium also. They should restrict the intake of protein upto 20 gms only.

Induce a variety of fruits and vegetables in diet as they contain potassium and fibre. They have an opposite effect to sodiurn and prevent water retention, thereby reducing blood pressure.

When the soap molecules come in contact with water, the non-ionic part of a soap molecule attaches itself to the dirt on the fabric because the dirt is miscible in it. The ionic part remains in the water. The dirt is removed when clothes are rinsed many times with soap in clean water.

The scrubbing action helps in moving the detergent deeper inside the fabric and makes the dirt float on the solution. The dirt hangs on the tail of the detergent molecule and is removed by movement of water particles during rinsing.

Emotional changes happening in adolescent girls which influence their personality are as follows

• Due to Physical Changes Bodily changes in girls like onset of menstruation, growth of pubic hair and breasts etc can be confusing and scary, more so if they have no idea what is happening. Lack of awareness can lead girls to think that there is something wrong with them and make them feel embarrassed.
• Mood Swings The subtle changes in a girl’s feelings and emotions are due to the hormonal changes in her body. A girl will seem relaxed and reasonable at one moment and may lose her temper the next moment. Experiencing different emotions in a short span of time can be overwhelming and also confusing. It leads to frustration and anger, and may even lead to violence.
• Identity Crisis During adolescence, a girl is neither a child nor an adult. $he becomes conscious of the changes in her body. It is the time for experimenting and experiencing different things to know herself better and understand what makes her unique. The attempt to figure out who she is occurs due to the pressure to fit in.
• Change In Relationships An adolescent girl may start spending more time with peers than with parents. She may even feel embarrassed to be seen with a parent in public. For her, both friends and family are important. She wants the acceptance of her peers, along with the guidance and support of parents. She may start questioning and rejecting what their parents say and do.

For the family member suffering from diabetes, whole dal can be given to provide less protein and more fibre.
• Boiled Rice Add broccoli (for folic acid and zinc) to the rice as a garnishing for the lactating mother. For the diabetic, polished rice shoula De totally avoided, as it raises the blood sugar level. However, he can eat brown (unpolished) rice.
• Potato and Carrot Bhajiya The carrot gives Vitamin A and the potatoes give carbohydrates (giving energy), which are both essential for the lactating mother. The diabetic should only eat the carrots. The potatoes will raise the blood sugar; so he should avoid them.
• Chapati As the lactating mother needs more calcium, plain chapatis are inadequate. The dough of the chapatis should be mixed with paneer and then kneaded to give the additional calcium. The diabetic should eat chapatis made from coarse cereals like ragi or jowar. Fine cereals should be avoided, as they raise the blood sugar level.

Answer 25.
Usha can use the principles of design in the following manner for designing a sari and blouse for a working woman.

• Balance Formal balance can be achieved when structures and use of accessories are identical on both sides of the dress. This can be achieved in the blouse, as shown in the illustration below.
  
• Proportion This is the relationship of parts of a dress to one another and to the whole dress. This is based on the proportion of the golden mean which is represented by ratios like 3:5:8, 5: 8:13 and so on. In this case the ratio of the length of the blouse to that of the saree may be 3:5.
• Rhythm This can be achieved by repetition, gradation, radiation, parallelism or alternation. For instance, alternating red and green pleats in the saree will make the eyes travel smoothly from one part of the sari to another.
• Emphasis The centre of attraction in a dress is called the point of emphasis. In this case, it can be the neck of the blouse, where a continuing change in intensity from bright to dull, or from light to dark, can be made, as shown in the illustration below.
  
• Harmony This is possible when all elements of the design – lines, colours, form or shape and texture are related, consistent and in a sequence or order. For instance, both the sari and blouse can be made of silk.
